AllFacebook is reporting that Facebook is testing the placement of separate web search field at the top of the site. Facebook currently uses Microsoft's Bing search engine on the social networking site.
While it's not known whether or not Facebook will make this a permanent shift, it's substantial that the company would even consider having a second search box at the top of the site which sees over 250 million daily visitors. But if the company adds web search box at the top of their pages it could certainlly give Bing a windfall of searches soon.
"Given that Facebook is looking to ramp up their revenue as they near an IPO, a dramatic search deal between Facebook and Microsoft would not be out of the question."
No doubt Bing would pay a serious amount of money for access to the 500 million plus members' search queries when using Facebook. It is this type of deal that would dramatically increase Bing's market share of search.
A Facebook spokesperson just sent us this statement via email saying that this isn't a Facebook test and is likely caused by some third-party action or tool:
We're not testing the placement of a separate web search field and have no plans to do so. We believe the second search field or "Search the Web" box appeared on peoples' accounts as the result of unknown actions by a third party targeting the browser (potentially a browser plugin or malware) unrelated to Facebook.
If people think their browser may have been affected by malware, we offer a remediation process which includes a free browser-based virus scanning tool built by McAfee. Users are required to run this Scan and Repair tool and clean their machines of malware before accessing their account.
