If you have a business Facebook page, as of 12th March 2015, you may notice a dip in the amount of people who ‘like’ your page.
Facebook is no longer going to count likes from users who have deactivated their accounts or passed away. Claiming in a blog post that these changes will offer businesses a clearer, more accurate idea of their audience.
If users who have deactivated their account reactivate it then that action will be tallied back into the total like count.
“Going forward, any accounts that are voluntarily deactivated or memorialized will be removed from a Page’s like count. If a deactivated account is reactivated, the account will be re-added to a Page’s like count. Everyone benefits from meaningful information on Facebook. It’s our hope that this update makes Pages even more valuable for business.” – Facebook
