How Much Has Link Building Changed in Recent Years?

Posted by Paddy_Moogan

I get asked this question a lot. It’s mainly asked by people who are considering buying my link building book and want to know whether it’s still up to date. This is understandable given that the first edition was published in February 2013 and our industry has a deserved reputation for always changing.

I find myself giving the same answer, even though I’ve been asked it probably dozens of times in the last two years—”not that much”.

We use correlations against Google search result pages (SERPs) to track algorithm changes and the quality of our Mozscape index. We have published the results of these many times in the past, including the Search Engine Ranking Factors post and in the blog post announcing each monthly index update (see the September update). To summarize the process, we first take a set of keywords and run them through Google to collect the top 10 or 50 results. We then pull the link metrics from Mozscape for each URL in the SERPs (Page Authority, number of linking domains to the domain, sub-domain mozTrust, etc). Then, we compute the Spearman correlation between search position and each metric for each keyword. Finally, … Read the rest
