Google’s +1 Has Arrived — Here’s How To Add It To Your Blog
The One Technology Google Is Holding Back
Google has bought PostRank, a small Canadian company that helps companies figure out how far social messages like tweets and Facebook updates spread across the Web.
PostRank has a couple dozen employees, reports TechCrunch, and all of them are moving from Waterloo, Ontario — home of Research in Motion — to Google’s Mountain View headquarters.
The companies won’t say what PostRank is working on, but it could fit into Google’s new +1 social projects, or perhaps be rolled into some of Google’s tools for advertisers.
Google has been snapping up small companies left and right: last week it bought Seattle startup Sparkbuy, which made a search engine to help gadget freaks shop for computers and electronics gear online, and in April it bought mobile music company PushLife, which, like PostRank, is also based in Ontario.
