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. All analysis happens in your browser, so your content stays private.

Keyword Stuffing and Why It Backfires

In the early days of SEO, cramming a target keyword into a page as many times as possible could push it up the rankings. Those days are long gone. Modern search engines use sophisticated language understanding to judge relevance from context and natural writing, not raw repetition, and they actively penalize content that over-uses a phrase to the point of reading unnaturally. Keyword stuffing now hurts rankings rather than helping them, and it drives real readers away with awkward, spammy prose.

This is exactly where a density checker earns its place. Rather than treating density as a target to hit, use it as a guardrail: it shows you when a keyword appears so often that it has crossed from focused into stuffed, letting you dial it back. The goal is content that reads naturally for humans while clearly signalling its topic — and seeing your density laid out is the quickest way to confirm you are on the right side of that line.

What is a good keyword density?

There is no exact figure, but a commonly cited healthy range for a primary keyword is around 1–2% of the total word count. Treat that as a sanity check rather than a target: far above it can look like stuffing, while near zero may mean your content is not clearly focused. Natural, readable writing matters more than any precise percentage.

Why analyze two- and three-word phrases?

People search in phrases, not single words, so long-tail queries of two or three words often convert better and face less competition than broad single keywords. Analyzing multi-word phrases shows whether your content naturally contains the longer, more specific queries your audience actually types — opportunities a single-word view would miss entirely.

Does it count common words like 'the' and 'and'?

You can choose. By default the tool counts every word, but toggling 'ignore common words' filters out high-frequency filler like the, and, of, and similar terms. With them removed, the ranked list surfaces the meaningful keywords that actually describe your topic instead of being dominated by grammar words.

Is my content private?

Completely. All analysis happens locally in your browser, so your text is never uploaded, logged, or stored on a server. It is safe to analyze unpublished drafts, client work, and other confidential content.
