Facebook provides measurement tracking in the “Insights” section of your Business Page and every week Facebook emails the Daily Tracking for the week. These statistics are helpful, but unless you continually track the data and not just the snapshot of the data the day you look at the statistics it really does not mean much.
There will be days when no one visits your Page, days when no one comments.
Compare it to a Yellow Pages ad in the printed book, your ad is printed and located in the section for your industry, however consumers are not looking at the Yellow Pages every day. If there was a way to track Yellow Pages views the arrows would most likely point down for the majority of the weeks. Consumers crack open a Yellow Pages when they need a service. Facebook has your Business Page and all information up 24/7, post to that page weekly and your business is being seen on a weekly basis not just when someone needs what you do. Whether or not people are clicking on your Page or Commenting on your posts, they see you and know you are there.
