Topic cluster is basically a list of content assets on your website around a bigger topic.
Here’s an example,
Let’s say you are writing a post on ” What is SEO ” in that post you explained all about SEO and all of it’s main aspects.
So that’s your pillar page, a broad topic page.
Now your topic cluster pages will cover other elements of SEO like:
On-page SEO Off-page SEO Technical SEO
All of these topics are a part of a broad topic which is SEO.
So that’s what topic clusters mean.
They’re important because they help Google understand your expertise on a certain topic, it’ll help you rank better, if you answer everything about a topic in your posts.
You kinda become a legit source. If you need help create content for you cluster pages, you can always use AI like [shopia.ai](https://shopia.ai) , writesonic or [jasper.ai](https://jasper.ai)
