Keyword Density Checker
Quick answer
Keyword density is how often a target word or phrase appears compared to the total word count in a piece of text—often shown as a percentage. ConvertPal’s checker counts occurrences, estimates density, surfaces repeated unigrams/bigrams/trigrams, and can ignore common stop words, all in your browser.
Editors and SEOs use keyword density as a sanity check—not a magic ranking dial. Paste a draft, optionally set a target phrase, and review frequency, estimated density, and the most repeated short phrases (unigrams, bigrams, trigrams). Toggle stop-word filtering to focus on meaningful terms, highlight matches in context, then copy or export a plain-text report for briefs or clients. Developers and content ops teams can also scan pasted exports before pushing copy into CMS or localization workflows.

Quick FAQ
What is keyword density?
Keyword density measures how often a word or phrase appears relative to the total word count, often expressed as a percentage. It is useful for spotting repetition or imbalance, not as a single ranking guarantee.
What is a good keyword density percentage?
There is no fixed ideal number that applies to every page. Focus on natural language, clear intent, and helpful detail; use density as a warning light for stuffing rather than a target to chase.
Can keyword stuffing hurt SEO?
Yes. Repeating the same phrase unnaturally can annoy readers and may align with spam signals. Modern SEO rewards relevance, experience, and clarity more than raw repetition.
Key benefits
- Target phrase stats plus ranked unigram, bigram, and trigram views.
- Stop-word toggle and in-context highlighting for quick reviews.
- Copy/export reports without sending your draft to a server.
What this tool does
The tool tokenizes your paste into words, normalizes punctuation on the edges of tokens, and computes total word count for the density denominator. Related utilities on ConvertPal include Blog Title Generator, Meta Title & Description Generator, and Slug Generator.
When you enter a target keyword or phrase, it counts non-overlapping whole-word sequence matches and reports how many word positions they consume relative to all words.
Unigram, bigram, and trigram tables rank repeated sequences; optional stop-word filtering removes high-frequency function words from the unigram view so content words stand out.
How to use it
- Paste your article, email, or landing copy into the editor.
- Optionally type a target keyword or phrase to see frequency, density, and highlights.
- Toggle stop words on or off for the unigram table.
- Review bigrams and trigrams for accidental repetition patterns.
- Copy the text report or export a .txt file for sharing.
What is keyword density?
Keyword density compares how many times a chosen word or phrase appears to the total number of words in the text. It is usually expressed as a percentage and was historically used in early SEO discussions, though modern search systems rely on broader relevance and quality signals.
Today, density is best treated as a writing-quality and consistency check: it helps you notice stuffing, awkward repetition, or a missing primary term—not as a score to maximize blindly.
What is a good keyword density?
There is no universally “perfect” percentage. Helpful content reads naturally first; extreme repetition can signal spam to both readers and search engines.
Practical guidance: stay aware of how often your main phrase appears, avoid repeating it in every sentence, and use synonyms and related concepts where they genuinely help the reader.
Privacy model
Analysis runs in your browser. ConvertPal does not upload your pasted content to compute counts or n-grams.
Copy and export actions use your device the same way any local page would.
More context
Pair this page with the meta title and description generator when you are aligning on-page language with SERP snippets, and with the slug generator when you move from phrasing to URL structure.
Use the word counter when you need hard limits for titles, intros, or social variants after you finish a density pass.
