Keyword Frequency Counter

Why use a keyword frequency counter?

Whether you're editing an article, checking keyword density for SEO, or analyzing writing patterns, seeing which words repeat most often gives useful insight that's hard to spot just by reading. As a keyword frequency counter free of any sign-up, this tool counts every word instantly and ranks them by frequency.

Everything runs locally in your browser, your text is never uploaded or stored, so this keyword frequency counter online free tool has no hidden limits or paid tiers.

What is keyword density?

Keyword density means how often a keyword appears in a piece of text compared to the total word count, expressed as a percentage. If a keyword appears 6 times in a 300-word article, its keyword density is 2%. SEO professionals check keyword density to make sure a page uses its target keyword naturally, enough for search engines to understand the topic, but not so much that it reads as keyword stuffing.

How to calculate keyword density

The keyword density formula is simple:

Keyword Density = (Keyword Count ÷ Total Words) × 100

This tool does the calculation for you automatically, paste your text and every word and phrase is shown with its count and density percentage. Switch between 1-word, 2-word, and 3-word tabs to check density for single keywords and longer key phrases like "best running shoes".

What is the ideal keyword density for SEO?

There is no official number from Google, but most SEO professionals aim for a keyword density of roughly 1-2% for the main keyword. Below that, the topic may not come through clearly; well above it, the text starts to feel repetitive and may be treated as over-optimized. Rather than chasing an exact percentage, use this checker to spot extremes, a keyword at 5%+ density almost always reads unnaturally, while related terms and synonyms spread the topic signal more safely.

Word frequency analysis for writers and researchers

Word frequency analysis is useful well beyond SEO. Writers and editors use it to catch overused words and repetitive phrasing before publishing. Students and researchers use it to study vocabulary patterns in essays, speeches, and interview transcripts. Language learners use it to find the most common words in a text they are studying. As a word frequency analyzer, it works on any pasted text, an article, a chapter, a transcript, and the ranked list reveals patterns that are nearly impossible to spot by reading alone.

How to use it

1. Paste or type your text into the box.
2. Toggle "Ignore common words" to filter out words like "the" and "and".
3. See the top 25 words ranked by frequency, updating instantly.
