When selecting a time range in EzyInsights, from 1 hour to a whole week, it's important to understand what the tool is showing you.
When choosing stories to show in your date range limited view, Ezy will look at all instances of the article being shared, including via RSS feeds on websites. So an article with a publish date outside of the range you've selected may show if the article in question has been endorsed or updated via a recent RSS push.
If you are specifically interested in seeing what a given Facebook page has published within a given time frame, be sure to select 'Only Posted' on Facebook in the filter options menu on the left hand side.
This will give you a view showing only Facebook posts made on the selected page(s) within the selected time frame.
