I suggest people of all ages get adsense right now. Its easy money and even if your too young you can keep your payments on hold untill your 18 and get them then. Begginer sites that only get 20 - 40 hits a day will still get $20 a year

get 200 - 400 and you'll be glad you got it

"hold off till you're 18" How do you do that? It'd be over 30 months away.

You can't "hold off", and getting 20-40 hits a day still means you have to wait 5 year before Google pay out, they only pay sums above $100.

Probably about £30.00 in UK Money after rates, commission and postage, and thats only about a £5/year, and your domain costs more than that. So whyh have ads when you lose a lot of customers, more than £5 worth a year of customers a year because they think your site is cheap.
