Adsense ads is a totally legit way to make money online. Especially for the beginnier.
1. IT does not cost you anything to join.

2. They provide you with almost everything you need to get started. Including tips and great advice on how and where to implement your ads. Do NOT pay anyone for adsense help. Read their advice first you will save money.
3. They always pay on time...You can get paid by check or by direct deposit into your bank account...no charge. (You do need to make at least 100.00 bucks before you get paid if not it carries over to the next month).
4. You will not get rich but with a little marketing knowledge and determination you could concieviably make a good second income eventually maybe full time income.

5. The most important part of adsense is NOT to click on your own ads. Do not tell any of your relatives, friends, or enemies to click on your ads.
