Internet Marketing

I've been doing pay-per-click advertising on google for about a year now and have found it extremely frustrating, for while it does bring in a fair amount of traffic, it doesn't lead to a lot of actual work.... maybe my keywords are too general, or maybe I'm getting a lot of do-it-yourselfers who want to see photos they can imitate, and very few real customers. probably am paying even for my own competition to click on my banners...

so, i'm looking into other methods. site-targeted ads seem like a hit-or-miss proposition as well.

is it better to use the same keywords on each page of your website or to change the keywords to address the subject of each individual page? which leads to more traffic?

any other thoughts on marketing?

referrals still seem to be the best way to get customers -- free community bulletin boards have brought me more business than pay-per-click. if only there was a way to broadcast referrals to a larger audience instantaneously....
