FAQ

Is SimilarWeb really free or are there hidden costs?

The core features—traffic overview, source breakdown, and basic keyword data—are completely free. Hidden costs only appear if you upgrade to the premium plan for deeper insights, API access, or extended historical data.

Can I use SimilarWeb for mobile app analysis?

Yes. SimilarWeb provides app download estimates, usage metrics, and ranking data for both iOS and Android platforms. This information appears under the “App” tab after you search for an app’s package name.
