The best SEO, AEO and GEO checker extension for most users is SAGE because it combines technical SEO, answer-readiness, structured data, AI crawler access and machine-readability checks in one browser-based audit.
However, SAGE is not automatically the best choice for every workflow.
SEO / AEO / GEO Checker by PPCBlogPro is easier for writers and editors. Zicy is stronger for schema and AI crawler analysis. SellOnLLM adds optional AI citation tracking, while SEOFliq is designed for agencies that need competitor comparisons and branded reports.
The important point is that these extensions perform different jobs. Some inspect whether a page appears ready for search and AI systems. Others attempt to measure whether a brand is actually mentioned or cited.
A high readiness score can reveal useful improvements, but it cannot guarantee Google rankings, inclusion in AI Overviews or citations from ChatGPT, Gemini or Perplexity.
Best SEO, AEO and GEO Checker Extensions Compared
| Extension | Best for | SEO audit | AEO audit | GEO audit | Actual citation tracking | Free option |
|---|---|---|---|---|---|---|
| SAGE | Comprehensive technical and content audits | Strong | Strong | Strong | No | 25 complete scans |
| PPCBlogPro SEO/AEO/GEO Checker | Writers and editorial teams | Strong | Strong | Good | No | Yes |
| Zicy | Schema and AI crawler accessibility | Basic | Strong | Strong | Separate Zicy platform | Yes |
| SellOnLLM AEO/GEO Audit Tool | Page audits plus AI visibility monitoring | Good | Strong | Strong | Yes, paid | Yes |
| SEOFliq | Agencies and competitor reporting | Good | Strong | Strong | No | Yes |
Our recommendation
Use SAGE when you need the broadest audit.
Use PPCBlogPro when you want a straightforward content checklist.
Use Zicy when structured data and AI bot accessibility are priorities.
Use SellOnLLM when you also want to monitor citations and competitor visibility.
Use SEOFliq when client reporting and side-by-side comparisons matter most.
What is an SEO, AEO and GEO checker?
An SEO, AEO and GEO checker is a tool that reviews whether a webpage is technically accessible, clearly structured and easy for search and answer systems to understand.
The three parts of the audit have different priorities:
- SEO, or search engine optimization, focuses on crawlability, indexability, relevance, page structure and conventional search visibility.
- AEO, or answer engine optimization, focuses on whether the content answers specific questions clearly enough to be extracted or summarized.
- GEO, or generative engine optimization, focuses on whether generative search systems can discover, understand, verify and potentially cite the content.
These are not three completely separate disciplines.
Google says its generative search experiences remain rooted in its core Search ranking and quality systems. From Google’s perspective, optimizing for AI Overviews and AI Mode is still SEO, even when marketers call some of the work AEO or GEO.
That means a useful checker should not ignore traditional SEO. A page still needs to be accessible, indexable, relevant and genuinely useful before answer formatting or AI-readiness scores become meaningful.
How we selected these extensions
We reviewed extensions that are specifically designed to analyze SEO, AEO, GEO or AI-search readiness inside Chrome.
The evaluation considered:
- Traditional on-page SEO coverage
- Direct-answer and question-format analysis
- Schema and entity checks
- AI crawler accessibility checks
- Readability and content-structure analysis
- Exporting and reporting options
- Privacy disclosures
- Public ratings and adoption
- Whether the tool measures readiness or actual visibility
- How clearly the tool explains its limitations
The product information and Chrome Web Store data in this article were reviewed on July 18, 2026. User counts, ratings, features and prices may change.
We did not treat any extension’s proprietary score as an official Google, ChatGPT, Gemini or Perplexity metric. Google states that third-party tools do not have access to its internal ranking or AI systems.
1. SAGE – Best overall SEO, AEO and GEO checker extension
Best for: SEO and AIO specialists, developers, agencies and content teams that want one comprehensive audit
SAGE is the strongest overall option because it covers technical SEO, answer-readiness, generative search signals and machine readability without requiring several separate extensions.
The extension runs more than 200 checks across 15 categories and produces individual scores for SEO, AEO, GEO and its AI View. The developer says its page analysis is performed locally in the browser.
At the time of review, SAGE had a 4.7 rating from 12 reviews and approximately 433 Chrome Web Store users. Its free version includes 25 complete scans, while the Pro version removes the scan limit.
What does SAGE check?
Its SEO audit covers:
- Titles and meta descriptions
- Open Graph and social metadata
- URL structure
- Canonical URLs
- Heading hierarchy
- Internal links
- Image alt text
- WebP and AVIF image usage
- HTTPS and redirects
- Crawlability
- DOM size and render-blocking resources
Its AEO checks include:
- Question-and-answer formatting
- Featured snippet readiness
- Conversational language
- Sentence and paragraph length
- Readability
- Speakable schema
- People Also Ask-style coverage
Its GEO section reviews:
- AI crawler directives
- Structured data completeness
- Author and organization signals
sameAsproperties- Machine readability
- Content citability
- Accessibility signals for browser agents
SAGE also offers schema generation, a SERP overlay, score history and exports in HTML, PDF, Markdown, CSV and plain-text formats.
What makes SAGE useful?
SAGE does a better job than most lightweight extensions of connecting technical SEO with editorial content analysis.
For example, a writer can see whether the opening answer is unclear, while a developer can inspect canonicalization, schema or crawler-access issues in the same report.
The separate AI View is also useful. It attempts to show which page elements a machine is likely to encounter first, including the title, H1, headings, visible text, schema, links and images.
That does not recreate how a specific answer engine processes the page, but it can expose unclear or missing signals.
Where does SAGE fall short?
Its depth can make the report feel overwhelming for someone who only wants to edit a blog post.
SAGE also checks for llms.txt. That may be useful for services that choose to support the file, but Google explicitly says it does not use llms.txt as a special Search or generative-search signal. Adding the file does not help or hurt Google visibility.
Similarly, readability scores, keyword-density limits and proprietary GEO weightings should be treated as diagnostic guidance rather than universal ranking rules.
Who should use SAGE?
SAGE is the best choice for:
- Technical SEO professionals
- Developers
- Content optimization teams
- Digital agencies
- Website owners performing detailed audits
- Teams that want one extension instead of several smaller tools
SAGE verdict
Choose SAGE when: you want the most complete SEO, AEO and GEO checker in one browser extension.
Avoid it when: you only need a short editorial checklist and do not want a large number of technical recommendations.
2. SEO / AEO / GEO Checker by PPCBlogPro – Best for writers and editors
Best for: Blog writers, content editors and SEO teams that want a clear pre-publishing audit
SEO / AEO / GEO Checker by PPCBlogPro is less technical than SAGE, but its simpler approach makes it practical for regular content reviews.
The extension reviews title tags, meta descriptions, heading structure, topic placement, readability, internal links, external links, image alt text and basic technical signals. It then separates the findings into SEO, AEO and GEO categories.
It can also copy audit results or export them as JSON and CSV, which is helpful for editorial checklists, content-refresh projects and client reports.
At the time of review, the extension had approximately 1,000 users and a 3.0 rating based on two reviews. It was updated on June 26, 2026.
What does PPCBlogPro check?
The extension focuses on the elements most content teams review before publishing:
- Title length
- Meta description length
- HTTPS
- URL readability
- H1 usage
- Title and H1 alignment
- Main topic placement
- Content depth
- Heading structure
- Paragraph length
- Internal links
- External references
- Anchor text
- Image alt text
- Canonical tags
- Indexability
- Mobile viewport
- Social metadata
- Article and breadcrumb schema
Its AEO analysis looks for:
- Question-style headings
- Answers directly after questions
- Short-answer wording
- A top summary
- Definition support
- FAQs
- Lists and steps
- Conversational query coverage
- Comparison or decision support
The GEO review considers:
- Entity clarity
- Audience definition
- Author signals
- Publication dates
- Original-experience wording
- Examples and proof
- Statistics and data
- Source citations
- Organization schema
- Entity-disambiguation signals
What makes PPCBlogPro useful?
The biggest strength is explainability.
Instead of showing only a score, the report identifies which check passed, how many points it carries and what should be changed.
That helps writers understand why an improvement is being recommended.
It is also one of the few extensions in this category that clearly states it does not guarantee rankings, AI citations or traffic growth.
Where does PPCBlogPro fall short?
The tool is mainly designed for page-level editorial auditing.
It does not run ongoing prompts across multiple answer engines, confirm live citations or calculate a measured share of AI visibility.
Its rules may also encourage users to add summaries, FAQs or question headings even when those elements are not necessary for a specific page. The recommendations still require human judgment.
The public rating is based on only two reviews, so it does not provide enough evidence to draw a strong conclusion about long-term reliability.
Who should use PPCBlogPro?
It is best suited to:
- Blog writers
- Content editors
- Freelance SEOs
- Affiliate publishers
- Small business websites
- Agencies reviewing client articles
- Teams creating repeatable publishing checklists
PPCBlogPro verdict
Choose PPCBlogPro when: you want a simple, understandable content audit without a complex technical dashboard.
Avoid it when: you need live AI citation monitoring, advanced JavaScript analysis or deep technical crawling.
3. Zicy – Best for schema and AI crawler checks
Best for: Marketers and technical teams focused on structured data, answer extraction and AI bot access
Zicy is more focused on AEO and GEO than conventional SEO.
Its Chrome extension reviews AI readiness, schema quality, content extractability, authority signals and bot accessibility.
The extension uses seven main audit areas:
- Answer density
- Query fan-out coverage
- Semantic freshness
- Heading hierarchy
- Citation quality
- Author expertise
- Schema presence
It also checks more than 40 AI bots using robots.txt, meta directives, X-Robots-Tag headers and other access signals. Its schema tool can detect JSON-LD, Microdata and RDFa and generate markup for more than 15 schema types.
At the time of review, Zicy had approximately 437 users and a 4.5 rating from eight reviews. Version 2.9.3 was updated on May 8, 2026, and supported 12 interface languages.
What makes Zicy different?
Zicy gives more attention to extractability than a typical SEO toolbar.
Extractability refers to how easily a short section can be understood or quoted without losing its context.
For example, a strong answer paragraph usually:
- Identifies the subject clearly
- Answers the question immediately
- Uses complete sentences
- Avoids vague pronouns
- Includes the necessary qualifiers
- Can stand alone without the surrounding introduction
Zicy also provides schema recommendations based on the type of page being analyzed.
This can be helpful for teams that understand the difference between valid markup and useful markup. A technically valid schema block may still be irrelevant, incomplete or inconsistent with the visible page.
What should users know about Zicy’s privacy disclosure?
The extension description says it analyzes pages only when requested and does not track browsing history.
However, the Chrome Web Store disclosure lists website content, location and personal communications among the data categories the extension handles.
That does not prove improper data use, but businesses should review the current permissions and privacy policy before using the extension on:
- Password-protected content
- Client staging websites
- Internal company portals
- Private documents
- Pages containing personal information
This applies to any browser extension with access to webpage content.
Where does Zicy fall short?
Zicy is not as comprehensive as SAGE for traditional technical SEO.
It also places considerable weight on AI crawler access. Crawler access matters, but different bots serve different purposes. A crawler used for model training is not necessarily the same as a crawler used for live search retrieval.
Allowing every known AI crawler is therefore not a universal requirement.
Zicy also offers a wider AI visibility platform outside the extension. Users should distinguish the extension’s on-page readiness audit from the platform’s separate brand-monitoring capabilities.
Who should use Zicy?
Zicy is a good fit for:
- Schema specialists
- Publishers
- International content teams
- Technical marketers
- Companies reviewing AI bot access
- Teams improving author and entity signals
Zicy verdict
Choose Zicy when: schema, extractability and AI crawler access are your main priorities.
Avoid it when: you need a complete conventional SEO audit or prefer an extension with minimal webpage permissions.
4. SellOnLLM AEO/GEO Audit Tool – Best for audits plus citation tracking
Best for: Teams that want to connect page optimization with actual AI visibility monitoring
Most checker extensions stop after analyzing the webpage.
SellOnLLM goes a step further by offering both a free on-page AEO audit and an optional paid AI visibility feature.
The free audit checks technical setup, content structure, AI readability and citability on the active browser tab. No account is required for the basic audit.
Its paid AI Visibility plan can:
- Suggest buyer-focused prompts
- Suggest competitors
- Run citation checks
- Measure share of voice
- Compare competing brands
- Track historical changes
- Produce downloadable reports
The on-page audit remains free. A $5 one-time package includes 10 content generations, while the AI Visibility plan is listed at $10 per month. One AI visibility check is available without payment.
Why is SellOnLLM’s approach important?
A page-readiness audit and an AI visibility report answer different questions.
A page audit asks:
- Is the title clear?
- Can the page be crawled?
- Does the article answer its main question?
- Is the schema valid?
- Are sources and authors visible?
- Is the content easy to extract?
A visibility report asks:
- Did the brand appear?
- Was the website cited?
- Which competitor appeared instead?
- Which sources were used?
- How often did the result repeat?
- Is visibility improving over time?
This distinction is one of the most important gaps in many AEO and GEO articles.
A page can receive a strong optimization score and still fail to appear for real prompts. It may lack authority, relevance, indexing, external corroboration or sufficient retrieval demand.
The reverse can also happen. A trusted page may receive citations even though it does not follow every rule in an extension’s scoring model.
What makes SellOnLLM useful?
The extension provides a more complete workflow:
- Audit the page.
- Improve weak areas.
- Select relevant buyer questions.
- Monitor citations.
- Compare competitors.
- Track the result over time.
That is more useful than repeatedly improving a proprietary score without checking whether visibility changed.
Where does SellOnLLM fall short?
The ongoing visibility features require a paid plan and depend on external services.
AI answers can also vary by model, location, account state, search mode, wording and time. A single citation check should not be treated as a stable ranking.
Teams should use a consistent group of prompts and repeat the measurements over time.
The Chrome Web Store listing showed approximately 565 users and a 3.0 rating from two reviews when checked.
Who should use SellOnLLM?
It is best suited to:
- SaaS marketing teams
- Ecommerce companies
- Small agencies
- In-house SEO teams
- Companies entering AI visibility monitoring
- Teams that need both audits and outcome tracking
SellOnLLM verdict
Choose SellOnLLM when: you want to connect page improvements with actual prompt and citation tracking.
Avoid it when: you only need a fully local audit and do not want data processed by an external visibility service.
5. SEOFliq – Best for agencies and competitor reports
Best for: SEO consultants and agencies that need visual audits, competitor comparisons and branded PDF reports
SEOFliq is an ambitious free extension built around agency workflows.
It runs inside Chrome’s side panel and includes separate areas for AEO scoring, AI crawlers, schema inspection, content quality, page health, issue management and competitor comparison.
The extension can compare two URLs using:
- Overall AEO score
- Category scores
- Platform-readiness scores
- Word count
- Schema presence
- FAQ schema
- Author attribution
- HTTPS
- Canonical setup
- Content freshness
It also lets agencies add a business name, logo, contact details and brand color to downloadable PDF reports.
The developer says the main DOM analysis is performed locally. External requests are used to retrieve robots.txt and Google PageSpeed Insights data.
What makes SEOFliq useful?
The competitor comparison is its most practical feature.
Many content audits identify what is missing from one page but fail to show whether competing pages handle the topic better.
A side-by-side review can reveal that a competitor has:
- Clearer opening answers
- Better author attribution
- More complete schema
- Stronger sources
- More recent updates
- Better page performance
- More focused heading structure
SEOFliq also ranks issues by severity and allows users to mark recommendations as fixed or ignored.
That is useful for agencies managing multiple rounds of revisions.
Where does SEOFliq fall short?
SEOFliq is very new.
At the time of review, its Chrome Web Store listing showed only five users and no public ratings. Version 1.1.0 was updated on June 16, 2026.
This means there is not yet enough public evidence to assess its long-term stability, accuracy or support.
Some of its claims should also be interpreted carefully.
For example, it uses fixed word-count thresholds and per-platform readiness formulas. Google says there is no ideal page length for generative search and no requirement to divide content into artificial chunks.
Google also says third-party tools do not have access to its internal ranking or AI systems. A platform-specific readiness score is therefore the extension developer’s model, not an official score from the named platform.
There is also a difference between the developer’s “no data collection” description and the Chrome Web Store disclosure, which lists web history and website content as handled data categories. Users should read the permissions before installing it.
Who should use SEOFliq?
It may be useful for:
- Freelance SEO consultants
- Digital marketing agencies
- Client reporting
- Competitor page comparisons
- Pre-launch content reviews
- Teams willing to test a newer extension
SEOFliq verdict
Choose SEOFliq when: you want free competitor comparisons and branded reports.
Avoid it when: you need a mature product with a substantial user base and established review history.
Which SEO, AEO and GEO checker is best for your workflow?
| Your main need | Best choice | Why |
|---|---|---|
| Complete technical and content audit | SAGE | Broadest coverage across SEO, AEO, GEO and machine readability |
| Simple article review | PPCBlogPro | Clear explanations and practical editorial checks |
| Schema and crawler analysis | Zicy | Strong structured-data generator and extensive bot-access checks |
| Actual AI citation monitoring | SellOnLLM | Connects readiness audits with prompt and competitor tracking |
| Client reports and comparisons | SEOFliq | Branded PDFs and side-by-side page audits |
| Large-scale website crawling | None of these | Use a dedicated crawler such as Screaming Frog or a full SEO platform |
| First-party Google performance data | Google Search Console | Provides data from Google rather than a third-party readiness model |
What should a good SEO, AEO and GEO checker inspect?
The most useful checker is not necessarily the one with the largest number of checks.
It is the one that identifies problems that could materially affect discoverability, understanding, usefulness or measurement.
1. Crawlability and indexability
A checker should identify:
noindexdirectives- Robots.txt restrictions
- Canonical URLs
- HTTPS issues
- Broken redirects
- Mobile viewport problems
- Missing or blocked page content
- JavaScript rendering concerns
A page must be indexed and eligible to appear with a Search snippet before it can appear in Google’s generative search experiences. Meeting these requirements does not guarantee inclusion, but failing them can prevent eligibility.
2. Clear topic and entity definition
The page should clearly identify:
- What the subject is
- What category it belongs to
- Who created or owns it
- Who the content is for
- How it differs from similar entities
- Which facts define it
For a software review, this may include the product name, developer, features, pricing model, integrations, limitations and target user.
For a service page, it may include the provider, location, audience, deliverables and area of expertise.
3. A direct opening answer
A strong introduction should answer the main query before moving into background information.
For example:
The best SEO, AEO and GEO checker extension for technical audits is SAGE, while PPCBlogPro is better for simple editorial checks.
This gives readers an immediate answer and creates a passage that can be understood without reading the entire article.
Direct answers should still contain necessary context and qualifications. Overly simplified claims may be easy to extract but misleading.
4. Helpful question coverage
Question headings can improve navigation when they reflect real reader needs.
Useful questions for this topic include:
- What does an SEO, AEO and GEO checker do?
- Can an extension guarantee AI citations?
- Which tool checks AI crawlers?
- Which extension is best for schema?
- What is the difference between readiness and visibility?
- Is
llms.txtrequired? - How should results be measured?
Do not add questions merely to increase the number of AEO signals.
5. Original evidence and experience
A checker should look for evidence signals, but it cannot determine whether the evidence is genuinely useful.
Strong evidence may include:
- Original tests
- Screenshots
- Real examples
- Product limitations
- Publication and update dates
- Expert explanations
- Source citations
- Methodology
- First-hand observations
- Comparisons based on consistent criteria
Google recommends creating unique, non-commodity content that goes beyond restating information already available elsewhere.
A listicle that rewrites five Chrome Web Store descriptions is unlikely to offer much original value.
A better article explains how the tools differ, where their scores can mislead users and which workflow each product actually supports.
6. Relevant structured data
Structured data can clarify page entities and make content eligible for supported rich results.
However, Google says there is no special schema required for generative search, and structured data should not be treated as an AI-ranking shortcut.
For this article, suitable structured data may include:
BlogPostingArticleItemListListItemBreadcrumbListPersonOrganizationImageObject
FAQ schema should only be used when the questions and answers are visible on the published page.
7. Source and author signals
A good audit should check for:
- Visible author name
- Author biography
- Relevant expertise
- Publication date
- Last updated date
- Editorial policy
- Source links
- Organization identity
- Contact or About information
These elements help readers assess who created the content and whether it deserves trust.
They should not be added as decorative signals. An author biography is only useful when it provides truthful, relevant information.
8. Real outcome measurement
A readiness score should be supported by actual performance data.
Relevant measurements include:
- Search impressions
- Organic clicks
- Average rankings
- AI-referral traffic
- Brand mentions
- Source citations
- Competitor share of voice
- Conversion rate
- Assisted conversions
- Qualified leads
Google now directs website owners to use the Generative AI performance report in Search Console when the report is available for their property.
A page-readiness score is not an AI citation report
This is the most important limitation of SEO, AEO and GEO checker extensions.
A page checker analyzes what is present on the webpage.
It can identify:
- Missing metadata
- Weak heading structure
- Absent schema
- Blocked crawlers
- Poorly formatted answers
- Missing sources
- No author information
- Thin content
- Weak internal linking
It cannot know exactly how a proprietary answer engine will process the page.
Generative search visibility can involve several stages:
- Search activation
- Crawling
- Indexing
- Retrieval
- Reranking
- Context selection
- Answer generation
- Citation selection
- User interaction
A change that improves answer formatting may not improve retrieval.
A change that increases citation likelihood after retrieval may not help the page enter the initial candidate set.
The original GEO research found that certain content modifications could improve visibility within its experimental setup, but results varied by domain and did not establish a universal guarantee for organic visibility across every live platform.
A responsible workflow therefore separates:
Readiness measurement
This evaluates whether the page is technically accessible, clearly written, well sourced and easy to understand.
Visibility measurement
This checks whether the page or brand appears for real queries across search and answer platforms.
Business measurement
This determines whether the visibility produces qualified visits, leads, sales or other useful outcomes.
How to use an SEO, AEO and GEO checker correctly
Step 1: Run a baseline audit
Run the extension before making changes.
Save the report, scores and date so you can compare the page after editing.
Step 2: Separate objective errors from scoring preferences
Some findings are relatively objective:
- A page is marked
noindex - The canonical points to another URL
- An image has no alt attribute
- The H1 is missing
- JSON-LD contains an error
- Important content is not rendered
- Robots.txt blocks a crawler
Other findings are based on the tool’s own model:
- The page needs exactly 1,500 words
- Every article needs an FAQ
- Keyword density should reach a particular percentage
- A certain schema type always improves AI citations
- An 80 out of 100 GEO score means the page is highly visible
Fix objective technical problems first. Evaluate model-based recommendations using editorial judgment.
Step 3: Prioritize improvements by likely impact
A practical priority order is:
- Indexing and crawlability
- Correct search intent
- Clear and accurate main answer
- Original expertise or evidence
- Source quality
- Entity clarity
- Internal links
- Appropriate structured data
- Readability and formatting
- Minor score improvements
Changing a meta description from 158 to 155 characters is unlikely to rescue a page that does not satisfy the reader’s intent.
Step 4: Compare against actual competitors
Do not compare scores alone.
Review the pages currently receiving rankings, citations or strong visibility.
Ask:
- What evidence do they include?
- Are their authors more credible?
- Do they answer a narrower question?
- Are they cited by other sources?
- Is their information more current?
- Do they include original data?
- Are their explanations easier to understand?
- Do they have stronger topical support across the website?
Step 5: Make the page more useful, not merely more optimized
A checker may tell you to add a table.
The editorial question is whether a table helps the reader compare important information.
A checker may recommend an FAQ.
The editorial question is whether the questions resolve real uncertainty.
A checker may recommend more citations.
The editorial question is whether the sources support claims that genuinely need evidence.
Step 6: Rerun the audit
After editing, rerun the same extension.
Confirm that important issues were resolved and check that new problems were not introduced.
Step 7: Measure real performance
Track the page after publication.
Use a consistent set of queries and comparison periods. Do not judge success based on a single AI response or one day of ranking data.
Common mistakes to avoid
Mistake 1: Trying to reach 100 on every tool
Each extension uses a different scoring system.
A page may receive 91 in one extension and 64 in another because the tools apply different rules and weights.
The goal is not score agreement. The goal is to identify meaningful weaknesses.
Mistake 2: Treating all recommendations as ranking factors
A recommendation can be useful without being a direct ranking factor.
Short paragraphs, clear definitions and tables may improve comprehension. That does not mean Google applies a fixed score for each item.
Mistake 3: Adding an unnecessary llms.txt file
Some extensions check for llms.txt and may deduct points when it is missing.
Google says it ignores the file for Search, including generative search features. It can still be maintained for another system that supports it, but it should not be presented as a Google visibility requirement.
Mistake 4: Overusing FAQ and HowTo schema
Adding unsupported or irrelevant schema can create inaccurate markup.
Use schema that matches the main visible content. Do not hide content solely to generate additional structured data.
Mistake 5: Assuming every AI crawler should be allowed
Crawler names can represent different functions, including training, user-requested retrieval or search indexing.
The correct policy depends on the website’s content, commercial model and privacy requirements.
Review each crawler rather than applying one universal allow-or-block rule.
Mistake 6: Writing for a checker instead of a reader
Google advises website owners to focus on content that visitors will find satisfying, useful and reliable.
Repeated definitions, forced questions and unnecessary summaries may increase a score while making the page worse.
Mistake 7: Publishing unsupported “best” claims
A high-quality comparison should explain:
- How the tools were selected
- When the research was performed
- Which data came from product documentation
- Whether products were tested directly
- Which limitations were found
- How commercial relationships were handled
Without this information, “best” becomes a marketing claim rather than a useful conclusion.
Final recommendation
SAGE is the best overall SEO, AEO and GEO checker extension for users who want the widest range of technical, content, schema and machine-readability checks.
PPCBlogPro is the better choice for writers and editors who want a clear report without an overly technical interface.
Zicy is strongest for schema and AI crawler analysis, while SellOnLLM is the better option when page auditing must be connected with actual AI citation tracking.
SEOFliq is worth considering for agency reports and competitor comparisons, but its small user base means it should be tested carefully before becoming part of a client workflow.
No extension should be used as the final authority.
The strongest process combines:
- A browser-based readiness audit
- Manual editorial review
- Technical validation
- Search Console data
- Repeated AI visibility monitoring
- Real conversion and business metrics
That combination tells you more than a single SEO, AEO or GEO score ever can.
Frequently asked questions
What is the best SEO, AEO and GEO checker extension?
SAGE is the best overall choice because it combines more than 200 checks across technical SEO, AEO, GEO and machine readability. PPCBlogPro is easier for writers, while SellOnLLM is better for users who also need citation monitoring.
What is the best free AEO checker Chrome extension?
PPCBlogPro is a good free option for straightforward editorial audits. Zicy is useful for schema and crawler checks, while SEOFliq offers free competitor comparisons and reporting. SAGE includes 25 complete scans in its free version.
Can an SEO, AEO and GEO checker guarantee Google rankings?
No. These tools can identify technical and content issues, but they cannot guarantee rankings, traffic or inclusion in generative search. Google states that third-party tools do not have access to its internal ranking or AI systems.
Can an extension guarantee citations from ChatGPT or Perplexity?
No. Citation selection depends on factors beyond one webpage, including retrieval, relevance, source authority, prompt wording, system behavior and available evidence. A readiness score should not be interpreted as a citation probability.
Is GEO different from SEO?
GEO focuses on visibility in generative answers, while SEO traditionally focuses on search discovery and rankings. However, the two overlap significantly. Google considers optimization for its generative search features part of SEO because those experiences depend on core Search systems.
Is AEO the same as GEO?
AEO focuses on making content suitable for direct answers. GEO is a broader term covering visibility, citations and influence in generative responses. In practice, many tools use the terms interchangeably.
Does schema help with AI search visibility?
Schema can help systems understand entities and can support eligibility for Google rich results. It does not guarantee AI citations, and Google says there is no special schema required for generative search.
Do I need an llms.txt file for GEO?
Not for Google Search. Google says it does not use llms.txt as a special Search or generative-search signal. The file may still be used by another platform, but its absence should not be treated as a Google SEO error.
How often should a page be audited?
Audit important pages before publication, after major edits, after template changes and during scheduled content refreshes. Commercial pages and declining articles should be reviewed more frequently than low-priority content.
Which schema should be added to this article?
The most relevant types are BlogPosting or Article, ItemList, ListItem, BreadcrumbList, Person, Organization and ImageObject. FAQ schema can be added when the published article contains the same visible questions and answers.
