A new Google+/+1 feature has been spotted in the wild that further blends organic results with social information. Early today State of Search and charliesaidthat noticed a thank you link on an organic listing next to the Google+ users who +1′ed a result.
If logged in as a Google+ user we could get this functionality to appear sporadically on a range of search terms. In order for the “Thank” link to show, the link in the results had to be +1′ed from a circled user. This functionality is currently only showing intermittently at the moment. A Google rep did not comment further on this feature when asked for more information.
If a searcher did choose to thank someone for the +1 they were prompted to thank directly on Google+. The message automatically contains the original +1er on the post:
This limited visibility post is shown directly on the wall of the user who is doing the thanking. If you are looking to keep your appreciation of the +1 private, just make sure you don’t add in any other circles to the message:
So don’t be surprised next time you’re thanked for a +1 on your wall. We will continue to follow up on this feature and any official announcements.
