Just a bit of information on how Yandex ads work regarding payments.
When we started a Russian website the plan was to put Adsense and Yandex ads on the pages. The Adsense worked OK immediately but Yandex would only serve ads if you exceeded a specific number of page view per day. Prior to reaching that level, Yandex would not provide any details on how they would pay for the ads. We assumed it would be similar to Adsense.
We reached the required number of page views and applied to join the Yandex ad program. We were accepted and only then told that payments could only be made into a Russian bank account. Living in the UK, it's next to impossible to acquire a Russian bank account so that's the end of the Yandex ad program for our site.
Annoying, because although Adsense works fine on the site, the ads are poorly targetted and earn little money. I suspect the reason for this lack of targetting is that the Russian internet market is still under-developed. There are simply not many Russian businesses advertising on the internet. I am sure they will get there in the end but it is likely to be a long haul.
Thanks for posting your findings - they will be valuable for people wanting to start publishing in russian. I've heard from others in Russia that Yandex is the no.1 player, so it's a huge mistake if you ask me that they firstly require a certain threashold of page views before allowing you to show ads. Next up is more than critical that you only can receive funds into a russian bank account.
