Google+ Pages with 1,000+ followers can now create +Post ads, promote Hangouts on Air and automatic posts
Google today expanded its test of +Post ads, a new type of monetization for its social network that lets brands turn Google+ content into display ads. At the same time, Google is piloting two new features: promoted Hangouts on Air and automatic post promotion.
The new advertising format is now available to all advertisers who meet the following requirements:
They have a Google+ page with at least 1,000 followers.
They are using a post that contains content relevant to their audience.
They have opted in to shared endorsements for Google+ pages.
Those "follows" are about as quality as all of the other, "we will get you 1,000s of followers" which have been proven to not only be very low quality, but also can be seen by search engines as spammy. I would recommend becoming involved with Google plus. Over time your following will grow. Share on your other social streams that you're on google plus, enter and be involved with communities, and like any other social site make sure to constantly update with fresh material.
