In the opinion of search market experts speaking at the Search Marketing Expo in Seattle on Monday, with the Yahoo and Microsoft Bing integration in place, search marketers may begin optimizing their sites for Bing.

Thus far, the search marketers have been optimizing their sites only for Google, ever since the search engine’s dominance of the market.

With the present search-market-share statistics revealing that Bing’s search market share will increase manifold once its search technology begins generating results for Yahoo, search engine expert Danny Sullivan – who is the editor of the Search Engine Land blog – said: “Now we're in a situation where we're going to have Bing powering up to 30 percent of the market.”

Noting that some similar basic optimization techniques will work for Google as well as Bing, Janet Driscoll Miller, president and CEO of SearchMojo, said at the event that, Bing also provides the search marketers a few new opportunities – including a preview box pop-up; an H1 tag; and buttons for sharing some search results on Facebook, Twitter or via e-mail.

Adding that, in the future, search market will witness a two-engine world, featuring both Google as Bing as search engine optimizers (SEOs), Miller said that it is only after the Yahoo-Bing integration takes place that search marketers may consider whether will be worth optimizing their sites for Bing, because at present they cannot get enough traffic from Bing!
