Please, how does ads work?

[Nicki Minaj]

Hello
My school just opened a charity foundation and they said we can donate money,food and stuff like that so i was thinking on using ads because i spend 70% of time time on tumblr lol so if anyone can tell me how does ads work?, how much money i gain with a click? i have 2 computers on my house so i can click myself with my other computer? and how many times i can click myself?

thank you so much! it means a lot for me

ps:i have a job too but the ads would be an amazing help!

Don't click your own ads, that's the quickest way to be banned for life from an ad program, they track IP addresses which would be the same for both of your computers, as well as suspicious patterns.

There are many ad systems that pay for clicks on your site, earnings may average roughly 1 cent per unique visitor. Google Adsense is the most popular for small blog style sites, though the $100 min payoff level can take years for a small site to earn. Sorry I don't know the tumblr ad terms, some sites split revenue, typically the sort of ads you can use on free sites is restricted.
