If your site includes Facebook “like” buttons to encourage people to share your content, be careful about how you use those numbers — or how seriously you take them.
Clint Watson writes inÂ Â Facebook Like Button Count Inaccuracies:
The Facebook “like” buttons you see embedded on websites incorrectly report the number of “people” who “like” something. Specifically, the button can inflate the displayed count of people.Â While this is fine when all you want to do is track some general level of “engagement” with a particular item, it was not accurate for the use I needed – counting each “like” as a vote in our BoldBrush Online painting competition.
What I needed is a way to get the number of actual people who “like” something.Â And there is a way to retreive that information from Facebook, but it is often a different number from what is shown on the “like” button itself.
If you are a geek – here’s the bottom line of this post:
If you’re using the Facebook “Like” Button Social Plugin and you need an accurate count of the actual number of people who have clicked the “like” button, you can’t rely on the number reported by the button itself.Â You need to retrieve your URL’s “fan count” number via Facebook’s Open Graph API.
Hat tip to Zach Seward for bringing this to my attention.
