Can you explain how an outbound link from your site to an authoritative site gains you ranking? While I can see how getting a link from such a site to your site boosts your credibility in google's view, I don't understand how the reverse works.

Thanks! You've got a lot of good stuff to share Tommy!

Great training, thanks Tommy :)

Thank you Tommy, as always useful stuff from your kitchen.

Great training. Thank you very much Tommy. Much appreciated.

I will definitely keep this in mind, a great simple way to increase ranking. Thank you very much for pointing this out :)
