I am about to use onsite discount module for affiliates. Each affiliate will have his unique link: www mysite.com/saveab10 www mysite.com/saveac10 www mysite.com/savead10 etc... Which they will post on their blogs. The aff link will lead to our home page in 2 redirects. Here is the diagram: Will this kind of links help our SEO? Or should i replace 302 redirect with 301 redirect?
