Semrush vs Similarweb Comparison: Which Tool is Better?


With the release of Semrush .Trends – a repackaged version of the suite’s market and competitive research tools – we’ve decided to revisit the good old Semrush vs Similarweb discussion.

If you’re looking for a market and competitive intelligence tool that would uncover all you need to know before entering a new market, thinking of a business expansion, or when you simply need to stay on top of emerging trends and competition, you will probably end up choosing between Semrush and Similarweb.

Feature Comparison

Now, the most important decision-makers are features available or absent across the tools. Let’s see which solution offers the fullest market and competitive data coverage across the board.

Mobile data

Having access to mobile data is crucial, especially now when we live in the world of mobile-first and when 66% of all site visits come from mobile devices.

Whatever plan you’re on, Semrush gives access to mobile data to all users.

Conversely, Similarweb’s mobile data comes at a separate price and you have to purchase mobile databases on top of everything else.
