Nothing seems to go right for Microsoft (NASDAQ:MSFT) anymore. Consider that its Bing search engine has fallen from the No. 4 spot among the world’s largest. Russia-based Yandex (NASDAQ:YNDX) has pushed Bing aside, according to a report from comScore.

Based on the number of queries in November, Yandex got 2.8%, and Microsoft garnered only 2.5%. Of course, the largest search engine remains Google (NASDAQ:GOOG), which has 62%. No. 2 is China’s Baidu (NASDAQ:BIDU) at 8.2%, and then comes Yahoo (NASDAQ:YHOO), with 4.9%.

For the most part, Yandex has benefited nicely from the continued growth in Internet usage in Russia. Growth has also been strong in surrounding areas like Ukraine and Belorussia.

As for Microsoft, it has launched a national ad campaign to boost Bing’s fortunes, but it seems to be going nowhere. Besides, the search industry is moving rapidly toward mobile devices. Unfortunately, Microsoft’s efforts in this category remain fairly lackluster as well.
