First of all thanks for all the helpful information in your FAQ and the glossary!
visits= new visits + returning visits
unique visitors = unique new visitors + unique returning visitors
where unique visitors are a subset of all the visits recorded and
new visits are identical to unique new visitors.
I tried to validate whether my assumption regarding the relationship between the different kinds of visits is correct. We use Matomo 4.10.1 to collect user statistics from our website.
“new visits + returning visits” matches the number of visits recorded
“unique new visitors + unique returning visitors” is larger than the number of unique visitors recorded.
