Google Becoming More Efficient: Improved CTR

The recently reported decline in Google paid clicks caused what may be an unnecessarily strong reaction in the investment community this past week. Efficient Frontier's US Client Index, which covers more than 20 million paid clicks each month, did indeed see a 5% drop in click volume on Google when comparing January 2008 to January 2007. But same advertiser spend was up on Google by 7% in the same period, and click through rates improved by 10%. CPCs were up by 13%. This data suggests, as Comscore posited, that Google is becoming more efficient at serving ads by delivering more relevant clicks to advertisers. Thus it is able to charge a higher premium for those ads, hence the increase in CPCs.

Our Search Engine Performance Report: Q4 2007 showed that ROI on Google was up 7.5% from Q4 2006 to Q4 07, which does not spell disaster in my mind. Next week we'll take a look at overall statistics for February on this blog. Stay tuned!
