Do any SEOs concentrate on search engines other than Google? While many would argue that it's important, trying to optimize specifically for Yahoo or Bing doesn't seem all that worth it when you look at the numbers. According to the latest comScore report, Bing still only has around 20 percent of the search market share.
The release of Windows 10, however, has the potential to boost Bing searches similarly (but on a much larger scale) to how Mozilla's Yahoo deal boosted searches for Yahoo for a brief time. But will it be enough to get naysayers to pay attention to Bing?
