- What is word frequency analysis used for?
- Word frequency analysis reveals which words dominate a text. Uses include: SEO keyword density checking (is your target keyword appearing enough?), identifying overused words in writing, analysing competitor content, corpus linguistics research, and detecting authorship patterns.
- What are stop words and should I exclude them?
- Stop words are extremely common words (the, a, is, in, of, and) that appear in virtually every text and carry little meaning for analysis. Enable "Exclude stop words" when analysing content words (nouns, verbs, adjectives) to surface meaningful keywords. Keep stop words when analysing writing style or readability.
- What is keyword density and what is a good target?
- Keyword density is the percentage of times a keyword appears relative to total word count. For SEO, 0.5–2.5% is generally considered natural. Above 3% may be flagged as keyword stuffing by search engines. Use the frequency percentage column to monitor density for your target keywords.
- How is the percentage calculated?
- The percentage shown is the word count divided by the total word count in the text, multiplied by 100. For example, if "calculator" appears 15 times in a 500-word article, its density is 15/500 × 100 = 3%. The total includes all words, regardless of whether stop words are filtered in the display.
- Why does my exported CSV have different counts than displayed?
- The CSV exports the current filtered view (including any minimum count filter and stop word exclusion settings). If you want to export all words, set the minimum count to 1 and disable stop word exclusion before exporting.
- Does the tool handle non-English text?
- The counter tokenises on whitespace and extracts Latin letter sequences (a–z). It handles English, Spanish, French, German, and other Latin-alphabet languages. Non-Latin scripts (Chinese, Arabic, Japanese) are not split into individual words by the current tokeniser.
- What is the maximum text size I can analyse?
- The tool runs entirely in your browser with no size limit enforced. Very large texts (100,000+ words) may take a second to process due to the frequency counting algorithm. For very large texts, consider sampling a representative section.
