Google will let you know that you have an Unnatural Outbound Links Penalty through their Search Console dashboard (formerly known as Webmaster Tools). If you have not yet signed up for Search Console, that is your first step.
Signing Up For Search Console
Search Console contains a lot of valuable information to you as a site owner, so signing up is a great idea even if you don’t suspect you have a penalty.
- Head over to http://www.google.com/webmasters/tools
- Once signed in, click on add a site
- You then to verify that you are the site owner using one of several validation methods. I always use the Upload a file to your server method. This requires FTP credentials, which you can get through your host’s dashboard
