There is absolutely nothing for you to worry about. Yes, our bots really visit websites without doing anything. They neither click banners or links nor fill in registration forms. But it does not mean that these visits will add to the bounce rate.The point is that modern web analytics systems are advanced enough to easily tell bots from real visitors. If a real user leaves your website after spending there less than 10 seconds this will definitely cause rise in the bounce rate. Technical robots including Semalt ones are not indexed by web analytics systems.
