The big Google news from yesterday was that they officially launched the Google +1 button for webmasters and site owners to place on their sites.

You can get the code to add the button to your site by going here. We have already replaced our Google Buzz icons with the +1 button. Why? What is the difference between Buzz and +1? Google said:

Personally, I still think there will be a lot of confusion between Google Buzz and Google +1. When you “like” stories in Google Reader, should that be a +1 but when you comment in Google Reader, should that be a Google Buzz? I don’t know.

Matt McGee at Search Engine Land has two good stories on the button. The stories are named:

It’s Here: Google +1 Buttons For Websites
Google +1 Analytics Coming Soon; Here’s What To Expect

How will it affect SEO and results? Google said:

When will it show in analytics? We do not know.

The one thing not mentioned in most blog posts is the code. Google is actually recommending using the HTML5 syntax instead of what Google gives you on the button creation page. The code they are recommending is: <div class="g-plusone" data-size="standard" data-count="true"></div>
