We are part of different affiliate programs. My question is:
If we have a link for the term Used Golf Clubs that is an affiliate link that looks like this, affiliatenetwork.com then it 302 redirects to our home page with an affiliate ID attached to the end of it (ex. www.example.com ?id=1234566). However, we obviously have natural links on other sites without the affiliate ID ex. (a href="http://www.example.com")Used Golf Clubs(/a} that are not using the affilaite ID. I would think this would be a duplicate page in Google (two different urls: home page url vs home pageurl with affiliate number in url), but I do not see any of these pages in google when I "site:"?

Does the 302 temporary redirect prevent these dup pages from getting indexed or are they actually in the omitted or supplemental results?
Should I be concerned?

In most cases, when a 302 redirects to another page in the same domain, search engines index the "source" URL and not the "target" URL. Are we talking about the same domain, sounds like we are but the example doesn't show that as being the case?

If it is a different domain, the "target" URL should be indexed but there could be some issue with the redirect from the dot com to the actual home page URL (ie index.html, index.htm, default.asp...). Either way, 301s pass PageRank but 302s don't.

Also, "Officially" Google "didn't" index URLs containing &id= until about a year ago.

Hope that helps! :)

Beu,

Thank you for the reply. It is different domains. We are the merchant and affiliate network creates the urls for each link to our site for affilaites to use. I am not sure if you are familiar with some of the affiliate programs, but many use some gobblygook url then 302 to a landing page on your domain, some have the affiliate company url 302 redirect to your url with the ID on it, and every other combination you can think of. The one I am speaking of above, would look like this:

affiliatedomain.com/blablabla 302 redirect to
ourhomepage.com?aid=123456

Again, I do not see these ULS's in google or yahoo and I am assuming it is not an issue because of all the companies using affiliate networks and no issues so far, but you know what happens when you "assume." :)

What do you see as the cached version of affiliatedomain.com/blablabla?
