Is it worth using google adwords to advertise my business, read inside?

[Constantin]

The fact that you had visitors but you could not see any difference in income may mean 2 things:

1. You're not targeting the right market;
2. Your website (or wherever they get to when clicking your add) is not optimized for conversion.

If you haven't use AdWords before, I advice you to use an expert's services. AdWords works, but you have to know what you're doing.
