The following is an example. Basically, referrals are segmented by redirected sites; redirected social media sites segment social traffic, and so on. Use display ads. This feature is handy for understanding the appearance of ads.

Combined with audience analysis (which I will discuss below), you will learn more about your various interests and how to benefit from them through advertising. On the left side of this page, you can browse any of the different traffic sources to get more information about them.

These powerful competitor analysis tools will help you understand your competitors, audiences, traffic and their bottom line to give you a real advantage.

Data Reliability.

At Seperia, we compare SimilarWeb data for accounts with actual traffic data through Google Analytics to infer its accuracy. Based on our testing, it appears that SimilarWeb’s data estimates tend to be more accurate for websites with more than 50,000 visits per year.

For websites with fewer than 50,000 monthly visits and complex websites with multiple subdomains, we found a larger discrepancy between the traffic reports from SimilarWeb and Google Analytics. In most cases, the SimilarWeb estimate was higher than the actual traffic measured by Google Analytics. On the other hand, our tests have also shown that SimilarWeb’s estimate of traffic distribution between different sources tends to be accurate.
