Google's new +1 button is the information innovator's response to the fairly ubiquitous Facebook, StumbleUpon, and other icons that let you promote content you find useful. I noticed that Google incorporated this feature into my search results as well, so I decided to experiment.
A popular blog post of mine describing a DIY screen protector for the Viewsonic G Tablet appears at spot #9 among my Google search results as shown below:
Note the greyed out +1 button just to the right of the link title, which animates tantalizingly as you hover over the search result. I went ahead and clicked it, essentially voting my link up in the rankings. Here's the result:
From the #9 to the #5 spot with one click?? I'll take it! You also receive a notification just below and to the left indicating that you've +1'd a given link.
I don't know whether "+1'd" has as catchy a ring to it as "Liked", but if it brings more traffic to my site, then I'm all for it!
