Google +1 Button

Google is in the process of implementing a new social sharing tool called +1. This is similar to the Facebook “Like” button, but will be integrated into all Google products including organic search results. We will start seeing +1 this month, and the ability to add it to your site shortly thereafter. The impact of +1 on search engine optimization is unknown at this point, but we will continue to keep our clients in front of important developments.
