After the work of "experienced" optimizers, our site fell under Yandex's AGS, and our positions almost completely disappeared, along with our clients who bring in profit. The boss "rang the alarm bells." We started searching for a "savior" in emergency mode. On the recommendation of friends, we found Webexpert, who identified the problem within a day. In 3 weeks, they restored our site's positions.
It turned out to be a crazy month for us! We wish you good luck, profits, and great clients (at least as good as ours). High-class professionals. We recommend them!
