Analyzes your competitors You can research competing websites to estimate their organic traffic, discover which keywords they rank for, and identify topics your website is missing. Example: Discover that a competing bakery ranks for “gluten-free birthday cakes,” while your website doesn't have a page for it. 3.

It depends on your needs. | Semrush is useful if you… | You might not need it if you… | | --- | --- | | Want to grow website traffic | Have a very simple website | | Publish blogs or landing pages | Rarely update your site | | Need to analyze competitors | Only need basic traffic data | | Manage SEO for clients or multiple sites | Are just starting to learn SEO | One important distinction: Semrush doesn't automatically get your website to the top of Google. It provides data, insights, and recommendations; you or your SEO team still need to implement them. Its traffic and keyword metrics are estimates, not a substitute for your own analytics data.
