Custom GPT: Your Dedicated SEO Content Brief Generator
For SEO Specialist / Content Marketing Managers ·
What This Builds
A Custom GPT configured with your agency's content brief template, SEO standards, and formatting rules — so you can generate a complete brief by typing a single line instead of re-explaining your format every time. Instead of a 90-minute brief process, you get a structured draft in under 10 minutes.
Prerequisites
- {{tool:ChatGPT.plan}} subscription ({{tool:ChatGPT.price}}) — Custom GPT builder requires a paid plan
- Your current content brief template (written out in text form)
- Any agency SEO standards you want consistently applied
- 1-2 hours to build and test the GPT
The Concept
A Custom GPT is like a pre-configured colleague who already knows your brief format, your quality standards, and how you like things structured. Every conversation starts from that shared understanding — you don't need to explain "use our 10-point format" every time. You just say "brief for: project management software for nonprofits" and it outputs the full thing.
Build It Step by Step
Part 1: Prepare your GPT's knowledge base
Before building the GPT, collect these documents in text form:
Your content brief template — Write out your current 10-15 point brief structure in plain text:
Copy and paste thisCONTENT BRIEF TEMPLATE 1. Title tag (under 60 chars, keyword first) 2. Meta description (under 160 chars, benefit-focused) 3. Target word count 4. H1 (different from title tag) 5. H2/H3 outline with section descriptions 6. Featured snippet opportunity (yes/no + target section) 7. Semantic terms to include (from keyword research) 8. Competitor gaps (2-3 topics competitors cover that we should) 9. Internal linking targets (2-3 existing pages) 10. Target keyword + related termsYour SEO writing standards — e.g., "Use Oxford comma. Never use passive voice in headers. Lead with the benefit. Target 8th grade reading level for consumer content, 11th grade for B2B."
Your typical client industries — A 1-paragraph description of each industry you serve, so the GPT can add industry-appropriate examples
Save all of this as a single text file.
Part 2: Build the Custom GPT
- Go to {{tool:ChatGPT.url}} and log in
- Click your profile icon → My GPTs
- Click Create (or Create a GPT)
- You'll see two panels: the Create panel (where you configure) and the Preview panel (where you test)
In the Create panel:
Name your GPT: SEO Content Brief Generator
Description: Generates complete SEO content briefs using [AGENCY NAME]'s standard template and SEO methodology
Instructions (this is the system prompt — paste this, customized):
You are an expert SEO content strategist at [AGENCY NAME]. Your job is to generate complete, actionable content briefs that our writers can execute without asking clarifying questions.
BRIEF FORMAT (always follow this exactly):
1. TITLE TAG — under 60 characters, include primary keyword near the start
2. META DESCRIPTION — under 160 characters, benefit-focused, includes keyword, ends with a subtle CTA
3. TARGET WORD COUNT — specific range (e.g., 1,800-2,200 words) based on the data I provide; if no data given, ask for it
4. H1 — slightly different from title tag, uses keyword naturally, speaks to reader's goal
5. CONTENT OUTLINE — full H2/H3 structure. For each H2, include a 1-sentence description of what the section should cover
6. FEATURED SNIPPET OPPORTUNITY — identify one section most likely to capture a featured snippet; specify the format (definition paragraph / numbered list / comparison table)
7. SEMANTIC TERMS TO INCLUDE — at least 10 related phrases that should appear naturally throughout. List them as: [term] — [1-2 word context for where to use it]
8. COMPETITOR GAPS — 3 specific subtopics or angles that competitor articles are missing (requires me to provide competitor data)
9. INTERNAL LINKING TARGETS — ask me for a list of existing pages, then suggest 2-3 specific links with recommended anchor text
10. QUICK REFERENCE — one-line summary of: content type, tone, primary audience, keyword difficulty if known
SEO STANDARDS TO APPLY:
[Paste your agency's writing standards here]
BEHAVIOR:
- When given just a keyword, output the complete brief structure and ask for the data needed (competitor URLs, SERP info) if not provided
- When given full SERP data + keyword, generate the complete brief in one pass
- If content gap data (e.g., keywords competitors rank for but I don't) is included, incorporate it into the Semantic Terms and Competitor Gaps sections
- Always flag if a brief topic has obvious E-E-A-T requirements (medical, legal, financial, YMYL content) with a note: "⚠️ YMYL content — needs author credentials and authoritative sources"
NEVER DO:
- Generate titles over 60 characters without flagging them
- Recommend exact keyword density targets (this is outdated SEO advice)
- Suggest AI-generated content be published as-is without human expert review
Part 3: Upload your knowledge files
- In the GPT builder, look for Knowledge section
- Click Upload files
- Upload your brief template text file and any industry reference documents
- These are now permanently accessible to the GPT — it can reference your exact format
Part 4: Configure conversation starters
Add 3 quick-start prompts that appear as buttons when someone opens the GPT:
Generate brief for: [keyword]I have SERP data — here's the keyword and competitor info:Optimize this existing brief: [paste brief]
Click Save then Publish (to "Only Me" — keep it private to your account)
Part 5: Test and Refine
- In the Preview panel, type:
Generate brief for: HVAC maintenance checklist - Check the output against your template — is the format correct? Is the word count section asking for data, or making up numbers?
- If something is off, go back to the Instructions and add clarifying rules
- Run 3-5 test briefs before using with real clients
Real Example: Generating a Brief in Under 10 Minutes
Setup: You've built your GPT with the instructions above and uploaded your template.
Input:
Generate brief for: "best email marketing software for nonprofits"
SERP data:
- Top 5 URLs: [paste URLs]
- Competitor word counts: 2,100, 1,800, 2,400, 1,600, 2,200
- PAA questions: [paste 5 questions]
- Related keywords: [paste 15 terms]
- Competitor gaps (they don't cover): grant tracking integrations, volunteer email segmentation
Output: A complete 10-point brief in 60-90 seconds
Time saved: 60-80 minutes of manual brief writing, reduced to 10 minutes of data collection + 2 minutes of review
What to Do When It Breaks
- Brief format keeps drifting → Add specific examples to your Instructions: "Here is an example of a perfect brief: [paste one of your best briefs]"
- Word count recommendations are off → Change your instruction to: "Always ask me for competitor word count data before recommending a target range. Do not estimate."
- Outlines are too generic → Add to Instructions: "Outlines must reflect the specific topic's nuances. Do not use generic H2s like 'Benefits of [topic]' or 'How to Choose [topic]' without specific content substance."
- GPT ignores the format → Move your format to an uploaded file rather than inline instructions — uploaded files often get better adherence
Variations
- Simpler version: Use Claude Projects (Level 3) with your brief template loaded — no build required, but you re-explain format less often
- Extended version: Add client-specific knowledge files so the GPT knows your top 10 clients' industries, brand voices, and competitor lists by name
What to Do Next
- This week: Build and test the GPT; run 5 real briefs through it
- This month: Share the GPT link with any content team members or VA who writes briefs
- Advanced: Add a Zapier step that triggers brief generation when a new keyword is added to your content tracking spreadsheet
