What GEO readiness actually means
An AI engine can only cite a page it can reach, parse, and trust. seo·check checks the reach first: does robots.txt allow the AI crawlers — GPTBot for ChatGPT, ClaudeBot for Claude, PerplexityBot for Perplexity, and Google-Extended for Google's AI surfaces — or is a blanket rule quietly blocking them. A page that's invisible to the crawler can't be cited no matter how good it is.
Then it checks parseability and signals: JSON-LD structured data that tells the engine what the page is (an article, a product, a FAQ), and an llms.txt file that points AI agents at the content you want them to use. Together these are the difference between a page an engine can guess at and one it can read with confidence.
Why a separate tool from classic SEO
Classic on-page SEO and GEO overlap but aren't the same. A page can have a perfect title tag and clean meta description — great for the blue links — while blocking GPTBot in robots.txt and shipping zero structured data, leaving it effectively invisible to AI answers. The two checklists fail independently.
seo·check runs both and scores them separately, so you can see at a glance whether a page is winning on search, on AI answers, on both, or on neither. The GEO score is the part most tools skip, and it's increasingly where the traffic question is being decided.
Classic SEO check vs. GEO check
| Classic SEO check | GEO check (seo·check) | |
|---|---|---|
| Audience | Search index / blue links | AI answer engines |
| Crawler access | Googlebot in robots.txt | GPTBot, ClaudeBot, PerplexityBot, Google-Extended |
| Structured signals | Schema for rich results | JSON-LD + llms.txt for AI parsing |
| What you optimise for | Ranking position | Being cited in an answer |
| Often skipped by | — | Most legacy SEO tools |
frequently asked
- What is GEO, and how is it different from SEO?
- GEO is generative engine optimization — getting your page cited by AI answer engines like ChatGPT and Perplexity, rather than just ranked in classic search. seo·check scores both, separately, because a page can pass one and fail the other.
- Which AI crawlers does seo·check check for?
- It checks your robots.txt for the main AI crawlers — GPTBot (ChatGPT), ClaudeBot (Claude), PerplexityBot (Perplexity), and Google-Extended (Google's AI surfaces) — and flags whether each is allowed or blocked.
- Does a good GEO score guarantee I'll be cited?
- No. GEO readiness removes the blockers and adds the signals AI engines prefer, but no checker can guarantee a citation. seo·check tells you whether your page is eligible and well-formed, not whether a given engine will pick it.
- Is the GEO check free?
- Yes. The GEO score is part of the free report — no account, no paid tier.
