Indexability
Indexability covers every factor that determines whether a page can be discovered, crawled, and included in search engine indexes. A technically perfect page that is blocked by robots.txt, carries a noindex directive, or has broken canonicals cannot rank — regardless of its content quality.
The checks in this section span the full crawl and indexation lifecycle: from the first HTTP response through robots directives, redirect resolution, canonical declarations, hreflang language targeting, HTML structural requirements, and accessibility compliance. Together they ensure that every page you want indexed is accessible, correctly configured, and unambiguously identified.
Select a topic below to see exactly what the platform checks and how to resolve each class of indexability issue.
