I am having a hard time what to choose in driving traffic to my shopzilla based www.clickgrade.com shopping comparison site. It is mainly computer price comparison on the front page and has about less than $1 per output in commission per action (correct me if I am wrong). I tried google adwords but they charge about more than my commision, in short I may be losing money if I tried it. I haven't tried SEO yet. Can anyone give me tips on how to use google adwords to drive traffic and not lose money? And if SEO is a better option. Thanks. I also have www.priceter.com, www.savemoregetmore.com, www.dogcomputer.com and they are all shopping comparison shopzilla only website that needs the same traffic solution.
