1. Join a TikTok Trend/Take a Viral Challenge

One of the most popular Duet uses is to join a TikTok trend. Most of the time, this involves following a viral challenge’s instructions to the letter.

This allows content creators to add a personal touch to the video while adhering to a recurring theme. To illustrate this point, @zai1k_ created a Duet video where he sang an original song to a tune set by another user. Fans praised his voice in the video, which received 9.1 million likes.

2. Comments/Responses on Videos

Another popular way to use Duet is to comment or respond to a video. An expert in your niche/field can provide professional insights, fact-check people, or share expert tips.

Choose a video that is already trending on TikTok and gaining a lot of attention. This will increase video views and engagement.

Dr. Shah, also known as @dermdoctor, has 13.6 million TikTok followers. For people to make informed decisions, he regularly creates Duet videos to provide expert input on viral skincare “tips”. For example, he made a “DermDoctor Warns” Duet, warning users not to try a TikTok-famous “pimple hack”.

3. Making Reaction Videos

The Duet feature makes it easier than ever to create reaction videos on TikTok. In this video, people try out your products, tips, and challenges. This is a great way to keep your viewers engaged and entertained.

4. Plan with a co-creator

The Duet feature was designed for collaboration, so use it. Use this tool’s split-screen format to create a video that complements another creator’s video. You could sing along, act out scenes, or even pretend to converse with them.

TikTok user @saraechegaray did just that with actor Chris Barnett’s original vintage acting challenge clip. In a Duet, the user pretends to act out a scene with the original creator. The video received 5.5 million likes, and the user’s acting skills were lauded in the comments.

5. Reshare Your Popular Videos

You can also Duet with your own videos. In other words, you can use the feature to recycle old videos. Using the previous video’s success as a springboard for new content and engagement. You could comment on the previous video, remake it, or even add new ideas/tips to the content.

6. Thank Your Biggest Fans

Duet also allows you to spotlight your fans. Do a Duet with your fans, especially if they specifically mentioned you in the original video. Charli D’Amelio did exactly this when a fan requested a Duet.

7. Prove Your Talent

Showcase your talent is another great way to use Duet. To show off your skills, choose a video you like and add to it. Ideally, use a popular TikTok video to boost your content’s visibility.

8. Predict the End of Another Video

Make your TikTok videos fun and engaging by turning them into games. Create a game by guessing the outcome of the original video. Look for a video that has enough buildup that you can guess what will happen at the end.
