Editor's Take

I have used Semrush for three years and it is the one marketing tool I would not cancel. The keyword research alone justifies the cost — the 25B keyword database surfaces opportunities I cannot find anywhere else. The site audit tool caught technical issues that would have cost me thousands in lost traffic. That said, $129/mo is real money. If you are just starting with SEO, begin with free tools (Google Search Console, Ahrefs Webmaster Tools) and upgrade to Semrush when you are serious about growth. For agencies managing multiple clients, the Guru plan ($249/mo) with multi-project support is a no-brainer.
