KeyClusters - 2026 Pricing, Features, Reviews & Alternatives

KeyClusters automates the keyword research process. The tool is built for SEO geeks and agencies, but can be used by any person looking to do intelligent keyword research for their website.

KeyClusters works in conjunction with major SEO tools like Ahrefs and SEMrush, to take their keyword insights and cluster them into topical groups.

Clustering 1000s of keywords would typically take many hours and is prone to lots of human error as some keywords that appear similar sometimes need separate articles and vice versa.

KeyClusters removes the heavy lifting and does this clustering analysis in minutes. Moreover, it also eliminates guesswork as the insights are generated from real-time Google data.

The tool takes all input keywords and runs them through the SERPs. It then analyses which keywords rank for which pages. If keywords have three or more pages ranking on page one in Google, it clusters them into a topical group. We know if three pages can rank for the same keywords, then we only need one article for those sets of keywords.

There is a little more logic to the tool that cross-references keywords and uses NLP analysis to tighten the output, but ultimately the result is a topical authority map of every keyword and related article you need to create to dominate a niche.
