SEO, competitive, and AI visibility research in one marketing platform.

Semrush is a web-based marketing intelligence suite for researching keywords, competitors, backlinks, traffic, ads, local visibility, social activity, and content opportunities. It also adds tools for tracking how brands appear in AI-generated answers and for bringing Semrush data into AI-assisted workflows.

Why it stands out

  • Combines traditional SEO research with newer AI-search visibility tracking rather than treating them as separate products.
  • Large stated datasets, including billions of keywords, trillions of backlinks, hundreds of millions of domain profiles, and many geo databases.
  • Covers adjacent marketing channels such as paid ads, local listings, social, PR, and content, making it broader than a keyword-only SEO tool.
  • Enterprise and API options support larger teams that need reporting, integrations, or programmatic access to Semrush data.
  • Includes free standalone tools alongside the paid platform, useful for quick checks before committing to a workflow.

Good to know

  • Full platform use appears to require a paid plan or trial; the page promotes free tools but not unlimited free access.
  • Its metrics are third-party estimates and visibility signals, so they should be validated against first-party analytics and ad-platform data.
  • AI visibility reporting depends on monitored prompts and supported AI platforms, so it may not cover every query or model a brand cares about.
  • The site notes that outdated browsers or operating systems may not display Semrush correctly.

Under the radar: Before building a full AI visibility workflow, check the AI Visibility Index to see which brands are already being mentioned in AI answers and use those names as competitors to monitor.
