[Tonmoy Ajize]

Hello,

Suppose i have

http://domain.com/how-to-post-on-black-hat-world (new one)

on which one i need to put canonical tag ? old one or new one ?

i know i need the put the opposite one but on which one that's not sure :O

You put it on the important "canonical" page, in this case the new URL.
