How to Clean a Keyword List Before Using SEO Tools

Why this matters

Most SEO tools charge by query volume, row count, or project size. Cleaning the list first helps you avoid wasting checks on repeated keywords. It also makes clustering and manual review faster because similar terms appear near each other after sorting.
