Blog Calendar -- Editorial Planning

Generates editorial calendars with topic clusters, publishing cadence, freshness update schedules, content decay detection, template recommendations, distribution planning, and seasonal hooks. Optimized for building topical authority (Google) and maintaining citation freshness (AI platforms).

Workflow

Step 1: Understand the Blog

Gather context:

1. Niche/industry -- What is the blog about?
2. Existing content -- Scan for existing blog posts (Glob for *.md, *.mdx, *.html)
3. Publishing cadence -- How often can they publish? (default: 2x/week)
4. Timeframe -- Monthly or quarterly calendar?
5. Business goals -- What should the blog drive? (traffic, leads, authority)

Step 2: Topic Cluster Design

Design 3-5 topic clusters (pillar + supporting content):

Cluster: [Pillar Topic]
├── Pillar Page: [Comprehensive guide - 3,000+ words]
├── Supporting: [Subtopic 1 - 2,000 words]
├── Supporting: [Subtopic 2 - 2,000 words]
├── Supporting: [Subtopic 3 - 1,500 words]
├── Comparison: [X vs Y - 1,500 words]
└── FAQ: [Common questions - 1,500 words]

Step 2.5: Content Decay Detection

Scan existing blog posts for lastUpdated or date fields in frontmatter. Classify each post by staleness:

Traffic Level	Stale Threshold	At-Risk Threshold
High-traffic posts	>30 days since update	>90 days
Medium-traffic posts	>90 days since update	>180 days
Low-traffic posts	>180 days since update	>365 days

Reference: 76% of top AI citations are from content updated within 30 days.

Step 3: Freshness Update Schedule

Plan update cycles:

• High-priority posts (traffic drivers): Update every 30 days
• Medium-priority posts: Update every 90 days
• Low-priority posts: Update annually

Step 4: Seasonal & Trending Hooks

Research seasonal opportunities:

1. Industry events -- Conferences, product launches, algorithm updates
2. Seasonal trends -- Use WebSearch to check Google Trends for the niche
3. Annual reports -- When do major studies release new data?

Step 5: Generate the Calendar

Content Mix Formula

Apply: 60% new content / 30% freshness updates / 10% repurposed content

Cadence	Monthly Posts	New	Refreshes	Repurposed
2 posts/week	8	5	2	1
3 posts/week	12	7	4	1
1 post/week	4	2-3	1	0-1

Monthly Calendar Format

# Editorial Calendar: [Month Year]

## Publishing Cadence: [N] posts/week
## Content Mix: [N] new / [N] refreshes / [N] repurposed

### Week 1: [Date Range]
| Day | Type | Title | Template | Cluster | Target Keyword | Status |
|-----|------|-------|----------|---------|---------------|--------|
| Mon | New | [Title] | how-to-guide | [Cluster] | [keyword] | Draft |
| Thu | Update | [Existing post] | -- | [Cluster] | [keyword] | Refresh |

[... repeat for weeks 2-4 ...]

## Freshness Update Queue
| Post | Last Updated | Priority | Scheduled |
|------|-------------|----------|-----------|

## Seasonal Hooks
- [Event/trend and how to leverage it]

Step 5.5: Topic Cluster Progress Tracking

## Topic Cluster Progress
| Cluster | Pillar | Spokes Published | Spokes Planned | Coverage |
|---------|--------|-----------------|----------------|----------|
| [Topic] | Published | 5/10 | 5 this quarter | 50% |

Rules:

• Clusters at 50%+ coverage: highest priority to complete
• Never have more than 3 clusters in active build-out simultaneously

Step 5.6: Distribution Scheduling

Post	Publish Date	LinkedIn	Reddit	Email	YouTube
[Title]	[Date]	Same day	+2-3 days	Next batch	If pillar

Step 6: Save & Next Steps

Save the calendar and suggest:

1. Start with /smart-blog-skills:brief <first-topic> to create the first content brief
2. Use /smart-blog-skills:write to generate articles from briefs
3. Use /smart-blog-skills:rewrite for freshness updates on existing content
4. Re-run /smart-blog-skills:calendar next month/quarter for the next plan
