Does SEO ACTUALLY increase sales?

[Denverise]

Hi Everyone, For all its press and marketing hype, does SEO actually help increase sales? I am aware it would increase traffic...but the internet as a sales vehicle is still growing and I was just wondering (without asking anyone to be specific with figures and stuff) after SEO has been implemented, have sales increased? I'm also aware that actual on-site elements and traditional marketing techniques close the sale...but in general, does SEO generate more sales...

With the right keywords... yes.
