TL;DR

If Google can't crawl a page, nothing else you do matters. Ten repeatable issues account for almost every hidden page on a real site — work this list once per quarter.

Key facts
  • Orphan pages (no internal links) are the #1 cause of unindexed content.
  • A single misplaced disallow in robots.txt can hide thousands of URLs overnight.
  • Redirect chains longer than one hop leak up to 15% of link equity.
  • Soft 404s tell Google a page is dead even when it renders correctly.

The 10-issue checklist

  • robots.txt doesn't block anything you want indexed.
  • XML sitemap exists and lists every canonical URL.
  • Every page has one clear canonical tag.
  • No orphan pages — every page has at least one internal link.
  • No redirect chains longer than one hop.
  • No soft 404s in Search Console coverage.
  • Meta robots and X-Robots-Tag headers aren't accidentally noindex.
  • JavaScript-rendered content is discoverable by Googlebot.
  • Faceted URLs don't create infinite duplicate pages.
  • hreflang is correct for multi-region sites.
Frequently asked questions
How do I find orphan pages?
Compare your sitemap against your internal link graph. Any URL in the sitemap with zero internal inbound links is orphaned.
Should I block AI bots in robots.txt?
Not by default. Blocking GPTBot, PerplexityBot or Google-Extended removes you from AI answers where your competitors will still appear.
