There are two main things that make a good quality link and that is the metrics of that website (DA, DR, traffic, etc) and content – both of which are important but content more. Many people tend to focus on increasing their referring domain count without considering content relevancy and the metrics associated with that website. If you haven’t had a chance yet, you should research the issues that Rap Genius went through with their link building. To summarize, Rap Genius got thousands of links from any domain they wanted. They didn’t care about the metrics, the content, or anything else at all. They were getting around about 3,000 links from new domains every month. While the quantity isn’t exactly an issue, the issue was that it was being done on very questionable websites, most of which that were PBNs with high spam scores. We ensure that none of these issues are caused and have engaged in huge link-building campaigns where we have sourced over 500 links per month.
