Site visibility within Google is going to have a heavy impact with the introduction of the Google +1 button. Here are the top six things everyone should know about it:

1. Search rankings.

Google’s David Byttow announced "We'll also start to look at +1's as one of the many signals we use to determine a page's relevance and ranking, including social signals from other services. For +1's, as with any new ranking signal, we'll be starting carefully and learning how those signals affect search quality over time."

2. Your Google Profile.

To be able to make use of the button in search engine results, you’ll need to create a Google Profile and enable it. Go to Google Account Settings then to Personal Settings and there will be an option that says +1 on non-Google Sites. You then need to make certain that it is enabled. Once you start clicking the +1 button, they will show up on your Google Profile.  

3. Qualified traffic.

Like word-of-mouth, people will be able to see these recommendations from people they personally know. This means more qualified traffic will be directed to your website, which will be traffic that is most likely to convert.

4. Buttons for your website.

There are different sizes and styles of the button you can implement on your website. Click here for instructions on how to set these up.    

5. Sign in.

Remember to sign into your Google account for these recommendations to show in your search results.

6. Google crawl.

In response to the button impression or click, Google may crawl or re-crawl pages with these +1 buttons, and store the page title and other content. Will you be making use of the Google +1 button?
