Today Matthew Woodward posted an article on his blog called Which Is The Best Backlink Checker SEO tool in the market today. His efforts were oriented towards finding out which SEO tool has the biggest backlink database in the world. So for this, he took what he believes are the top 5 SEO tools in the market for backlink analysis or; at least, what he considered to be the most popular. For the purposes of his study he picked... Ahrefs SEMRush Majestic SEO SpyGlass Moz And ren the same 1 million URLs into each of those SEO tools. I was very shocked to see the results. Spoiler Ahrefs came in LAST PLACE! Check out the study for yourselves. Looking forward to what you guys have to say about this. Cheers!
