The file contains no "Sitemap:" line.

Consequence. Crawlers have to discover every URL by following links. Pages that are deep, newly published, or poorly linked internally take longer to be found, and some may never be. A sitemap is the most direct way to hand a crawler the full list.

If that is not intended. Publish an XML sitemap and declare it with an absolute URL, e.g. "Sitemap: https://example.com/sitemap.xml". The line is global — it belongs outside any User-agent group and applies to every crawler.

  "Disallow: /" blocks Baiduspider.

If that is the intention. If your intention is to keep the site out of the major search indexes, the current configuration achieves that for these crawlers — the rest of the group is still allowed.

Consequence. These search engines cannot crawl the site, so its pages will not appear in their results. Note that robots.txt does not remove URLs that are already indexed — it stops them being re-crawled.

If that is not intended. Remove the matching Disallow rule, or give these crawlers their own group with an Allow rule. Path matching is longest-wins, so a specific Allow overrides a broader Disallow.

  "Disallow: /" blocks Google-Extended.

If that is the intention. If your intention is to keep the site out of AI-generated answers, the current configuration achieves that for these crawlers — the rest of the group is still allowed.

Consequence. The site cannot be cited as a source in AI-generated answers. Unlike training crawlers these send referral traffic, so blocking them forfeits those visits.

If that is not intended. Remove the matching Disallow rule, or allow these agents on the sections you want cited.

If that is the intention. If your intention is to prevent this content being used as model training data, the current configuration achieves that.

Consequence. These crawlers cannot retrieve content from the site, so it will not be collected as training data. They send no traffic back, and blocking them does not affect search rankings.

If that is not intended. Remove the site-wide block, or replace it with narrower path restrictions.

All 3 checked user-triggered AI fetches are allowed at the site root.

All 5 checked social link previews are allowed at the site root.

The page sends no robots meta tag and no X-Robots-Tag header.

Every line parses as a directive crawlers understand.

Comfortably within the 500 KB that crawlers will read.
