So, I have a question about the duplicate content issue when you append tracking codes. I've just sent out an email with a special link in the signature which points to one of the Google-generated URLs. With that URL, I'll be able to tell to whom the email was sent and when. But, as a safety measure to avoid duplicate content, I've included a 301-redirect in the .htaccess file, as follows:
Redirect 301 /?utm_source=Email&utm_medium=Newsletter&utm_campaign=0510 http://www.mysite.com
Will this fix it or do I have to use the canonical element? I'm concerned about passing link juice.
Glad you liked the article!
No, you don't want to use a server-side redirect such as that, because the tracking data won't be captured that way. Because you're just sending it via an email, if you don't expect people to link to a URL, then I wouldn't worry about it. But if you feel there is a chance some might link to it, then yes, the canonical link element (rel=canonical) is the perfect solution for this type of problem.
