Automatically group keywords into topical clusters, in minutes
KeyClusters is a focused SERP-based keyword clustering utility: particularly strong for pay-as-you-go research and regional/device-specific grouping, but not a full SEO execution or measurement suite.
KeyClusters is a pay-as-you-go keyword clustering tool that uploads keyword files, runs each keyword through Google, analyzes the top 10 ranking pages, and groups keywords when three or more ranking pages are shared. It returns the result as a downloadable CSV or Excel-style report and supports geography and device targeting.
Good fit for SEO professionals, consultants, content teams, and agencies that need SERP-based keyword grouping for content planning, cannibalization checks, or large audits without a recurring subscription
Pay-as-you-go credit packs; no subscription or recurring charge. One credit equals one keyword, and credits never expire.

Scorecard
1.8/5 overall, weighted for SEO research tools. How grades work.
Deep live-SERP clustering for an uploaded keyword set, without seed expansion, backlinks, or broader market research.
KeyClusters analyzes the top ten Google results for supplied keywords and groups terms by overlapping ranking pages. https://www.keyclusters.com/
Strong grouping of an existing keyword set, but not documented as a keyword-discovery suite.
The product accepts Ahrefs, SEMRush, or custom keyword files and returns topical groups; it does not advertise seed expansion or keyword-volume discovery on the homepage: https://www.keyclusters.com/
Captures SERP, geography, language/file, and device context, with limited broader business context documented.
The official feature list documents any geography and desktop/mobile analysis plus Ahrefs/SEMRush/custom uploads: https://www.keyclusters.com/
Competitor context
Competitor context is available indirectly through SERP ranking-page overlap and a comparison article, not as a dedicated competitive dashboard.
Provides planning signals, not documented content production.
The homepage says clusters indicate which pages to create and how to interlink them, but does not describe writing or brief-generation features: https://www.keyclusters.com/
No product capability for AI-search or generative-engine visibility is documented.
The official product feature list describes Google SERP clustering, exports, geography, and device targeting, not AI-overview or generative-engine measurement: https://www.keyclusters.com/
No technical crawl, performance, schema, or site-audit function is documented.
The homepage scope is keyword upload, SERP analysis, clustering, and export; it does not claim technical SEO auditing: https://www.keyclusters.com/
No CMS connection or publishing workflow is documented.
The documented output is a CSV/Excel-style keyword grouping file, with no CMS publishing integration described: https://www.keyclusters.com/
No ongoing rank, traffic, conversion, or experiment tracking is documented.
The official product page describes one-off clustering jobs and file output rather than monitoring or KPI dashboards: https://www.keyclusters.com/
A documented API and automated clustering flow provide some machine access, but autonomous agent controls are not documented.
The official comparison article says an API with token authentication is available and describes upload-to-cluster automation: https://www.keyclusters.com/blog/keyword-clustering-tools-comparison
Agentic workflow coverage
Low-entry, usage-based pricing and non-expiring credits make burst usage accessible.
Public packs start at $19 for 2,500 keywords, with no subscription and no credit expiration: https://www.keyclusters.com/
The site makes a broad first-party popularity statement but supplies no verifiable customer count.
The official comparison article says 'Join thousands of SEO professionals'; this is a marketing claim, not a customer-count breakdown: https://www.keyclusters.com/blog/keyword-clustering-tools-comparison

Grounds clusters in live Google SERP results and supports imported Ahrefs/SEMRush keyword files.
Third-party app grounding
Supports Ahrefs and SEMRush export files, but native live app integrations are not documented.
Custom API grounding
The official comparison article says a REST API with token authentication is available.
Geographic SERP targeting is not generative-engine optimization support.
KeyClusters documents Google SERP clustering by country and device, but no AI-answer citation or GEO workflow. https://www.keyclusters.com/

Autonomous execution
It automatically fetches and analyzes SERPs after the user uploads keywords, but does not autonomously execute content or SEO changes.
Human control and review
The user controls file upload, geography/device choices, and credit purchases; formal review/approval controls are not documented.
Integration surface
The product documents CSV/custom uploads, Ahrefs and SEMRush support, file export, and an API.
Memory and persistent context
Persistent non-expiring credits are documented, but reusable project memory or organizational context is not.
Evaluation and feedback loop
No evaluation, feedback, model-tuning, or result-quality feedback loop is documented.
Clustering itself is automated after upload, but file preparation and workflow decisions remain user-led.
The homepage documents a three-step user flow—upload keywords, analyze SERPs, get results—rather than an autonomous end-to-end SEO workflow: https://www.keyclusters.com/
No permanent free tool or free tier is documented on the pricing section.
The official pricing table lists three paid credit packs and says every credit pack includes full feature access; it does not list a free tier: https://www.keyclusters.com/
