Understand Traffic Distribution
"Traffic Distribution", relates to what percentage of your visitor traffic you are going to put through your experiment.
So, let say that you allocate 40% of traffic to your experiment and you have the original and one variation more. 20% of visitors will be shown the original, 20% will be shown the 1st variation. Statistics and goal conversions will be gathered on this 40%.
The rest of the 60% of visitors will be shown the original without collecting any statistics on them.
To change the traffic distribution value go to your "Experiment Summary", and edit the "Settings" section.
Then a modal will open which show different settings including the traffic allocation.
