How does clustering work in SEO?
Good Question!

Clustering in SEO means building a main "pillar" page around a broad topic, then linking it to related, detailed content (cluster pages). This helps search engines see your site as an authority, boosting rankings!
 
In SEO, clustering involves grouping related content around a central topic (pillar content) to enhance site structure and boost search rankings. Here’s how it works:

  1. Pillar Page: A broad, comprehensive page that covers a core topic in detail.
  2. Cluster Content: Supporting pages or posts that explore subtopics related to the pillar page.
  3. Internal Linking: Each cluster page links back to the pillar page and vice versa, creating a web of related content.

Benefits:​

  • Improves SEO: Helps search engines understand content relationships, boosting rankings for related queries.
  • Enhances User Experience: Provides users with deeper, interconnected information on a topic.
  • Increases Authority: Establishes your site as a go-to resource for a specific subject.
By organizing content into clusters, websites can improve visibility and offer a better experience for users and search engines alike.

you don't need an image to understand clustering, you can google the images if you want, you'll find plenty of them :)

Basically, topic clustering (aka keyword clustering, aka pillar content, they're basically the same thing) means silo (or site structure if you prefer)...

And most clusters (silos) are just pyramids of pages, something like this...

TOPIC PAGE > Sub-topic page > Sub-sub-topic page > Sub-sub-sub-topic page... etc...

Although, to be honest, for small / medium size sites (sites with dozens to 100s of pages, that's what I call small / medium size) clusters are only 1 level deep usually (so, TOPIC PAGE > Sub-topic page, you almost never see small sites with content that's 2-3 levels deep)

For example, let's say that your site is about cars, and the 3 most important keywords that you wish to rank for are:

- car parts shops
- car care services
- car retailers

You find these 3 keywords that you really like and then you plop them into Ahrefs / Semrush (or whichever keyword research tool you use) and - to your disappointment - you see that all 3 these keywords are very hard to rank for (they have high search volume and high keyword difficulty, something like 50+ KD score in Ahrefs).

So what do you do in this case when 1 single page on each keyword might not be enough to rank you because of the high competition (remember, in SEO high search volume is almost always equal to high competition regardless of what the SEO tools say)?

Well, you use keyword clustering (siloing, topic clustering, etc... again, these terms mean the same thing more or less, so I'm using them interchangeably in this post...

So, you use each one of these keywords as topical clusters by making one "pillar page" for each keyword (just like you would normally do anyway for most sites), but instead of making just 1 page for each keyword like you would normally do and then build links to that page you are instead making one page for each keyword, but then you go back to Ahrefs / Semrush and find at least a few more keywords that are relevant to each topic and write content on those keywords too and link to the page of the main keyword that these relevant keywords support.

Something like this...

car parts shops > car parts shops by location
car parts shops > car parts shops by car make
car parts shops > car parts shops by component

car care services > car painting services
car care services > car washing services
car care services > tire changing services
car care services > oil changing services
car care services > engine checking services
car care services > car maintenance services

car retailers > car retailers for used cars
car retailers > car retailers for new cars
car retailers > car retailers for sports cars
car retailers > car retailers for limos

Of course, these examples might look a bit silly because if intend to have a page titled "Car Parts Shops by Location" you're not going to turn into a stupid blog post talking about locations for car shops. You can still do that if you want (you'd probably even find enough info to make a decent post), but you would not fulfill the intent of the keyword because people who search for car shops and mention the word "location" in their search are almost guaranteed to want to find actual shops in whichever location they're searching for.

So, in this case, both google and your users would love if you'd put a map or something on this page, that let's people find car shops in the location of their choice instead of boring them to death with information about car shop locations :)

So yeah, use your common sense and judgement when you come up with the right silo for your site and the right structure and clusters for your content and you'll be able to make a great site... hopefully...

Hey!

I just found this forum and saw your reply, Tazarbm. I wanted to thank you for the great value you provided in just a 2-minute read. I’m 2 weeks into learning SEO, and your explanation of clustering was simple and clear. Thanks a lot!

re-reading that post now I am actually scratching my head because I didn't explain as well as I would have wanted, but I guess that's the toll being non-English speaker takes on me (I can't convey ideas properly). But... if you understood the main points that's all that matters :)

And no problem, I love explaining things simply despite of the fact that business people and "experts" like to complicate them unnecessarily in order to appear to be gurus or something....
 
Clustering in SEO, also known as topic clustering, is a strategy used to organize content around a central topic or theme in a way that improves a website’s structure and search engine rankings.
 
Clustering in SEO involves creating groups of content around a central theme. A pillar page serves as the main hub, targeting a broad topic, while cluster pages focus on specific, related subtopics and link back to the pillar. This approach improves search engines' understanding of your site's content hierarchy. It strengthens topical relevance, boosts rankings for related keywords, and enhances user experience by providing well-organized, in-depth information.
