Keyword Mapping

Why Keyword Mapping Matters

Keyword research gives you a list of opportunities. Keyword mapping tells you what to do with them. Without a map, you risk:

• Cannibalization — Two pages competing for the same keyword, both ranking poorly
• Orphaned keywords — Valuable keywords with no page targeting them
• Duplicate effort — Creating content for a keyword you already cover
• Structural chaos — A site with no logical topical organization

According to Semrush, 50.3% of websites have at least one instance of keyword cannibalization (Semrush, 2024). This means half of all websites are actively hurting their own rankings by failing to map keywords properly.

Creating a Keyword Map Spreadsheet

Your keyword map is a spreadsheet with one row per page. Here are the essential columns:

Example Keyword Map

Primary vs. Secondary vs. LSI Keywords Per Page

Primary Keyword (One per Page)

Every page has exactly one primary keyword. This is the keyword that appears in:

• The title tag
• The H1 heading
• The URL slug
• The meta description
• The first 100 words of the content

Choose the highest-volume keyword in your cluster as the primary, as long as it accurately represents the page's content. Backlinko found that including the primary keyword in the title tag is correlated with higher rankings, although it is no longer a strict requirement (Backlinko, 2024).

Secondary Keywords (2-5 per Page)

Secondary keywords are variations and closely related terms from the same cluster. They appear in:

• H2 and H3 subheadings
• Body paragraphs (naturally, not forced)
• Image alt text
• Internal link anchor text pointing to this page

According to Surfer SEO, pages that include 3-5 secondary keywords from the same cluster rank for 2.4x more total keywords than pages targeting only a primary keyword (Surfer SEO, 2024).

LSI and Related Terms (5-15 per Page)

LSI keywords are semantically related terms that help Google understand the depth of your content. You do not need to force them in. If you write comprehensively about a topic, most LSI terms appear naturally.

For a page about "how to make cold brew coffee," LSI terms might include: "coarse grind," "steep time," "water ratio," "room temperature," "concentrate," and "coffee beans."

Avoiding Keyword Cannibalization

Cannibalization happens when two or more of your pages target the same keyword. Google does not know which to rank, so it often ranks neither well or alternates between them unpredictably.

How to Detect Cannibalization

1. Search Console check: In GSC, filter by a keyword and see if multiple URLs appear. If two pages get impressions for the same query, you have cannibalization.
2. Site: search: Google "site:yoursite.com keyword" to see which pages Google associates with that keyword
3. Ahrefs/SEMrush: Use the Organic Keywords report filtered to a specific keyword. If multiple URLs from your domain appear, they are cannibalizing.

How to Fix Cannibalization

• Merge content: Combine the two pages into one comprehensive page and redirect the weaker one
• Differentiate intent: If the pages serve different intents, adjust their primary keywords to be distinct
• Canonical tag: Point the less important page's canonical to the main page
• Noindex: If one page has no SEO value, noindex it to remove it from competition

Moz documented a case study where fixing cannibalization across 10 keyword groups increased organic traffic by 32% within 3 months (Moz, 2024). The traffic was always available; it was just being split between competing pages.

Mapping to Existing Content vs. New Content

Your keyword map should account for both existing pages and planned pages:

For Existing Pages

1. Audit your current pages: what keywords do they already rank for?
2. Assign the most relevant cluster to each existing page
3. Identify gaps: are there secondary keywords the page should target but does not?
4. Update content to better cover the full cluster

HubSpot found that updating existing content to target a full keyword cluster increased organic traffic to those pages by an average of 106% (HubSpot, 2024).

For New Content

1. Identify clusters with no matching existing page
2. Prioritize by: volume potential, KD feasibility, business relevance
3. Plan the content type based on intent
4. Schedule creation in your content calendar

Mapping Keywords to Funnel Stages

A complete keyword map covers every stage of your marketing funnel:

Demand Gen Report found that 67% of B2B buyers consume at least 3-5 pieces of content before engaging with a sales rep (Demand Gen Report, 2024). Your keyword map should ensure you have content at every stage they might visit.
