Key Features Breakdown
1. Keyword Research
Semrush’s Keyword Magic Tool is the best keyword research tool we’ve used. Enter any seed keyword and it returns thousands of related terms with search volume, keyword difficulty scores, SERP features, CPC data, and trend history. The Keyword Gap tool lets you compare your keyword profile against up to 5 competitors simultaneously.
2. Site Audit
The technical SEO audit crawls your entire site and identifies issues grouped by severity — errors, warnings, and notices. It checks over 140 technical factors including page speed, broken links, duplicate content, missing meta tags, Core Web Vitals, and HTTPS issues.
3. Competitor Analysis
This is where Semrush truly separates itself. Enter any competitor’s domain and instantly see their top organic keywords, estimated monthly traffic, paid ad campaigns, backlink profile, and top-performing content. The Traffic Analytics tool estimates real visitor numbers — remarkably accurate in our testing.
4. Content Marketing Toolkit
The Content Marketing Platform (Guru and above) includes Topic Research, an SEO Writing Assistant, Content Audit, and Post Tracking. The SEO Writing Assistant integrates directly with Google Docs and WordPress, giving you real-time optimization suggestions as you write.

Semrush’s backlink database is one of the three largest in the industry. The Backlink Audit tool identifies toxic links dragging down your rankings, while the Link Building Tool manages outreach campaigns.
