While Ahrefs and Semrush are both superb all-in-one SEO suites, there’s a reason why some top agencies use both. Though they have significant overlap, they also have some unique features defined by each tool’s original purpose.
Ahrefs began primarily as a backlinks tool, which makes sense, as Google started as a backlinks-powered search engine. Meanwhile, Semrush started as a keyword research tool, which is a tool for discovery and competitor analysis. Let’s take a deeper look into why you might prefer one of these SEO tools over the other.
What is Ahrefs?
Originally a backlink builder, Ahrefs has expanded to include keyword research, competitor analysis, link building, rank tracking and site audits. Through Ahrefs, SEO marketers get the information they need to produce better-optimized content that appears higher in search results. Throughout the industry, Ahrefs is praised for its keyword research and technical SEO tools.
What is Semrush?
Semrush is a software-as-a-service suite built for keyword research, online ranking data and marketing performance analytics. Semrush contains a wide breadth of tools including a site health checker, backlink checker, analytics system and more. Semrush is frequently used not only for technical analysis of websites and their content but throughout the search marketing discovery and research process.

Feature comparison: Ahrefs vs Semrush
Ahrefs is built for backlink analysis (Figure A). It has an easy to navigate UI and functional reporting. These two features set it apart from many of its competitors, as backlink analysis often produces large volumes of barely human-readable data. Ahrefs makes this data easy to read and accessible.
That being said, Semrush recently increased its link building data to include 43 trillion backlinks. In 2021, it performed a massive push to build the biggest backlink database in the world. Until then, Ahrefs was firmly in the lead.
While Semrush may currently have the most accurate and comprehensive backlink database, Ahrefs still has a slight edge in terms of usability. Most who use the tools for business would likely find the interface of Ahrefs more comfortable to use. On the other hand, SEO professionals, technical marketers and some data-focused users may prefer Semrush’s advantages in speed and breadth of knowledge.
In both Ahrefs and Semrush, you can perform rigorous keyword research. Type in any keyword, and Ahrefs and Semrush will return a dense list of related and long-tail keywords. These results are all scored by traffic and whether your site can potentially rank well for each keyword according to several factors.
Ahrefs provides click data in addition to search data — it estimates how many clicks you might get for a given keyword in addition to the number of searches performed. This data is extraordinarily useful to marketers when deciding whether the page you build to target that keyword is likely to produce the desired number of conversions.
Semrush doesn’t provide click data, but it does provide information for PPC campaigns (Figure B). During keyword research, you can see both the organic search results and the paid search results. This information isn’t as directly useful for purely organic campaigns, but it is helpful for search engine marketers looking to boost performance through paid search campaigns.
For many companies, rank is the most important performance metric. Where are you ranking on Google?
Both Ahrefs and Semrush are actually evenly matched in terms of accuracy, but Semrush has a slight edge because it refreshes more frequently. Ahref and Semrush’s data generally match and even out, but Semrush will give you visibility into virtually real-time changes (Figure C).
Ahrefs has an extremely compelling tool called the Content Explorer (Figure D). After you’ve selected a keyword, Ahrefs will show you all the high-performing content that targets that specific keyword. The information will include domain authority, referring domains, social media shares and meta tags.
Semrush does have a competitor analysis section, which provides key insights into what competitors are doing with their keywords. However, it isn’t as content-based as Ahrefs’, as it’s designed mostly for keyword discovery.
Technical SEO and site auditing
Both Ahrefs and Semrush have robust site auditing tools, which highlight technical SEO issues such as missing meta tags or missing pages.
Ahrefs provides visually dense information that is extremely useful but can be hard to read for those unfamiliar with technical SEO or the tool itself.
Semrush’s platform is designed to be a little more user-friendly. Reports in Semrush will both highlight technical SEO issues and suggest how to fix them. This is ideal for business users who are just learning SEO or small teams where content marketers also moonlight as the SEO pro (Figure E).
