SiteSpect has replaced WURFL device detection with 51Degrees. We made this change to improve accuracy. This document includes frequently asked questions and responses about this change.
This change has no effect on pre-existing Campaigns (live, paused, archived, and so on). Any Campaign that existed before the upgrade continues to use WURFL for both assignment and reports.
All new Campaigns use 51Degrees. You don’t need to do anything; the upgrade handles the switch.
No. There are no additional new steps you have to take when using Audiences or mobile reporting segments.
Yes. These will now work and are very accurate.
Accuracy depends on specific criteria. For example, is_mobile and is_tablet will be very accurate compared to more complicated device criteria such as non-smartphones, specific screen size, etc.
We recognize how important device detection is to you and want to provide a solution that is very accurate and includes automatic updates so that our device detection remains current as new devices and browsers become available.
No, there is no way to make an existing Campaign use the new device detection. Instead, create a new Campaign or clone an existing Campaign; it will automatically use the improved device detection.
In most cases, the definitions are the same. There is a slight difference in the way screen size is evaluated for tablets. WURFL assumes that tablets are in portrait mode while 51Degrees assumes that tablets are in landscape mode so the width and height are reversed specifically for tablets. For example, if you target tablets by screen size, WURFL defines iPad as 1024x768; 51Degrees defines iPad as 768x1024.
