Start Free Trial →SEMrush is an all-in-one digital marketing platform best known for its SEO capabilities. Founded in 2008, it now covers SEO, PPC advertising, content marketing, social media, and competitive intelligence — all in one dashboard.
The key differentiator: SEMrush has the largest third-party keyword database in the world (25+ billion keywords across 142 countries) and tracks 43 trillion backlinks. No other tool comes close on data volume.
The Keyword Magic Tool gives you access to 25B+ keywords with metrics like search volume, keyword difficulty, CPC, and SERP features. The AI-powered keyword clustering groups related terms automatically — saving hours of manual work. In our test, we built a full content strategy for a new niche site in under 2 hours.
Type any competitor's domain and see their top organic keywords, traffic estimates, best-performing pages, backlink sources, and ad spend. This is SEMrush's strongest feature — we've used it to identify keyword gaps that generated 40%+ traffic increases for client sites.
SEMrush's site audit checks 140+ SEO factors and gives you a health score with prioritized fixes. The AI explains each issue in plain English and tells you exactly how to fix it. Runs on schedule automatically — you'll always know your site's SEO health.
Built directly into the platform, the SEO Writing Assistant scores your content in real-time for readability, tone, and SEO optimization. It shows what semantically related terms to include and checks plagiarism. Solid, not the best standalone writer — but perfectly integrated.
