The two biggest things Yahoo needs to work on (and Google should never stop trying to improve) are:
* relevance of the ads to the page
* compelling copy in the ads themselves
On days when my earnings seem lower, I've noticed many of the ads just don't make you want to click. I've also seen variations, from one day or week to the next, in how well targeted the ads are to the copy on the page. The more targeted, and the more compellingly written, the more likely people seem to be to click - which is of course good for us and good for Google and/or Yahoo.
