Keyword Density Checker

What is Keyword Density?

Keyword density is the percentage of times a keyword or phrase appears in your content relative to the total number of words. It is a classic on-page SEO metric used to gauge whether content is appropriately focused on a topic without overusing a term to the point of looking spammy.

Our Keyword Density Checker counts every word and multi-word phrase in your text, ranks them by frequency, and shows the density percentage for each. You can analyze single words, two-word phrases, or three-word phrases, and optionally ignore common filler words.

How to Use the Checker

• Paste your article, blog post, or page copy into the text area
• Choose whether to analyze 1-word, 2-word, or 3-word phrases
• Toggle "ignore common words" to filter out the, and, of, and similar
• Review the ranked list of top keywords with counts and density bars
• Use the totals to understand the overall size and focus of your content

What is a Good Keyword Density?

There is no magic number, but a commonly cited healthy range for a primary keyword is roughly 1–2% of the total word count. Densities far above that can signal keyword stuffing, which modern search engines penalize. Densities near zero may mean your content is not clearly focused on the topic you want to rank for.

Rather than chasing a precise percentage, use density as a sanity check: confirm your target keyword and related phrases appear naturally and prominently, while the overall writing still reads well for humans.

Two and Three-Word Phrases Matter

Searchers increasingly use longer, more specific queries, so optimizing for multi-word phrases (long-tail keywords) is often more effective than chasing single high-competition words. Analyzing two and three-word phrases reveals whether your content naturally includes the longer queries your audience actually searches for.
