Limitations of SimilarWeb’s data

SimilarWeb is a web analytics company that provides website popularity and traffic data. However, the company’s data has several limitations. First, SimilarWeb only collects data from websites that have installed its tracking code. This means that the data is not representative of the entire internet. Second, the information is not always accurate.

For example, in 2016, SimilarWeb reported that Facebook was the second most popular website globally. However, later that year, Facebook announced that it had reached 2 billion active users, which was not reflected in SimilarWeb’s data. Finally, SimilarWeb’s data is not always up-to-date. For example, as of January 2017, YouTube was still listed as the third most popular website in the world even though it had been surpassed by Facebook in terms of traffic a year earlier.

How SimilarWeb gathers data and how it is used.


Similarweb is a website that gathers data about websites. It collects information about how many people visit a website, where its visitors are, and what websites people see after they leave the first website.

This information is useful for organizations because it helps them understand how popular their websites are and how they can improve their website’s design or content to keep people visiting.

5 Methods of how Similarweb Gets Its Data:

SimilarWeb is a leading website analysis and insights company that gathers data from millions of websites worldwide. They use various methods to collect website data, including crawling, scraping, and data extraction. SimilarWeb then uses its proprietary algorithms to analyze this data to generate insights about the websites that matter most.


1. Crawlers

In the world of web development, there are two main types of crawlers: the bots that search engines use to index websites and the bots that hackers use to scan websites for vulnerabilities. While their purposes are different, both types of crawlers share some common characteristics. They are both automated programs that run continuously, and they can both be customized to fit the user’s specific needs.

Similarweb uses crawlers to gather data from websites. The most common type of crawler is a spider. These spiders crawl websites by following links from one page to another. The spider works because it visits all the pages on a website and records the content for later analysis.

2. APIs

In computing, an application programming interface (API) is a set of rules and procedures that allow software components to communicate with each other. APIs can be used to provide access to internal data or functionality or extend an application’s reach into new areas.

Many popular online services and applications rely on APIs to function.APIs can be a powerful tool for businesses and developers alike. By providing access to internal data or functionality, they can enable third-party developers to create innovative new applications that benefit both the developer and the service provider. Similarweb also gathers data through APIs.

3. User Contributions

Google Maps relies on users to submit location data. The websites use algorithms to determine which contributions are most valuable and reliable in both cases. Users can contribute data to Similarweb through its website.

4. Partnerships

Similarweb has a long history of partnering with third-party developers. For example, Similarweb is currently partnered with New Relic to measure the application performance of mobile applications. Similarweb also has partnerships with companies like Google and Twitter to gather data on their websites. It has partnerships with other companies that help it collect data.

5. Other Methods

Similarweb uses direct application integration to collect data from mobile apps, similar to how Google and Facebook gather data on their websites. It also contains information by offering services like the mobile app store and the SDK. It uses many other methods to gather data as well.
