I recently promoted this program (pre-Halloween) with Google Adwords and it taught me a few things that other people might want to know.

First, keeping on top of current search trends is a great way to make money. Seasonal keywords seem to be much less expensive than most, even when they're very popular. My ads got over 500 clicks in a little less than 3 days in the middle of October and I was paying very little for them.

Second, unless you're selling something very expensive yet very popular, 6% is not enough commission to work with Adwords. Even though I sold several hundered dollars worth of costumes through my ads, I still didn't make enough to cover the cost of all those clicks (even though they were cheap). If I had been getting 8%-10% I think I migh have broken even. With 13%-15% I wouldn't have stopped my campaign when I did.

So be careful. I've decided that a fixed payment per order or lead is safer than a percentage, at least when you're selling with Adwords. If I had a Halloween site things might have been different.

So that's my 2 cents, hope you like them.
