**A Perplexity-powered content brief does three things a keyword tool can't. It shows the sub-questions an answer engine breaks your topic into. It shows which sources Perplexity cites for each one today. And it shows where those sources are thin, outdated or missing your point of view. Build the brief around those gaps, add evidence only you have, and you have a page built for both Google and answer engines.**

> **Key takeaways**
>
> - Start from the buyer question. Ask Perplexity to break it into sub-questions, then check each one.
> - Audit the current citations: who is cited, for what passage, and how fresh.
> - Brief around the gaps: missing data, outdated facts, missing comparisons and missing perspectives.
> - Every brief needs an "original evidence" section, because that's what you'll be cited for.

## What does the brief template look like?

| Section | Content | Where it comes from |
|---|---|---|
| Target question | The buyer's question, in their words | Sales notes, Search Console, voice-of-customer quotes |
| Demand signal | Impressions, keyword volume, prompt-set inclusion | Search Console, keyword tool, your prompt set |
| Sub-questions | 6-12 questions the page must answer | Perplexity question breakdown |
| Current citations | Who Perplexity cites for each sub-question | Perplexity Search and Pro Search |
| Gaps | What the cited sources miss or get wrong | Your audit |
| Original evidence | Data, examples and expert quotes only you have | Product data, customers, SMEs |
| Structure | H2s as questions, answer-first paragraphs, tables | Lesson 15 patterns |
| Internal links | Hub, siblings, product pages | Your site map |
| Refresh date | When the facts need rechecking | Your content calendar |

## How do you map sub-questions?

Prompt:

```
A mid-market finance manager asks: "How do I reduce duplicate invoice payments?"
List the 10 sub-questions a complete answer must cover, ordered as a buyer would think through them. For each, say whether it is definitional, how-to, comparison, cost, or risk.
```

Then check coverage: run the main question in Pro Search and look at which sub-questions the answer covers and which sources it uses for each.

*Our view:* the sub-questions are your H2s. Pages structured around the questions engines actually decompose into are easier to retrieve passage by passage. That's the whole idea behind [answer-first content](https://mentionx.ai/learn/content/write-answer-first-content-llms-quote).

## How do you audit the current citations?

For the main question and each important sub-question:

1. Run it in Search and Pro Search.
2. Record every cited URL, its type (vendor, publisher, community, review, docs), its date, and the passage that seems to be quoted.
3. Ask: "For each source you cited, what specific claim did you take from it?"
4. Ask: "What information did you look for but could not find a good source for?"

That last prompt is the most useful brief prompt we know. It often surfaces missing data that would make your page the obvious source.

Use a table like this:

| Sub-question | Cited sources | Freshness | Gap |
|---|---|---|---|
| What causes duplicate payments? | Publisher A, Competitor B blog | 2024, 2025 | No data on frequency by company size |
| How do AP tools detect duplicates? | Competitor A docs | 2026 | Only one vendor's method explained |
| What does it cost? | None | | Nobody publishes recovery costs |

## How do you turn gaps into a brief?

Gap types and what to do:

| Gap | Brief instruction |
|---|---|
| Missing data | Commission a small analysis from product data, or survey customers |
| Outdated facts | Publish the current version with a visible "updated" date |
| One-vendor view | Write a neutral comparison of methods, including your own |
| No worked example | Add a step-by-step example with screenshots described in text |
| No definition | Add a two-sentence definition block near the top |
| Unanswered "cost" question | Add a cost table with assumptions shown |

> **Pro move:** for every gap, write the one sentence you want Perplexity to quote, before anyone drafts the article. For example: "In Ledgerline's 2026 customer data, most duplicate payments came from vendor records with two remittance addresses." If you can't write that sentence, you don't have original evidence yet.

## How do you add the SEO layer?

Perplexity doesn't show search volume. Pair it with:

- **Search Console.** Queries already sending impressions to related pages ([Search Console for Marketers](https://mentionx.ai/learn/search-console/search-console-for-marketers)).
- **Keyword data.** Volume and difficulty from your SEO tool.
- **SERP check.** Does Google show an AI Overview, and who is cited there?

A good brief targets one main query with clear demand, covers the sub-questions in depth, and includes evidence the current citations lack.

## How do you speed this up with a Project?

Create a "Content briefs" Project with:

- **Instructions:** your brief template, source rules, house style, and "never invent statistics".
- **Files:** product fact sheet, approved claims list, persona notes and the internal linking map.
- **Threads:** one per brief, named with the target question.

Then each brief starts with: "Brief for: [question]. Follow the template." After 20 minutes of checking, you have a draft brief.

For volume, you can automate the citation audit with the Search API or the Agent API and n8n, so the brief arrives with a sources table already filled in ([lesson 12](https://mentionx.ai/learn/perplexity/perplexity-n8n-automation)).

## Worked example: Ledgerline

*Ledgerline is a fictional accounts-payable software company. Details are illustrative.*

Ledgerline wanted a page for "how to reduce duplicate invoice payments". Perplexity's current answer cited Competitor B's blog, a publisher article from 2024 and Competitor A's docs.

| Brief element | Ledgerline decision |
|---|---|
| Target question | "How do I reduce duplicate invoice payments?" |
| Sub-questions | 9 (causes, detection methods, prevention controls, cost, tools, process, KPIs, audit, recovery) |
| Biggest gap | No source quantifies causes by company size |
| Original evidence | Anonymised analysis of duplicate-flag reasons across customers, approved by legal |
| Format | Answer-first intro, a definition block, a causes table, a step-by-step process and a cost table |
| Internal links | AP automation hub, three-way matching glossary, vendor master data guide |

### Walkthrough

1. Ran the sub-question prompt and kept 9 of the 10 suggestions.
2. Ran Pro Search on the main question and four sub-questions, and logged citations.
3. Asked "What could you not find a good source for?" The answer was cost of recovery and causes by company size.
4. Briefed the data team for a small anonymised analysis.
5. Wrote the quotable sentence for each gap before drafting.
6. Added Search Console data, where the query family already had impressions on an older post, so the plan was to update and redirect rather than create a duplicate page.
7. Set a 90-day refresh date.

## Common mistakes

- **Letting Perplexity write the article.** You'll publish a summary of the existing sources, which gives nobody a reason to cite you.
- **Skipping the "could not find" prompt.** It's where your best angle usually is.
- **Ignoring freshness.** If the cited sources are from 2024, an updated, dated page has an edge.
- **Creating duplicates.** Check Search Console for existing pages first.

## Try it yourself

Pick one question from your list of ten. Run the sub-question prompt, audit citations for the main question and three sub-questions, and run the "could not find" prompt. Write one quotable sentence for each gap. That's 80% of a brief.

## Quick quiz

**1. What's the most useful prompt for finding a content angle?**

*Answer:* "What information did you look for but could not find a good source for?"

**2. Where do your H2s come from?**

*Answer:* The sub-questions the topic breaks into.

**3. What must every brief include to earn citations?**

*Answer:* An original evidence section, with data, examples or expertise only you have.

## What should you check before the next lesson?

- Your brief template includes current citations and gaps.
- A "Content briefs" Project exists with house rules.
- One brief is complete with quotable sentences.

## Common questions

**Should Perplexity write the article itself?** Use it for research, structure and source gathering. Write the article with your own expertise, data and examples, because original evidence is what earns citations.

**Does a Perplexity brief replace keyword research?** No. Pair it with Search Console and keyword data for demand. Perplexity adds the question structure and shows which sources answer engines already trust.

**How long should a brief take?** About 30 to 45 minutes once your template and Project are set up.
