Yandex gave us a gift by adding a new keyword operator to wordstat.yandex.ru – square brackets
. This operator makes word order fixed, so now we can finally know for sure that the "ticket Moscow Petersburg" keyword is noticeably more popular than "ticket Petersburg Moscow". The entire Russian Internet waited for such an operator and we could not miss the event. We checked the search volume for approximately 160 millions of our remaining keywords in the new format.
By combining the new operator that makes word order fixed with old "Quotation marks" and "Exclamation point" operators we finally could obtain certain knowledge about actual number of impressions for a specific keyword in a specific form. All our know-hows for selecting more likely forms became totally unnecessary, to much rejoicing on our part. We've sorted our 160 millions of keywords by "[!yearly !search !volume !in !the !new !format]", and selected 80 millions of keywords, which became the foundation of Keys.so database for the Yandex: Moscow region.
For additional regions ( Petersburg, Ekaterinburg, Minsk, Kiev, Rostov-on-Don, Nizhny Novgorod, Krasnodar) we've taken top keywords of our original base, leaving quantities of keywords that we can process in a timely manner. For Petersburg, Minsk and Kiev this number equals 20,000,000, for other regions more than 13,000,000 of keywords. Precise data is always available on our system statistics page
