What is word frequency analysis used for?

It is used in SEO for keyword density checks, in academic research to study language patterns, in content editing to spot overused words, and in NLP preprocessing tasks such as spam filtering and sentiment analysis.

Does the counter ignore common words?

Enable stop-word filtering to exclude common function words like the, a, an, is, and. This highlights meaningful keywords rather than grammatical filler.

Is the word count case-sensitive?

By default it is case-insensitive, so Apple and apple are counted together. Enable the case-sensitive toggle to distinguish them — useful when analysing code or proper nouns.

How is the frequency percentage calculated?

Each word count is divided by the total word count and multiplied by 100 — it shows the share of the text that word occupies. A word appearing 20 times in a 1,000-word article has a frequency of 2%.

What is a healthy keyword density for SEO?

A density of 1–2% for your primary keyword is generally considered healthy. Above 4–5% risks looking like keyword stuffing, which can harm rankings. Focus on natural writing rather than hitting a specific density target.

Is my text uploaded to a server?

No. All analysis runs locally in your browser using JavaScript. Your text never leaves your device — safe for confidential documents, client copy or proprietary content.

What Is a Word Frequency Counter?

A word frequency counter scans any block of text and tallies how many times each word appears, then ranks the results from most to least frequent. This gives you an instant snapshot of which words dominate your text — useful for writers, editors, SEO professionals and data analysts who need to understand the vocabulary distribution of a document without reading it word by word.

Word Frequency and SEO Keyword Density

Search engines consider how often a target keyword appears relative to all other words on the page — a metric called keyword density. A density of 1–2% is generally healthy. Rising above 4–5% can signal keyword stuffing and may trigger ranking penalties. Paste your page copy here to see the density of any term at a glance, then use the Word Counter to check total length simultaneously.

Analysis Options

Case-sensitive — treats "Apple" and "apple" as different words. Useful for code or proper nouns.
Ignore stop words — filters out common function words like "the", "a", "and", "is" that carry no meaningful signal.
Min length — hides very short words (set to 4+ to focus on substantive vocabulary).

Common Use Cases

Content editing — identify overused words and replace them with synonyms for variety.
SEO audits — verify your target keyword appears at the right density before publishing.
Academic research — study vocabulary patterns, compare documents, or detect authorship.
NLP preprocessing — frequency data feeds bag-of-words models, spam filters, and sentiment analysis engines.
Translation QA — confirm that key terms in the source text appear the expected number of times in the translation.

How Word Frequency Differs from Word Count

Word count tells you the total number of words in a document. Word frequency breaks that count down by individual term, showing you how many times each specific word appears. A 1,000-word article might use the word "strategy" 15 times (1.5% density) and "marketing" 8 times (0.8% density). This frequency breakdown is far more useful than raw word count for writers polishing their prose, for SEO analysis, and for anyone comparing vocabulary across different documents. Use this tool alongside the Word Counter to get both total length and frequency distribution in one workflow.
