Hi all anybody try Google Co-op. i'm try to set up but it is not really working. Please let me know any tips.
Are you talking about the co-op search engine? I use one on a google pages site for web directory searches.
You can create a search engine that only gives results in a nice that you want. And you can add your adsense in the results so it brings in some cash as well. I use it in a couple of domains and it works perfect. I can not imagine that it is hard to set up. Just follow the steps to implement it in your site.
