Indexability refers to whether a search engine can actually add a webpage to its index — the massive database of pages it draws from when serving search results. A page can be perfectly crawlable but still fail to be indexed if it carries a “noindex” directive, is blocked by canonical tags pointing elsewhere, or is flagged as duplicate or low-quality content.
Crawlability and indexability are related but distinct: crawlability is about whether a search engine can reach a page, while indexability is about whether it chooses to store and rank that page once it gets there.
Regularly checking Google Search Console’s Index Coverage report is one of the most reliable ways to catch indexability issues early, before they quietly erode a site’s organic visibility.
Indexability checks are a core part of our SEO Audits & Reporting service.
