TikTok has become the most effective platform for product promotion and brand building today. With millions of active users daily, it's an ideal place for businesses, KOLs, and content creators to reach potential customers. However, to create a truly viral advertising video, you need to master content formats that suit the characteristics of TikTok users' behavior: concise, eye-catching, emotional, and entertaining.
This article will introduce 10 video advertising ideas with strong viral potential, along with detailed explanations to help you easily implement them.
1. Before/After Transformation
Define: This type of video clearly shows the changes in a user's appearance, state, or emotions before and after using a product or service. The Before-After Transformation trend is one of the hottest video types on TikTok, featuring creative transition effects that showcase dramatic changes, such as a complete makeover, makeup transformation, or humorous "before and after" moments.
Why it works: TikTok users love dramatic transformations. The more striking the contrast, the more it attracts viewers to stop and watch the entire video.
For example: Before use: acne-prone skin, poor lighting, sad expression. After use: smooth skin, confident demeanor, radiant glow.
Suitable for: Cosmetics, spa services, weight loss, fashion, interior design.

The "Made You Look" transformation trend: Vietnamese TikToker Quynh Thi has become a phenomenon with her "Made You Look" transformation video, which has garnered over 75 million views and 8.5 million likes. Her video features impressive style and makeup changes, leading many to imitate her look.
2. 7-Day Challenge
Define: This is a series of videos documenting the journey of using a product or changing habits over 7 consecutive days.
Why it works: Viewers are often drawn to timed challenges because they want to know the final outcome. Breaking it down over several days helps retain viewers and increase followers.
For example: “"I drank this detox juice every morning for 7 days and this is what happened to my body."”
Suitable for: Health products, skincare, diet, learning apps, fitness and sports.

3. Funny Videos – Unexpected Ending
Define: This type of content combines comedic elements with a plot twist, often leaving viewers either laughing or surprised.
Why it works: Humorous and entertaining content has a very high potential for going viral because viewers will share it with friends or save it to watch again later. A surprise element at the end of the video will help increase watch time and engagement.
For example: A guy was rejected for a date because of his body odor, then used deodorant X and became unexpectedly attractive.
Suitable for: Personal care products, services, entertainment apps, fast food.
4. First-Time Reaction to the Product
Define: Recreate the natural (or staged as natural) reaction of a user when first trying a product or service.
Why it works: "First-time reaction" videos often make viewers feel a sense of authenticity and trust in the product. Genuine emotions are a key factor in motivating users to take action.
For example: A person trying a new juice flavor for the first time shows a surprised and delighted expression.
Suitable for: Food, beverages, cosmetics, handmade products.

5. Use cute children or elderly people.
Define: For people outside the target customer group, use the product skillfully, endearingly, or humorously.
Why it works: Seeing elderly people or young children using a product "pro" is often surprising, interesting, and easily creates a viral effect.
For example: An 80-year-old man plays mobile games or reviews cosmetics in a humorous tone.
Suitable for: Games, educational apps, household products, technology.
6. Combining Effects + Trending Music
Define: Utilize the trending effects, filters, and background music on TikTok to create trending videos.
Why it works: TikTok often prioritizes videos that use trending effects and music. Therefore, by cleverly incorporating these elements into your advertising content, you can increase your chances of going viral.
For example: Using an "aging" filter combined with the song "School Days" to promote an anti-aging product.
Suitable for: Fashion brands, cosmetics, technology applications, innovative products.
7. Comparing Yes and No
Define: Demonstrates a clear difference between having and not having the product/service.
Why it works: Direct comparison content helps viewers quickly understand the value of a product. If presented in a fun way, the video is even more likely to go viral.
For example: Without a vocabulary learning app: "Apple is… I forgot what it is." With an app: "Apple – an apple. Banana – a banana."“
Suitable for: Applications, support tools, utility software, household appliances.
8. ASMR or Satisfying Videos
Define: Videos that focus on visually and aurally pleasing sound and images often create a relaxing or exciting viewing experience.
Why it works: ASMR is a global trend, with viewers often lingering longer on videos featuring pleasant sounds or visually appealing, repetitive imagery.
For example: Shampooing hair, facial massage, baking, typing on a mechanical keyboard, spraying perfume.
Suitable for: Hair salon, spa, food, skincare, designer products.

9. Emotional Storytelling
Define: Short videos tell a touching, humane story, often linked to a message or product.
Why it works: Videos that resonate with viewers' emotions – such as family love, sacrifice, kindness – are more likely to be shared, commented on, and spread naturally.
For example: The father, a delivery driver, always came home late, but he never forgot to bring milk for his little daughter.
Suitable for: Food, household products, insurance, inspiring brands.
10. Mini-Series Video Set
Define: Create continuous content in a sequence (e.g., Day 1, Day 2, Day 3…), with each video representing a part of the journey.
Why it works: Mini-series help increase watch time, gain followers, and keep viewers engaged for longer. Each video should have a strong hook at the beginning and an open ending to encourage further viewing.
For example: “"My 14-day journey learning Korean with app X," "I tried living without sugar for 5 days – this is the result."”
Suitable for: Healthcare products, learning apps, fitness, lifestyle.
