How to Block Affiliate URLs

[gunjanp]

Hallo,

I have one site i have done seo for that site. We are also running affiliate campaign for our site. so my other pages indexing with affiliate urls in the Google.

So i think this will creates duplicate content issue for me.

Now i have two suggestion for solving this issue, but I am not sure that they are effective way so please let me know. This is the right way or not.

1. Create Affiliate folder on server and place same pages of sites there and block this affiliate in Googlebot..
2. If we place <rel="nofollow, noindex"> tag on every affiliate links. Not in page..

So which one is the the good solution for me.

or anybody suggest me that how i can block this kind of affiliate urls. These types of urls increasing more and more day by day.

/product.html?a_aid=6bee5108&a_bid=d08e3667
/product.html?a_aid=80c69612&a_bid=95308704%20
/product.html?a_aid=6bee5108&a_bid=95308704

how to block these urls through robots.txt or any other programming ways if you know please let me know.

I am waiting for your reply, Thanks

I would go with either duping the pages into a separate /affiliate folder or sub, affiliate.example.com. And, instead of using robots.txt, I'd use the meta robots noindex on each page to be absolutely sure these pages aren't indexed"

<meta title="robots" content="noindex">
