How to detect website indexation problems

Indexation issues happen when search engines cannot discover, understand, or keep the correct version of your page in their index.

Sometimes the page is blocked. Other times Google sees it but prefers another URL, or keeps dropping it because the signals are inconsistent.

Indexation failures often come from small technical decisions that compound over time.

Start with the page itself: inspect meta robots, canonical, headings, status code, internal links, and whether the URL belongs in the sitemap.

Then compare that with what search engines are likely seeing: inconsistent canonicals, weak internal links, or orphan pages usually stand out quickly.

If important pages are not indexed correctly, traffic never arrives in the first place. That means your copy, design, and CRO work never even get a chance.

These issues also create misleading reporting because teams keep optimizing pages that search engines are barely considering.

Fix the blocking signal first. Then reinforce the page with correct canonicals, sitemap inclusion, stronger internal links, and consistent URL selection.

After that, keep watch. Indexation often regresses after migrations, CMS changes, or content updates.
