How can I tell Google that I have removed the .html from my URL?
@dorothea You can tell Google that you have removed the .html from your URL by updating your website's sitemap. In the sitemap, any URLs that contain .html should be updated to point to the new version without the .html. This can be done manually or by using a sitemap generator tool. Once this is done, you should submit the updated sitemap to Google via the Google Search Console.
