Google is not done trying to push Google+  and has snapped up the online poll startup Polar to work on mobile design for the social network.

Google, the world's largest internet search company, announced Thursday that it has acquired an online polling startup Polar in a bid to bolster Google+. The search giant has not been too lucky with its social networking efforts in the Facebook-dominated web space. But the company isn't done trying yet, as it constantly makes new moves to help boost Google+ presence around the world.

Polar specializes in instant online polls through smartphones, tablets and PCs.

The polls are generally an either/or options.The service can also be used for getting people's opinion in selecting a logo for a startup. The startup's concept of quick rating has helped it serve more than half a billion polls in the last eight months and had 1.1 million active voters in September, the company's founder Luke Wroblewski wrote in his blog on Thursday.

Google confirmed the acquisition in a Google+ post, welcoming Wroblewski and his team to make "G+ even more awesome." It is unclear what exactly the new team will work on with Google+ but Re/Code notes that the new work will include mobile design for Google+. After all, the Wroblewski's writings and observations, which include the book "Mobile First," serves as a highly respected guide across the industry.

Polar said in its blog that the company's tools will run till the end of this year, post which it will allow its customers to download and save archives of the polls and data.

"As for us, we're delighted to be joining the Google+ team and bringing our arctic circle sensibilities to sunny California," the startup wrote.

The acquisition fuels Google's efforts to build a stronger base for its social networking service. As of October last year, Google+ had 300 million active users. But the number is a fraction compared to Facebook's massive 1.2 billion user base.
