How Do You Do Keyword Mapping for a Website?

Keyword mapping is the process of assigning specific target keywords to specific pages on your website. Without it, you end up with pages competing against each other for the same keywords (cannibalisation), important keywords with no page targeting them (content gaps), and pages that have drifted from their original keyword focus over time.

Why do you need a keyword map?

Without a keyword map:

• Multiple pages drift toward the same keyword, cannibalising each other
• Content decisions are made without knowing which queries are already covered
• New pages are published without checking if a page already targets that keyword
• High-value keywords get missed because nobody specifically planned to cover them

A keyword map is the strategic document that makes your entire site's content intentional rather than accidental.

How do you build a keyword map step by step?

1. Audit your existing pages — create a spreadsheet listing every page on your site (use our Wayback URL extractor or export from Search Console)
2. Research your keyword universe — use Google Keyword Planner, PAA mining, and Search Console to build a comprehensive list of all queries relevant to your business
3. Group keywords by intent — keywords covering the same topic and intent belong on the same page, not separate pages
4. Assign each keyword group to a page — map each group to the most appropriate existing page, or flag it as a content gap requiring a new page
5. Identify cannibalisation — when multiple existing pages compete for the same primary keyword, choose one to keep optimised and consolidate or differentiate the others
6. Prioritise your content gaps — rank unmapped keyword groups by search volume and business relevance to create your editorial calendar

What does a keyword map look like in a spreadsheet?

A basic keyword mapping spreadsheet has these columns:

• Page URL — the full URL of the page
• Page type — homepage, service page, blog post, product page, category page
• Primary keyword — the main ranking target for this page
• Primary keyword monthly search volume — for prioritisation
• Secondary keywords — 3–5 related terms the page also targets
• Current ranking position — pulled from Search Console for the primary keyword
• Content gap flag — yes/no whether this keyword group has a suitable page

How many keywords should each page target?

Each page should have one clear primary keyword that defines its main ranking intent, plus three to five secondary keywords that are closely related and served by the same content. Secondary keywords are not separate topics — they are variations, synonyms, and closely related queries that a comprehensive page on the primary keyword would naturally address. A page targeting "keyword mapping" would also naturally rank for "how to map keywords", "keyword mapping tool", and "keyword mapping guide".

How do you use a keyword map day to day?

• Before publishing new content — check the keyword map to ensure the target keyword is not already assigned to an existing page
• During content audits — compare current Search Console rankings against assigned keywords to identify drift
• When planning new content — use the content gap flagged rows to generate your editorial calendar
• After site restructuring — update the keyword map to reflect any URL or page changes

Summary

• Keyword mapping assigns one primary keyword and secondary keywords to each page — preventing cannibalisation and ensuring coverage of all important queries
• Build your map by auditing existing pages, researching your keyword universe, grouping by intent, and assigning to pages
• Each page targets one primary keyword plus 3–5 closely related secondary keywords
• Use the map before publishing any new content to prevent accidental cannibalisation
• Review and update quarterly as rankings, content, and search demand evolve
