You spend hours perfecting your YouTube videos, but your end screens feel like an afterthought. Your subscriber count barely budges despite quality content, and you know those final 20 seconds could be the difference between a viewer clicking "subscribe" or scrolling away forever. Sound familiar?
These 13 battle-tested prompts transform your end screens from generic placeholders into subscriber-converting machines. You'll get everything from A/B test frameworks and mobile-optimized CTAs to analytics queries that measure real impact on your channel growth. Instead of guessing what works, you'll have copy-ready templates, precise timing strategies, and data-driven approaches that turn casual viewers into loyal subscribers.

3 Concise CTA Variants for End Screen
You are helping {channelName}. For the video titled "{videoTitle}" (length {videoLength}), generate three end-screen CTA variants (each 8–15 seconds) that combine spoken script and exact on-screen text. Include tone (friendly/urgent/authoritative), suggested host gestures, and suggested end-screen button labels. Keep spoken lines under 25 words each.
Generate three short spoken and on-screen CTA scripts tailored to a specific channel and video goal (subscribe, watch next, playlist).
2
End-Screen Layout + Timing Plan
Create a precise end-screen layout for a {videoLength}-minute video aimed at maximizing subscribers. Specify element types (subscribe hotspot, suggested video, playlist), pixel-safe zones, exact timestamps to appear/disappear (mm:ss), visual hierarchy, and 3-second entry animation recommendations.
A concrete end-screen layout with element placement and exact show/hide timings based on video length.
3
A/B Test Variants for End-Screen
Design four distinct A/B test variants for an end-screen for {channelName} whose primary goal is new subscribers. For each variant provide: hypothesis, exact changes (CTA text, button labels, thumbnail size/position, animation), sample implementation steps, required sample size, duration, and primary/secondary metrics to track.
Produce 4 A/B test variants with measurable hypotheses and required metrics to determine the best end-screen setup.
4
Host Script to Match End Screen Visuals
Write a 12–18 second host script for the last 15 seconds of "{videoTitle}" that aligns with on-screen elements: subscribe hotspot (lower-left), two suggested videos (lower-right), and a playlist (top-right). Add stage directions (gestures, eye line) and exact words to appear as on-screen text lines in 2–4 words each.
Write a concise spoken script timed to the end-screen appearance, coordinating exact spoken words with visual cues.
5
Mobile-First On-Screen Text & Character Limits
Provide five mobile-first on-screen text options for end screens (subscribe CTA, suggested video label, playlist label). For each option include a version at 20, 30, and 40 character limits, recommended font weight/size ratio, and contrast color pair (hex codes).
Produce short on-screen texts optimized for mobile visibility and legibility with character limits and font-size guidance.
6
Localized CTAs for Top 5 Markets
Translate and adapt the subscribe CTA and two suggested video labels into the channel's top five markets: US (English), Mexico (Spanish), Brazil (Portuguese), Japan (Japanese), Germany (German). For each locale give: 1) spoken CTA (<=20 words), 2) on-screen text (<=30 characters), and 3) cultural note if wording should change.
Provide translated, short CTAs and on-screen text optimized for those markets and character limits for mobile.
7
End-Screen Graphics + Animation Spec
Create a graphics spec for an end-screen package: subscribe badge, two thumbnail frames, and a playlist card. For each asset provide file format, recommended pixel dimensions (for 16:9), safe zone margins, animation type, easing curve (e.g., cubic-bezier), duration, and example hex colors.
Provide exact visual specs for end-screen graphics including safe-zone PNG sizes, animation easing and duration, and color palettes.
