I was wondring if people could look at the source of this page and point out weak areas or possible problems.
It is basically just an ad that will be in a script, and I need to see if there are common problems if people just put it into a webpage. Should I also make it so if you click anywhere it works ( not just the link)?

Hmm, I have a couple comments.

1) Red and blue do NOT mix.
2) I recommend putting units on sizes larger than 0 (px, pt, em).

As for making clicks count anywhere, I personally do not like that, but it all depends on how much of an Adsense clone you want to be.

Ditto on the colors, but if you decide to keep them consider changing the text color to white. It'll be a lot more visible and will mitigate the stark adjacent-to-complementary contrast. That's also an accessibility issue, not just a design one.

I should have specified that that the colors will be variable.
So you don't like the click anywhere thing, I will think about that.
