Search Visibility Share

We combine audience intelligence data, metrics from actual advertising campaigns, and machine-learning models to produce accurate estimates of search volumes and trends. Our models use aggregated traffic data to generate these estimates and are calibrated using anonymized metrics from real advertising campaigns, provided through business agreements with some of our customers. This combination helps us ground our estimates in real-world data and improve their accuracy.

• Search volume: We estimate search volume using traffic data from third-party data providers and our proprietary algorithm.
• Traffic: Traffic is an estimate based on keyword positions, estimated search volume, and average click-through rate (CTR).
• CPC: Our CPC estimates combine data from third-party providers with metrics from actual advertising campaigns run by Semrush and our partners.

We update our databases every month. Some popular high-volume keyword data is updated weekly and even daily.

No. Semrush and web analytics tools such as Google Analytics measure traffic in fundamentally different ways. Semrush uses multiple data sources and modeling to estimate overall website traffic. This measurement is independent of the tracking technologies implemented on individual websites. Web analytics tools, on the other hand, measure activity through website-side tracking, and their coverage can vary depending on the tracking setup, consent choices, and other technical factors. For competitors whose proprietary analytics you cannot access, Semrush provides estimates measured consistently across domains, making it possible to compare traffic and performance.
