Frequently Asked Questions
What is keyword density?
Keyword density is the percentage of times a keyword appears relative to total words. It helps you avoid keyword stuffing while ensuring adequate keyword use.
What is the ideal keyword density for SEO?
Generally 1-3% is considered optimal. Below 0.5% may be insufficient; above 4% may look like keyword stuffing to Google.
Does keyword density still matter for SEO in 2025?
Yes, but less than before. Natural usage, semantic relevance, and topical coverage matter more than hitting an exact density figure.
Why are short words excluded from the frequency table?
Words of 1-2 characters (articles, prepositions) are filtered out as they are rarely SEO-relevant.
Is my text stored when I use this tool?
