Why analyse word frequency?

Word frequency tells you what a text is really about. For content creators and SEO professionals, it reveals keyword density — whether your target keyword appears enough (or too much). For writers, it surfaces overused words that make prose feel repetitive. For researchers, it is the first step in text mining and corpus analysis.

How to use this tool

  1. Paste your text into the input area.
  2. Choose case-insensitive (recommended) to merge capitalised variants.
  3. Enable “Exclude stop words” to filter out common function words and see only meaningful terms.
  4. Adjust the top-N selector to show 10, 20, 50, or 100 most frequent words.
  5. Export to CSV for further analysis in Excel or Google Sheets.

Practical use cases

  • SEO keyword density check: Ensure your primary keyword appears at 1–2% density without stuffing.
  • Writing style analysis: Find words you overuse and replace them with synonyms.
  • Academic text analysis: Identify key themes and concepts in a paper or book chapter.
  • Vocabulary building: Analyse a foreign-language text to learn its most common words first.

Frequently asked questions

What is word frequency analysis?
Word frequency analysis counts how often each word appears in a text and ranks them from most to least common. It is used in content SEO (keyword density), linguistics research, plagiarism detection, and understanding writing style.
What are stop words and should I exclude them?
Stop words are common function words like 'the', 'a', 'is', 'and', 'of', 'to' that carry little meaning on their own. In most contexts — SEO analysis, topic modelling, summarisation — you want to exclude them so the meaningful keywords stand out. For linguistic analysis or style profiling, keep them in.
How does case-insensitive mode work?
With case-insensitive mode on (default), 'The' and 'the' and 'THE' are all counted as the same word. With it off, each capitalised form is counted separately, which is useful when capitalisation is meaningful (proper nouns, acronyms).
Can I export the results?
Yes. Click 'Export CSV' to download a CSV file with three columns: word, count, and percentage. The export includes only the words currently shown in the top-N list.
What is a good keyword density for SEO?
Most SEO practitioners aim for 1–2% density for the primary keyword — meaning it appears roughly once every 50–100 words without feeling forced. Keyword stuffing (3%+) can trigger penalties. Use this tool to check density before publishing.
