Very little additional work is required. To get the most from your data, I recommend noting the number of visitors daily – preferably in a spreadsheet – and to use these figures to present and evaluate the amount of traffic – day by day, week by week, month by month, and year by year.
Such data – which statisticians call time series – help us see the fluctuations in traffic. The number of visitors often follow typical patterns through the week and through the year.
Such data also make it easier to observe the relationship between visits and external events: a local festival, a national election, a big sports event, a sudden heat wave, and so on.
