Keyword Density Checker
Count how often a keyword appears in your content and check the density percentage.
About the Keyword Density Checker
Keyword density is the share of your content occupied by a target keyword — occurrences multiplied by the words in the phrase, divided by total words. It stopped being a ranking lever years ago (modern search engines read topics and synonyms, not raw counts), but it remains a useful sanity check in both directions: a density near zero suggests the page never clearly commits to its topic, while a high one reads as spam to humans and can trip over-optimization filters.
This checker counts whole-word, case-insensitive matches — searching for 'car' won't inflate the count with 'carpet' or 'scared' — and handles multi-word phrases with any spacing between the words. You get the total word count, the number of occurrences, the density to two decimals, and a plain verdict: under 0.5% reads as low, 0.5–2.5% is the comfortable range most SEO practitioners aim for, and beyond 2.5% you're flirting with keyword stuffing. Everything recalculates live as you edit, so you can tune a draft in place.
Use the number as a smoke alarm, not a target. If density is low, the fix is rarely to sprinkle the exact phrase mechanically — it's to check that the keyword appears where it structurally matters: the title, the first paragraph, at least one heading, and the meta description. If density is high, replace repetitions with natural variants and pronouns; if a sentence sounds robotic when read aloud, a search engine's spam classifier tends to agree. Write for the reader first, then verify the numbers here.
Frequently asked questions
- What is a good keyword density?
- Roughly 0.5–2.5% for a primary keyword. There's no magic number that improves ranking — the range simply marks where content usually reads naturally while staying clearly on topic.
- Does keyword density affect Google rankings directly?
- Not as a positive factor — Google evaluates topical relevance far more subtly. But extreme repetition can trigger over-optimization spam signals, so the check protects the downside rather than boosting the upside.
- How are multi-word phrases counted?
- The phrase must appear with its words in order (any whitespace between them), matched case-insensitively as whole words. Density then counts every word of each occurrence, so a 2-word phrase appearing 5 times in 500 words is 2%.
- Should I check variations separately?
- Yes — run singular and plural forms and close synonyms as separate checks. Modern SEO rewards covering the topic's vocabulary, not repeating one exact string.
