Frequently asked questions

Is the Keyword Cluster Tool free?
Free, unlimited, and no email address required. You can use it a hundred times a day and nothing changes.
Is the Keyword Cluster Tool safe to use with private information?
No. The Keyword Cluster Tool runs entirely in your browser using JavaScript. Because the work happens locally, the tool also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
What problem does the Keyword Cluster Tool solve?
The jobs it is built for: turning a 500-row keyword export into a content plan. Avoiding two pages that compete for the same query. Finding the head term for each group. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Will this work on a tablet?
Yes. The page is responsive and the tool works in Chrome, Safari, Firefox, Edge and Samsung Internet on both Android and iOS. There is no app to install and nothing to sign into.
