Technical SEO FAQ · Indexing, Canonicalization & Duplicate Content
How do you determine why an important page isn't indexed?
Use a layered diagnosis:
- Does the URL return 200?
- Is crawling allowed?
- Is there a noindex directive?
- Is the page canonicalized elsewhere?
- Is it discoverable through internal links or sitemap?
- Is the content substantially unique?
- Does Search Console classify it as crawled/discovered but not indexed?
- Is Google selecting another canonical?
- Is the page newly published and simply awaiting processing?
Do not assume "not indexed" means a technical error. Google evaluates pages for suitability for the index after crawling.
