Global web traffic has increased sharply over the past few years. However, the majority of today's website traffic is not actually human traffic.
Follow up:More than 60% of website traffic can be traced back to bots that automatically browse websites for different purposes. Roughly half of all automated traffic comes from good bots, that search engines such as Google use to index a website’s content. The other half of automated traffic is malicious though, caused by content scrapers, spam bots or and other programs that mean harm.
