Here's the situation. I get a domain. I create a frames site. I use meta tags and put relevant content in the no frames tag of the main frameset page. However, the main frame of the frameset has a meta redirect to an affiliate program. So when you open the page you get instantly taken to the affiliate site but it appears to be on your domain.
My question is, will the SE penalize this setup. I'm worried that the redirect on the frame will cause problems (seen as cloaking?) even though the frameset page has no redirects in the meta tags.
I cannot give you a concrete answer as i am not 100% sure myself, however, my first thoughts would be that this is not a good idea. Technically you would have meta details e.g. keyword, descriptors etc that do not match your site. Could be looked upon as 'cheating' by the search engines.
As i said, i do not have a definite answer...these are just initial toguhts......hope they are of some good to you.
I use to use that all the time for doorway promotion. They got indexed but the trick was getting good links the domains so they would stay in the index. You can try linking to them from your legitimate sites but you run the risk of being reported and getting penalized on your other sites.
I think the best way is to build a small unique site for those keywords. Because inbound links play such an important factor in google, your domain idea may not do well as the only people that will link to that will probably be you.
