In the latest of Affiliate Window’s quarterly roundups, it revealed that 31% of all traffic on its performance marketing network came from mobile in the first quarter of this year.

While the increase from Q4 2013 to Q1 2014 was only a whisker over 1%, bigger gains were made across the whole year. Since Q1 2013 Affiliate Window has witnessed growth of 23%, which it says was fuelled by a strong January.

The two main mobile device types each take an almost even share of the network’s traffic. Smartphone’s 15% is marginally more than the tablet’s 13% for the most recent quarter.

‘Impressive’ rises

Affiliate Window stated how impressed it was to see mobile-originating transactions rise from 25% in Q4 2013 to 27% in Q1 this year, given that last year’s Christmas was roundly regarded as a mobile Christmas.

The usual retail slowdown often attributed to January resulted in just 26% of sales coming through a mobile device on the network. Although there was a small improvement in February and March as sales rose to 27% and 28% respectively.

Unlike with mobile traffic, there was a bigger difference between device types when it came to sales in Q1 2014. Tablets notched up 18%, but smartphones could only manage 9%
