The Prompt

Act as a content strategist who manages editorial calendars for 7-figure online businesses.
Build a 30-day content calendar for:
Business type: {type — e.g. SaaS, e-commerce, coaching, agency}
Platforms: {e.g. Instagram, LinkedIn, newsletter, blog, YouTube}
Content pillars (3-5 themes): {e.g. education, behind-the-scenes, social proof, promotion, entertainment}
Posting frequency per platform: {e.g. Instagram 5x/week, newsletter 1x/week}
Product/service being promoted: {what you sell}
Monthly theme or goal: {e.g. new product launch, Q3 revenue push, audience growth}

Output:
1. Content pillar breakdown (what % of content per pillar and why)
2. Week 1-4 calendar in table format:
   | Date | Platform | Pillar | Content type | Topic/angle | Format notes |
3. 5 full content ideas (title + 3-sentence description + ideal format) for the highest-priority platform
4. Cross-posting opportunities (which pieces can be repurposed across platforms)
5. One campaign arc suggestion (3-5 posts that build on each other to a CTA)

Constraints:
- No more than 20% promotional content across the month
- At least one "save-worthy" post per week on each social platform
- Campaign arc must have a natural progression (education → social proof → CTA)
- Flag any ideas that require advance production (video, graphics) with a [LEAD TIME] note

  • {platforms} Where you publish content
  • {content pillars} 3-5 recurring themes for your content

The 80/20 content rule prevents audience burnout

Audiences tolerate promotional content when it’s surrounded by genuine value. The prompt enforces no more than 20% promotional content — which mirrors the rule used by the most-followed brand accounts. An audience that trusts your content clicks your promotions. An audience that sees too many promos unfollows.

Content pillars are the framework, not a constraint

Pillars give your content a consistent identity without forcing every post into a template. When a pillar is broad enough (‘education about your space’), it can accommodate timely news, evergreen how-tos, and opinion pieces — all under the same strategic umbrella.

Batch creation beats daily posting

The prompt’s output is designed to be used in one monthly planning session, not daily. Research consistently shows that batching content creation — producing 20 posts in one 3-hour session — produces higher quality than scrambling for ideas every morning before posting.
