Device DetectionData Quality

Device detection vendors need to stay on top of the latest changes. Supported by our ISO 9001/27001 certifications, 51Degrees is the only provider that publishes weekly active and total profile metrics.

Check out the latest metrics for each component:

Browser

In the "Browser" component, we classify web browsers, WebView, popular native apps, and apps operated by our customers. Understanding the difference allows our customers to maximize revenue based on how the user is viewing the content.

We maintain 118 different properties relating to the browser. The below graph uses the IsWebApp property to populate the following categories:

  • Web Browser includes Chrome, Firefox, and Safari (to name just a few)
  • App includes applications such as Facebook, Snapchat, TikTok, or generic unnamed apps
  • Unclassified (see our explanation)

Crawlers

Web spiders, web crawlers, robots, bots – many names exist for the automated applications that crawl the Internet. By identifying bot traffic, businesses can verify that their audience is made up of real humans, not fake activity.

We have 3 crawler properties and we populated the graph below using the IsCrawler property. The categories are:

  • Crawler (definitely not a human)
  • Non-crawler (probably a human)
