My site have an affiliate program with thousands of affiliates linking to my site with a like like website.com/index?af=123&pro=abc&img=xyz
Apparently Google doesn't like this kind of links because is not taking them into consideration. A competitor of our site is using links like website.com/index/123/abc/xyz with a redirection to the home page and looks google like more this kind of links.
Anybody can confirm what I suspect? Anybodu had previous experience in affiliate program links?
Thanks

Bump.

Links like this are actually fine:
website.com/index?af=123&pro=abc&img=xyz

So are links like this:
website.com/index/123/abc/xyz

It's not really the URLs, it's actually what happens when someone (or a search engine bot) goes to one of those URLs. Most likely the competitor is using a 301 Permanent Redirect, which is what should happen when you use affiliate links. This way the merchant gets all the inbound link credit and not the affiliates themselves.

Thank you. That was extremely helpful.
