.ca & .com difference

One of my sites PR is 6, the other is a 5. The difference? The 6 is a .com
and the 5 is a .ca, the only difference I can think up of that would cause the PR difference is the amount of people linking to one site
as opposed to the other....anyone know anymore?

yes, that's why it would be different.

you should really only use one of the two sites, and use a 301 redirect from one to the other.

this will "channel" the PR from the page/domain you're not using and transfer it to the primary domain.

if your canadian site is in french then you would probably want to use two separate sites. if your sites both have the same content and intended market then a 301 redirect would be a good call.

And take it very seriously, if you are using two sites with same content or just redirecting the (except 301) you will be banned soon, and if you are located in Canada (ur server) chances are your .com site will be banned, so before its too late take the action right now....
