GEO SEO checker: audit your AI + search visibility
By Abhijay Tondak, Founder & CEO · Updated July 4, 2026 · 6 min read
A GEO SEO checker is an audit tool that evaluates your website's visibility across both traditional search engines (Google rankings, indexation, technical health) and AI answer engines (whether ChatGPT, Perplexity, and Google AI Overviews cite your brand). It checks four dimensions: citation presence across AI engines, content extractability (can engines pull a clean answer?), technical readiness (structured data, crawler access, llms.txt), and authority signals (E-E-A-T, backlinks, corroboration).
Key takeaways
- A GEO SEO checker audits both search rankings AND AI citations — most SEO audit tools only do one.
- It checks whether AI engines can actually extract your content (answer-first structure, JSON-LD, crawl access).
- Run the check for your top 10-20 buying queries to find where you're invisible in AI answers.
- The output should be a prioritised action list: technical fixes first, then content gaps, then authority building.
- Citensity offers a free AI-visibility audit that checks all four dimensions in minutes.
What a GEO SEO checker actually audits
A traditional SEO checker looks at indexation, page speed, mobile-friendliness, meta tags, and backlinks. A GEO SEO checker adds the AI citation layer on top. It queries real AI engines with your target keywords and records whether you're cited, what position you hold, and what snippet the engine extracts.
The four dimensions a good checker evaluates: citation presence (which engines cite you for which queries), content extractability (is your content structured so engines can lift a clean answer), technical readiness (JSON-LD, robots.txt AI crawler rules, llms.txt), and authority signals (E-E-A-T markers, backlink profile, cross-web corroboration).
Why you need a combined check
You can score perfectly on a traditional SEO audit and still be invisible to AI engines. This happens when your content is well-optimised for ranking but poorly structured for extraction — long, meandering paragraphs with no direct answer near the top, missing JSON-LD, or AI crawlers blocked in robots.txt.
Conversely, you might appear in some AI answers but rank poorly in Google — meaning you're missing the organic traffic that feeds the authority signals AI engines use for citation decisions. The combined check identifies both gaps so you fix them together.

Run your free auditHow to run a GEO SEO check
Start with your most important queries — the 10-20 questions your ideal buyers ask when evaluating solutions in your category. Include both branded queries ('What is [your brand]?') and unbranded category queries ('best [category] tools 2026').
- Run each query in ChatGPT, Perplexity, and Google with AI Overviews — record whether you're cited and what snippet is used.
- Check robots.txt: are GPTBot, PerplexityBot, ClaudeBot, and Google-Extended explicitly allowed?
- Verify JSON-LD on your key pages: Article, Organization, FAQPage, and Product schema should all be present.
- Check for llms.txt at your root domain — the AI-crawler guidance file that tells engines what to read.
- Score each page for answer-first structure: does the first paragraph directly answer the query?
- Or use Citensity's free audit to check all of this automatically in 2 minutes.
What to do with the results
Group findings into three buckets. Quick wins: technical fixes like adding schema, allowing AI crawlers, or creating an llms.txt — these take hours and unlock everything else. Content gaps: queries where competitors are cited and you aren't — these need new answer-first pages. Authority gaps: areas where engines don't trust you enough to cite you — these need E-E-A-T investment like author bios, case studies, and third-party corroboration.
Frequently asked questions
Is a GEO SEO checker free?
Citensity offers a free AI-visibility audit that checks citation presence, technical readiness, and content extractability. No credit card required.
How often should I run a check?
Quarterly at minimum. AI engines update their retrieval logic frequently, and competitors are also optimizing — a stale audit misses both changes.
Can I check competitor visibility too?
Yes — a good checker lets you benchmark against 2-3 competitors for the same queries to establish relative share of voice across AI engines.
