Google+ is an amalgamation of several services we already use. Basically, it takes all of the search engines and makes them into one big social network. This will make it spread the word about your website(s) quicker and you'll reach a wider audience. If you're looking to promote your website using Google+, putting the +1 button on your website and on individual articles (your content) will help do this. You're going to want to give your visitors a reason to click that +1 button so try adding links, videos, images, etc. to your content. Doing the above will enable Google Plus's "Sparks" features. This will show users similar articles, videos, images, etc. to what they have already looked at. So if you're taking advantage of getting a quick +1 using your BAF credits, those users will automatically be told that they should be looking at more of your content. Simple, right?
