Semrush
Overview
A research tool for online marketing that shows which search terms bring traffic, what competitors rank for, and how ads are performing.
General use
Marketers use it to plan search engine content, track keyword rankings, study competitors, and audit a site for search problems.
Insight
A broad toolkit for search marketing, good for competitor research and finding which terms to target. The traffic and ranking data is an estimate, sometimes well off, so treat the numbers as direction rather than truth. It is priced per user and gets expensive, with extra seats and features costing more on top. Best for planning and competitor checks, not exact reporting.
