According to Incapsula, bot traffic has heavily increased in 2013. Bot traffic accounted for around 61.5% of all website traffic. Around 31% of bot traffic is from legitimate sources like search engines crawling the web to index content though. Hacking tools and spammers did not see major jumps this year, but malicious intent (like impersonators) were up 8%.
“The most plausible explanation for this steep decrease is Google’s anti-spam campaign, which includes the recent Penguin 2.0 and 2.1 updates,” stated Incapsula. The Penguin 2.0 and 2.1 updates are in reference to Google upgrading their search algorithms.
“SEO link building was always a major motivation for automated link spamming. With its latest Penguin updates Google managed to increase the perceivable risk for comment spamming SEO techniques, while also driving down their actual effectiveness,” added Incapsula. Google was able to create a 75% decrease in automated link-spamming activity as a result of their search algorithm changes.
The 8% increase in “impersonators” now brings that category to 20.5% of web traffic. That group is made of unclassified bots that have “hostile intensions.” This group of bots attempt to steal someone else’s identity. Impersonators can be automated spy bots and human-like DDoS agents.
