A practical technical SEO checklist for indexing problems

When your site's pages aren't showing up in search results, the problem is often indexing, not crawling. This checklist walks through common technical issues like noindex tags getting left on live pages, sitemap entries with incorrect canonical URLs, and server blocks accidentally returning 403 codes to Googlebot. I use this myself whenever SEO audits turn up gaps between my indexed URLs and what I actually want in search.
