What a keyword map is
A keyword map is a record of which page owns which search term. In its simplest form it is a table:
| Keyword | Owning page | Intent | Notes |
|---|---|---|---|
| keyword mapping | /guides/keyword-mapping/ | Informational | Primary |
| what is keyword mapping | /guides/keyword-mapping/ | Informational | Secondary |
| sitewide content plan | /keyword-universe-mapping/ | Commercial | Primary |
That is the whole artefact. Its value is not in the format — it is in the rule attached to it: before targeting a term, check the map. If it is owned, do not target it again.
Without that rule, the same term gets targeted repeatedly, by different people, months apart, and nobody notices until rankings start wobbling.
Why it is worth the effort
It prevents cannibalisation at the cheapest possible moment. Fixing cannibalisation afterwards means merging pages, redirecting URLs and losing some of what they earned. Preventing it costs one lookup before writing.
It makes internal linking decidable. If you know which page owns "keyword mapping", you know which page every mention of that phrase should link to, and the anchor text writes itself. Without a map, internal links get pointed at whichever page the writer remembered.
It exposes gaps and overlaps. Terms with no owner are opportunities. Services with no supporting term are pages nobody can find.
It survives staff changes. The knowledge of what targets what is usually in one person's head. A map is that knowledge written down.
Building one
1 · List the pages that can rank. Service pages, product pages, articles. Not privacy policies or thank-you pages.
2 · Find what each already ranks for. Search Console, Performance → Pages, filtered per page. This is the honest starting point: what the page *actually* earns, not what it was intended to target. The two often differ, and where they differ the data usually wins.
3 · Assign one primary term per page. One. The page's job in a sentence. If you cannot choose, the page is probably trying to do two jobs and should be two pages.
4 · Add three to five secondaries. Variations and closely related questions the same page can reasonably answer.
5 · Record the intent. Informational, commercial, transactional. This is what stops a buying query being assigned to a blog post.
6 · Note what has no owner. That list is your content plan.
The exercise usually takes an afternoon on a small site, and the second step is the one that surprises people — pages frequently rank for something nobody chose.
When two pages claim the same term
This will happen on any site with history. The resolution order:
- Which page does Google already prefer? Search the term with
site:yourdomain.comand see which comes up. Arguing with an existing preference is expensive. - Which page matches the intent better? A buying query belongs on a commercial page even if a blog post currently ranks.
- Which page earns more? Traffic, conversions, links.
Then assign the term to one page, and re-target the other — a different angle, a different stage, a different question. Re-pointing its internal links matters as much as rewriting its title.
If the two pages genuinely say the same thing, merge them. That is a cannibalisation fix rather than a mapping one, and it is covered in the cannibalisation guide.
Keeping it current
A map that is not maintained becomes wrong, and a wrong map is worse than none because people trust it.
Three habits:
- Update it in the same pass as publishing. Not "later". Later does not happen.
- Review it when rankings shift. If a page starts ranking for something unexpected, that is information — either update the map or fix the page.
- Re-check it before any restructure. A migration with a current map is a different exercise from one without.
On a small site a spreadsheet is entirely adequate. The tooling is not the point; the discipline is.
Frequently asked questions
What is keyword mapping in SEO?
Assigning each target keyword to exactly one page and recording it, so no two pages compete for the same term. The record is usually a simple table of keyword, owning page and intent.
How many keywords should one page target?
One primary term plus three to five closely related secondaries. If a page needs two genuinely different primary keywords, it is usually trying to do two jobs and should be two pages.
What if two pages already rank for the same keyword?
Check which one Google already prefers with a site: search, which one matches the intent, and which earns more. Assign the term to that page and re-target the other at a different angle, including re-pointing its internal links.
Do I need a tool for keyword mapping?
No. A spreadsheet is adequate for most sites. The value is in the discipline of checking before publishing, not in the software — a tool nobody updates is no better than no map.
Get the whole site mapped in one pass
Building a keyword map from scratch is an afternoon on a small site and a much larger job on one with years of accumulated content — which is exactly the situation where cannibalisation has already crept in and nobody has a full picture.
The Sitewide Keyword & Content Plan maps every page to the terms it should own, with the gaps and overlaps identified — $697, one-off, no retainer.
