Can someone help me out with this. I read through the policies for the custom search bar but for whatever reason it's really not sinking in with me on how many ad's I can put up on a page with the search bar.

It's a Custom google search but I have added no keywords of my own. Now, if I have it on my home screen, from what I understand I am only able to put one more ad up. Is that correct or am I misguided a little bit here. For the time being my home page basically has the search bar and one 728x90 text/rich banner. Am I to leave it at that or may I ad more on?

Thanks for any advice in advance, I am completely new to the program.
