    FAQ

    • What is a robots.txt file?

      Robots.txt is a text file at the root of your website that tells search engine crawlers which pages they can and cannot access. It’s the first file crawlers check before exploring your site.

    • What does this tool check in my robots.txt?

      We analyze every rule in your robots.txt, explain each one in plain English, check for common mistakes (blocking important content, missing sitemap directives), and specifically verify whether AI crawlers like ChatGPT and Perplexity can access your content.

    • Why does AI crawler access matter?

      AI search engines like ChatGPT, Perplexity, and Google AI Overviews need to crawl your content to cite it in their responses. If your robots.txt blocks AI crawlers, your content won’t appear in AI-generated answers — an increasingly important traffic source.

    • What should a good sitemap include?

      A well-formed sitemap lists all your indexable URLs in XML format, includes accurate lastmod dates so crawlers know when content was updated, and stays under 50MB / 50,000 URLs per file. It should be referenced in your robots.txt.

    • How often should I check my robots.txt and sitemap?

      After any major site change (redesign, URL restructure, new sections) and quarterly for routine checks. CMS updates and plugin changes can silently modify these files.
