The 5-10 Second Hook (Long-Form)

Long-Form Hook Differences

Unlike short-form's 1.3-second rule, long-form allows 5-10 seconds for hooks, but the principles remain:

Hook Components:

1. Pattern Interrupt (0-2 seconds): Stop the scroll
2. Promise (2-5 seconds): What viewer will get
3. Proof/​Preview (5-10 seconds): Why to trust you

Long-Form Hook Templates

Preview Hook: "In this video, I'm going to show you [result]. By the end, you'll know [specific outcome]."

Curiosity Hook: "What I'm about to share changed everything I thought I knew about [topic]..."

Result Hook: [Show the end result] "This is what we're building today, and I'll show you exactly how."

Story Hook: "Three months ago, I made a mistake that cost me [consequence]. Here's what I learned..."

Problem Hook: "If you've ever struggled with [problem], you're not alone. Here's what actually works."

Hook Mistakes to Avoid

• "Hey guys, welcome back to my channel..."
• Long intro animations
• Asking for likes/​subscribes before value
• Generic greetings
• Explaining what you won't cover
