Since online promotion campaign started google and yahoo dominated most of the world, but still there are some more search engines which also help you to generate traffic for your website. Geographical factor always matter and google is not only dominated search engine in world. By research of most internet users Chinese, Japanese, Arabic, Russian users makes huge amount users. and reality is that they are not going with google or yahoo. Chinese users preferred "Baidu" search engine which is 9th ranked website all over world, with only Chinese users. while Japan is also one of the big internet user country. Arabic users from middle east , Africa and other parts also use their country preferred search engines. There is significant increase in amount of Russian users, they have their own search engine "Yandex". These are the countries who always known as strong power and never followed market leader, they have own answers and options for everything. They dont preferred dependency on other countries technology. I have list of more then 75 search engines with URL submit link which is already verified. It will not take more then 2 hours to submit your link on this search engines. output is really impressive. PM me if you interested in list.
I was not knowing that there are so many search engines available to work on....I would be glad to have the list of the search engines you have mentioned
Converting a website to another language in order to get properly indexed and clicked-on in that search engine is not always an easy task. While some of those search engines you mention do spider English sites, I wouldn't say a lot of the traffic coming from them is for a good purpose - if you know what I mean. I think you really need a site in their language, with a country specific url, to get meaningful results from search.
