What can I do with a SERP-based keyword clustering tool?

How does the keyword clustering tool work?

Do I need to get search volume data from separate tools?
This tool focuses on clustering based on search result similarity. For search volume data, you would need to use other keyword research tools like Google Keyword Planner, Ahrefs, or SEMrush.
How many keywords can I group at once?
The free version allows you to cluster up to 200 keywords at once. The paid version can handle up to 20,000 keywords in a single clustering operation.
Can I export the keyword clusters to use in other tools?

What is minimum SERP overlap?

Some keywords are missing from the output file I received?
Keywords might be missing if they couldn't be processed (no search results found) or if they were filtered out during the clustering process. Check for typos or try adjusting your overlap settings.
Is there any support available if I have questions or issues with the tool?
Yes, we provide general website support chat for free users and dedicated clustering support for paid subscribers. You can reach out through our support channels for assistance.
