Since they are listed separately, it means that the meanings of these two representatives are definitely different, otherwise it is meaningless to list them separately.

Yesterday's total visitors are definitely less than yesterday's total traffic, because if a visitor visits one of your treasures, your total visitors are the same as yesterday's total traffic, but in actual visits and browsing, a visitor will look at at at least one of your treasures, so yesterday's total traffic is definitely greater than yesterday's total visitors. In addition, a visitor may visit your same treasure in different time periods, and then the final draft will also lead to the total traffic being greater than the total visitors.
