What is a Keyword Density Checker?
A keyword density checker measures how frequently words or phrases appear in a text and expresses that frequency as a percentage of total words. SEO writers and editors use it on drafts to ensure primary topics are clear, spot accidental repetition, and avoid over-optimization before publishing.
Our free online keyword density checker ranks the top terms in your paste with counts and density percentages. Switch between 1-word, 2-word, and 3-word phrase analysis, optionally ignore common stop words, and review up to 25 leading keywords from blog posts, landing pages, and product descriptions — all processed locally in your browser.

Keyword Density Tips
- •Density is a guide, not a rule: Modern SEO rewards relevance and readability — use percentages to inform edits, not hit fixed targets.
- •Check 2-word phrases: Long-tail pairs like "project management" often matter more than single-word counts alone.
- •Filter stop words for clarity: Turn on stop-word removal to keep "the" and "and" from dominating the top of your list.
- •Short copy skews percentages: Very short paragraphs produce volatile density figures — analyze full sections when possible.
- •Compare before and after: Run the checker on an old draft and a revision to see how edits shifted term frequency.
- •Pair with readability tools: Balanced keyword use should still read naturally — density checks complement, not replace, editing.

Frequently Asked Questions
What is keyword density?
Keyword density is the percentage of times a word or phrase appears relative to the total word count in a text. For example, if a 100-word article uses a term 5 times, its density is 5%.
What is a good keyword density for SEO?
There is no universal perfect percentage. Use density as a diagnostic — aim for natural language with clear topical focus. Extremely high repetition can signal over-optimization.
What are n-grams in this tool?
N-grams are contiguous word sequences. This checker supports 1-word (single terms), 2-word, and 3-word phrase analysis to surface repeated multi-word patterns.
What does the stop-word filter do?
When enabled, common function words such as "the," "and," and "is" are excluded from the ranked keyword list so more meaningful terms rise to the top.
How many keywords are shown?
The tool ranks and displays up to 25 leading terms or phrases with their raw counts and density percentages for the current settings.
Should I optimize only for one keyword?
Usually not. Strong pages cover a topic with related terms and phrases. Use 2- and 3-word n-gram views to see the broader vocabulary your draft emphasizes.
Is my SEO draft uploaded to a server?
No. Analysis runs entirely in your browser. Your unpublished copy never leaves your device.
Is the keyword density checker free?
Yes. Completely free with unlimited analysis and no registration required.
