Keyword Density Analyzer
Analyze keyword frequency and density in your content
About Keyword Density
Keyword density is the percentage of times a keyword appears compared to total words. Ideal density is 0.5-2.5%. This tool helps avoid keyword stuffing while ensuring proper optimization.
What is Keyword Density Analyzer?
The Keyword Density Analyzer is a free online SEO tool that counts how often each word and phrase appears in your content and shows it as a percentage of the total word count. Keyword density is simply the number of times a keyword is used divided by the total words, and the ideal range for most pages is between 0.5% and 2.5%. Paste any article, blog post, or landing page and the tool instantly reports total words, unique words, sentences, average word length, and reading time, plus your top terms across single words, 2-word phrases, and 3-word phrases (n-grams). Set a target keyword and the dedicated tracker shows its exact frequency and density with an ideal-range hint, and an optional stop-word filter hides filler words like "the" and "and" so meaningful terms surface. It runs entirely in your browser, so your content is never uploaded and there is no signup.
How to use Keyword Density Analyzer?
Analyzing the keyword density of your content takes only a few seconds:
- 1 Copy and paste your article, blog post, or web page into the content box. The tool works with any length of text, from a short product description to a long-form guide.
- 2 Optionally type your target keyword (single word or phrase) so the tracker shows its frequency and density against the ideal range, set a minimum word length, and toggle Ignore common stop words to filter out filler.
- 3 Click Analyze Keywords. The tool reports total words, unique words, sentences, average word length, and reading time, then lists your most frequent terms.
- 4 Switch between the Single Words / 2-Word / 3-Word tabs to study phrases, choose how many rows to show (Top 10–100), and sort the table by count or density.
- 5 Read the Recommendations panel. It warns you if a keyword is too sparse, sits in the optimal range, or crosses into keyword stuffing, so you can adjust the wording before publishing.
Why use this tool?
Search engines reward content that uses keywords naturally and penalize pages that repeat the same term too aggressively. Checking keyword density before you publish helps you stay in the safe range, avoid stuffing, and keep your writing readable for real people. Phrase-level (n-gram) analysis goes further by surfacing the 2- and 3-word combinations readers actually search for, while the stop-word filter strips out noise so the terms that define your topic stand out. The target-keyword tracker tells you at a glance whether your main term is below, within, or above the ideal range, and the extra stats — sentences, average word length, and reading time — give a quick readability picture. Because everything happens locally in your browser, your draft stays private and the results are instant even on a slow connection. Whether you are an SEO specialist auditing a page, a blogger optimizing a post, or a copywriter checking a product description, density data turns guesswork into a clear, measurable target.
Examples
Paste a 1,200-word article with the target keyword email marketing. The tracker shows it appears 9 times for a density of 0.75% — comfortably inside the optimal range.
Switch to the 2-Word Phrases tab and discover that content strategy appears far more than expected, revealing a natural phrase to strengthen across headings and body copy.
A short 200-word page repeats cheap shoes 14 times, pushing density above 7%. The tool flags this as stuffing so you can rewrite it before search engines penalize the page.
Enable Ignore common stop words and sort by density. Filler words disappear, exposing the real top terms so you can diversify vocabulary and sharpen the page topic.
Frequently Asked Questions
What is a good keyword density?
For most content a density of 0.5% to 2.5% is ideal. Anything much higher risks looking like keyword stuffing, while a very low density may not signal enough relevance to search engines.
What is n-gram analysis?
An n-gram is a sequence of n words. The Single Words tab counts individual words, while the 2-Word and 3-Word tabs count adjacent phrases. Phrase analysis reveals the multi-word terms people actually search for.
What does the stop-word filter do?
When enabled, it removes very common words such as "the", "and", "of", and "to" before counting. This stops filler from dominating the results so the meaningful terms in your content stand out.
Is my content uploaded to a server?
No. All counting and density calculation happens inside your browser, so your draft is never sent to or stored on a server. The analysis is fully private.
What is keyword stuffing?
Keyword stuffing is overusing a keyword in an unnatural way to manipulate rankings. Search engines detect it and can penalize the page, which is why the tool warns you when density gets too high.
Should I write to hit an exact percentage?
No. Use density as a guide, not a rule. Focus on natural, helpful writing and use synonyms and variations of your keyword rather than forcing a specific number.
