**4/20/11 – This may not work anymore. It doesn’t for me.
This is pretty straight forward and easy to do, but I’ve included a few images here to show what I have done to enable a DoFollow backlink to my website from my public Facebook profile. When you are logged in your links will be NoFollowed, but by doing what I’m going to show you here, your displayed website address will be a DoFollow backlink at your public Facebook profile URL when is viewed by logged out users and, of course, crawled by the search engines.
I’ve chosen to use a custom privacy setting by clicking on the “Custom” navigation link on the left. After that I clicked on the customize settings link as show circled in yellow.
On the customized settings page I chose to allow my website to be viewable by everyone.
There is no save button on this page, so you can just go back to your profile from here and your new setting should be saved. Last you need to have set a website address under your contact information as shown below.
Now your first website address should show on your public Facebook profile – as a DoFollow link – like it does on mine.
