If Facebook users type in a string, such as "Find restaurants where my friends eat in London", they'll be presented with a list of places their connections have recently checked-in at and recommended.
A similar search on Google would generate a list of London restaurants, but unless they've eaten there before or heard good things from a friend or colleague users will be flying blind.
Given the value people place in the recommendations of friends, users may over time become more inclined to rely on a Facebook search to find things to do than a Google one. Especially if it means they don't have to leave the site.
This could be a troubling development for Google, which has been striving to provide users of its Google+ social networking site with a more personalised web search experience for some time.
What Google has in its favour is that it already has the information (and possibly the algorithms) needed to deliver this, but the Google+ user base is nowhere near as large as Facebook's.
One way Google could make Graph Search work for it is by teaming up with Facebook in the same way Microsoft has. This is an idea Zuckerberg has entertained, but he suggested the firm couldn't agree on privacy terms with the web giant.
"I'd love to work with Google...[because] we want to make search social [and more open] in general," he added.
What it means for Microsoft
According to data from internet market analyst NetMarketShare, Google currently holds more than 83 per cent of the global search engine market for desktop devices. Yahoo is in second place with a shade over 8 per cent, while Bing is third with 4.6 per cent. I'd love to work with Google.On top of this, a report on US news site Daily Caller recently claimed that Microsoft is losing $2billion a year on Bing. The Facebook connection could help the firm staunch some of these losses by sending more traffic Bing's way.
This all largely depends on how long the Facebook-Microsoft partnership is forecast to last for and if the site never does manage to resolve its apparent privacy issues with Google.
At last night's event, it wasn't made explicitly clear if Facebook plans to make Bing a permanent part of its search service or rely on it to plug the gaps until it has the data needed to do that itself.
If it is a relatively short-term thing, it certainly won't do the Bing brand any harm to be closely associated with the world's largest social networking site. It could also provide it with a stay of execution, because there's only so long any company can afford to support a business that's supposedly not making much money.
If Facebook is planning to make Bing a permanent fixture (and users take to Graph Search in the way Zuckerberg obviously hopes they will), this could be very good news for the search engine and, at the very least, help it make a dent in Yahoo's market share.
As for Google, the internet giant is unlikely to roll over and let Facebook encroach too much on its territory, and the site will undoubtedly remain the default search choice for most web users for a long time to come.
What will be interesting to see is, if Google does lose some share to this Facebook-Bing venture, if this might prompt the firm to come round to the social networking site's way of thinking on privacy.Continues over page...
