Welcome to the Q&A Forum

Hi Mark, thanks a lot for very informative reply. Definitely my strategy is going to put unique, related & fresh content on primary site but want to use this international domain as a traffic source since it will come up in organic searches easily. Content of both sites will be in Farsi forever so actually I don't/won't have international content to focus on each market individually. However just a quick question about your coca cola example: is it possible to set a canonical tag in gateway (international) sites to refer to main website (English coca cola). Does it help with giving all credits & scores to our main site? Thanks for your time

I would agree with Aran, show all your content first then hide it in the page load event. I wouldn't actually comment out the content, I would rather use "display:none" on the container div. Showing and hiding content sections with AJAX is very common these days so it shouldn't be a problem, provided it's done correctly.
