Report: Yahoo Increasing First-Page Advertisers by Chris Trayhorn, Publisher of mThink Blue Book, April 8, 2009 The keyword-tool provider AdGooroo this week released their Q1 2009 Search Engine Advertising Update which is based on an analysis of the number of ads served per keyword on each of the major search engines. There are a number of interesting findings in the report, notably: that there was a significant increase in the number of ads per keyword but a drop in the number of first-page advertisers – this may point to the search engines artificially increasing the number of ads in some way to make up for decreases in advertising activity; Yahoo increased their active advertisers by 10% and advertiser share by 4%, seemingly at the expense of Microsoft; Bank of America and resellers of used cars are advertising big right now.
