Giveaways are promotional campaigns run by creators or brands in which prizes are offered to audience members who complete specific actions — such as subscribing, commenting, liking, or sharing a video. On YouTube, giveaways are used as a growth hacking tactic to rapidly increase engagement, followers, and reach. While they can generate short-term spikes in subscribers and comments, their long-term effectiveness depends on attracting genuine engagement from viewers who are actually interested in the channel’s content rather than just the prize.
