SEO basics checker for AI-built sites
Last updated
Enter a URL to check the SEO basics AI site builders often miss: a missing or blocking robots.txt, no sitemap, template titles, missing descriptions, wrong canonicals, no social share image, an accidental noindex, leftover placeholder text and broken structured data.
Why AI-built sites miss these
Generators focus on the page you see. Files that search engines and AI assistants read first, such as robots.txt, the sitemap and structured data, are often missing or left as template defaults, and a noindex copied from a preview build can hide the whole site.
Questions
- Does this check AI crawler access?
- It reports a robots.txt that blocks all crawlers. A dedicated check for AI crawlers and llms.txt is planned.
