Methodology

When interpreting our surveys, you should know the following:

• We include only relevant websites in our surveys. A website is relevant if it has some meaningful content or functionality. We use content analysis as well as the linking structure among websites to determine the relevance of a site. Our sample consists of the many millions of websites, that we call the relevant web.
• We exclude sites that have no useful content, e.g. sites that only show the default web server page. We also exclude sites that are essentially duplicates of other sites.
• We use ranking data provided by Google in the Chrome User Experience Report (CrUX) as well as a customized version of the Tranco list for our ranking-related reports, e.g. usage of technologies by the top 1000 websites. Before November 2022, we used the Alexa ranking for that purpose.
• We investigate technologies of websites, not of individual web pages. If we find a technology on any of the pages, it is considered to be used by the website.
• We do not consider subdomains to be separate websites. For instance, sub1.example.com and sub2.example.com are considered to belong to the same site as example.com. That means for example, that all the subdomains of wix.com, wordpress.com and similar sites are counted only as one website.
• We use the official part of the Public Suffix List to determine what exactly is a website and what is only a subdomain.
• We do not include redirected domains. For example, Sun.com redirects to Oracle.com, and is therefore not counted.
• Our reports are updated daily.
• Please be aware of the limitations indicated in our disclaimer.
