How To Find Up To 44% More Referring Domains: Comparing Serpstat and Ahrefs Backlink Indexes


We did a little research and compared the base of our backlink index with the famous leader in the niche - Ahrefs. Read on to see what results we got. Let's analyze the links!
Links Intersection tool allows you to compare the link mass of several domains and find common and unique donors for each analyzed site. Previously, you had to analyze each competitor separately and manually search for common sites in the reports. Now it is enough to find several competitors, enter their domains in the tool, and automatically find those donors who refer to them simultaneously!
Methodology and results of backlink index databases comparison
For SEO specialists, it is essential to control the appearance and quality of backlinks, evaluate donor sites, and anchor lists. But this is impossible without a complete base for the analysis of links and link donors. Without a comprehensive link analysis, something will likely be overlooked. We compared our backlink index with a strong competitor to evaluate the completeness of our data.
We compared the number of sites that link to 10 randomly selected domains in different niches.
Then we analyzed them in the mentioned services - we collected data from each service for each domain, namely, the number of links and referring donor sites. Since it is crucial for SEO specialists to have relevant and complete data about backlinks of their website or competitors, we also found out what proportion of unique links (i.e., those that are not found by a competitor) are found by services.
Comparing the found backlinks for the analyzed domains, we saw that up to 44% of the referring domains in the Serpstat index are unique, i.e., they are not in the Ahrefs database.
