- A few of the Alexa top 100 sites are not sites designed to be browsed as such e.g. googleusercontent.com and t.co (Twitter’s URL shortener).
- The main entry point for the Wikipedia does not use device detection but all of the language-specific entry points do e.g en.wikipedia.org and es.wikipedia.org etc. For this reason I counted this as a site that uses adaptation since search results usually send you to the language-specific entry point.
- A bug in the library that I was using to crawl the sites caused failures for a handful of them so I checked these by hand.
- This method of counting server-side device detection probably under-counts if anything since some sites may use server-side image resizing as a means of adaptation without changing the containing HTML document.
- Sites can use device detection simply to redirect browsers to a more mobile-friendly site and/or adapt the HTML to the particular device in question.
