When you would use the info command (the syntax would be info:thrivesearch.com), you would see the canonical URL for a specific URL you entered using that info: syntax. The URL inspection tool will now show you the canonical URL for a URL you enter into it anyway. So Google said the info command is no longer needed.
The info command previously displayed not only the canonical URL view, but the links to the cache, similar pages, links (which they also killed off), web pages from the site and matching terms as well.
Here’s what it looks like currently:
Soon, when typing in the info command, results won’t be displayed at all. “We’ve also changed URL Inspection tool so that it will display any Google-selected canonical for a URL, not just those for properties you manage in Search Console. With this change, we’re also retiring the info: command. This was an alternative way of discovering canonicals. It was relatively underused, and URL Inspection tool provides a more comprehensive solution to help publishers with URLs,” Google said.
Now, when running a URL in the URL Inspection tool, it’ll display the user-declared canonical and the Google-selected canonical. The Google selected canonical is the URL selected by Google as the authoritative version of this page. Other versions can be served in search results, depending on factors such as the user’s device type or language. This is not available in the live test, as Google selects a canonical URL only after a page is indexed.
In order to see what URL Google thinks is the canonical URL, you have to have verified access to the site in Google Search Console and plug that URL into the URL Inspection tool. Previously, you were able to use the info command in the public Google search box.
