The visit counter on the homepage counts only the visits of the homepage, but not
the visits of other pages. It filters the duplicates over a day and multiple visits
from one unique visitor over a day / 24 hours is counted as one visit.
If someone enters the site via any other page without visiting the homepage, this
visit counter won’t record this particular visit. I’m sure there are more sophisticated
counter tools out there, but this one comes with the Serif (Site Builder) package
and was easy to implement.
