Keyword Density Checker
See which words appear most often in your text and how often.
Paste an article, blog post or landing page and this tool tallies how often each word appears, ranking them by frequency and showing each word's share of the total. It is a quick way to see which terms dominate a draft and whether the topic you meant to write about actually shows up. The analysis runs in your browser — the label notes it handles up to around 50,000 words locally — so nothing you paste is uploaded.
What it counts
The tool lowercases your text, splits it into words at spaces and punctuation, and keeps only words longer than two characters. It then counts how many times each one appears and shows the top 100 in a table with a Frequency and a Distribution % — that percentage is the word's count divided by the total number of counted words, to two decimals. The summary shelf reports the Core Word Count (total words counted), the Primary Term (the single most frequent word), and the Peak Density (that word's share, to one decimal).
Single words, and common ones are kept
Two things shape the results. First, it measures single words only, not two- or three-word phrases — so a target phrase like "meal prep" is counted as "meal" and "prep" separately, never as one item. Second, apart from dropping one- and two-letter words, it does not remove stop words, so everyday filler like "the", "and", "you" and "for" often sits right at the top of the list. Read past those to find the meaningful terms; the Primary Term is frequently just the commonest function word rather than your actual topic.
Reading density sensibly
Keyword density is a descriptive measure, not a lever you should optimise toward. There is no magic percentage that search engines reward, and writing to hit a number — the habit known as keyword stuffing — reads badly and can work against you. The genuinely useful signal here is proportion: whether the term you care about barely appears, or whether one word so dominates that the piece feels repetitive. Use it as an editing sanity check. This is indicative guidance, not professional SEO advice.
Frequently Asked Questions
Does it count phrases or only single words?
Only single words. A two-word phrase is split and each word counted separately, so it will not report "keyword density" for a multi-word term. Words of one or two letters are ignored entirely.
Why are words like "the" and "and" at the top?
It does not filter stop words beyond the one- and two-letter cut, so common function words naturally rank highest by raw frequency. Scan further down the list for the terms that carry meaning.
How is the density percentage worked out?
Each word's count is divided by the total number of counted words and multiplied by 100, shown to two decimals. Peak Density is the single most frequent word's share, shown to one decimal.
Is there an ideal keyword density to aim for?
No. There is no threshold search engines reward, and forcing a target hurts readability. Treat the numbers as a description of your draft, not a goal. All analysis happens in your browser.
