Direct visits to the site and refusals in Yandex.Metrica?

Question

Search Engine Optimization

I have a website with 3 domains.
20 people knock on the main domain every day, visiting time is 0:00.
These visits form a large number of failures (approximately 80%).
The IP block does not help. The source of the transition is not clear.
What could be?

Answer 1

The Chinese are hammering into the ports? :)

Answer 2

Isn't there an advertising campaign for this site by any chance? Competitors don't click with a robot?
By the way, even without an advertising campaign, competitors can use visits with such bad behavioral characteristics to try to lower your site's position in the search results. Although, this is already paranoia))

Answer 3

In the counter settings, enable filtering bots by rules AND behavior. Maybe it will help.
