How audits are scored
Each audit runs a list of checks. Every check is a pass, a warning, a failure or a note.
- Pass1 point
- Warning½ point
- Failure0 points
- Notenot scored
The score is the points earned as a share of the scored checks, from 0 to 100. Some failures make the rest irrelevant, such as a page marked noindex, content that needs JavaScript or blocked AI search crawlers. These cap the score, however well the other checks do. 80 and above is strong, 50–79 needs work, below 50 is poor.
The three-score site audit runs the technical, content and AI, and agent audits on the same fetch; its overall score is the average of the three.
Our crawler
Server tools fetch pages with this user agent:
Mozilla/5.0 (compatible; AEOEngineBot/1.0; +https://aeoengine.in/bot)
- • Single-page tools fetch only the URL you enter, plus robots.txt, llms.txt or well-known files where the tool says so.
- • Site crawls (sitemap and llms.txt generators) follow robots.txt rules for the AEOEngineBot token and stay on the starting host.
- • The AI crawler access checker also requests the page once with each AI crawler's user agent, to see how your server responds to it.
- • Requests to private, local and reserved network addresses are refused.
To keep our crawler out of your site entirely, add a group for it to robots.txt:
User-agent: AEOEngineBot Disallow: /

Your data
- Browser tools (schema generators, prompt generator, answer scorer, crawler policy builder, bot log analyzer) process everything on your device. Nothing you type or upload is sent to us.
- Server tools fetch the public URL you enter and return the result to your browser. We don't store the pages or the results.
- Rate limiting keeps a count of recent requests per IP address in memory for one minute.
See the privacy policy for the full details.

Platform docs
The tracking platform (AI visibility, citations, prompt research, bot tracking and reporting) is in development. Setup guides for projects, prompts, integrations and exports will be published here when it launches. Until then, the guides cover the same work using the free tools.
