Global web traffic has increased sharply over the past few years. However, the majority of today's website traffic is not actually human traffic.
According to Incapsula's Global Bot Traffic Report, 56% 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, e.g. search engine crawlers that index a website’s content. The other half of automated traffic is malicious though, caused by impersonators, content scrapers or other hacking tools that are used to steal data, spam websites or simply bring them down.
This chart shows that more than half of global website traffic is not caused by humans.
