Semrush Key Features
Keyword Research
Semrush's Keyword Magic Tool has the largest keyword database in the industry — over 25 billion keywords across 142 countries. Type in any seed keyword and instantly see search volume, keyword difficulty, CPC, trend data, questions, related terms, and SERP features. For small businesses targeting local or niche keywords, this data is invaluable for finding low-competition, high-intent opportunities.
Competitor Analysis
Enter any competitor's domain and see every keyword they rank for, their top pages, where their traffic comes from, their paid ad keywords, and their backlink profile. This is Semrush's killer feature — it turns competitor research from a guessing game into a data-driven strategy.
Site Audit
Semrush's site audit crawls your entire website and flags technical SEO issues: broken links, missing meta tags, duplicate content, slow pages, missing schema markup, and over 130 other checks. It prioritizes issues by impact so you know what to fix first.
Position Tracking
Track your keyword rankings daily across Google and Bing, in any location (country, state, city, or zip code). Essential for local businesses wanting to rank in their city and for agencies reporting ranking progress to clients.
Backlink Analysis
Semrush has the second-largest backlink index after Ahrefs. Analyze your own backlinks, monitor new and lost links, identify toxic links that could hurt your rankings, and find link-building opportunities by seeing who links to your competitors.
Content Marketing Toolkit
Semrush's content tools include topic research (find what angles to cover), the SEO Writing Assistant (real-time content scoring), and a post tracking tool that monitors how individual articles perform in search over time.
