If you want to run multiple A/B tests that have the same KPI and are on the same audience, you need to set up collision prevention so these projects do not collide and therefor corrupt your data.
You need to do this before you start any of the projects. The first thing you need to do is set the traffic allocation for each project.
SiteGainer evaluates projects in creation order. So you need to set traffic allocation to lower than 100% (total) in the first project to be able to send some of the traffic to the other project.
In the example below we want to run two projects at the same time;
First, open the editor for project 1 (created first of the two). Then click on the Settings button. Choose Traffic allocation.
Then set the traffic allocation for the variants. If you wish the two projects to have equal traffic you want this setting to be a total of 50%.
Then you need to set up the collision prevention in Audience settings for project 2. To do this you need the project ID for project 1. You can see this in the dashboard. Copy this.
Then open the editor for project 2, click on Audience.
Drag and drop a Collision prevention rule and paste the project ID for project 1 in the input field. Then set the dropdown to ”HAS NOT BEEN RUN” and hit Save.
