You start by entering a seed keyword and related subtopics. The tool uses that to generate a set of keyword clusters, each grouped by similarity or search intent.

Each cluster includes related keywords that can be used to support a single blog post, landing page, or subtopic. This makes it easier to decide what to cover in one piece of content and what should be broken into separate articles.

For example, if you input “email marketing”, you might get clusters like:

• Tools for email marketing
• Email subject line tips
• Automation strategies
• B2B vs B2C email tactics

Keyword clustering is one of the most effective ways to build topical authority and improve SEO performance. Search engines are moving away from just matching keywords—they now look at how well your content covers a topic. Clustering helps you do exactly that.

Here’s how it helps:

• Saves time: Skip manual sorting and get clusters in seconds.
• Improves SEO: Builds stronger topic coverage and better internal linking opportunities.
• Simplifies content planning: Know what to write about and how each piece connects to your larger strategy.
• Boosts relevance: Each cluster reflects how people actually search, helping your content match real intent.

If you’re planning a content strategy or optimizing a website, this tool is a shortcut to better structure and performance.
