Keyword research for GEO is less about "finding a single keyword" and more about building a **question map** and an **entity checklist**.

If you do this properly, your pages become:

- easier to rank (classic SEO)
- easier to cite (GEO)
- more complete (covers fan-out)

---

## The shift: from keywords to questions + tasks

Traditional SEO often starts with keywords.

GEO-friendly research starts with:

- questions ("What is…", "How to…", "Which is better…")
- tasks ("How do I set up…", "How do I measure…")
- comparisons ("X vs Y", "best tools for…")

## Step 1: Choose a pillar topic

Pick a pillar you can realistically cover:

- [/resources/topics/ai-search-geo](/resources/topics/ai-search-geo)
- [/resources/topics/content-strategy](/resources/topics/content-strategy)

---

## Step 2: Build a fan-out question tree

Start with a seed query, then expand into:

- Definitions
- How it works
- Steps
- Pitfalls
- Measurement
- Alternatives
- Comparisons

Example for GEO:

- What is GEO?
- GEO vs SEO
- How do AI citations work?
- How to write cite-worthy content?
- How to measure AI visibility?

---

## Step 3: Build an entity checklist (the "must-cover" list)

Entity coverage means: if someone reads your page, do they get all the needed concepts defined?

For each page, list:

- key terms (GEO, citations, topical authority)
- related concepts (clusters, internal linking, freshness)
- tools/workflows (where relevant)

---

## Step 4: Prioritize with a simple scoring model

Use this lightweight scoring:

| Page idea                       | Business relevance (1–5) | Intent clarity (1–5) | Difficulty (1–5) | Total |
| ------------------------------- | -----------------------: | -------------------: | ---------------: | ----: |
| What is GEO?                    |                        5 |                    5 |                3 |    13 |
| Internal linking best practices |                        5 |                    4 |                3 |    12 |
| Programmatic SEO fundamentals   |                        4 |                    4 |                4 |    12 |

---

## Spreadsheet template (copy/paste)

Use these columns:

- Pillar
- Page title
- Target query
- Fan-out sub-questions (bullets)
- Required entities (bullets)
- Artifact type (checklist/table/template)
- Internal links (parent + siblings)
- CTA
- Status (draft / publish / refresh)

---

## Common mistakes

- Picking topics with unclear intent ("SEO growth")
- Writing without a fan-out plan
- Skipping entities and definitions
- Publishing pages that don't link into a cluster
