Mobile devices account for twenty-four.5 per cent of total paid search spend and 27.8 per cent of total clicks inside the UK, in line with a report from Kenshoo.

While smartphones account for 11.5 per cent of search clicks, they simply make up 7.8 per cent of spend. It is a similar story within the US, where smartphones account for a slightly lower nine per cent of clicks – but, crucially, for just five per cent of ad spend.

 Tablets fare a lot better in both markets. As a matter of fact, their share of ad spend (16.7 per cent) narrowly exceeds that of search clicks (16.3 per cent) inside the UK. Within the US, tablets account for 10 per cent of clicks, and nine per cent of spend.

“Advertisers must be assessing the worth of mobile clicks in other ways, since you can’t expect a phone to deliver an analogous rate of direct online sales as devices with bigger screens which can be typically utilized in the house,” said Kenshoo CMO Aaron Goldman. “It’s imperative to trace and optimise conversion events like phone calls, app downloads, check-ins, website registrations, store locators. These are KPIs we should always be using to measure the effectiveness of phone clicks.”

Meanwhile, CPC (Cost Per Click) at the devices has risen to £0.20 for phones and £0.30 for tablets – the latter equal to the worth on PC.
