> It is interesting that non commercial sources have more of a voice on these search engines than on Google today. I sort of agree, I also sometimes use Yandex and am usually positively surprised. I can immediately see two reasons: A) SEO efforts are targeted Google/Bing, not other search engines that don't focus on the target market/language/region. Of course that argument can be twisted around: these search engines don't focus on Western languages, so could in theory be more susceptible to SEO trickery. It's interesting that they aren't. B) Ad money. Google is strongly incentivized to prefer search results that show Google ads. For foreign search engines there is no money to be made, so they can disregard that signal.
