Channel Rules

This skill defines the constraints and best practices for each marketing channel.

LinkedIn

Constraints

  • •Maximum length: 3,000 characters
  • •Tone: Professional, thought-leadership
  • •Required elements: Hook, value proposition, CTA

Structure

  1. •Hook (first line): Attention-grabbing opener
  2. •Value proposition: What the reader will gain
  3. •Details: Key information (2-3 bullet points work well)
  4. •CTA: Clear call-to-action with link
  5. •Hashtags: 3-5 relevant hashtags

Best Practices

  • •First line is crucial (appears before "see more")
  • •Use line breaks for readability
  • •Include 3-5 relevant hashtags at the end
  • •Tag relevant people/companies when appropriate

Example Format

code
[Attention-grabbing hook - 1 line]

[Value proposition - what they'll learn/gain]

Key takeaways:
• Point 1
• Point 2
• Point 3

[CTA with link]

#Hashtag1 #Hashtag2 #Hashtag3

Email

Constraints

  • •Subject line: Maximum 60 characters
  • •Body: Maximum 300 words
  • •Tone: Direct, personalized, like writing to a colleague

Structure

  1. •Subject: Clear, compelling, action-oriented
  2. •Greeting: Personal (Hi [Name] or Hello)
  3. •Opening: Get to the point quickly (1-2 sentences)
  4. •Value: What's in it for them
  5. •Details: Key information
  6. •CTA: Single, clear call-to-action
  7. •Signature: Brief closer

Best Practices

  • •Subject line should create curiosity or promise value
  • •Get to the point in the first sentence
  • •ONE primary CTA (don't overwhelm with choices)
  • •Keep paragraphs short (2-3 sentences max)
  • •Mobile-friendly formatting

Example Format

code
Subject: [Action verb] [Benefit] - [Event/Date]

Hi [Name],

[Opening hook - why should they care?]

[Value proposition - what they'll gain]

[Key details - date, time, what to expect]

[CTA button/link]

Best,
[Signature]

Web (Landing Page Hero)

Constraints

  • •Headline: Maximum 10 words
  • •Subhead/Hero paragraph: Maximum 50 words
  • •Tone: Punchy, scannable, benefit-driven

Structure

  1. •Headline: Clear, benefit-focused, action-oriented
  2. •Subhead: Expands on headline with specific details
  3. •CTA button: Single action

Best Practices

  • •Headline answers: "What's in it for me?"
  • •Use power words that drive action
  • •Keep it scannable - users skim
  • •CTA button text should be specific ("Register Now" not "Submit")
  • •SEO-friendly: include relevant keywords

Example Format

code
Headline: [Verb] [Benefit] in [Timeframe/Context]

Subhead: [Expand on the promise with specific details, outcomes, or social proof. Keep it to 1-2 sentences.]

[CTA Button Text]

Facebook

Constraints

  • •Maximum length: 500 characters
  • •Tone: Conversational, engaging
  • •Required elements: Hook, benefit, CTA

Structure

  1. •Hook: Grab attention immediately
  2. •Benefit: What they'll gain
  3. •CTA: Clear action with link

Best Practices

  • •More casual tone than LinkedIn
  • •Use emojis sparingly if appropriate for brand
  • •Keep it short and punchy
  • •Link should be in a separate line or clear

Example Format

code
[Hook - question or bold statement]

[Benefit - what's in it for them]

[CTA with link]

Length Validation

When critique_draft checks length:

  • •It counts all characters (headline + body + cta)
  • •If length_ok is false, you MUST reduce content
  • •Priority for cutting: Details > Supporting points > Core message

Common Issues

  1. •Too long: Cut redundant phrases, combine points
  2. •Missing CTA: Every piece needs a clear next step
  3. •Vague CTA: "Learn more" → "Register for the webinar"
  4. •Missing hook: LinkedIn/Email need strong openers
  5. •Wrong tone: LinkedIn ≠ Email ≠ Web
