Search Engine Advertiser Update – Q408
January 12, 2009
December’s data continues to support our thesis that Q4 will prove to be the strongest quarter on record for Google and Microsoft Live Search.
Google led in Q4 with first-page advertiser growth of 58.0%, followed by Live Search with 42.3%. Yahoo trailed with a mere 8.8%, surprisingly low given the brisk pace of online holiday sales.
Microsoft continued to close the gap in advertiser share with Yahoo. In Q3, Yahoo led by 17.6 percent (30.4% vs. 12.0%). By the end of Q4, this lead has narrowed to 3.0% (19.4% vs. 16.4%).
As we reported in our mid-quarter update, we measured large increases in ad coverage on Google - a trend which continued throughout December. Yahoo remained consistent with previous 2008 ad coverage measurements, while Microsoft ad coverage declined in Q4 (indicative of continuing focus on ad quality control and holistic search).
We expect a flattening out or even a decline of advertiser accounts into Q1. This is typical of the post-holiday quarter, but should nevertheless lead to positive Y/Y growth.
