Just guessing I'm afraid, but could the key to a "Great" QS for a given keyword/Ad/Landing page combination be about providing Ad Text and Landing page content that is both relevant and specific to the keyword concerned.

Systematically following the steps taken by limoshawn will go a long way to achiving this, and for limoshawn it is all valid since the specific keyword is actually being offered for sale on each of the landing pages.

However, blindly following these steps without actually ending up with valuable content on the landing page (Content pumped full of keywords will be relevant but may still be worthless - e.g. "brown widgets are widgets that are brown etc.") will not provide a rubust fix.

OTOH - providing lots of valuable, relevant and specific content without necessarily following all the steps suggested will, IMHO, still provide a Great QS
