Keyword clustering is how modern SEO actually works. Google doesn't rank pages for single keywords—it ranks pages for topic areas. Writing one thin page per keyword is the fastest way to cannibalise your own rankings. This tool groups your keywords into clusters so you know exactly which pages to create and which keywords belong together.

The old approach was simple: one keyword, one page. If you wanted to rank for "Sydney plumber", "plumber Sydney", and "plumbing services Sydney", you'd create three separate pages. The problem? Google sees these as the same search intent and will only rank one of your pages—meaning your three pages compete against each other instead of dominating the results.

What Keyword Clustering Is and Why It Replaced the One-Keyword-Per-Page Approach

Keyword clustering groups related keywords by semantic similarity and search intent. Instead of creating separate pages for "SEO cost Sydney", "how much does SEO cost in Sydney", and "Sydney SEO pricing", you recognise these share the same intent—someone researching SEO pricing in Sydney—and create one comprehensive page that targets all three.

This approach works because Google's algorithm has evolved. Modern search understands synonyms, variations, and context. A well-optimised page about SEO pricing in Sydney will naturally rank for dozens of related keyword variations without needing to force-fit each one into separate pages. The result is stronger topical authority, better user experience, and no keyword cannibalisation.

How to Use Clusters to Build a Content Strategy

Here's a practical example from a Sydney plumber's keyword research. After running keyword research, they have 40 keywords related to their services. Without clustering, they might create 40 thin pages. With clustering, those 40 keywords group into 8 clusters: emergency plumbing (transactional), blocked drains (transactional), hot water systems (commercial), plumbing cost (commercial), bathroom renovations (transactional), gas fitting (transactional), leak detection (informational), and plumbing maintenance tips (informational).

Each cluster becomes one page. The emergency plumbing cluster includes "emergency plumber Sydney", "24 hour plumber Sydney", "urgent plumbing Sydney"—all targeting the same intent. One comprehensive service page covers all these variations, ranks for all of them, and provides a better user experience than three near-identical pages. The content strategy is now clear: create 8 high-quality pages instead of 40 thin ones.

Topic Authority vs Keyword Targeting

Topic authority is Google's assessment of how comprehensively and authoritatively your site covers a subject area. Keyword targeting is the tactical execution—choosing which specific keywords to optimise for. Clustering bridges the two. By grouping keywords into topic clusters, you build topic authority while still targeting specific high-value keywords.

A site with 8 comprehensive, well-linked pages covering distinct topic clusters will outrank a site with 40 thin pages targeting individual keywords. The clustered approach signals to Google that you're an authority on the broader topic, not just chasing individual search terms. This is particularly important for Australian businesses competing in established markets like Sydney, Melbourne, and Brisbane where topical depth separates page 1 from page 3.

Frequently Asked Questions

What is keyword clustering in SEO?

Keyword clustering is the process of grouping related keywords by semantic similarity and search intent. Instead of creating separate pages for each keyword variation, you group related keywords into clusters and create comprehensive content that targets the entire cluster. This approach aligns with how Google ranks pages for topic areas rather than single keywords, helping you build topic authority and avoid keyword cannibalisation.

How many keywords should be in one cluster?

A typical keyword cluster contains 5-20 related keywords, though this varies by topic complexity. The key is that all keywords in a cluster should share similar search intent and could reasonably be answered by the same piece of content. For example, 'SEO cost Sydney', 'how much does SEO cost in Sydney', and 'Sydney SEO pricing' would cluster together because they share transactional intent and the same core topic.

Does keyword clustering help with AI Overviews?

Yes. AI Overviews favour comprehensive content that covers a topic thoroughly rather than thin pages targeting single keywords. By clustering keywords and creating in-depth content that addresses all related queries, you increase the likelihood of being cited in AI Overviews. Google's AI looks for authoritative, complete answers—which is exactly what keyword clustering helps you create.

How is keyword clustering different from keyword research?

Keyword research identifies which keywords to target. Keyword clustering organises those keywords into groups that should be targeted together on the same page. Research finds the opportunities; clustering determines your content structure. You do keyword research first to build your list, then use clustering to decide how many pages to create and which keywords belong on each page.

Should I create one page per keyword cluster?

Yes, generally. Each cluster represents a distinct topic or search intent that deserves its own dedicated page. The primary keyword becomes your target keyword, and the other keywords in the cluster are naturally incorporated throughout the content. This prevents keyword cannibalisation (multiple pages competing for the same rankings) and builds stronger topical authority for each subject area.
