Backlink Analysis: Ahrefs vs SEMrush

Backlink building is a challenging andyet one of the most rewarding off-page seo processes there is.
Link building helps you outpace your competitors. It isn’t something you’d want to realistically avoid, considering all the benefits attached to it.
By analysing backlinks of competitor domains you are going to rank higher than them.
Ahrefs remains a a big and the most accurate link checker there is and it has been for a couple of years. That said, SEMrush has caught up in a big way. There are dozens of improvements to the backlink index which is updated everyday.
So it isn’t an easy match between the two.
SEMrush’s backlink analysis features
SEMrush’s backlink analysis feature was a long-running joke. When they did an overhaul of their databases in 2019 that changed completely. This meant the backlink data was fresh and updated.

SEMrush’s backlinks database has now over 6.7 trillion backlinks that provides you with exception data on competitor backlink profiles.
It’s easy to start. Enter your domain to the search box and select backlinks from the drop-down menu. Hit enter. SEMrush will get you an overview of your entire backlink profile including the total number of links and also referring domains.

To obtain deeper insights go to the backlinks report by clicking on the referring domains. This helps you individually see all the individual domains in the link report.

In addition backlinks have type data like in body, image etc. There’s also attributes like follow or nofollow. You see the anchors as well.’
All of this carries through insights on competitor sites and how they build links.
As you enter a competitor domain what you see before you is the total overview regarding the backlink profile on the site. You see the total number of links and referring domains.
With the backlink audit tool you can run your entire backlink list through Google and see which of these links are toxic. It will generate a disavow file that you can submit to the search console.

Ahrefs seems to have a larger index. But that isn’t true for all sites and domains. In some cases the number of referring domains is larger for SEMRush.

SEMrush still remains a near second to Ahrefs at backlink tracing and analysis. Ahrefs makes it easy to obtain the right data.
Ahrefs has been providing backlink data for a long period now which is one of the reasons behind the accuracy.
