Facebook Reactions: Meaning, Current UI, and Reporting
Facebook reactions definition: Facebook reactions let people express a more specific response to a Facebook post or comment than a standard Like. A person can add one reaction to each post or comment, then change or remove that reaction later.
Reactions are an interaction on Facebook itself, not a separate post type or a measure of how well content performed. They can give a Page or creator a compact view of how people chose to respond, but they do not explain why someone responded that way or whether they took any action afterward.
How the Facebook reaction picker works
On a computer, go to the post or comment, hover over Like, and choose a reaction from the picker. In the Facebook mobile app, press and hold Like to open the picker. The most common reactions appear as icons beneath the post or comment. Select a different icon to replace your reaction, or remove it if you no longer want to react.
The current picker includes Like, Love, Care, Haha, Wow, Sad, and Angry. The controls and their placement can vary by device and Facebook surface, so use the in-product picker rather than relying on an older screenshot or a fixed button location.
What reactions can and cannot tell you
A reaction count records a selected response. It is useful alongside comments, shares, clicks, video views, or other metrics that fit the content and reporting question. It is not a sentiment analysis: for example, a Haha, Wow, or Angry reaction has no single meaning outside the post and the surrounding conversation.
For Page reporting, compare reactions with the post context and the time period you are reviewing. Do not treat one reaction type as proof of positive or negative audience sentiment, and do not infer business outcomes from reaction totals alone.
Official Meta source
Meta's Facebook Help Center guidance on reacting to posts and comments confirms that reactions can be added to posts and comments, that one reaction can be added to each item, and that reactions can be changed or removed.
