Uses for Word Frequency Analysis
SEO Keyword Density
Paste a blog post or landing page and check which keywords appear most often. High-frequency content keywords signal relevance to search engines — but avoid over-optimising (keyword stuffing).
Spot Overused Words
Writers often repeat favourite words without noticing. Run your draft through the analyzer, sort by frequency, and replace the top few repeated words with synonyms for more varied prose.
Topic Modelling
The most frequent non-stop words in a document are often its main topics. Use frequency analysis to quickly summarise what a long document is about without reading it fully.
Compare Two Texts
Run frequency analysis on two different versions of a document to see which terms increased or decreased. Useful for content audits and tracking how messaging evolves over time.
Vocabulary Richness
A text where the top word appears 50+ times is less lexically varied than one where the top word appears 10 times. Use frequency analysis to assess and improve vocabulary diversity.
Prepare Stopword Lists

Frequently Asked Questions
How does the word frequency analyzer work?
The tool splits your text into individual words (matching sequences of letters and apostrophes), converts them to lowercase, and counts how many times each unique word appears. Results are sorted from most to least frequent.
What does "Ignore common words" do?
"Ignore common words" removes stopwords — very common words like "the", "and", "is", "in", "a", etc. — that appear in almost every piece of text and rarely indicate the topic. Filtering them out surfaces the more meaningful, content-specific words.
Is the analysis case-sensitive?
No. All words are converted to lowercase before counting, so "Apple", "apple", and "APPLE" all count as the same word.
Does it count punctuation?
No. Punctuation attached to words (e.g. the full stop in "end." or the comma in "word,") is stripped before counting. Only letters and apostrophes are included in a word.
What can I use word frequency analysis for?
Common uses include: SEO keyword analysis (checking which keywords dominate your content), content editing (spotting overused words), text analysis and research, sentiment analysis preparation, and proofreading for unintended repetition.
Is there a text length limit?
No hard limit. The analysis runs entirely in your browser. Texts up to several hundred thousand words process in under a second on modern hardware. Very long texts may take a moment to display the table.
