What is disavow?
Disavow is a tool introduced by Google that allows webmasters to tell Google to ignore certain backlinks they believe are harming their rankings. The idea behind disavows is that it can be used when the webmaster has no control over the links and cannot have them removed in any other way. It works by submitting a list of URLs to the Disavow Tool via Google Search Console.
Once submitted, Google will consider these and ignore any links from those URLs when assessing your website’s overall link profile. This means they will not count towards your ranking or negatively affect it in any way.
When Google released disavow tool?
Google released its disavow tool in October 2012 to help webmasters combat negative SEO attacks and protect their websites against malicious backlinks. The tool enables users to submit a list of URLs that they believe are having a negative impact on their search engine rankings. Once the list is submitted, Google will ignore links from those URLs when assessing your website’s overall link profile. This means that these links will not count towards your ranking or have any other negative effects on your site. Additionally, this tool can help you eliminate manual penalization by Google due to poor-quality links pointing back to your website.
