プラットフォーム別のフック

YouTube（長尺）

More time to build curiosity:
- Can use 5-15 second hooks
- Setup + Payoff preview works well
- Credibility establishment helps

Example:
"In 7 years of [expertise], I've never seen anything like this.
What I'm about to show you completely changed how I [do thing],
and by the end of this video, you'll know exactly how to do it too."

YouTube Shorts／TikTok／Reels

ULTRA-FAST hooks (1-3 seconds):
- First word/frame must hook
- Text on screen essential
- Visual hook + Audio hook together

Example:
[TEXT ON SCREEN: "The $3 thing that replaced my $300 product"]
[VOICEOVER: "Throw away your expensive [product]"]
[VISUAL: Dramatic product reveal or reaction]

Instagram Reels

Slightly more polished feel:
- Aesthetic matters more
- Hook can be visual-first
- Trending audio helps

Example:
[VISUAL: Stunning transformation or result]
[TEXT: "Wait for it..."]
[AUDIO: Trending sound that builds anticipation]

フックのチェックリスト

フックを完成させる前に、以下を確認してください。

• 具体的：ありきたりな表現ではない（「この動画で人生が変わります」❌）
• 価値を約束している：視聴するメリットが明確
• 好奇心をかき立てる：答えのない問いや、結果の予告がある
• 内容に合っている：無関係なフックで釣らない
• プラットフォームに適している：長さとスタイルがプラットフォームに合っている
• 口に出しやすい：自然に話しやすい
• テロップに使える：画面上のテキストと組み合わせても成立する

よくあるフックの失敗

失敗	例	改善策
ありきたりすぎる	「皆さん、こんにちは。おかえりなさい」	価値やフックから始める
長すぎる	フックの前に15秒のイントロ	最初の3秒でフックを入れる
好奇心を引かない	「今日はXをご紹介します」	結果や意外な点を予告する
釣りタイトル	内容と無関係なフック	フックに見合う内容を届ける
冒頭の言葉が弱い	「ええと、今日は……」	印象的な最初の言葉を使う
視覚的なフックがない	話し手の顔だけで始める	テキストや視覚要素を加える
