Keyword Cluster Mapper: Plan a Coaching Blog That Ranks

Most coaches start a blog the same way: they brainstorm a few topics, write whatever feels interesting that week, and wonder six months later why nothing ranks. The problem is rarely the writing. It’s that the posts don’t reinforce each other, so Google never sees you as an authority on any one subject.

This skill fixes the planning step. Done well, keyword research for coaches isn’t about chasing a hundred random terms; it’s about grouping them into a few tight clusters where one broad “pillar” post is supported by several narrow ones that link back to it. Paste in your niche and a messy list of ideas, and this reusable AI skill returns a prioritized pillar-and-cluster map you can write from for months. By the end of this page you’ll also understand why the structure works, so you can keep extending the plan yourself.

When to use this

• You’re starting a coaching blog and don’t know which posts to write first.
• You have a pile of keyword ideas from Google autocomplete, client questions, or a tool, and no way to organize them.
• You’ve been publishing for a while but nothing ranks because the posts are unconnected.
• You want a publishing order that matches how often you can realistically write.
• You’re briefing a writer or VA and need a clear content map to hand over.

The skill

Paste this whole block into a ChatGPT Custom GPT’s Instructions field or a Claude Project’s custom instructions:

ROLE
You are an SEO content strategist who specializes in coaching businesses. You understand topic clusters: a single "pillar" page targets a broad, high-intent term, and several "supporting" posts target narrower long-tail terms and link back to the pillar. Your job is to turn a coach's messy keyword list into a clean, prioritized content map they can write from.

INPUTS
The coach will give you:
- NICHE: their coaching niche
- IDEAL_READER: who they serve and what that person struggles with
- KEYWORD_LIST: a raw, unsorted list of keywords or topic ideas
- BUSINESS_GOAL: the action a reader should eventually take
- CONTENT_CADENCE: how often they can publish

PROCESS
1. First, if NICHE, IDEAL_READER, or KEYWORD_LIST is missing or vague, ask up to 3 clarifying questions and stop. Do not guess. If everything is clear, proceed.
2. Read the KEYWORD_LIST and infer the search intent behind each item (informational, commercial, or transactional).
3. Group the keywords into 3-5 topic clusters. Each cluster is a theme your IDEAL_READER cares about.
4. For each cluster, name ONE pillar topic (broad, the hub) and 3-6 supporting topics (narrow, the spokes). You may add a few obvious missing keywords the coach forgot, but flag them as [suggested].
5. Prioritize clusters by how directly they move a reader toward BUSINESS_GOAL and how realistic they are to rank for as a small coaching site (favor lower-competition long-tail).
6. Map the plan onto the CONTENT_CADENCE so the coach knows what to write first.

OUTPUT FORMAT
Return, in this order:
1. A one-line summary of the strategy.
2. A section per cluster, in priority order, formatted as:
   ### Cluster N: [Cluster name]  (Priority: High/Medium/Low)
   - Pillar: [pillar title] — target keyword, intent
   - Supporting posts: a bulleted list, each as [working title] — target keyword, intent
   - Internal linking note: one sentence on how the spokes link to the pillar.
3. A "Publishing order" table mapping the next 6 posts to the cadence (Slot, Post title, Cluster, Why now).
4. A "What I'd skip" note listing any keywords from the list that aren't worth targeting yet, with a one-line reason.

RULES
- Titles must be specific and reader-facing, not keyword soup. Write titles a human would click.
- Never invent fake search volumes or traffic numbers. Reason about intent and competition qualitatively.
- Keep every supporting post genuinely distinct; no two posts that would cannibalize each other.
- Tie at least one cluster directly to BUSINESS_GOAL.
- No buzzwords. Be concrete and practical.

How to set it up

1. Open the right place. In ChatGPT, go to your name > ‘My GPTs’ > ‘Create a GPT’, then the ‘Configure’ tab. In Claude.ai, create a Project and open ‘Set custom instructions’.
2. Paste the skill. Drop the entire block above into the Instructions field.
3. Name and save it as something like ‘Coaching Blog Keyword Mapper’.
4. Use it by starting a chat and pasting your five inputs below. The skill asks clarifying questions first if anything is thin.

The five inputs it expects:

See it in action (full example)

Here is the exact set of inputs a career coach pasted into the saved skill. This is the whole input, nothing hidden:

NICHE: career coaching for mid-career women in tech
IDEAL_READER: women engineers and PMs, 5-12 years in, who feel stuck right before the jump to manager. They're competent but keep getting passed over and don't know how to position themselves.
KEYWORD_LIST: how to ask for a promotion, imposter syndrome at work, salary negotiation script, mid-career pivot, how to find a mentor, career roadmap template, getting passed over for promotion, how to become an engineering manager, performance review tips, women in tech leadership
BUSINESS_GOAL: book a free career strategy call
CONTENT_CADENCE: two posts per month

And here is the complete output the model returns:

Strategy in one line: Build authority around “getting promoted in tech” first, because that cluster maps most directly to a reader who’s ready to book a strategy call, then expand into mindset and positioning.

Cluster 1: Getting promoted in tech (Priority: High)

• Pillar: How to Get Promoted to Engineering Manager (A Step-by-Step Playbook) — target keyword how to become an engineering manager, informational/commercial
• Supporting posts:
• How to Ask for a Promotion Without Sounding Pushy (Word-for-Word Scripts) — how to ask for a promotion, informational
• Passed Over for Promotion? Here’s What It Usually Means and What to Do Next — getting passed over for promotion, informational
• The Mid-Career Tech Roadmap: Mapping Your Next 18 Months — career roadmap template, informational
• How to Use Your Performance Review to Set Up a Promotion — performance review tips, informational
• Internal linking note: Every supporting post links up to the pillar with anchor text like “the full promotion playbook,” and the pillar links down to each spoke in its relevant section.

Cluster 2: Owning your value (mindset + positioning) (Priority: High)

• Pillar: The Confidence Gap in Tech: How Competent Women Get Overlooked (and How to Stop It) — target keyword imposter syndrome at work, informational
• Supporting posts:
• 7 Signs Imposter Syndrome Is Quietly Capping Your Career — imposter syndrome signs [suggested], informational
• How to Talk About Your Wins So Leadership Actually Notices — self-promotion at work [suggested], informational
• Salary Negotiation Scripts for Women in Tech (With Exact Lines) — salary negotiation script, commercial
• Internal linking note: The salary and self-promotion spokes link to the pillar as “the root cause of the confidence gap,” and the pillar funnels readers toward the strategy call.

Cluster 3: Support and direction (Priority: Medium)

• Pillar: How to Find a Mentor (or Sponsor) When You’re a Mid-Career Woman in Tech — target keyword how to find a mentor, informational
• Supporting posts:
• Mentor vs. Sponsor: Which One Actually Gets You Promoted — mentor vs sponsor [suggested], informational
• Thinking About a Mid-Career Pivot? Read This First — mid-career pivot, informational
• Breaking Into Women-in-Tech Leadership: What the Path Really Looks Like — women in tech leadership, informational
• Internal linking note: Each spoke links to the mentor pillar and cross-links to Cluster 1, since mentorship and promotion go together.

Publishing order (two posts/month):

Slot	Post title	Cluster	Why now
Month 1, post 1	How to Get Promoted to Engineering Manager (Pillar)	1	Anchor the highest-intent cluster first so spokes have a hub to link to
Month 1, post 2	How to Ask for a Promotion Without Sounding Pushy	1	Lowest-competition, high-intent quick win
Month 2, post 1	Passed Over for Promotion? What It Means and What to Do	1	Strong emotional search; pairs naturally with the pillar
Month 2, post 2	The Confidence Gap in Tech (Pillar)	2	Launch the mindset hub; broad reach, feeds the call
Month 3, post 1	Salary Negotiation Scripts for Women in Tech	2	Commercial intent, closest to booking a call
Month 3, post 2	The Mid-Career Tech Roadmap	1	Completes Cluster 1 and works as a lead magnet

What I’d skip (for now): – mid-career pivot as a standalone priority — kept as a Cluster 3 spoke, but it pulls readers who may be leaving tech, which is off your core promotion goal. Revisit if you add a pivot offer.

Want me to draft the outline for the Cluster 1 pillar next?

That is a full quarter of blog posts, in order, each one strengthening the next. No more staring at a blank editor wondering what to write.

Why this works

Four principles are doing the heavy lifting. Learn them and your prompting gets sharper everywhere, not just here.

1. Role priming sets the lens. Opening with “You are an SEO content strategist who specializes in coaching businesses” tells the model which slice of its knowledge to use. “Give me blog topics” pulls from the bland average of the internet; naming an expert role pulls from how strategists actually think about intent and competition.
2. Specificity in, specificity out. The skill forces you to supply a real reader, a real list, and a real business goal. A vague reader (“professionals”) produces vague titles. A sharp one (“women engineers stuck before the manager jump”) produces titles people actually click. The output can only be as specific as your inputs.
3. Constraints are quality control. Rules like “never invent fake search volumes,” “keep every supporting post distinct so they don’t cannibalize,” and “tie at least one cluster to the business goal” each remove a common failure mode. Telling the model what NOT to do is as powerful as telling it what to do.
4. Clarifying questions beat guessing. The very first process step tells the model to ask up to 3 questions and stop if your inputs are thin. This single instruction is the biggest fix for generic AI output, because it lets the model fill gaps with your real context instead of plausible-sounding filler.

The deeper idea is the cluster structure itself: search engines reward sites that cover one topic thoroughly and link the pieces together. A pillar plus its spokes signals depth on a subject far better than ten unrelated posts, which is why this beats brainstorming topics one at a time.

Do this now

1. Set up the skill as a Custom GPT or Claude Project using the block above.
2. Spend ten minutes dumping every keyword and client question you can think of into one list. Messy is fine.
3. Paste your five inputs and run it. Answer any clarifying questions honestly.
4. Take the first row of the Publishing order table and outline that post this week.

Pro tips

• Feed it real client questions. The exact phrases prospects email you are gold; they’re how your buyers actually search. Add them to the KEYWORD_LIST.
• Ask for the pillar outline next. Once you like the map, reply “draft the outline for the Cluster 1 pillar” and keep the momentum in the same chat.
• Re-cluster every quarter. Drop in new keyword ideas and ask it to re-prioritize against what you’ve already published, so you don’t repeat yourself.
• Pressure-test the priorities. Ask “which one cluster, if I only wrote it, would most likely lead to a booked call?” to sanity-check where you start.
