The question about affiliate links and google serps has been discussed several times but I can't find any discussion on our own situation.
Many pages on the site have an affiliate product search form, method = get. The affiliate site doesn't work with 'post' forms, so has to receive a 'get' type query.
Our site has been demoted by both panda and penguin and I understand from the affiliate company that many of their affiliates have experienced the same problem.
I understand that 'post' forms are never followed by google, so would it be a good idea to change these forms to be type 'post' to a page on our own site, blocked in robots.txt, that then redirects to the affiliate site as a 'get' type query...
...or is this seen as a sneaky redirect or cloaking or something else that might make matters worse?
