Newbie Landing Page Question

[ItsDavid]

Hello all,

I am currently building out a database of landing pages with different offers using different networks so that once finished I can just concentrate on promoting the pages and can put building behind me. I am basically duplicating the offers pages to allow for tracking and also attempting to SEO them as a second source of traffic. Is this typical to just duplicate the offer pages or should I build pages that look totally different from the original offer pages?

thanks to all in
