What is a Word Frequency Counter?
A word frequency counter is a text-analytics tool that scans your content and counts how often each word and phrase appears. It ranks every term from most to least frequent and shows its keyword density — turning a wall of text into a clear, data-driven picture of what your content is really about.
Beyond single words, this tool performs n-gram analysis on 2- and 3-word phrases, filters out stop words, detects repetition, and reports vocabulary diversity. It’s built for SEO research, content editing and academic analysis alike. To count totals and reading time, pair it with the Word Counter; for exact letters and spaces, use the Character Counter.

Export & act
Sort the table, copy results, or export CSV, TXT and PDF reports to refine your content and keyword strategy.
Word frequency vs keyword density
They sound alike but answer different questions. This tool shows both side by side so you never confuse a raw count with a concentration.
Word Frequency
- A raw count — how many times a term appears (e.g. “SEO ×12”).
- Answers “how often?” and surfaces repetition and crutch words.
- Great for spotting overused words and dominant themes.
Keyword Density
- A percentage — count ÷ total words (12 in 600 words = 2%).
- Answers “how concentrated?” relative to the whole document.
- Great for benchmarking against the 0.5–2.5% SEO comfort zone.

SEO & content use cases
SEO professionals
Audit keyword usage, spot stuffing, and confirm primary terms sit in a healthy 0.5–2.5% density range.
Content writers
Catch overused words and crutch phrases, then vary your vocabulary for tighter, more engaging prose.
Researchers
Run quick term-frequency and n-gram analysis on transcripts, surveys and corpora without writing code.

Content optimization guide
A four-step routine for turning a frequency report into measurably better, search-optimized content.
Establish a baseline
Analyze your current draft to see which terms already dominate before you change anything.
Compare to intent
Match the top terms against the keywords your page should rank for. Gaps reveal what to add.
Balance the density
Lift under-used target keywords and trim anything pushing past ~2.5% to avoid keyword stuffing.
Enrich with phrases
Use the bigram and trigram views to weave in natural supporting phrases and related entities.
Keyword research tips
Lead with one primary term
Pick a single focus keyword per page and make sure it ranks among your top terms — without dominating.
Mine bigrams for intent
Two-word phrases reveal search intent better than single words. Build sections around the strongest ones.
Cover related entities
Topical authority comes from breadth. Check that synonyms and related concepts also appear, not just the exact keyword.
Filter the noise
Always enable stop-word filtering for keyword research so function words don’t hide the terms that matter.
Content writing best practices
Vary your vocabulary
If one word tops the list by a wide margin, swap in synonyms to keep prose fresh and readable.
Write naturally first
Draft for humans, then analyze. Healthy keyword density is a result of good writing, not a target to force.
Kill crutch phrases
Repeated filler like “in order to” or “at the end of the day” shows up fast — cut it for tighter copy.
Front-load key terms
Make sure important keywords appear early — in the title, intro and first subheading — not just in the body.
Common mistakes to avoid
- Chasing an exact keyword-density number instead of writing naturally for the reader.
- Keyword stuffing a single term, which hurts readability and can trigger search penalties.
- Ignoring 2- and 3-word phrases, missing the long-tail intent that drives qualified traffic.
- Leaving stop-word filtering off during research, so “the” and “and” bury your real keywords.
Frequently asked questions
A word frequency counter is a text-analysis tool that scans your content and counts how many times each word or phrase appears. It ranks them from most to least frequent and shows the keyword density of each, helping writers and SEO professionals understand which terms dominate a piece of content. Our tool runs entirely in your browser, updating in real time as you type or paste.
The tool splits your text into individual words (tokens), normalizes them — optionally lowercasing and stripping punctuation — then tallies how often each one occurs. It can also group adjacent words into phrases (n-grams) and remove common stop words like “the” and “and” so the meaningful keywords rise to the top. Each result shows a raw count and a density percentage of the total words.
An n-gram is a sequence of n consecutive words. A 1-gram (unigram) is a single word, a 2-gram (bigram) is a two-word phrase like “content marketing”, and a 3-gram (trigram) is a three-word phrase like “search engine optimization”. Analyzing bigrams and trigrams reveals the multi-word phrases and topics search engines associate with your page, which single words alone can miss.
Stop words are extremely common words — “the”, “a”, “and”, “of”, “to” — that carry little topical meaning. They almost always top a raw frequency list and drown out the keywords that actually matter. Turning on stop-word filtering removes them so the ranking reflects your real subject matter, which is essential for keyword research and SEO analysis.
Word frequency is the raw number of times a term appears (e.g. “SEO” appears 12 times). Keyword density is that count expressed as a percentage of the total word count (12 occurrences in a 600-word article = 2% density). Frequency tells you how often; density tells you how concentrated. Both are shown side by side so you can judge whether a term is under- or over-used.
There is no exact rule, but most SEO professionals aim for a natural density of roughly 0.5%–2.5% for a primary keyword. Going much higher risks keyword stuffing, which hurts readability and can trigger search penalties. Use the density column to confirm your main terms appear often enough to signal relevance without sounding repetitive.
Yes. You can export the full ranked frequency table as a CSV (for spreadsheets and pivot tables), a plain-text TXT file, or a formatted PDF report. You can also copy the results to your clipboard in one click for quick pasting into a document or content brief.
Yes. The tool is 100% free with no sign-up or limits, and all processing happens locally in your browser. Your text is never uploaded or stored on a server, making it safe for confidential drafts, research data and commercial content.
