What Is Semrush?
Semrush is a web-based marketing platform split into toolkits: SEO, AI Visibility, Content, Local, Traffic & Market, Social, Advertising and AI PR, plus an App Center and an API. The SEO + AI Search plans (SEO, Starter, Pro+ and Advanced) pair keyword and competitor research, Position Tracking, backlink analysis and Site Audit with the AI Visibility toolkit. Its Prompt Tracking report follows chosen prompts in ChatGPT Search, Google AI Mode and Gemini and shows brand mentions, average position and every URL the AI answers cite. Higher tiers add historical SEO data, keyword cannibalization analysis, multi-location and device tracking, SEO share of voice and API data integration, and MCP access starts at Starter. Reports connect to Google Analytics and Google Search Console, while report add-ons handle scheduling, PDF export and white-labeling. A free account includes one demo project and ten reports a day. An Enterprise edition adds SSO, audit logs and crawling for sites with millions of pages.
Best for: SEO teams and agencies that want keyword research, rank tracking, audits and AI answer monitoring in one subscription.
Semrush separates research databases from project-based monitoring: a competitor domain can be explored without ownership, while Site Audit and Position Tracking are configured for an individual project. Keyword Gap compares ranking footprints across domains, and backlink tools identify referring-source patterns. Search estimates and first-party conversions remain different datasets that need separate interpretation.
