# Keep a keyword map from topic to one page

For AI agents: the [site map](https://agentwranglers.se/llms.txt) lists everything here, and this page sits under [Keyword research](https://agentwranglers.se/playbook/seo/keyword-research.md).

- Rule: Keep one keyword map that gives each primary phrase exactly one address. Check the map before you create any new page.
- Check: A test reads the map. No primary phrase appears twice, no address is the target of two primary phrases, and every address answers 200 in the built site.
- How: The map is a table with the phrase, its variants, its intent, its buying stage, the address and the date of the last review. Keep it in the repository next to the pages, so a build test can read it. Every new page starts as a row. When a phrase already has an address, improve that page instead of adding one. The map also plans internal links, as [Link every page from another](https://agentwranglers.se/playbook/seo/site-structure/internal-linking.md) says.

## Examples

**Using these examples:** they show one way to follow this rule. Keep the behaviour and the check, not the syntax. Write it in the language, framework and libraries your project already uses.

### JavaScript example

```js
const seen = { phrase: new Set(), path: new Set() };
for (const row of keywordMap) {
  assert.ok(!seen.phrase.has(row.phrase), `${row.phrase} is mapped twice`);
  assert.ok(!seen.path.has(row.path), `${row.path} has two primary phrases`);
  seen.phrase.add(row.phrase);
  seen.path.add(row.path);
}
```

### Python example

```python
phrases = [row["phrase"] for row in keyword_map]
paths = [row["path"] for row in keyword_map]
assert len(phrases) == len(set(phrases)), "a phrase is mapped twice"
assert len(paths) == len(set(paths)), "an address has two primary phrases"
```
