Explainer Script Checklist: Hook, Promise, Proof, and CTA in Under 60 Seconds To write an effective explainer script that fits within a 60-second time frame, you need to focus on creating a clear and concise narrative that hooks your audience, promises a solution, provides proof, and ends with a call-to-action (CTA). This checklist will guide you through the process of crafting a script that maps cleanly onto storyboard clips for Reels, Shorts, and TikTok, ensuring your message is delivered efficiently and effectively.
What Makes a Strong Explainer Script? A strong explainer script is one that balances engagement with information, ensuring that the viewer is both entertained and educated within a very short time frame. It must be able to capture attention from the start, maintain it through the presentation of a solution or teach, and then encourage the viewer to take a specific action. This is achieved by carefully structuring the script into several key sections: the hook, the promise, the proof or steps, a recap, and finally, the CTA.
Structuring Your Explainer Script | Section | Purpose | Approx. Time | |--------|---------|--------------| | Hook | Grab attention | 3–5s | | Promise | Introduce the solution | 3–5s | | Proof/Steps | Deliver the value | 25–40s | | Recap | Summarize the key points | 3–5s | | CTA | Encourage action | 3–5s |
1. Crafting a Compelling Hook - [ ] Identifies a problem or question the audience is concerned about. - [ ] Avoids generic or vague statements. - [ ] Aligns with the promise that follows. - [ ] Works well as on-screen text if the video is muted. - [ ] Can be visualized in a single, clear frame.
Effective Hook Examples: - "Are you tired of manually tracking your expenses?" - "Want to learn how to create engaging social media content in minutes?"
2. Making a Clear Promise - [ ] Clearly states what the viewer will learn or achieve. - [ ] Is specific and achievable within the video's runtime. - [ ] Uses language familiar to the audience. - [ ] Sets the expectation for what kind of proof or steps will follow.
Example of a Strong Promise: - "In the next minute, you'll learn how to simplify your expense reporting process."
3. Providing Convincing Proof or Steps - [ ] Limits the number of steps to 2–5 for a sub-60s video. - [ ] Each step is a actionable verb the viewer can repeat. - [ ] Follows a logical order that mirrors real workflow. - [ ] Uses concrete examples. - [ ] Avoids steps that rely on unsubstantiated claims.
Line-Level Craft Tips - Prefer short, direct sentences. - Remove unnecessary phrases or words. - Place key nouns early in the sentence. - Use one number per sentence when possible.
4. Recap: Reinforcing the Message - [ ] Reiterates the promise using similar vocabulary. - [ ] Fits on a single caption card. - [ ] Doesn't introduce new information.
5. CTA: Encouraging Action - [ ] Makes a single, clear ask. - [ ] Aligns with the teach or solution presented. - [ ] Is appropriate for the context (educational or promotional). - [ ] Matches the on-screen CTA.
A Worked Example: Simplifying Expense Reporting Let's say we're creating a 45-second explainer video on simplifying expense reporting. Here's how the script might look:
Hook: "Tired of spreadsheets for expense tracking?" Promise: "Learn how to simplify your expense reporting in three easy steps." Step 1: "First, centralize your receipts." Step 2: "Next, automate your expense categorization." Step 3: "Finally, generate your report with one click." Recap: "Simplify expense reporting in three steps." CTA: "Try our expense tracking tool today."
A Second Worked Example: Creating Engaging Social Media Content For a 50-second explainer video on creating engaging social media content, the script could be structured as follows:
Hook: "Want to boost your social media engagement?" Promise: "Learn how to create engaging social media posts in four simple steps." Step 1: "First, identify your target audience." Step 2: "Next, craft a compelling headline." Step 3: "Then, add visually appealing graphics." Step 4: "Finally, time your post for maximum visibility." Recap: "Create engaging social media posts in four steps." CTA: "Download our social media content calendar template now."
Decision Table for Script Structure | Script Element | Purpose | Time Allocation | Key Considerations | |---------------|---------|-----------------|--------------------| | Hook | Grab attention | 3–5s | Relevant, concise, and engaging | | Promise | Introduce solution | 3–5s | Clear, specific, and achievable | | Proof/Steps | Deliver value | 25–40s | Logical, actionable, and concise | | Recap | Summarize key points | 3–5s | Brief, consistent with promise | | CTA | Encourage action | 3–5s | Clear, relevant, and actionable |
Failure Modes and Fixes ### Failure Mode 1: Unclear Hook - Symptom: Viewers are not engaged from the start. - Fix: Revise the hook to directly address a problem or question the audience is concerned about. Ensure it is concise, relevant, and can be visualized.
Failure Mode 2: Overly Complex Steps - Symptom: Viewers are confused by the steps or proof provided. - Fix: Simplify the steps by reducing the number and focusing on actionable, easy-to-follow instructions. Use concrete examples to illustrate each step.
Failure Mode 3: Weak CTA - Symptom: Viewers are not encouraged to take action. - Fix: Strengthen the CTA by making it clear, specific, and relevant to the solution or teach presented. Ensure it aligns with the on-screen CTA and is appropriate for the context.
Ship Checklist for Your Explainer Video 1. Script: Written with a clear hook, promise, proof/steps, recap, and CTA. 2. Storyboard: Each line of the script is matched with a visual concept. 3. Voiceover: Recorded and timed to fit the video length. 4. Visuals: Created and implemented according to the storyboard. 5. Edit: The video is edited to ensure a smooth flow and to match the storyboard. 6. Review: The final video is reviewed for quality, accuracy, and engagement. 7. Publish: The video is published on the designated platforms.
Avoiding Common Pitfalls - Feature Lists: Avoid listing features without explaining their benefits. - Biographical Introductions: Skip introducing the founder unless it's directly relevant. - Culturally Dependent Humor: Be cautious with jokes that may not translate across cultures. - Generic CTAs: Ensure the CTA is specific and relevant to the content.
By following this checklist, understanding the structure of an effective explainer script, and avoiding common pitfalls, you can create an engaging and informative explainer video that delivers value and encourages action, all within the challenging but effective 60-second timeframe.
