warning robots.txt-disallowed URL receives internal links (crawl-budget leak)

Rule budget.disallow_linked · Budget · 1 occurrence(s)

  • https://rubywtf.com/random — internal links point to https://rubywtf.com/random, which robots.txt disallows for Googlebot — Googlebot discovers the URL, checks robots, then rejects it without indexing, wasting crawl budget and losing the link equity. Remove the internal links, or use noindex instead of Disallow if the page should be fetchable. Linked from: https://rubywtf.com/, https://rubywtf.com/post/43670123738/nl-in-ruby, https://rubywtf.com/post/20624075127.

warning Noindex page receives internal links (crawl-budget waste)

Rule budget.noindex_linked · Budget · 2 occurrence(s)

  • https://rubywtf.com/mobile — this noindex page has 22 internal inlink(s) — Googlebot follows them, fetches the page, then drops it unindexed, spending crawl budget for no indexing benefit (and the links leak equity). Remove/redirect the links, or drop the noindex if the page should be indexed. Linked from: https://rubywtf.com/, https://rubywtf.com/post/43670123738/nl-in-ruby, https://rubywtf.com/post/20624075127.
  • https://rubywtf.com/mobile/page/2 — this noindex page has 1 internal inlink(s) — Googlebot follows them, fetches the page, then drops it unindexed, spending crawl budget for no indexing benefit (and the links leak equity). Remove/redirect the links, or drop the noindex if the page should be indexed. Linked from: https://rubywtf.com/mobile.

Rule directives.noindex_via_x_robots · Indexability · 2 occurrence(s)

  • https://rubywtf.com/mobile — this page is noindex via the X-Robots-Tag HTTP header (not a meta tag) — set at the server/CDN layer and easy to miss. Confirm it's intentional; one broad rule can deindex a whole path.
