We see a 21% growth in total bot traffic, which now represents 61.5% of website visitors. The bulk of that growth is attributed to increased visits by good bots (i.e., certified agents of legitimate software, such as search engines) whose presence increased from 20% to 31% in 2013.
31% of Bots Are Still Malicious, but with Much Fewer Spammers
While the relative percentage of malicious bots remains unchanged, there is a noticeable reduction in Spam Bot activity, which decreased from 2% in 2012 to 0.5% in 2013. 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.
Nice infographic with a focus on telling one story really well.
