How much is designed for a user, and how much is designed for the company to ensure click-throughs to a goal?
depends on the goal, but maybe the most usually its focus on the users (90% user - 10 % company) Its just my point of view. If your user have a good experience, you'll can reach any goal.
That's pretty much where the split is in my mind too. If the UX is poor, then it doesn't matter who/what the company is.
