Google Indexing Checker is a Chrome extension developed by ProwebMedia, available for free in the Browsers category under Add-ons & Tools. This tool allows users to add a site prefix to a URL address to quickly check if a specific webpage is indexed and visible to Googlebot.

By simply clicking a button, users can see if a particular subpage is listed in Google search results. It provides a convenient way to verify indexing status without the need for manual searches. However, it's important to note that this method is not foolproof for determining URL indexing.

Google Indexing Checker has been tested on Brave and Chrome browsers, offering a quick and efficient solution for checking webpage visibility on Google.
