Google announced a deal to buy business analytics software vendor Looker for $2.6 billion. The acquisition will extend the capabilities of Google’s existing cloud database products by letting users create shared business metrics and develop applications. Looker will continue to run on all cloud database platforms.

Nothing is murkier than influencer marketing. Klear, an influencer marketing platform, says it can fix this with a newly-announced feature to estimate campaign ROI by calculating Earned Media Value – that is, the how much it would cost to buy the same amount of coverage in paid media (a.k.a. advertising).

A U.S. district court judge has ruled that Google acted to create illegal monopolies in online advertising technology in a way that blocked competition and allowed higher ad prices to be charged. Google will appeal; meantime, the government will decide what to ask the court to do to remedy the monopoly. Google also faces a new U.K. antitrust lawsuit over its dominance of search.
