Many websites have been adapted for access by smartphones and tablets. This has required web archivists to change the way they archive this ephemeral web content. A tool has been created using Heretrix called MobileFinder which can be used to automatically detect mobile pages when given a seed URL. It can be used as a web service.
There are three primary techniques used by websites to deliver mobile pages, and the results of a test to determine which technique was used:
- Using responsive web design techniques to deliver the same content to both desktop and mobile devices: 68%
- Dynamically serving different HTML and CSS to mobile devices using the same URL: 24%
- Using different URLs to send out desktop or mobile pages: 8%
