How it works?
The first time a user visits a page he gets an experiment assigned. The experiment's ID is stored in the user's cookies. He will not get other experiments assigned until the one he's on is active.
How is the traffic allocated between experiments? By default, the traffic is divided equally between all experiments. If some experiment has to have more or less traffic, it can be specified through the traffic parameter. The value of traffic has to be between 0 and 1. 0 is no traffic at all. 1 is 100% of the traffic.
How to target specific devices/pages/users with an experiment? An experiment will only be assigned to a user if its assignment condition is satisfied. The assignment condition is a function passed to the ac property that returns a boolean. So if an experiment is changing the homepage for mobile devices, the AC of the experiment can look like this:
{return locationhref !== -1 &&matches;}
Usage example
;
