How to pick a random winner from Facebook comments

Facebook has no built-in way to pick a giveaway winner, and long comment threads are impossible to count by hand. Here is how to load every comment of a Facebook post, filter them with your rules, draw the winner fairly, and show everyone the result was random.

ステップごとの手順

Install Giveaway Picker. Add the extension to Chrome, Edge or Brave and pin it.
Open the Facebook post. Open the post on its own page (click its date) while logged in, then click the extension icon and "Load comments".
Set the rules. Choose one entry per person, a required keyword, the deadline and the accounts to exclude, such as your page and your team.
Draw and share. Click "Draw the winner", then share the certificate link and the winner image with its QR code.

Facebook’s rules for giveaways on Pages

Facebook’s Pages terms don’t allow promotions that require people to share on their timeline or tag friends to enter. "Comment to enter", or "comment with a word", is fine. So on Facebook, use a keyword or simply one entry per person rather than a tag requirement.

As the host you are responsible for the official rules, the prize and local laws, and for saying the promotion is not sponsored by Facebook.

Combine Facebook and Instagram in one giveaway

Running the same giveaway on both? With Pro, select your Facebook post and your Instagram post in the same giveaway. People are counted per account on each platform. Choose "one entry per post commented on" to reward people who took part on both.

A draw your community can check

The entrant list is locked and fingerprinted before a public random number exists (drand, League of Entropy). The winner is computed from it, and the certificate lets anyone redo the calculation in their browser. Redraws are listed with their reason, so nobody can quietly draw until a friend wins.
