I agree the most important thing is great rank worthy content.

However, if you build that content all in flash, setup your robots.txt incorrectly, or any of a number of other technical snafus then you can screw up your rankings. Hence why it is important to be setup in the right way for the search engines to find you. Otherwise you will miss out on on most of the traffic.

I've done full SEO campaigns with larger budgets and currently manage millions of paid media on search engines and other places.
