The tool is really powerful. It simultaneously collects keywords with frequency from both Yandex Direct and Wordstat. For example, if you only use Wordstat, it can find 1,000 words. However, this service additionally gathers suggestions for all phrases and eliminates duplicates. Moreover, the extraction from Wordstat is deeper: it first collects first-level queries, and then for each phrase, it finds extensions. As a result, you end up with about 1.5 times more queries. The system has three main tools. The first one collects all keywords with overall frequency. The second is for analyzing frequency by regions. You can enter phrases manually or import them while specifying the region. The third tool is for gathering suggestions from Yandex that correspond to the original phrases. Access to the service is free, but there is a limit of 10,000 phrases. Using the service without restrictions is not that easy, as each account is verified via SMS, but if you want, you can find workarounds. If you consider the paid option, the price is quite reasonable. The fee is charged based on volume, not time. I can purchase 50,000 queries and use them anytime. When working on a paid plan, it’s more beneficial to choose the more expensive option: there, one query costs only 1 kopeck, and additionally, they provide promo codes for various useful services like Roistat, PublBox, and others.
