I've decided to take the plunge and get into PPC advertising to drive traffic to my affiliate offers. Now I know to make the most out of it, you should target ads to drive visitors to a very specific landing page. Should these landing pages be on different domains, or would it OK to simply create different landing pages for each offer on the same site? also, do you know of any examples of effective landing pages? Could you provide me with links to them?
that would depend on your offers, if they are around the same niche you could use one domain, if different its better to have separate domains.
Domains are cheap, and visitors may "be afraid" of clicking/buying something that does not even have its own domain. You can avoid this by using subdomains. At least that's what I think.
