1. Open your Google Search Console account. If you haven't used GSC before, you'll be asked to add and verify your domain name.
2. Go to the Removals tab on the left, and click New request:
3. Insert the URL of the page you want to remove from Google search results, select Remove all URLs with this prefix, and click Next:
And that's it!
