Since Microsoft relaunched its Bing engine last year, audience measurement firms Nielsen and comScore have reported increases in consumer use of the product. However, the companies’ estimates for Bing’s overall search market share in August differed substantially, throwing into question how much progress the engine has actually made.
According to Nielsen, Bing’s market share grew by two percentage points during August, reaching an overall share of 13.9 percent, while Yahoo’s properties accounted for 13.1 percent of U.S. searches, Nielsen said. Meanwhile, comScore’s market share data for August tells a different story, attributing Bing with just 11.1 percent of searches, and Yahoo with a 17.4 percent share.
Interestingly, however, the firms agreed one way or another that Microsoft and Yahoo’s combined “search alliance” market share stood at around 28 percent. As part of that arrangement Bing will soon power all search results and advertising on Yahoo’s search properties, but the two search entities will still compete for audience, with Yahoo’s reimbursement based on the number of searches it attracts.
