How to deal with traffic cheating (bots) on your site?

Question

Yandex.Metrica

Good afternoon. In the last month, my site has been actively visited by robots, visits to the main page for certain requests, it doesn’t look like a DDoS attack, Yandex Metrica records visits to robots in the “ROBOTS” report, they are present in all reports. In the webvisor, it records their attendance for up to 30 seconds on the site, when they enter the site page, their mouse arrow frantically twitches for 30 seconds and then they leave the site. The statistics shows that the transitions were made from various search engines for various queries, the most interesting thing is that the queries relate to the subject of my site, although I have nothing to do with this. The approximate number of visited bots per day is somewhere up to 800-900 from all over the world, with its actual attendance of 130-150 people. Per day.
Also on the site installed statistics liveinternet.ru, it fixed the falsification of statistics, and showed only the actual attendance.
Initially, I thought that it was temporary and did not take any action, then I noticed that the robots were not going to leave my site. I made a regional distribution so that visitors to my site could only come from the region to which the site belongs. This helped, but not as much as we would like, anyway, 200-300 bots per day visited the site. Then I dug into the Yandex metrics and set the filter item “filter robots according to strict rules and behavior”, this also helped, well, anyway, 20-30 robots a day slip into the statistics. And in the reports, "Robots" captures those robots that got to the site but did not get into the statistics of 100-130 per day.
Please tell me what measures I can still take to expel these slaves from the site completely.

bots are an integral part of the modern Internet, they load heavily - rebuild algorithms
