What Does "Indexed by Google" Mean?
When a URL is indexed by Google, it means Googlebot has successfully crawled the page, found no signals blocking it, and added it to Google's search database. Only indexed pages can appear in Google Search results.
A page can exist on your website and still not be in Google's index. This happens through accidental noindex tags, robots.txt blocks, HTTP errors, or simply because Google has not crawled the page yet. Use this Google index checker to verify the real status of any URL.
Indexing vs Crawling
Crawling means Googlebot visits your page. Indexing means Google adds it to the search database. A page can be crawled but not indexed -- for example, if it has a noindex tag. A page blocked in robots.txt will not be crawled or indexed. Both must work correctly for a page to rank.
