A cloud-based web-security service, Incapsula, observed 1.45 billion visits within 90 days period from 20,000 sites that cover the world's 249 countries.
The report concluded that in 61.5 percent of all website traffic in 2013 comes from non-human visitors. a 21 percent growth in total bot traffic since 2012. Bot traffic has eclipsed human traffic for the first time.
While the "good bots" has proven themselves to be useful, especially for webmasters and search engines, "bad bots" on the other hand, can have malicious purposes.
The extra visits put website operators and hosting providers under more strain.
