US paid search advertisers saw a 21% year-over-year increase in impressions and a 20% increase in click volume in Q3, according to [download page] a new report from Marin Software. Click-through rates (CTRs) were stable, while costs-per-click (CPC) continued to drop, down 14% to $0.82. But, not all verticals tracked followed this pattern. In fact, CTRs for each of the isolated verticals – auto, B2B, education, finance, healthcare, retail, and travel – all dropped on a year-over-year basis, with most of those verticals seeing increased CPCs. Among those verticals, travel saw the highest average CTR, of 2.8%, ahead of retail (2.49%) and healthcare (2.31%), while education (0.91%) had the lowest average CTR. Education had by far the highest average CPC ($5.15), more than 10 times that of retail ($0.35).
A separate report [download page] from RKG Digital finds that among its clients (that include 30 of the top 500 internet retailers), non-brand (competitive) paid search CPCs fell by 5% year-over-year, while brand term CPCs increased by 10%.
CTRs Far Higher on Smartphones
The Marin Software indicates that in the US, smartphones (11%) and tablets (8%) collectively accounted for almost 1 in 5 clicks, outdoing their combined 14% share of spend (which was split equally between smartphones and tablets). During Q3, CTRs were highest on smartphones (4.93%), ahead of tablets (3.3%) and computers (2.26%). CPCs were highest on computers ($0.77), slightly more expensive than on tablets ($0.65), and far ahead of smartphones ($0.49). The CTR and CPC results are consistent with Q2 findings.
