What Is SEMrush?
Developed by Semrush, the platform is built around one of the largest keyword and domain databases in the industry. Where many tools focus on one discipline, SEMrush spans the whole marketing funnel, from keyword discovery to ad research and social scheduling, which is why it is a common choice for in-house teams and agencies that want a single source of truth.
Keyword Magic Tool
The Keyword Magic Tool generates thousands of keyword ideas from a single seed term, with search volume, keyword difficulty, search intent, SERP features, and question-based groupings. It is one of the fastest ways to build a topic map, and it pairs well with our guides on how to do keyword research and keyword clustering.

Site Audit
The Site Audit tool crawls your website for technical SEO issues, including broken links, duplicate content, missing meta tags, crawl errors, slow pages, and mobile usability problems, and scores overall site health. Our guide on how to fix technical SEO issues walks through resolving what the audit finds.
Competitive Research
SEMrush excels at competitor analysis. Domain Overview, Organic Research, Keyword Gap, and Backlink Gap show a rival’s rankings, traffic, top pages, paid ads, and link sources so you can uncover opportunities they are winning and you are missing. Our guide to competitor keyword analysis covers the process step by step.
Backlink Analytics and Link Building
Backlink Analytics evaluates referring domains, anchor text, new and lost links, and toxicity, while the Link Building Tool manages outreach prospects and tracks responses. To build on that data, see how to earn backlinks organically and our link building outreach templates.
Content Marketing Toolkit
The content toolkit includes Topic Research, the SEO Content Template, the SEO Writing Assistant, and content audit features that help writers produce search-friendly articles. Combined with our on-page SEO best practices, it gives content teams a complete optimization workflow.
Position Tracking
Position Tracking monitors daily keyword rankings across desktop and mobile, with local tracking, SERP feature visibility, and competitor movement, making it easy to measure campaign results. Our explainer on how Google core updates affect rankings shows why regular tracking matters. SEMrush also integrates with Google Analytics and Google Search Console for unified reporting.
