Jenn, I'd agree with about the nature of PPC model - it's advertisement on 'direct marketing' steroid. It's biggest appeal, to me at least, is that PPC is extremely quantifiable (in its bare essence).
What rubs me in the wrong way, per se, is how often research (es) would focus on ad copy effectiveness vs. position. This primarily affects CTR (a form of conversion none the less) for the PPC campaign. Conversion for the product and/or service takes a place post-click-through at a specific landing page. Conversion factors at this point fall in POP (Point Of Purchase) realm.
No landing page can convert at 100%. Though keeping prospect(s) within the landing page would be desirable in most cases, there is an extremely effective conversion factor that's often underrated, path-through conversion factors.
One of the strongest and effective reinforcement for conversion is when a prospect 'browses' through the site after arriving at the landing page (no first round conversion there) and ends up at the initial landing page. Navigation/information structure/hierarchy and usability of the site play a mucho role here.
Scenario started with traffic, and then merchandizing keeps the prospect on the site/page. And, there is that whole conversion thing
Again...as you've already stated, it will take A LONG time before more corporations will be willing to invest time, money and effort in organic SEO/SEM, merchandizing and conversion factors.
Client education is a pickle...there is a no lie about it
Have a wonderful weekend!
