Adsense team has sent an email to its publishers informing them that they are going to receive +1 stickers in the envelope of their payment and email as received is as appended below:
Dear Publisher,
As a token of our appreciation of your continued participation in the Google AdSense programme, we have sent you a couple of +1 stickers in the envelope with your AdSense earnings this month. You can sport them on your laptops, and even share them with your friends!
Over the past few months, the +1 button has been helping people receive recommendations from their friends where they’re most useful, right on Google search.
Putting the +1 button on your site lets users share your content with their circles on Google+, potentially allowing you to expand your audience and bring in more relevant traffic.
Additionally, by giving people a chance to +1 your content, you might see a greater number of total +1’s on your pages. This in turn could lead to more personal annotations on your content when it appears on Google Search, and more and better qualified traffic coming to your site.
Implementation of the +1 button only requires adding a few lines of code, so have a look at the +1 configuration tool, generate a code snippet, and let your users start sharing your content to Google+.
Hope Google+ is going to change the way people are searching the information and are getting an input about the same as quality information is the right of every individual. No doubt Google is doing a tremendous job of bring quality information for the users.
