Keyword Density Checker
Keyword density is the percentage of times a keyword appears compared to the total word count. A 1,000-word page mentioning a keyword 10 times has 1% density. Most SEO guidance says 1-2% is a reasonable range, though the concept has less weight now than it did in early search engine optimization.
SEO, GEO & AEO: why this checklist matters
Who should use this
Writers reviewing drafts for keyword balance, SEOs auditing existing pages, and editors checking content before publication.
Rankings, AI answers, and citations
Modern search engines don't use keyword density as a direct ranking factor. They understand topical relevance through semantic analysis. But checking density is still useful for editing: it tells you whether you've used your primary keyword naturally throughout a piece or stuffed it into the introduction and nowhere else.
What to verify before you ship
- Check target keyword, primary variations, and key synonyms separately
- Aim for natural distribution across the page, not front-loaded repetition
- Flag any keyword over 3% density for review — it may read as stuffing
- Use density check as an editing sanity check, not a target to hit

What is the ideal keyword density?
There isn't a universal number. 1-2% is often cited as a practical range for primary keywords. What matters more is natural usage that makes sense to readers, not hitting a specific percentage.
Does Google still use keyword density as a ranking factor?
Not in the way it did in early 2000s SEO. Google's algorithms now assess topical relevance through semantic analysis. Keyword density is more useful as a writing quality check than as a ranking strategy.
What should I do if my density is too low?
Check whether you've used synonyms and variations without the exact match keyword. If the page genuinely covers the topic, low density may not be a problem. If the keyword is missing from key places like the title, headings, and first paragraph, add it naturally.
What if my density is too high?
Replace some instances with synonyms or restructure sentences to use the concept without repeating the keyword. Read the page aloud — if it sounds repetitive, it reads as keyword stuffing.
