After years of observing Bots vs Browsers by analyzing user agent logs, the struggle appears to have swung heavily in favor of the bots in 2013. As late as 2012, the browsers (humans) were still within 1% of the majority of website traffic, but 2013 saw robot traffic increase with a vengeance.
According to an article published by Incapsula, robots are now responsible for 61.5% of all website traffic.
The study last year measured much closer, at 51% of all website traffic coming from bots.
This pushes human traffic down from 2012 at 49% down to 38.5% in 2013.
As far as the breakdown of what type of robots are responsible for all of this traffic, here is a quick list:
- 31% Search Engines (i.e. the "good" bots)
- 5% Scrapers
- 4.5% Hacking tools
- 0.5% Spammers
- 20.5% Other Impersonators (basically all other non-humans)
