How do you structure a script for a 30-second video ad?
, 6 min read
A 30-second video ad script typically follows a three-part structure: a hook, a body, and a close with a call to action. This structure helps convey value and inspire action, aligning with how users consume short-form content. Platforms like TikTok and YouTube Shorts provide specific guidance on how to build these elements effectively for performance.
The short version
- Structure your ad with a hook, a body that highlights unique selling points, and a clear call to action.
- Grab attention in the first 3-6 seconds to maximize ad recall and engagement.
- The ad's body should pull the audience through your story with additive branding cues and solutions.
- End with a strong, benefit-focused call to action that feels like a natural next step for the viewer.
- Use vertical video, sound, and a 'social first' aesthetic, keeping content within the UI safe zone.
What is the basic structure of a short video ad?
A short video ad generally follows a three-part structure: a hook, a body, and a close. This framework is designed to convey value and inspire action efficiently. TikTok, for example, recommends this structure to help advertisers communicate their message effectively.
The 'hook, body, and close' structure is a well-proven content approach that sells. Another straightforward way to structure an ad, particularly for TikTok, is the 'Problem → Solution → Benefit' model. For ads focused on conversion, a 'Quick demo' structure can be highly effective.
Each part plays a distinct role: the hook grabs attention, the body highlights unique selling points and tells your story, and the close seals the deal with a clear call to action.
How do you create an effective hook?
An effective hook is crucial for engaging viewers quickly. TikTok documents that you should prioritize your hook in the first 6 seconds to boost engagement and increase watch time. For even better recall and awareness, introduce your content proposition within the first 3 seconds.
The first few seconds are vital because 90% of ad recall impact is captured within the initial six seconds. To keep your audience's attention, communicate the value proposition of your ad early. Exciting hooks can use techniques like suspense, surprise, or emotion to capture interest immediately.
What should the body of the ad include?
The body of your ad is where you develop your message after the hook. It should highlight your unique selling points, explaining what makes your product or service stand out. This section pulls the audience through your story with additive branding cues, reinforcing your brand's presence and message.
If you are following a 'Problem → Solution → Benefit' structure, the body of the ad is where you present the solution to the problem introduced in the hook. You then detail the benefits of that solution, connecting them directly to the unique aspects of your offering.
How do you write a strong call to action?
A strong call to action (CTA) is essential to guide your audience on what to think, feel, or do next. It should be clear and benefit-focused, making it the obvious next step for the viewer. TikTok advises ending with a strong CTA to seal the deal with customers.
The timing of your CTA can vary by platform and campaign type. For example, Google states that on YouTube Shorts, the CTA button appears 3 seconds into the ad for Performance Max, App, and Demand Gen campaigns. For Video View and Video Reach campaigns, it appears at 10 seconds. Regardless of timing, ensure your CTA is compelling and directly relates to the ad's message.
What are the technical and aesthetic considerations for short video ads?
For short video ads, technical specifications and aesthetic choices significantly impact performance. Both TikTok and Google recommend using vertical video assets. This means an aspect ratio of 9:16, which is taller than it is wide, to fit the mobile-first, full-screen experience of platforms like TikTok and YouTube Shorts.
TikTok emphasizes the importance of keeping your content visible within the UI safe zone. The safe zone is the area of the screen where your content will not be obscured by the platform's user interface elements, such as profile icons, captions, or navigation buttons. TikTok states that being aware of this 'safe space' ensures your creative assets will be more efficient at spending and targeting.
Google recommends using vertical, sound-on assets that feel 'social first' and best deliver your brand message on the mobile device. TikTok suggests a DIY or not overly polished style, fitting in with user-generated content. Sound is vital; 88% of TikTok users say sound is essential to their experience, and Google also recommends sound-on assets. TikTok documents that editing techniques like music, transitions, movement, text overlay, and emojis work best to create interest, capture attention, and drive ad memorability. When using text, TikTok recommends displaying 5-10 words per second for readability.
Regarding length, TikTok finds that videos up to 60 seconds are supported, but 21, 34 seconds performs best. For YouTube Shorts, video ads can be up to 3 minutes long, though only the first 60 seconds will play on the Shorts feed. An overlay appears at 50 seconds, allowing users to watch the rest on the YouTube watch page. Google recommends adding videos under 60 seconds to match user behavior, and 10-30 second vertical videos are suggested for action-oriented ads.
| Platform | Recommended Length | Maximum Length |
|---|---|---|
| TikTok | 21, 34 seconds | 60 seconds |
| YouTube Shorts | Under 60 seconds (10-30s for action-oriented) | 3 minutes (first 60s on feed) |
