Facebook gives you notification when someone likes your page, but there is nothing when someone unlike your page and goes away.
Now with Facebook insight, you can easily track when and how many have unliked your page. This is how,
- Go to your Facebook page and click ‘Insights’ tab at the left.
- On click, 3 new tabs displayed below it. Click ‘Likes’ and proceed.
- Now, navigate down to see ‘Where Your Likes Came From’ section. Here, you’ll see a graph showing per day updates on who liked and unliked your page.
- By default, you’ll see both likes and unlikes stats in khaki and blue colored lines, respectively.
For viewing only the unlikes, uncheck ‘New Likes’ checkbox.
