Four reasons smart marketers turn to Similarweb over Semrush

Native AI Intelligence

Stop measuring AI with an SEO yardstick

Semrush takes its existing position tracking infrastructure and maps it onto AI platforms, giving you a retrofitted top 3/10/20 score. Similarweb tracks real visibility: how often your brand shows up, and against which competitors...metrics that are native to how AI search actually works.

Data Quality

Swap unverified methodology for real user data

Semrush builds its AI metrics on top of keyword inference, estimating where your brand appears based on search position signals rather than actually looking at AI conversations. Similarweb pulls from real user interactions. That means when you see a visibility score or a mention count in Similarweb, it reflects real user behavior. Not a model built on top of a model.

Prompt Tracking

Base your content on real prompts, not keywords

Semrush tries to track prompts by layering old keyword data onto new platforms. But this 1-to-1 model doesn't work for AI because people don't talk to chatbots in keyword fragments. Similarweb captures the actual conversations users have with AI to show you the real-world intent that drives a user's next move.
