I have deals website. I saw a website using "http://yourdomain.com/?deal=" link before every affiliate link or other offer/outbound links. Right now I'm manually using nofollow tag before any affiliate link such flipkart, amazon etc. or other play store links.
It would be better if you please tell me how to get http://yourdomain.com/?deal= link before every affiliate link automatically and then i will disallow it in robots.txt , it will save my much time Please help
