How to Use
- 1Paste or type your text into the input area. You can analyze anything from a short paragraph to an entire article, essay, or book chapter — the tool handles large inputs efficiently.
- 2Review the ranked frequency table that appears automatically. Each row shows a word, its count, and its percentage of total words, giving you an immediate picture of your text's vocabulary distribution.
- 3Use the sorting options to organize results by frequency (highest or lowest first) or alphabetically (A to Z). Switch between views to find specific words quickly or to spot patterns in your vocabulary usage.
- 4Apply the minimum-frequency filter and row limit controls to focus on the data that matters most. For example, show only the top 50 words or exclude words that appear fewer than 3 times to filter out noise from one-off terms.
- 5Toggle the stop-word exclusion to hide common function words like 'the', 'and', 'is', and 'of'. This reveals your content's meaningful keywords and topic-specific vocabulary without clutter from high-frequency grammatical words.
- 6Review the lexical diversity score and summary metrics to assess vocabulary variety. A higher lexical diversity indicates more varied word choices, which is generally desirable for engaging, well-written content.
- 7Use the search filter to find specific words in the results table, then click Copy to export the filtered frequency data to your clipboard for use in spreadsheets, reports, or content briefs.
About Word Frequency Counter
The Word Frequency Counter analyzes any text and displays a ranked table showing each word's count and percentage of total words. Configurable sorting, row limits, search filters, and stop-word exclusion let you drill into the data quickly. Whether you are analyzing a blog post, an academic paper, a novel chapter, or a product description, the tool provides instant, actionable vocabulary insights.
For SEO professionals, keyword density is a critical on-page optimization factor. Search engines use word frequency as one of many signals to determine what a page is about. If your target keyword appears too rarely, the page may not rank for that term. If it appears too often, search engines may flag it as keyword stuffing — a practice that can result in ranking penalties. This tool lets you check density before publishing, ensuring your target terms appear at a natural frequency (typically 1-3% for primary keywords) without over-optimization.
Writers and editors use word frequency analysis to improve the quality and readability of their prose. Overusing certain words — even common ones like 'very', 'really', or 'just' — weakens writing and creates a repetitive reading experience. By analyzing frequency, you can identify these crutch words and replace them with more precise alternatives. The lexical diversity metric provides an overall measure of vocabulary variety: a higher score indicates more diverse word choices, which correlates with more engaging and authoritative content.
Academic researchers and linguists rely on word frequency analysis for corpus linguistics, authorship attribution, and text classification studies. The frequency distribution of words in a text follows Zipf's Law — the most common word appears roughly twice as often as the second most common, three times as often as the third, and so on. Comparing a text's frequency distribution against expected patterns can reveal stylistic characteristics, detect plagiarism, or classify documents by genre or topic.
Content marketers use the tool to reverse-engineer competitor content. Paste a competitor's top-ranking article, analyze word frequency with stop words excluded, and you get a clear picture of the keywords and topic vocabulary they emphasize. This informs your own content strategy, helping you cover the same semantic territory while adding unique depth and perspective that differentiates your content.
The stop-word exclusion feature is particularly valuable because common function words (articles, prepositions, conjunctions) dominate any English text by sheer volume. Words like 'the', 'of', 'and', 'to', and 'in' typically account for 20-30% of all words in a passage. Excluding them reveals the meaningful, content-specific vocabulary that defines what your text is actually about — the nouns, verbs, and adjectives that carry topical weight.

Frequently Asked Questions
Is the analysis case-sensitive?
No. All words are converted to lowercase before counting, so 'The', 'the', and 'THE' are all counted as the same word. This ensures accurate frequency counts regardless of whether words appear at the beginning of sentences or in headings where capitalization differs from body text.
Can I remove common words like 'the' or 'and'?
Yes. Enable the stop-word exclusion toggle to filter out common English function words — articles, prepositions, conjunctions, and pronouns that appear frequently in any text but carry little topical meaning. This lets you focus on the content-specific keywords that actually define what your text is about.
How many words are shown in the results?
You can choose the display cap to show the top 25, 50, 100, or 200 most frequent words. Combined with the minimum-frequency filter, these controls let you zoom in on high-frequency terms or expand the view to include rarer vocabulary — whichever is most useful for your analysis.
Can I sort alphabetically instead of by frequency?
Yes. The results table supports sorting by count (descending or ascending) and alphabetically (A to Z). Alphabetical sorting is useful when you want to quickly locate a specific word, while frequency sorting highlights the most dominant terms in your text.
What is lexical diversity and why does it matter?
Lexical diversity measures the ratio of unique words to total words in your text. A higher score indicates a richer, more varied vocabulary. In content writing, higher lexical diversity generally correlates with more engaging and authoritative prose. In SEO, diverse vocabulary helps pages rank for a broader set of related search queries through semantic relevance.
Can I use this for SEO keyword density analysis?
Absolutely, and it is one of the primary use cases. Paste your article text, exclude stop words, and check that your target keywords appear at a natural density — typically 1-3% for primary keywords and 0.5-1% for secondary terms. The percentage column in the results table gives you exact density figures for every word in your content.
How does word frequency analysis help improve writing quality?
By revealing which words you use most often, frequency analysis exposes repetitive patterns that weaken your prose. If words like 'very', 'really', 'just', or 'things' dominate your results, replacing them with more precise alternatives will strengthen your writing. The analysis also helps ensure that your key topic terms appear consistently throughout the text.
Is my text sent to a server?
No. All analysis runs locally in your browser using JavaScript. Your text never leaves your device, is never uploaded to any server, and is never stored anywhere. This makes the tool completely safe for analyzing confidential documents, proprietary content, client materials, and any text governed by privacy policies or regulatory compliance requirements.
