SEO content briefs using Claude.

Most AI content briefs produce 3,500-word generic content. Here's how to beat that.

Watch any AI-content tool generate a content brief and you'll see the same pattern. Hit "generate," get a 3,500-word "comprehensive guide" recommendation, with 27 H2s, and a TL;DR. The brief is bloated because the tool thinks comprehensive is the strategy.

Comprehensive is the loser's strategy. The post that ranks isn't the post that hits everything, it's the post that hits one specific gap that the top 10 don't cover well. Here's the prompt setup that produces that brief instead.

Where you're wasting writer time

A 3,500-word brief produces a 3,500-word post that competes with 3,500-word posts already ranking. You've added effort without adding differentiation. The writer spends 8 hours producing something the SERP already has.

A 1,200-word brief that names the specific gap to beat on produces a piece that has a real shot. The work shifts from "cover everything" to "beat on one thing." Faster to write, more likely to rank.

What a good SEO brief actually needs

The brief is the working document. It has to do five things:

  1. Name the dominant search intent and the sub-intents
  2. Show the consensus structure across the top 10 (so the writer matches table stakes)
  3. Identify the specific content gaps to beat on (the only part that matters)
  4. Specify the expertise signals required (first-person screenshots? Named example?)
  5. Include a "what NOT to write" section, what to skip, even though everyone else covers it

Most AI briefs do (1) and (2) and call it done. Without (3), (4), and (5), the brief is a template, not a strategy.

The SERP-Informed Brief Writer prompt

The SERP-Informed Brief Writer is one of the four free prompts. The full prompt is on that page. The key moves built into it:

It refuses to guess at SERP content. If you don't paste in the top 10, Claude refuses to write the brief. The whole value is grounding in real SERP content, not generic SEO heuristics.

It includes an anti-comprehensive clause. "Don't recommend comprehensive briefs. Comprehensive is the loser's strategy." That single line changes the entire output shape.

It mandates a "what NOT to write" section. Most briefs only tell you what to include. This one explicitly lists what to skip, usually 4-5 moves the top 10 all make that you should refuse.

It marks inferred consensus claims. The "8/10 results include a definition" line is grounded in the excerpts you pasted. If Claude only saw 5 results, it says so.

How to actually run it

Step 1, gather the inputs

Three things you need before pasting anything:

  1. The target query, exact wording, the way a user would type it.
  2. The visible body content of the top 10 results. Not just titles. The actual sections, headings, key sentences. Grab the headline, the first 200 words, all H2s, and any unique content moves (calculators, tables, embedded videos).
  3. Your site context, one sentence about what your site is, and any related content you've already published (so Claude doesn't recommend topics you've covered).

Step 2, paste it all into Claude

Paste the SERP-Informed Brief Writer prompt first. Then your three inputs. Hit go. You'll get back a structured brief in about 30 seconds.

Step 3, verify the consensus claims

Before sending the brief to a writer, spot-check the "consensus structure" section. Claude inferred those X/N counts from the excerpts you pasted. If something seems off, click into 2-3 of the actual results and verify. Five minutes of verification beats shipping a brief with a wrong premise.

Step 4, pressure-test the content gaps

The "content gaps no one covers well" section is where the brief earns its keep. For each gap, ask: is this actually a gap, or did Claude over-extrapolate from the excerpts? A real gap is one you can verify by checking the actual results. An imagined gap is the post failing before it's written.

Step 5, use the "must beat on" section as your QA checklist

When the writer (human or AI) delivers the draft, your only QA question is: did it beat on the gaps the brief identified? If yes, ship. If no, send it back with the brief attached. Don't accept a draft that hits table stakes but doesn't beat on anything.

When the SERP is unwinnable

Sometimes the brief comes back and says some version of "don't write this." That happens when the top 10 is dominated by Anthropic's own docs, the IRS, the NHS, or a 25-year domain. In those cases, the right move is a long-tail variant ("How to set up a Claude Project for marketing teams" instead of "What is Claude") or a content angle the entrenched results don't own.

An honest brief tells you when not to write the post. That's worth more than a brief that confidently tells you to write something that won't rank.

The receipts

I used this exact prompt to plan the SEO play behind the post you're reading. The brief identified that no result for "claude seo brief" covered the "what NOT to write" angle in depth. So that's what this post leans on. Whether it ranks is a 30-day question. But the strategy is documented and the brief is reusable.

That's the meta-proof play. Use the prompts that drive the product to drive traffic to the product.
