The cost per click (CPC) rose 10% during the quarter and 24% year-on-year, driven by market and platform changes, for Covario's clients. The effectiveness of ads, measured through the click-through rates (CTRs), produced 27% better results compared with the same quarter a year ago.
Regionally, marketers in the Americas spent 8% more sequentially, and 17% compared with the year-ago quarter. In EMEA, major gains helped the region regain pace after a slow 2012, with 43% quarter-on-quarter and 73% year-on-year improvements. In Asia-Pacific, growth topped 55%, compared with slower sequential gains, but fell 1% compared with the same quarter a year ago.
As for Covario's clients, Google continues to dominate globally with 86% market share for budgets, 86% in impressions, and 62% in clicks. Advertisers spent 13% more with Google compared with the year-ago quarter.
Covario's clients also spent more for paid search on mobile devices. In fact, globally, they spent 39% more sequentially, and 132% compared with the year-ago quarter.

At The Rimm-Kaufman Group, tablets and smartphones drove 28% of paid clicks, taking 22% of marketers' budgets. With desktop and laptop clicks down 7% year-over-year, 178% growth for smartphones and 115% growth for tablets drove up clicks by 12%.
Smartphone CPCs rose from 55% of desktop to 60%, as more advertisers transitioned to Google Enhanced Campaigns. The impact to total CPC growth was negligible.
RKG said Bing Ads search costs rose 58% in Q2, compared with the year-ago quarter, the third quarter in a row where its growth rate more than doubled that of Google. Bing's growth has been driven by a surge in non-brand clicks, which rose 49%, as ROI remained stable.
