View PricingWhich tool do I need?
Each tool answers one question and reads one part of your site. If you are not sure where to start, work down the table — it is ordered the way a diagnosis usually goes.
| Tool | Question it answers | Input | What it reads |
|---|---|---|---|
| AI Crawler Access Checker | Can GPTBot, ClaudeBot, Google-Extended and the rest fetch this page? | A page URL | robots.txt, meta robots, X-Robots-Tag |
| Sitemap Checker | Do the sitemaps parse, and what is actually listed in them? | A domain or a sitemap URL | robots.txt Sitemap lines, /sitemap.xml, nested indexes |
| Canonical Tag Checker | Does this page nominate one live, absolute canonical URL? | A page URL | rel="canonical" and the status of its target |
| Meta Tags & SEO Checker | Will the title, description, and link preview survive a search result? | A page URL | title, meta description, headings, Open Graph, Twitter card |
| Structured Data Checker | Does the markup parse, and do the types carry their required properties? | A page URL | JSON-LD, Microdata, RDFa |
| AI Content Health Checker | How AI-readable is the content itself, dimension by dimension? | A page URL | Rendered text, scored across 9 dimensions |
| llms.txt Generator | What would a reasonable llms.txt for this site look like? | A domain | Sitemap entries and homepage metadata |
| llms.txt Validator | Does this llms.txt match the format? | A domain or pasted text | Headings, link syntax, duplicates, section size |
A sensible order to run them
Fixing a deep content problem is wasted effort if a crawler cannot reach the page in the first place. Work outside in.
- Access first — Run the AI Crawler Access Checker. A wildcard Disallow left over from staging makes every other fix invisible.
- Then discovery — Run the Sitemap Checker, and generate an llms.txt. Crawlers need to know the page exists before they can weigh it.
- Then interpretation — Canonical tags, meta tags, and structured data decide which URL is authoritative and what the page is about.
- Then substance — The Content Health Checker scores whether the page is worth quoting once all of the above is in order.
Terms used across these tools
Short definitions, in the sense these tools use them.
- GEO (Generative Engine Optimization)
- Work aimed at being retrieved and quoted by AI assistants rather than only ranked by a search engine. The unit of success is a cited sentence, not a blue link.
- AI crawler
- A bot operated by an AI company. Each one has a documented user-agent token and is controlled independently in robots.txt — training crawlers and answer-time fetchers are usually separate agents.
- Canonical tag
- A rel="canonical" link telling crawlers which URL is the authoritative version of a page. Missing or conflicting canonicals leave the choice to the crawler.
- Structured data
- Schema.org vocabulary expressed as JSON-LD, Microdata, or RDFa. It states in machine-readable form what a page would otherwise only imply in prose.
- XML sitemap
- A file listing the URLs you want discovered, with optional lastmod dates. It supplements link discovery; it does not guarantee indexing.
- llms.txt
- A proposed Markdown file at /llms.txt that points language models at the pages worth reading, in a form that fits a context window.
