There can be a lot of possible budgets. We can start from 30-50 USD for instance (if we don't like to overspend) or we can even put down hundreds of dollars.

How much do you invest in Adwords in a month?

Hi Friend,
Good Day. Do you think Google adwords gives you good business?. I think the spending is more than the business through google adwords. Please reply if you have good business returns.
Thanks.

I invest Zero Dollars so far because I have yet to try it, been considering it tho. I've heard some people have gotten really great re$ults from it -- and others have lost their shirts! I'd definitely laser-target my market with well-focused keywords - and have a budget set aside that I can afford to experiment with if I were you.
