Convert allows you to exclude visitors in your experiment that have been included in another one.
To do this you have to configure an Advanced Audience.
- Edit your Audience.
- Create New Audience:
- Select and drag to main panel the "Visitor Data > Visitor Cookie" option. Enter for Cookie Name: "_conv_v". Select: "Does not contain". Enter the experiment id, for which its visitors should be excluded in this experiment, for example "123456789". Save the Audience.Now, the visitors that have been bucketed on the specified experience, won't be bucketed in the one in which you have created the "Advanced Audience".
Note that if trying to exclude visitors that were included on a test configured with less than 100% traffic, a cookie is still written if they met the Site Area and Audience conditions but due to the traffic restriction, were not actually included in that experiment.
The cookie will look similar to this:
Note that there is no variation value - only v.1 - because they were not included in the experiment. However, we still keep track of this with cookies so that next time they visit they will again be excluded from the same experiment with less than 100% of traffic.
In this case, in your audience where you want to exclude people that were part of a particular previous experiment, you could include them if the cookie value DOES contain
This will match only visitors that were considered but rejected for inclusion in the previous experiment (because they fell outside of the percentage of visitors that would be added to that previous experiment).
