Last week I posted on why Google “Plus Ones” help links pop more in search results than Facebook likes. Here’s some great tips straight from Google on how to makes the same Plus magic happen in your ads
George creates a Google+ Page for his company, Happy Burgers. He also creates an AdWords campaign, some ads, and then a social extension by linking his Google+ Page to his campaign. When 32 people +1 one of his ads, Happy Burgers’ page will receive 32 new +1’s. Alternatively, if George connects his AdWords campaign to his Google+ Page after it already had 32 +1’s, all of his ads can now have these +1’s as social annotations.
