Where to put canonical tag ?

Question

hi,

I have learned the uses of canonical tag recently. Now, my question is. suppoose i have one master page -

Targeted webpage page - www.example.com/science/medical-science

Another page (clone) - www.example.com/science/medical-science?//586?789

Now suppose these two are basically same webpages, i want all my visitor of link juice to be flown here - http://www.example.com/science/medical-science

So shall i put the "canonical tag" in the source code of the "clone" page ?? like -

Do i need to put any canonical tag here as well - www.example.com/science/medical-science ???

Please provide the solution as soon as possible.

Thanks in advance

Officially you only need it on the other pages that you want to point to the original page, not on the original page itself.

However it's still a good idea to put it on both pages. Often this is the easiest thing to do because duplicate content usually comes from the same back-end script or code.
