Which should you choose?

Surfer SEO: Content optimisation tool with AI writing and SERP analysis.

Semrush: SEO and marketing suite for keyword research, site audits, rank tracking and competitor research.

The best way to decide is to run the same week of real work through both — most offer a free plan or trial — and compare how long tasks take, what your team prefers, and the total cost for your number of users including renewal pricing.
