Using Google Analytics, in the past week we've noticed an extremely high percentage of people visiting our pages and leaving after less than one second. In some cases they are leaving after zero seconds...
Anyone versed in today's SEO knows that Google track's the "time on site" statistic and uses that to help determine their rankings in search.
What we think is happening is that a competitor might be doing this intentionally. Setting up CURL scripts or something to continuously visit a site and leave immediately, thus hopefully lowering our search rankings eventually. Perhaps they are doing it from multiple IP addresses, we can't tell using Google Analytics (or can we?).
Has anyone heard of this type of behavior? Is there a specific name for it? How do you combat it?
We've been considering tracking the time-on-site using
window.unload and then recording the visited time along with the IP address in order to determine the IP addresses that are causing the problems.
