Can I change the traffic allocation between variations?
Yes, you can fully customize the ratio of how often a certain variation should be selected compared to your other variations.
Say you have three variations « Blue », « Red » and « Green » plus the « Original » version. By default, Matomo (Piwik) allocates 25% of your traffic to each variation. You may also choose to allocate more traffic to « Blue » and « Red » while your « Green » and the « Original » version gets less traffic.
