Welcome to the Q&A Forum

Yes it does thank you. When I run the campaign it says I have two on some pages and I need to remove them. ( I am using WordPress so I assume this was an automatic tag it added - odd) So I will try and remove it and see what happens at next crawl. THANKS

Do you do any guest blogging to obtain links, I have found this to be effective for link building and it has increased my search engine results.

What is Canonical URL Tag?

Thanks for the comments, I appreciate other points of view, you bring to light things that I haven't considered. I do alot of guest posting as well I find those links really valuable especially when I am lucky enough to be on high PR sites as a guest post.
