What Is Keyword Clustering

Keyword clustering involves grouping keywords that are similar to each other together.

Essentially a “keyword cluster” is a group of keywords that mean the same topically and can be targeted together on a single page.

Upload your keyword list into Keyword Insights ® and we'll analyse the search engine result pages to group any keywords together where the ranking URLs are the same or similar.

Why Is Keyword Clustering Powerful?

Make your keyword research less daunting

Does your keyword research list contain thousands, if not hundreds of thousands of keywords?

Make the list more manageable by grouping similar keywords together quickly.

Optimise for more than 1 keyword

It’s so much easier (and organically rewarding) to create content that can rank for many low volume, low difficulty keywords than creating a piece targeting a single high volume keyword. Cluster your keywords and aim to rank for groups of keywords.

Make content production easier

One of the hardest things to do when creating new content is to know when a certain piece should be broken out into more specific sub-topics. Clustering via Keyword Insights ® makes this process quick and painless.

Keyword Insights ® actually analyses live search results pages and groups keywords based on whats ranking. So you’ll know very quickly when a page should be broken out into sub topics to stand the best chance of ranking.

Fix Cannibilisation Issues Quickly

Because we analyse live search result pages, we know if a a group of keywords should be targeted on the same page, or be split out into two separate pages.

Do you need different pages to rank for “properties for sale”, “houses for sale” and “homes for sale”? Find out quickly, and at scale, with Keyword Insight’s clustering insight.

See it in action

The clustering report KWI generates can be used to easily build topic clusters around parent keywords.

Our report will clearly show you what each page’s head keyword should be, whilst also listing other keywords that page can target.

Combine our cluster insight with our rank tracking feature and spot gaps or cannibilisation issues in your content quickly.

Sometimes similar keywords aren't so similar...

Keyword Insights ® can also show when keywords you thought were similar actually aren’t.

Let’s take the keywords “vape accessories” and “vape parts”. You’d be forgiven for thinking these basically mean the same thing. Consequently, you’d probably try and create a page that targets both terms. After all, that’s what most vape companies do.

And yet Keyword Insights ® has put “vape accessories” and “vape parts” in two different clusters (meaning they need two different pages).

Benefits of using Keyword Insights


Unlike other free options which rely on NLP to group keywords, we use live search result page data. This means we're grouping keywords based on what Google is, not what an algorithm thinks should be grouped.
