Frequently asked questions
Why does the first 30 seconds matter so much?+
The opening hook is when viewer drop-off is highest — YouTube's own data shows retention falls fastest in the first minute. A strong hook signals to the algorithm that your content is worth showing more widely, because it keeps click-throughs from turning into immediate exits.
What does the grade actually measure?+
The grader evaluates the first 30 seconds of captions for the elements that correlate with retention: how quickly the core value proposition is stated, whether a pattern-interrupt or curiosity gap is created, and whether the viewer is given a reason to stay rather than a reason to leave.
Can I use this to grade other creators' hooks?+
Yes — paste any public video URL. Studying how successful channels in your niche open their videos is one of the most practical ways to improve your own openings.
Will it rewrite my hook for me?+
The grader returns specific, targeted suggestions — the "why" behind each weakness — so you can decide how to rework it. If you want a complete short-form script, pair it with the [Shorts Script Generator](https://veridive.com/tools/shorts-script).
Is the hook grader free?+
Yes — completely free, no account, no sign-up. Grade as many videos as you like.
Do I need an extension or account?+
Neither — it's a web tool. Paste a URL on desktop or mobile; nothing to install.
Does it work without captions?+
It reads the first 30 seconds of the caption track to analyze the hook. Videos with no captions or captions disabled can't be graded. Auto-generated captions are fine.
What counts as a "good" score?+
The scale and benchmarks are shown in the results, but a strong hook generally delivers the video's core promise within the first 15 seconds and creates a reason to keep watching before the 30-second mark. Most videos have room to improve on at least one dimension.
How do I use this with the Shorts Script Generator?+
Grade an existing video to identify its weak points, then use the [Shorts Script Generator](https://veridive.com/tools/shorts-script) to extract the most clip-worthy moments — starting with a strong hook — for a repurposed Short.
Can veridive show me which hook patterns win in my niche?+
Yes — [veridive](https://veridive.com) maps attention patterns across thousands of videos, so you can see what opening structures consistently drive retention in your specific niche rather than guessing.
