A strong video hook is essential for capturing and maintaining viewer attention. Here's a breakdown of what makes a hook effective, according to the sources:

Continuity of Packaging

A hook must be a direct continuation of the video's title and thumbnail, rewarding the viewer for clicking and creating a cohesive experience. The hook should seamlessly follow the "packaging," which refers to the thumbnail and title.

Elicit Questions

Rather than providing answers, a strong hook should prompt further questions and curiosity, compelling the viewer to keep watching.

Part of a Whole

The hook is not a standalone element but a critical piece of the video that must fit with the rest of the content.

Attention Span

Hooks must be concise, as the average viewer's attention span is about 8 seconds.

Make it simple

Manage the amount of mental effort required to process the information in the hook to avoid overwhelming viewers. Make the content easy to understand even for a kid.

Curiosity

A good hook provokes curiosity, making the viewer want to learn more.

Reward the Click

The hook needs to reward the viewer for clicking on the video.

Clear Value Proposition

State clearly what the viewer will gain from watching, whether it is new information, entertainment, or a solution to a problem.

Strong Opening

Begin with something attention-grabbing, such as an intriguing question, surprising fact, or bold statement.

Cliffhangers

Use cliffhangers, questions, challenges, or incomplete information to keep viewers engaged.

Authenticity

Being genuine and letting your true personality come through can be a strong hook.

Reinforce the Click

Remind viewers why they clicked on the video to maintain their interest.

Techniques
-Start with the "when" Because "how" often requires more context, starting with "when" can help optimize the hook.
-Presenting a narrative of underdogs can draw viewers in.
-Authority Reinforcement. Show, don't just tell, that the story is real.
-Subtle art of managing attention. In the first seconds, the goal is to provoke curiosity to stabilize the attention
-Use a pause. Use pauses to allow the viewer to digest the information

What to Avoid
-Half-Answers. Hooks should not provide half-answers, but should elicit more questions.
-Overwhelming Viewers. Do not overwhelm the viewer's cognitive load
-Vague Advice. Avoid vague advice that doesn't provide a solid structure
-Mistakes. Mistakes in the hook can significantly cost you attention
