What you'll accomplish
By the end of this guide, you'll have a 90-day editorial calendar — complete with weekly topics, target keywords, content types, and distribution channels — that you can hand to a client or use to plan your own content output. What usually takes 3–4 hours of planning becomes a 30-minute collaborative session with Claude.
What you'll need
The quality of the calendar depends entirely on the quality of what you give Claude. Before starting, collect:
Start a new Claude conversation with this setup:
I need you to create a 90-day editorial content calendar. Here are the details:
CLIENT/BRAND: [Name and one-sentence description]
AUDIENCE: [Target reader description]
CONTENT GOALS: [List 3-5 goals]
TOPIC PILLARS: [List 5-10 main subject areas]
CONTENT TYPES: [e.g., "blog posts (1/week), LinkedIn posts (3/week), email newsletter (1/week)"]
PUBLISH FREQUENCY: [X pieces per week total]
KEYWORDS TO TARGET: [List any specific keywords, or say "suggest relevant keywords"]
UPCOMING EVENTS/PROMOTIONS: [Any product launches, seasons, or campaigns to build around]
Create a week-by-week 90-day calendar. For each week, provide:
- Week theme (connecting that week's content)
- Blog post title + target keyword
- 2-3 LinkedIn post topics
- Email newsletter angle (if applicable)
- Notes on any connections between pieces
What you should see: Claude generates a structured week-by-week calendar spanning 13 weeks (90 days ÷ 7).
Read through the calendar critically:
Tell Claude what to adjust: "Week 7 feels too similar to Week 3 — change the theme and topics. Also, make the April content heavier on [topic] because that's when our target audience is planning Q3 budgets."
Ask Claude to format the calendar for a spreadsheet:
"Now format the entire 90-day calendar as a table I can paste into Google Sheets. Columns: Week Number | Publish Date | Content Type | Title/Topic | Target Keyword | Distribution Channels | Status (leave blank)."
What you should see: A markdown table with all 13 weeks formatted cleanly.
Copy the table → paste into Google Sheets (use "Paste special → Paste as values" → the table formatting comes through). Add a "Status" column and you have a working editorial calendar.
A 90-day view is for planning. The first 4 weeks need to be execution-ready. Ask Claude:
"For weeks 1–4, expand each piece with: a 3-bullet outline for the blog post, a draft headline for the LinkedIn posts, and a subject line for the email newsletter. Include a suggested intro angle for each blog post."
What you should see: Detailed execution-ready plans for the first month — enough to brief a writer or start writing yourself without additional planning.
Full calendar generation: "Create a [X]-week editorial calendar for [brand] targeting [audience]. Pillars: [list]. Types: [list]. Goals: [list]. Format: Week | Date | Type | Title | Keyword | Channels."
Refining a specific week: "Week [X] feels too similar to Week [Y]. Replace the theme and generate 3 new content angles that connect to [pillar] without repeating what we've already covered."
Expanding detail for execution: "For Week [X], expand the blog post with a 5-point outline and a suggested intro approach. Expand each LinkedIn post with a draft first sentence."
Checking calendar balance: "Look at the full 13-week calendar. Flag any: topic repetitions, weeks with no clear theme connection, or gaps in keyword coverage based on our target pillars."
