eMarketer dropped a quick and big one on us recently. It looks as though Yahoo!’s ad share is dwindling. More specifically of the $12.37 billion US paid search marketing, Yahoo!’s pie fell to 10.4% in 2010 which is down from 13.7% in 2009. That’s not all, we’re looking at single digits now, according to the post, Yahoo!’s share of overall US search ad revenues is expected to fall another 8.1% in 2011. No detail or methodology was provided.
The release of eMarketer’s report came on the heels of Yahoo! Search Direct, supposedly to compete with Google Instant Search.
The eMarketer blog post didn’t go into much detail. Here’s their hypothesis:
Much of the decline in Yahoo!’s search business is a result of Bing’s rise. eMarketer estimates Microsoft’s share of overall US search ad revenues increased to 10.2% last year — just shy of Yahoo!’s.
