I recently added the plus 1 button to my website and read through some of the suggestions. Google recommends placing the button at the top of the page, close to the logo, to make it easier for visitors to use it. My translation of that is, they want to brand everything. I placed the button in my footer, below twitter, facebook, and LinkedIn. I don’t believe many people will use it, and definitely not important enough to basically co-brand my websites.
The info I read on the Plus 1 button mentions it will help filter relevant search results the more people use the button. We will see if that helps but plus has a long way to go to become as mainstream as Facebook. Right now, only my tech friends are using plus and the soccer mom’s are still addicted to Facebook. Converting them will take years.
