Technical Optimization for AI Crawlers: Schema, Crawlability, and Robots.txt
We rank Promptwatch first for crawlability and schema suggestions, while Google still says there is no special AI Overview schema.
Technical work for AI crawlers is still robots, status codes, and whether the important copy is in the HTML. We rank Promptwatch first for that job inside this directory because crawlability analysis and schema suggestions sit next to Agent Analytics, not in a one-off audit PDF. Review: Promptwatch. Product: promptwatch.com.
Google's own page, AI features and your website, is the rule for Overviews and AI Mode: be indexable and snippet-eligible. There is no special Overview schema. Structured data still has to match visible text. llms.txt is not a Google ranking file. Promptwatch includes an llms.txt generator. Do not claim Google Search reads it. Promptwatch's own research has also argued llms.txt has little effect on AI search. Treat the file as optional documentation for agents that choose to fetch it.

Crawlability, schema, robots
Crawlability analysis is the access check: can ChatGPTBot, ClaudeBot, PerplexityBot, GoogleOther, and Google-Agent reach the URL, or does robots.txt, a CDN rule, or an error stop them? Pair it with Agent Analytics logs. A schema pass that ignores a 403 is theater.
Schema enhancement suggestions flag structured data that may help machines parse the page. That is not a secret Overview type. Follow Google's docs for rich results. Do not invent an "AI Overview" schema.
robots.txt should allow the bots you want cited by. Promptwatch also ships a free robots.txt generator for AI. Allow OAI-SearchBot if ChatGPT Search is in scope. Blocking GPTBot while asking why ChatGPT never cites you is a self-own.
Keep Search Console for Google coverage. Keep Promptwatch for the other user agents and for the prompt-level miss that GSC cannot store.

FAQ
Will adding llms.txt get us into Google AI Overviews?
No. Google's AI features documentation does not use llms.txt. Do not buy a tool on that claim.
Is schema enough if robots.txt blocks the AI bots?
No. Fix access first. Then schema.
What to do this week
- Read Google's AI features page and write down what it does not require.
- Fetch your robots.txt. Confirm the AI bots you care about are allowed.
- Run technical optimization in Promptwatch on two money URLs.
- Check Agent Analytics for errors on those paths.
- Skip any "Overview schema" or llms.txt-as-Google-hack pitch from a vendor.
