Enter all of your bad links now:
A disavow file is a list of all the links that have been pointed to your website in the past. It's a master list that you can use to disavow (remove) links pointing to your site from Google Search results. If you want to deprecate links that point to your site, you can use the disavow file generator to create a custom version of this list for each website, then run it through the disavow tool on Google Search Console. This will remove those links from search results and prevent them from being indexed in the future.
It can be risky for businesses to disavow links, as it could negatively impact their SEO rankings. However, if done correctly, it can be a great way to ensure that your website won't appear in search engine results when someone searches for your competitors' names.
