- Modes: Pillar expansion, calendar batching, local modifiers, channel adaptation — Prompt-driven workflows for repeatable quality

## What this generator solves

Stop starting content planning from empty spreadsheets or undifferentiated keyword lists. This generator converts a pillar topic or seed keyword into prioritized subtopics labeled by search intent, paired with suggested headings, short meta descriptions and concrete angles that a writer can execute.

- Move from idea to publish-ready brief: H2/H3 headings + 20–30 word meta descriptions
- Align subtopics to intent (informational, transactional, navigational) for better editorial prioritization
- Produce local and channel-adapted variations in the same workflow

## How it works — practical workflow

Select a pillar topic or seed keyword, choose a prompt template (expansion, SERP mining, local modifiers, calendar batching) and run a batch. Review generated subtopics, adjust editorial priority, then export to CSV or a Docs outline for handoff. Reuse prompt templates to maintain consistency across authors and markets.

- Pillar input -> grouped subtopics with intent labels
- Quick review controls to mark priority and set publish cadence
- Export-ready briefs for CMS or collaboration tools

## Prompt templates you can use immediately

Below are concrete prompt clusters used to produce high-signal subtopics. Copy these into the generator and replace placeholders with your pillar, keyword or locale.

### Pillar-to-subtopic expansion

Generate grouped subtopics with headings, meta descriptions and keywords.

- Prompt: "Given pillar topic: {pillar}, generate 15 subtopics grouped by search intent (informational, transactional, navigational). For each subtopic provide a suggested H2, a short meta description (20–30 words), 2 target keyword phrases, and a recommended content angle."

### Question and SERP-insight mining

Extract common user questions and headings from top results to shape FAQ and heading structure.

- Prompt: "Analyze top-10 SERP results for keyword: {keyword} and extract the 10 most common user questions and subtopic headings. Prioritize by relevance and include a one-line intent summary for each."

### Long-tail & local modifiers

Create localised subtopics for city-level or region-specific pages.

- Prompt: "For seed keyword: {keyword} and locale: {city},{country}, generate 12 local long-tail subtopics that include local modifiers, intent label, and a suggested local CTA or resource."

### Content calendar batching

Turn one pillar into a weekly schedule with internal linking suggestions.

- Prompt: "Create a 12-week content calendar from pillar: {pillar}. Output weekly subtopic, editorial priority (high/medium/low), suggested publish date cadence, and 2 internal linking suggestions per post."

### Channel adaptation

Derive blog, video and social topics from a single idea.

- Prompt: "Take pillar: {pillar} and produce: 8 blog post subtopics, 5 short-video topics, and 6 social post hooks. For each item include recommended length, angle, and one repurposing tip."

### Competitive gap discovery

Identify topical gaps you’re missing versus a competitor.

- Prompt: "Given target site: {your_domain} and competitor: {competitor_domain}, list topical subtopics the competitor covers that the target does not. For each gap, suggest a content angle and priority for coverage."

### FAQ and schema-ready topics

Produce short FAQ entries optimized for snippet and schema usage.

- Prompt: "Generate 10 FAQ entries and short answers for subtopic: {subtopic} optimized for featured snippets and FAQ schema."

## Batching, calendars and editorial handoff

Use batch mode to populate a content calendar with ranked priorities, publish cadence and internal-link suggestions. Export as CSV for spreadsheets or as a Docs/Notion-friendly outline for writers. Include a short brief field for each subtopic so editors get context: goal, target audience, and suggested length.

- 12-week calendar templates with editorial priority and linking cues
- Export briefs in formats editors already use (CSV, Google Docs, Notion outline)
- Prompt templates to enforce consistent brief quality across authors

## Local SEO and channel adaptation

Generate local long-tail phrases and CTAs for city pages plus separate channel-adapted subtopics for blog, video and social. This creates a single source-of-truth for cross-team repurposing and reduces duplicated planning work.

- Local modifiers that reflect region-specific intent and resources
- Short-video and social hooks derived from each subtopic to increase repurposing velocity
- Guidance for mapping a subtopic to the best publishing channel

## Workflow

1. 1. Input pillar or seed keyword
Start with a clear pillar topic or high-value seed keyword and select the right prompt template (expansion, SERP mining, local modifiers).

2. 2. Choose mode and locale
Pick single-run expansion or batch calendar mode; set locale for geo-targeted output when needed.

3. 3. Review generated subtopics
Scan H2/H3 headings, short meta descriptions and intent labels. Mark editorial priority and remove duplicates.

4. 4. Export and hand off
Export the prioritized list to CSV or a Docs/Notion outline. Attach the brief and assign to writers with internal-link suggestions.

5. 5. Monitor & iterate
After publishing, use SERP checks and site analytics to refine prompt templates and update the calendar based on performance and seasonality.

## FAQ

### What is the difference between a subtopic, keyword, and content pillar?

A pillar is a broad central topic that groups related content. Subtopics are narrower angles or sections that sit under that pillar (usually H2/H3 headings). Keywords are search terms users type; one subtopic can target multiple keywords. Use pillars to organize site architecture, subtopics for page structure and keywords to refine on-page optimization.

### How do I map subtopics to search intent and editorial priority?

Label each generated subtopic by intent: informational (how-to, guides), transactional (product or service pages), or navigational (brand/resource pages). Set editorial priority by business impact and search opportunity: high priority for high-intent or gap coverage, medium for evergreen informational pieces, low for experimental long-tail topics.

### What prompts produce the most unique angles versus generic lists? (examples included)

Prompts that combine SERP analysis with audience context yield the best unique angles. Example: ask for 'top-10 SERP question extraction' and add 'audience: busy parents' or 'audience: local small businesses' to push the generator toward differentiated, audience-led angles instead of generic lists.

### How can I use generated subtopics in a multi-author editorial workflow? (export and handoff best practices)

Export each subtopic as a short brief (H2 title, 20–30 word meta, 2 keywords, recommended angle, and suggested length). Attach editorial priority and two internal links. Use Google Docs or Notion outlines for versioning and add a short reviewer checklist (verify intent, add sources, localize CTAs) before assigning to writers.

### How do I adapt subtopics for local SEO and region-specific search behavior?

Run the local modifiers prompt with a city and country placeholder so each subtopic includes local terms, regional resources and a local CTA. Validate with Google Business Profile insights and local SERP checks, then customize examples and phone/address CTAs in the brief.

### What quality checks should editors apply after automated subtopic generation?

Editors should verify: intent alignment, uniqueness against existing pages, factual plausibility of suggested angles, and keyword realism. Run a quick SERP check to ensure the proposed heading matches user expectations and update the brief with primary sources or competitor gaps as needed.

### Which output formats are best for integrating into CMS or content briefs?

CSV is ideal for spreadsheet-based scheduling; Google Docs and Notion outlines work best for collaborative briefs and writing. Include a one-line brief per subtopic to speed assignment and copy the suggested H2/H3 structure directly into the CMS template to ensure consistent on-page formatting.
