Yandex now is working hard on anti-spam technologies, Aport is very secret to us :), but it is clear, that if you are not in their catalogue, it is difficult to get high rankings. But you can buy 'zero-link' for $150 per 1000 shows. :)
Rambler is stupid :), but also have some anti-spam techs.
Well, about 'free s*x p*rn*' - maybe it is surprise to you, but russians mostly use russian language! :) So anti-spam techs made for russian words!
Some additional info on Yandex:
There is three steps of indexing by Yandex.
1. Your site (first registered page) will be in index in 15 minutes - if your servers reply in <3sec. and have .ru domain. Usually, you will be quite high in search results
2. During 1 week Yandex-robot will came again and index all pages of your site. After that it will give you a real relevancy. (CI, anti-spam)
3. It will came again to measure other parameters of your pages
It came quite often :)
Rambler now changing their robot, so we're waiting for results.
Aport is quite good SE, but Aport-developers doesn't came to our local SE-forums and don't answer email. Quite strange people :)
Well, it depends on words :) If you use english - it is a mistake. Russians like to use Russian. That russians, who use english, go to Altavista and Google.
BTW, it's OK to ask the popularity of words from SE-owners. Just write a letter with words wich you want to know the popularity and they will write back you a statistics in 1 hour (especially Yandex).
Some clarification on directories and ratings.
There is no practice of ratings in Europe and America, but in Russia it is very powerful instrument for promotion (especially Rambler's Top100, [top100.rambler.ru...]
It is not a directory! It is structured lists of pages, which are listed from most popular to less. To participate in rating, you should register there and put a 81*33 button to your page. After that this button will count your visitors and place you in rating. Hope, it's clear :)
Rambler's Top100 is most effective, if you have good traffic. And you have many visitors, you will have many reffers from their rating. People really use it.
Well, tired to type, hope, it was useful for you. And if you have any questions about russian SE - write me. And also you can include me in your list on the top of this discussion :)
