Ultimate Blog Marketing

I’m trying to select a web hosting option and I like Yahoo (for its simplicity and decent price). But I can’t find an example or anything in their help about placing advertising on the site. I assume the answer is yes, but wanted to double-check.

I want to buy a starter package for my website and i must learn these:
1- When i take advertisement from yahoo,can i add whereever I want
2-I can add AdSense whereever I want
3-How can I gain money? Where is my money added (to my credit card ?)
4-Did you give PHP scripts automatically for editing

I wish to deploy a service similar to Google’s AdSense on my blogs (links to my blogs can be found in my profile on Yahoo! Answers). I wish to know whether Yahoo! Publisher Network is an offering equivalent to Google AdSense? If it’s different, then what is it and in what ways is it different from AdSense?

I currently have a free website with Yahoo Geocities. I was wondering if I could use Google Adsense on it. Or is there something that states I can’t do that with Yahoo? All the terms and conditions are a little confusing.

I have set up a new website and wanted to put some advertisements, and I wanna explore some other options as well instead of the so common Adsense by google. Is there any alternate thing that I can do?
