How to Pick a Winner from YouTube Comments

Why YouTube giveaways need extra care

Running a giveaway under a video is popular because viewers are already commenting. But YouTube publishes contest policies and guidelines, and they place the responsibility on the person running the contest. According to those guidelines, the creator is solely responsible for the contest, for its official rules and for meeting the legal requirements of their jurisdiction.

That makes preparation more important than the draw itself. The random selection takes seconds; the rules, the list and the follow-up are what decide whether your giveaway is handled well.

If you are unsure whether your plan fits the policy, it is better to adjust the plan than to hope nobody notices. Creators who follow their own published rules closely have far fewer problems.

What YouTube’s guidelines ask for

YouTube’s published contest policy lists several expectations for creators. At the time of writing, these include keeping the contest free to enter, publishing official rules, stating that YouTube is not a sponsor and asking entrants to release YouTube from liability, including a privacy notice and running the contest and awarding prizes exactly as the rules describe.

The same policy also prohibits some things, such as running a contest through ad units, asking entrants to give up all rights to their entry, or manipulating metrics like views, likes or subscribers. Policies change, so read the current version on YouTube’s help pages before you launch rather than relying on a summary, including this one.

Write the rules and the entry method

For a comment-based contest, the entry method is usually one comment under a specific video. State in the video, the description or a pinned comment what viewers should write, when entries close, how many winners there will be and what the prize is. Mention who may not enter and where the prize can be delivered.

Keep the condition simple. “Leave one comment answering the question in this video” is easy to check. A long chain of conditions makes it harder to see who qualified and creates more room for complaints after the draw.

If you run several videos in a series, say which video the giveaway belongs to, so that comments left elsewhere are not mixed into the list.

Collect the comments

A comment picker draws from text that you provide. The tool described here does not read YouTube for you, so you copy the commenters’ display names, or the comments themselves, and paste them into the picker with one entry per line. On a video with many comments, you may need to scroll through the whole thread so that everything is loaded before you copy.

Decide beforehand whether replies count. A reply to another viewer’s comment is a different thing from a top-level comment, and treating them differently without saying so is a common source of confusion. Also remember that display names can be identical or changed, so keep a note of the closing time at which you collected the list.

Clean the list and handle duplicates

Before drawing, remove anything that does not meet your rules. That includes comments posted after the closing time, your own comments, entries from people who are excluded, and obvious spam. If your rules allow one entry per person, use duplicate removal so a viewer who commented three times has only one chance.

If you want to give more chances for extra actions, such as commenting on several videos, spell out how they are counted. Fewer moving parts make the draw easier to explain, and easier to defend if someone asks questions.

Run the draw and show your work

Choose the number of winners and run the draw once. The picker shuffles the list using the browser’s cryptographic random number generator, so the result cannot be steered. If your video is a live stream or premiere, you could run the draw on camera; otherwise a short screen recording of the paste, the entry count and the result works well.

Announce the result in a pinned comment or a community post, and consider drawing one or two reserve names for the case that a winner does not reply. Reply to the winner using the contact method named in your rules, and be careful about impostors who copy announcements to scam viewers.

It is also good practice to say in the announcement that the contest is not sponsored or endorsed by YouTube, as the platform’s guidelines ask hosts to make clear.

Protect your viewers’ data

YouTube’s guidelines expect a privacy notice explaining how personal data collected for a contest will be used. Even a simple giveaway involves usernames and perhaps a postal address for the prize, so decide what you need and delete it when it is no longer necessary.

Collect an address only from the winner, and only after they are confirmed. The picker itself keeps the list in your browser and does not upload it, which means you decide how long it exists. As always, this is general information and not legal advice; laws on prize draws and data protection differ between countries, so check what applies to you.
