How do you properly remove dynamic links from search that are causing duplicate content (from a plugin)?

I used canonical to point to the .co for each page. I’m not sure if that’s enough (time could be a factor) or best practices.

Does anyone have a link/guide or any advice on this matter that could assure me I’ve done this step properly?

Thanks.

Welcome to WebmasterWorld!

Google state that the tag is for duplicate or very near duplicate content, so if the content at the two urls is substantively similar then it should work. That said, Google state that one of the biggest mistakes they see with canonical is people using it for pagination because it stops pages after page 1 being indexed. So from that (and my experiences first hand with this) I would say it should result in those two additional urls not making it into the index.

It's not really an 'amalgamate' tag it's an 'exclude all but preferred version' tag - at least that's the way I've seen it work myself.

My preferred solution where possible though is to insert a meta robots 'noindex' tag into the <head> for variants of a multi-stage page e.g. contact?action=check and contact?action=sent.
