SEMrush is a must-have tool if you are serious about SEO. I have been using on and off for over 10 years. We use the pro plan which is $69.95 per month.
The Information provided is normally very accurate. The UI looks a little bloated and it can be sometimes hard to find the right info required. I also find that the Paid Media data is not very reliable.
My favourite feature is that SemRush allows you to keep track of your competitors.
I use semrush alongside Ahref to give a consistent picture of the SEO landscape.
