Lettingweb.com is the UK's most popular letting only property portal, by letting agents, for letting agents. Lettingweb’s mobile traffic currently makes up 27% of their overall web traffic and was not being optimised for these users.
Before using 51Degrees, Degree 53 was using another device detection solution. The incumbent solution did not offer new users on Android the correct content. This resulted in loss of vital revenue.
FocusVision recognised early the importance of device detection. In mid 2014 concerns over the incumbent's accuracy, performance and commercials led to the selection of 51Degrees.
51Degrees' device detection helps The Agency for Digitisation get accurate and up-to-date device information whilst saving time and tax payers' money.
