The Google social api is sneaking up on us and I think its going to become a very good tool that we need to take advantage of. Google is hunting for suspicious links and the easier you can associate what the link is for the better. Its kind of been queit but here is basically how it works.
In your link include a rel=. The rel (relationship) tag is not new to most people but unfortunately people know it ONLY as rel=”nofollow”.
If you want to embrace this new social api (which imo will start to influence search results) then you need to know about some of these relationship tags.
me – For any of your social profiles give them a rel=me. This is important because you are the authority for you.
I will give you an example. I am the authority of shoemoney (for now anyway). But someone else owns the shoemoney aim, msn, myspace and other profiles. So how does google know which one is truly mine and how to rank them when someone searches for “shoemoney” ????
Well in using the rel=”me” tag in your link IE:
<a rel="me" href="http://twitter.com/shoemoney">Twitter</a> <a rel="me" href="http://www.youtube.com/shoemoney">Youtube</a> <a rel="me" href="http://www.myspace.com/ringtoneking">MySpace</a>
You get the point.
This tells Google and anyone using the social API that not only am I linking to this twitter profile but I am saying it is me. (duh).
There is a lot of other relationship tags you can use but I think the “me” one is probably the most important for most people. Especially bloggers.
