Hey,

To find out who has the biggest backlink database, I devised a real test.

I decided to:

  • Take the 5x biggest backlink databases on the market
  • Use them to collect data for the same 1x million links
To see who had the biggest – and bestest – database out there.

The result?

Ahrefs came in last place...

No other test has used a data set this large to compare Ahrefs, Moz, Majestic, SEMRush & SEO Spyglass.

But I'm glad I did - because there's a new king in town.
