AllFacebook is reporting that Facebook is now displaying some ‘outside’ webpages with in its Facebook search results.  For instance, if you Search for the Annapolis Marriott hotel in Facebook, one of the results is the TripAdvisor page which has been favorited by five ‘Facebookers.’

To make matters worse for Google (GOOG), Facebook uses Microsoft’s (MSFT) Bing Search to place Web results at the bottom of the Facebook search results.

Also, it appears that Facebook is only including results with special codes embedded into the Web Page, which Trip Advisor has included.  That doesn’t mean Facebook won’t be crawling the greater web, for results.

Will Facebook’s Semantic Search Engine, which uses user popularity as a measure of website quality and keyword relevance be enough to best Google? Will “link baiting” give rise to “like baiting”?

Facebook ‘likes’ could become the new PageRank if Facebook search becomes more popular.  That could also mean an army of offshore faux Facebook users liking Viagra pages.

If this kind of search becomes useful and therefore more utilized, is Google’s search dominance in jeopardy?   Facebook does have some mind-bendingly huge numbers of users and growth.  It remains to be seen how much better this feature becomes.

If Facebook’s search can garner better results than Google, then there is some trouble ahead for Mountain View.
