similarweb and semrush different data
Get quality insights about your users, from your users
Similarweb’s digital insights are powered by real user searches and real user behaviors – that means accurate search data, search volume, and search intent. Semrush, on the other hand, bases its traffic estimations largely on rank, when rank is not equal to traffic.

Spot trends when they’re actually trending
Similarweb is the only tool to offer a ‘Last 28 days’ view so you are able to track trends in real-time – as they happen. That means no waiting around for monthly updates like Semrush users, when the trend has already gained competition for SEOs (and got expensive for PPC).
