Dear Friends, i want to take your valuable suggestion on affiliates based sites. Is Google gives values to such types of sites. Is it possible to optimized well affiliates sites. Please pass me your suggestions.
All the content you get from an affiliate site is duplicated by other affiliates running the same stuff. As a result, Google won't rank you unless you have A LOT of unique content. If you want to be optimized for an affiliate site you should put the affiliate stuff on a domain that WON'T get ranked and then use another domain with your own unique content that links to it. Your unique content will get ranked in Google and can serve as a lead generator to the affiliate site.
If you're looking to build sites solely dedicated to promoting products as an affiliate, I'm not very sure you'd be successful without an iron-clad roadmap laid out with previous experience at this sort of thing. I've also heard that mini-sites with nothing but a landing page are penalized by Google when it comes to both SERP rankings as well as AdWords. What I'd personally recommend is that you build a site with good, informative content, let it incubate, and then monetize with affiliate programs, AdSense etc. If you have content that's good enough, you'll definitely get good traffic and Google will even start giving you a piece of that SERP pie
