Enter a page address. We fetch it the way a crawler does and check every signal that can keep it out of Google.
Free, no sign-up. We fetch public pages only and store nothing.
A page Google cannot index gets no search traffic, however good it is. The causes are usually small: a noindex left over from a staging site, a robots.txt rule broader than intended, a canonical pointing somewhere else.
This check reads the same signals Google reads, so you can confirm a fix straight away instead of waiting for the next crawl.
That Google is allowed to crawl the page and add it to its index. It does not guarantee the page will be indexed or rank, since Google still judges quality and duplication, but a page that is not indexable has no chance.
robots.txt stops Google reading the page. noindex lets Google read it but tells it not to show it. Do not combine the two: if robots.txt blocks a page, Google never sees its noindex tag.
Usually a theme or plugin setting, or a duplicate page pointing at the original. If this page should rank in its own right, its canonical should point to itself.
Google Search Console's URL Inspection shows the index status Google recorded, the last crawl date and the canonical Google chose. Ergora runs that inspection for you once Search Console is connected.
