I recently compared backlink data for 100 large US
domains. Now I did the same for 34 large domains from Germany
and 33 each from the UK
and France
. These are the results:

When it comes to the number of referring domains, @Moz is clearly in the lead. On average, Moz finds 98% of whatever is the maximum for each domain across all tools.

@ahrefs, @sistrix, and @semrush are doing quite good as well with 70% to 74%.
@Majestic is a bit worse with 59%. :-(

The correlation for domain-pop is very high with values between 0.94 and 0.99 amongst all tools.
This means that all tools will give similar impressions and trends when comparing multiple domains.

For the sheer number of links, @ahrefs is the clear winner at 70% - followed by @Moz and @semrush at around 63% each.
@sistrix drops all the way to the bottom with 20% - a sign of very efficient crawling that prioritizes domain-popularity over link-popularity.

When ignoring @ahrefs, backlink counts are correlated with 0.79 to 0.93 amongst all other tools.
With ahrefs, there is basically no correlation to what the other tools are reporting.

With the PageRank Replacement Scores, there is a lot of agreement between Domain Authority (DA) from Moz, Authority Score (AS) from SEMrush and Domain Rating (DR) from ahrefs.
Citation Flow from Majestic is all over the place.
