We have been using Google ppc (has some cost) but we have a good margin on return when someone buys our products so we easily compensate the expense with the exposure.

Of course we are always looking for other means to generate sales...I find our product is unique enough, just letting someone know it exists generates sales, hence the largest serch engine.

I am thinking about having someone manage our site on SEO and such to become better pageranked and better exposure to try to eliminate some of the ppc costs, but that also bears costs so which is better...I am not sure.

As for the others, shopping.com - price grabber, they are ppc as well dependant on your items would determine if you should use them. Ex. on electronics, you type in a particular item and it shows on those sites with a best value price on it...so as a consumer, I would probably look for the best price and make the purchase as it is all the same product. Is that a good way to spend ppc dollars, I personally do not think so unless your prices are simply unbeatable.

Well, I hope I put something into this that makes sense and can help you...GOOD LUCK
