Keyword Cluster is a free Chrome extension that turns Google and Bing search results into keyword clusters, long-tail keyword variations, and search intent insights for SEO professionals.
What is Keyword Cluster?
Keyword Cluster is a lightweight Chrome extension that automatically groups related search queries into keyword clusters using AI. It takes any search query on Google, Bing, or YouTube as input and displays clusters, long-tail keyword ideas, and intent categories directly in the search results page. The extension is developed by keywordcluster.net and requires no account or login to use.

- Plan content around topic clusters: Use the topic groups shown on the SERP to decide which subtopics to cover in a pillar page or content hub.
- Analyze competitor search results: Search a competitor’s target keyword and view the clusters generated from the same search data to identify content gaps.
