our data

Our data is our most important asset and what we're most proud of. The quality of every search on SimilarWeb relies on our capacity to gather and process huge amounts of information from monitoring detailed internet behavior across the web. Over the past four years we have distributed tens of millions of different browsers plug-ins and apps, creating one of the biggest panels in the world for web measurement and competitive intelligence.

The website traffic insights that SimilarWeb provides for any website are the result of our ability to collect, understand and process vast amounts of data. Our data comes from real user interaction and not cookies, which allows us to measure the real numbers of unique visitors to a site.

size matters

When it comes to data, the bigger the panel size, the more statistically accurate the insights will be. We have panel data for tens of millions of users across the World, making our panel one of the biggest in the industry.

We implement Big Data technologies on our data center consisting of dozens of high-end servers that analyze tens of terabytes of data every week and more than 1B data points every day. The volume of data we manage and process makes our insights accurate and reliable.

Diverse Sources

We have more than hundred of different sources of data, which helps us assess and compare the quality of the data and clear biases. We combine the clickstream data from our huge panel with additional data from our crawler, which crawls over 1B pages every month, to get an even better snapshot of web activity.

Unlike some providers who focus on a specific region or user type, our collection is done on a global scale, with a statistically representative cross-section of all types of consumers. This allows us to reach unbiased, all-round understanding of a website's traffic.

Data Treatment

Once we have collected volumes of raw data, we use statistical analysis and machine learning techniques to turn it into actionable knowledge.

Our raw data is treated with in-house algorithms to remove biases, filter out noisy information and transform our data coming from different sources into meaningful insights. The data from our diversified sources is intelligently combined, normalized, and projected to represent the entire internet population.


Our expertise is web traffic, marketing analytics and internet behavior is what brings our data to live. We ensure our selection of insights from the processed data is then presented to our users in a clear format that allows you to quickly find the insights needed. We work hard so you don't have to. Instead of being overloaded with irrelevant data, we give users a focused access to the most relevant intelligence to help them with faster and better research.
