1. Crawlability
Can AI systems access your content?
Every major AI engine has its own crawler. Indexly reads your live robots.txt, checks for explicit allow/block per bot, and flags accidental blocks (a wildcard rule that silently blocks GPTBot is the most common one we find).
- GPTBot, ClaudeBot, PerplexityBot, Google-Extended, GrokBot, CCBot
- robots.txt + sitemap.xml validation
- JavaScript render-barrier detection
- Wildcard block detection — the silent killer
| Bot | Vendor | Status |
|---|---|---|
GPTBot | OpenAI | Allowed |
ClaudeBot | Anthropic | Allowed |
PerplexityBot | Perplexity | Allowed |
Google-Extended | Allowed | |
GeminiBot | Wildcard | |
GrokBot | xAI | Blocked |
2. Parseability
Can AI understand your content structure?
Crawling is half the battle. AI engines extract answers from structural patterns — schema, headings, definitions, FAQs, comparison tables. Pages without those patterns get crawled but never cited.
- Schema.org extraction — Article, FAQPage, BreadcrumbList, Product
- Heading hierarchy and definition-paragraph checks
- FAQ + comparison-table pattern detection
- Entity coverage scoring against your category
- Article schema
- FAQPage schema
- BreadcrumbList
- H1 → H2 → H3 order
- Definition paragraph in opening
- FAQ pattern detected
- Entity coverage (14 / 16)
- Comparison table

"headline": "Best AI tools 2026",

}3. Indexability for AI
Are you optimized for retrieval & citation?
Crawlable + parseable still doesn't mean cited. Indexability scores each page on the patterns AI engines actually pick: definition density, entity coverage, citable stats, schema completeness and external authority.
- Citation probability score per page (0–100)
- Definition density and entity-coverage scoring
- Citable-stat detection
- Per-page fix list ranked by citation lift
Top fixes
- Add entity coverage12 pages
- Add stat citations8 pages
- Add FAQ blocks23 pages
llms.txt & full-llms.txt
Generators for the AI-readable web
Two files AI systems look for first. Indexly generates both, refreshes them nightly, and serves them from your domain.
llms.txt Generator
Generates a clean llms.txt at /llms.txt — the canonical pages per topic, preferred entry points and a one-line summary AI systems can ingest in seconds.
- Picks highest-authority page per topic
- Writes compact, AI-readable Markdown
- Auto-serves from /llms.txt on your domain
full-llms.txt Generator
Builds the full-content variant at /full-llms.txt — every canonical page rendered as clean Markdown and concatenated for AI systems and training pipelines that prefer a single corpus.
- Renders every canonical page to Markdown
- Strips nav, ads and boilerplate
- Refreshed daily, served at /full-llms.txt
What customers say
Trusted by SEO and AI visibility teams
“We thought we were AI-ready until Indexly's audit caught GPTBot blocked by a wildcard in robots.txt and 38 pages missing schema. Two weeks later our citation share on ChatGPT doubled.”
Pim Broekstra
SEO Manager, Center Parcs
“The llms.txt generator alone is worth the price. We'd been hand-writing one — Indexly produced a better version in 30 seconds and updates it nightly.”

What is an AI Readiness Audit?
An AI Readiness Audit measures whether AI systems can access, understand and cite a website. Indexly's audit runs across three layers — crawlability (can AI bots fetch your pages), parseability (can AI extract structure, entities and answers), and indexability (are pages structured to be retrieved and cited). It scores each layer, lists per-page fixes, and ships an llms.txt and full-llms.txt generator.
Which AI bots does the audit check for?
GPTBot (OpenAI), ClaudeBot and Claude-Web (Anthropic), PerplexityBot, Google-Extended (Gemini and AI Overviews training), GrokBot (xAI), CCBot (Common Crawl) and Bytespider. The audit reads your live robots.txt, checks for explicit allow/block directives per bot, and flags accidental blocks.
What does parseability actually check?
Heading hierarchy, definition paragraphs, FAQ patterns, comparison tables, schema markup (Article, FAQPage, BreadcrumbList, Product) and entity coverage. AI engines extract these patterns to answer questions; pages that lack them are crawled but not used.
What is AI indexability?
Indexability is the probability that AI engines will retrieve and cite a page. The audit scores each page on definition density, entity coverage, citable stats, schema completeness and external authority signals — the same patterns ChatGPT, Perplexity and Gemini use to pick sources.
What is llms.txt and how does the generator work?
llms.txt is a proposed standard at /llms.txt that gives AI systems a compact, structured summary of a site. Indexly's generator inspects your sitemap, picks the highest-authority page per topic, writes a clean Markdown file and serves it from /llms.txt automatically.
What is full-llms.txt and when do I need it?
full-llms.txt is the full-content variant at /full-llms.txt — every canonical page rendered as clean Markdown, concatenated. It's used by AI systems and training pipelines that prefer a single corpus over page-by-page crawling. Indexly generates and refreshes it on a schedule.
How often should I re-run the audit?
Indexly re-audits every 24 hours. The dashboard shows a diff vs the previous run so you see exactly which pages improved, which regressed, and which AI bots changed their access posture.
How is this different from a traditional SEO audit?
Traditional SEO audits check Google ranking signals — Core Web Vitals, link structure, meta tags. The AI Audit checks retrieval signals — AI bot access, structured patterns AI engines extract from, citation-worthy content density and llms.txt presence. Both matter; only one is checked by traditional tools.
