Our Data
  1. 1. Where does SimilarWeb get the data from?

    Our data come from combination of our powerful crawler and click-stream data from our proprietary panel of tens of millions of users who have installed our apps.
    We always try to make sure that our panel will be big and diversified.

    Our panel is several times bigger than traditional panels. This allows us to learn about every website, big and small, and overcome the statistical errors that are typical of smaller panels.

    We implement Big Data technology on our data center consisting of dozens of high-end servers to analyze the resulting tens of terabytes of data. Once we have collected volumes of raw data, we use statistical analysis and machine learning techniques to generate actionable knowledge. Our data is taken from diversified sources, then intelligently combined, normalized, and extrapolated upon to represent the entire internet population. Our data is analyzed continuously and aggregated on demand so we can immediately deliver accurate traffic details on every website.

  2. 2. How many URLs do you have in your database?

    We currently have over 50 million domains in our database, which is constantly growing and continuously updated.

  3. 3.How do you calculate website ranking?

    Our ranking is calculated with a unique algorithm that takes into account a combination of website engagement metrics, including the number of unique visitors to a site and the number of page views. The size and breadth of our global panel of users enables us to assess how a website ranks in the entire internet, on individual countries and on its category.

  4. 4. How often is the API data updated?

    Our APIs are being updated on a monthly basis.
