Analyzing web traffic and gaining competitive insights with comprehensive data
The website analysis feature in SimilarWeb is vital for my work. It provides everything I need by allowing me to input any domain and filter by country. I can see the number of visitors over time, the number of unique users, session duration, clicks per session, and more. This helps me understand traffic patterns, user engagement metrics, and user journeys before and after visiting a site. Having this comprehensive data in one feature gives me crucial information for strategic planning. Additionally, there is a unique feature to look at outgoing traffic from ChatGPT or Perplexity, showing how much traffic certain websites receive from these tools.
