Claude for Content Strategists: Build a 90-Day Content Calendar from Scratch

You are an expert content strategist with 11 years of experience building content programs from zero for B2B SaaS and D2C brands where a structured 90-day content calendar is the primary mechanism for moving from sporadic publishing to consistent, audience-building content that supports pipeline growth, reduces churn through education, and compounds organic traffic over time. Help me build a 90-day content calendar so I can launch a consistent publishing program that covers all key buyer journey stages, targets high-intent keywords we can realistically rank for at our current domain authority, and gives the content team a clear weekly production schedule they can execute without a dedicated content director. My situation: - Brand and audience context: [e.g., "a Series A B2B SaaS company building project management software for architecture firms — our ICP is senior project managers and operations directors at architecture firms with 10–100 employees — they struggle with project budget overruns, coordination across contractors, and client deliverable tracking"] - Current content state: [e.g., "we have published 14 blog posts in the past 18 months — no consistent cadence — the posts were written by the founding team and cover general productivity topics rather than architecture-specific pain points — domain authority is 18 — no pillar pages or topic clusters exist"] - Publishing capacity: [e.g., "one part-time content writer (20 hours per week), one designer for graphics (4 hours per week), and founder availability for one 45-minute expert interview per month — budget for 2 freelance posts per month at $300 each"] - SEO and keyword targets: [e.g., "want to target keywords with monthly search volume between 200–2,000 and keyword difficulty below 35 — primary topic areas: construction project management software, architecture project tracking, AEC project management, construction budget templates"] - Business goals: [e.g., "primary goal is organic lead generation — secondary goal is supporting sales with bottom-of-funnel comparison and use-case content — no podcast or video production in scope for this quarter"] - Content formats in scope: [e.g., "long-form blog posts (1,500–3,000 words), downloadable templates (Excel or Google Sheets), and short LinkedIn posts repurposed from blog content — no video, no email newsletter for this quarter"] Deliver: 1. A topic cluster architecture — three pillar topics each with 8–10 supporting cluster posts, mapped to the three buyer journey stages (awareness, consideration, decision) — each cluster post title must include a realistic target keyword, an estimated monthly search volume, and an estimated keyword difficulty score for a DA-18 site 2. A 90-day weekly publishing calendar — a table with columns for week number, publish date, content title, content format, target keyword, word count target, assigned writer (in-house or freelance), and the buyer journey stage — the calendar must produce 2 pieces of long-form content per week (8 per month) and include 4 template downloads distributed across the 90 days 3. A content brief template — a reusable brief structure for the in-house writer covering: target keyword and secondary keywords, search intent classification, recommended H2 and H3 structure, internal linking requirements (minimum 3 links to existing content), word count range, CTA placement, and the one question the post must definitively answer 4. A founder interview framework — a 45-minute interview guide with 12 questions the content writer asks the founder each month to extract architecture-industry-specific insights, quotes, and case study details that differentiate the blog content from generic project management content written by AI 5. A LinkedIn repurposing system — for each long-form blog post, a 3-post LinkedIn sequence: a hook post on publish day (problem framing), a data or insight post on day 4 (key stat or framework from the article), and a CTA post on day 7 (linking to a template download or demo booking) — with character counts and formatting guidance for each post type 6. A 90-day performance tracking dashboard — a Google Sheets template structure with columns for: post title, publish date, target keyword, Google Search Console clicks (weekly), Google Search Console impressions (weekly), average position, and a 90-day traffic projection based on a conservative 3-month ranking timeline for DA-18 sites targeting KD < 35 keywords 7. A month-3 content audit trigger — a decision framework for evaluating which of the first 8 posts to update versus retire at the 90-day mark, based on impressions above 500 but clicks below 1% CTR (title/meta optimization candidate), impressions below 100 (topic or keyword pivot needed), and clicks above 20 per week (expand with a follow-up post or template) **Format the 90-day calendar as a markdown table with all 12 weeks populated — every row must include a specific post title, not a placeholder — the calendar must be immediately usable by the content writer on day one without requiring additional research or planning.**
