Visits
Facebook also shows interesting details about visits by dividing
the flap into two smaller charts: "Visits to the page and guides"
and "External references".
In this tab, it shows in detail the number of times each tab or
section of your page was viewed. It also provides information
about external references, that is, a statistic containing the
number of people who found your page from a site outside of
Facebook.
Page views and guides
Clicking on a specific chart data you have access to the number
of times that each tab is displayed on that particular day, and the
percentage that each tab is the total number of hits.
You can see all crossed data on the same chart or define a
specific guide to make the display more
clean. For the latter option, simply click on the chosen tab the
right side of the chart, below which is written reference.
If you notice that a certain section of your page is not receiving
an expected number of hits, you can use this data to try to
increase this rate.
