These help you plan, write, and score SEO-friendly content from inside the platform. If content creation is central to your digital strategy, this toolkit sets Semrush apart from Semrush alternatives like Similarweb.

6. Rank Tracking and Position Monitoring
Semrush： Position tracking monitors target keywords daily across desktop and mobile. The Pro plan tracks 500 keywords. You can set up local tracking for specific cities and compare rankings against competitors on the same dashboard.
Similarweb： The rank tracker monitors keyword rankings and search engine positions. It’s available on the SEO-tier plans. While functional, Similarweb’s rank tracking focuses less on daily granularity and more on understanding broader keyword performance trends.
7. Market Research and Traffic Analysis
Semrush： Market research is available as an add-on called Traffic & Market Trends at $289/month. It’s not included in any standard plan. The organic traffic insights tool shows estimated traffic for your own site but doesn’t estimate competitor total traffic the way Similarweb does.

What Our Review Didn’t Cover
This comparison focused on individual marketers and small teams. We didn’t test enterprise SSO, custom API integrations, or bulk user management features. Similarweb’s Sales Intelligence and Shopper Intelligence modules weren’t part of this review. Semrush’s new Semrush One bundle with AI Visibility tracking wasn’t evaluated in detail.
