Ok, so I'm using a simple .php code to cloak my affiliate links. I have a subfolder setup on my server called "go" for example that has all the php files in it and nothing else. I was reading some posts on here and didn't see a clear answer. Should I make a simple robot.txt to disallow search engines from crawling it? Does it hurt my SERPS letting google crawl it and having them find out that I'm an affiliate? That's my main question and only reason I would block G. from crawling it. Thanks for any help!
