How to Use the Comparison Keyword Tool (2026)
What it finds
The Comparison Keyword Tool is a free SEO keyword comparison tool. It expands your seed into comparison keywords (vs / or / better and more) from live Google autocomplete so you can compare SEO keywords the way people actually search.
How to run a search
- Open Comparison Keyword Tool.
- Enter a seed that matches your topic or product.
- Review suggestions, Keyword Score, and Hot Keywords.
- Apply Golden Filters to keep high-intent, manageable phrases.
- Map winners to titles, H2s, FAQs, or listing fields.
Filters & scores
Use word count, difficulty, relevancy, and autocomplete position together. A mid Keyword Score with strong relevancy often beats a generic head term you cannot rank or convert.
Where to use results
Build vs pages, roundups, and compare-and-contrast posts from your comparison keywords list. Pair with keyword ranking comparison in your usual tracker after you publish.
