Watermarking can have an advantage in Google images. If you have lots of images your brand will show up often and people will get to know it, without ever having visited your site.

For countries where it is not possible, I would suggest if you must have the domain, a cheap virtual office is an option to take. This way you have an address in that country to use. Not many people know about this option.

Having a good linking structure that is clear on your site, will help promote that. However you will also only get sitelinks when your site is an authoritative source for that search term.
