Google+ struggling to win over brands as social network sites thrive

To mark the Cinco de Mayo holiday this year, Domino’s Pizza festooned its Facebook page with a string of posts, including an image of a Mexican- themed guacamole pizza that garnered over 2,000 “likes”.

But visitors to Domino’s companion Google+ page on that day found less festive fare: The most recent post was from Oct 2012.

Some two years after introducing its social network, Google is struggling to win over the brands and businesses that have been its most loyal customers in the search engine market.
