Add rules to robots.txt.

Test your changes

When you have made changes to your robots.txt, it is a good safety measure to check that you have not blocked anything you didn’t mean to. So check, for example, the web address of a category and of a product, as well as the one you wanted to block. You can use a free online tool such as the robots.txt tester from technicalseo.com (opens in a new tab).
