Now that we have a general idea of the links that you don’t want for your website, let’s get rid of them. In general, we have a number of ways of disabling these links so they won’t hurt your Google rankings: This is the easy one: find the contact details of the website owner and ask him to remove the link. Don’t demand the other website to take the link down, but ask this politely. That usually works better
However, you will most likely also be faced with webmasters who ask you to pay for link removal or who don’t reply at all. In such cases, you should disavow the unwanted links that can’t be removed.
