Greg Sterling gives it a thumbs up. I think his assessment, even though I haven’t used it myself, is pretty solid.
If I search on something that isn’t within the scope of Graph Search (e.g., plumbers) I’ll get Bing results. This is significant because people are going to start searching on anything and everything to see what happens and what comes up. It avoids the “no results” problem that might have undermined getting users to “come back” to Graph Search.
I’ll have to agree. The worst thing in the world for Facebook would be for users to get a bunch of “no results” results and stop using the feature.
Bing could very well increase its share of the search market if the Graph Search catches on, but I doubt that it will be a big leap. Even a 1% or 2% increase would be something. And if Greg Sterling is right that people will use Graph Search more broadly than Facebook intended, that will bode well for Facebook as well. You may very well see people using Facebook more than Google if they find positive results – at least with certain verticals like restaurant recommendations.
The main thing is competition. If there’s enough of it, then search will improve all around. For businesses, it means another way to be found by your target audience.
