how can you know if the traffic that come to your website are bots? is it possible to know this via google analytics?
You can not track bots traffic from your Google Analytics account.. To track bots traffic, you need to check your log files in your website cPanel..
It all depends upon the nature of their analytics account access, as some of the anlytics application provide you an option to make your analytics access details public, so that one can see the traffic details..however, in general, no one would like to show his traffic details to someone else..
