What the result means
In Google means the exact URL showed up when we searched Google for it. The page is in the index.
Not found means the exact URL did not show up. This does not prove the page is missing from the index. Google search results vary by location and change over time, so a page can be indexed and still not show up in one search. If the page is on your own site, use URL Inspection in Google Search Console to confirm.
Cannot check and Check failed mean we could not search for that URL. Neither uses a free check or a credit, so you can fix the address or try again.
Check URLs in bulk
Free checks are limited to 3 URLs a day because every check is a real Google search. To check more, sign in with credits in your account. Paste up to 100 URLs at once and each URL uses 1 credit. A credit costs $0.20, and the same credits pay for submitting URLs for indexing. You can also run checks from your own code with the API.
Page not indexed? What to do next
First, check the page can be indexed. That shows whether the site lets Google visit it and whether the page tells Google to skip it. If your site uses Search Console, the Page indexing report explains every status, such as Crawled, currently not indexed and Discovered, currently not indexed.
When the page is ready, submit it for indexing. Each URL uses 1 credit, and if Google has not indexed it after the final check around day 14, the credit comes back. See Submitting URLs for how results work.
