Why we like SEMRush:
It's hard to argue it's not one of the two best SEO tools out there. We've been using the paid version for a couple of years now and I like the interface and the way it formats the data in the dashboard. It's really hard to say it's better than Ahrefs, but it comes down to how well you can use the tools. You can't go wrong with SEMrush!

Why we likeAhrefs:
This is one of top two SEO tools in existence. Many elite pros use this tool. Between this and SEMRUSH is just splitting hairs. Some say Ahrefs backlink data goes deeper, some say otherwise. But the fact they offer a free version that do quite a bit, and their resources go on for days. It's learning curve and interface may seem more complex to a new user though.
