I run a simple website for my sister's business, giving a quick overview of the stuff she does - screen printing, leather interiors, leather folders amongst other things.

Being a technophile I think that one way she can develop new business is to get decent visibility in Google, which would rely on using adwords since there's little chance of getting a high ranking bearing in mind Google's methods and algorithims.

She's not convinced, and thinks that it will cost her 10GBP a click for no return.

Does anyone have any experience with adwords? I know that horses for courses, but I wonder if the CPC for my sister will be nearer 5p than 10 quid.

Any advice for or against? Thanks!
