Suggestions on using Ads?

[Pear]

Hello! c: I am looking to get some ads on my site that I will be able to make a small enough profit to host my site on its own domain. c: Are there any suggestions any of you can make? I was thinking about using Google Adsense, but I have never dealt with ads or anything, so any tips would be greatly appreciated. <3 ^-^

(It only costs about $4.00 a month to host on my current host, so I don't need a ton of money. c: However, I think it was about $140 for 3 years..)

Thanks! ^-^
