The firm says that year-on-year mobile visits surged by 429% in July, coinciding with data from Ofcom that smartphones are, for the first time, the most popular way to get online in the UK.

In total 26% of visitors to the Manheim site – which relaunched in May – are now using their mobile phones. This compares to 33% of consumers who use mobile phones to go online in general.

While most users still access Manheim.co.uk from a laptop (58%), the company adds that this figure has fallen significantly from 2013, when 87% of visitors were using a laptop.

The proportion of customers using mobile devices to access Manheim’s website grew from 5% in 2013 to 8% in 2014, and has leapt to 26% in 2015.

David Flesher, head of digital marketing at Manheim, said: “We completely transformed our mobile experience, moving from a dedicated mobile website to a single, responsive design. More customers are accessing the website on mobile, and are actually visiting more as a result. 

“Much of the growth in mobile has undoubtedly been driven by consumers, and in particular social media, news and retail, but our figures show that having a mobile-first approach is just as important to B2B businesses and we continue to develop our experience to support this growing trend.”
