If I have a Primary KW: yyy for pain and I optimize it for a post. The same keyword comes up a couple of times naturally on another post. Will that be considered as cannibalization?
Think about it this way....
If someone searched for [primary keywords] online, would those articles satisfy their search intent, and are they addressing that intent the same way? If you answer yes to both of those, then you might run into keyword cannibalization.
