What This Metric Means for Your Site

Search engines abandon indexation when encountering redirect loops, line-level robots collisions, or conflicting noindex headers. Immediate root-cause diagnosis prevents traffic losses.

How to Improve Your Score (Actionable Fixes)

  • Eliminate intermediate 302/307 redirect hops to preserve crawl budget and equity transfer.
  • Audit robots.txt with RFC 9309 longest-match precedence to prevent unintentional line collisions.
  • Align HTTP transport headers (X-Robots-Tag) with HTML document meta robots tags.
  • Ensure HTTP 200 responses contain substantial content to prevent heuristic soft-404 tagging.
