Google Inc. has acquired Facebook marketing company Toro (Red Hot Labs Inc.) for an undisclosed price.

Based in San Francisco, Toro claims its services offers the best way to run high performance Facebook campaigns for mobile apps. Their service offers split testing (A/B testing), lookalike targeting, and automatic bidding optimization, all packaged in what is claimed to be an easy to use dashboard.

In a statement on the Toro blog the company said that since launching three years ago, they’d “built multiple products in the mobile space, worked with some great partners, and have helped hundreds of apps grow their user bases.”

“With greater resources and distribution now available at our disposal, we’re excited to join Google and continue our mission of making the lives of app developers easier” the statement continued.

Toro said that they would continue to support existing customers, however new campaign creation has been suspended and they recommend that customers take their business elsewhere if they want to roll out new campaigns.

Which then leads us to the obvious question: if they’re basically shutting down what’s the appeal for Google?

It could be a technology buy, but likewise there’s nothing remarkable about what they offer compared to a dozen other companies in the space, and it wouldn’t be hard to replicate.

It could be a talent buy. The founders of the company were the founders of a company called MyMiniLife which offered the code and idea Zynga used after they acquired it to launch Farmville.

What it doesn’t appear to be is Google getting into the Facebook marketing game.

Founded as Red Hot Labs in 2012, the company raised one round of $1.5 million in February 2013 from investors including Justin Waldron, Andreessen Horowitz, SV Angel, General Catalyst Partners and Greylock Partners.
