It was a bargain of a century for us

What are the best aspects of this product?

The fact that I solely manage 3 blogs successfully using just this tool tells a lot. I was skeptical first, considering how much functionality this SEO combiner has, and for the half of Semrush and Ahrefs price!
The keyword data is solid as I checked it back to back with Semrush's Pro package and in some cases even excels.
The rank tracker is very useful and handy on the go.
I seldom use other tools for my backlinks apart from Serpstat since I previously used Majestic and these are practically identical in terms of backlink data with Serpstat often showing even more results. So I ditched a few old tools and cut expenses by half using just this one tool!
Solid choice.

What aspects are problematic or could work better?

The keyword difficulty feature yet to be implemented for this to be a proper replacement to all tools I use for SEO.

What features/services would you like to see in future versions of this product?

Rank tracking, keyword/competitors analytics and backlinking tool with site health checkup (audit)
Basically, all of our companies SEO and part of our marketing automation is done with Serpstat

What specific problems in your company were solved by this product?

I'm using it for the lot - monitoring my ranking and competition, managing by backlink profile, checking my site health, and doing my primary keyword research.

Are you a current user of this product?
