Instantly check keyword density in any text or URL. Paste your content or enter a page address — our free keyword density tool counts every word and phrase, calculates exact percentages, detects keyword stuffing, and shows your top 1-word, 2-word, and 3-word phrases ranked by frequency.
Add your target keywords to check density, prominence, and placement. Leave blank to see the top words and phrases in your content.
Paste your content on the left (or fetch from a URL), optionally add your target keywords, then click Analyze Keyword Density.
Keyword density is the percentage of times a target keyword appears in a piece of content relative to the total word count. For example, if your article contains 1,000 words and your keyword appears 10 times, the keyword density is 1%. Use the keyword density calculator above to check this instantly for any text or URL.
While Google no longer uses keyword density as a direct ranking signal, it remains important as a proxy for topical relevance. Content that never mentions the target keyword naturally will struggle to rank for it. Equally, content with extremely high density signals keyword stuffing — a practice Google actively penalises.
Our free keyword density tool goes beyond a simple percentage — it checks keyword prominence (how early the keyword appears), phrase frequency across 1, 2, and 3-word combinations, and flags any density above 3% as a stuffing risk.
Keyword Density Formula
Our keyword density calculator runs this calculation automatically for every keyword and phrase in your content.
Professional SEO review tools — like Semrush, Ahrefs, and SurferSEO — all include a keyword density checker in their content analysis suite because density is a foundational metric for understanding how well a piece of content is optimised for its target terms. Our free tool gives you the same data without the subscription fee.
Unlike a simple percentage counter, our keyword density analyzer checks:
Pair with our Full SEO Analyzer
Keyword density is just one signal. Run a full SEO audit to check title tags, meta descriptions, Core Web Vitals, schema, and 20+ other ranking factors.
Our built-in keyword stuffing checker flags any keyword or phrase with density above 3%. Keyword stuffing — repeating a keyword excessively to try to rank higher — is a direct violation of Google's spam policies and can result in a manual penalty or algorithmic demotion.
Repeating a keyword unnaturally (e.g. "best keyword density checker free keyword density checker tool check keyword density") to manipulate search rankings. Google detects this through Panda and spam algorithms.
Most SEO experts consider density above 2–3% to be potentially over-optimised. Our keyword stuffing checker flags any keyword above 3% as a risk and recommends reducing it.
Replace some exact keyword instances with synonyms, related terms, and natural variations. Use LSI keywords (related terms the tool identifies in the phrase tables) to improve topical depth without repeating exact phrases.
Use our free online keyword density checker to analyse any content in four steps — no account, no limit.
Paste your article content into the text box, or enter the URL of any live page to automatically extract its text. Our word density checker strips navigation, ads, and sidebar content — leaving only the main article.
Add up to 3 target keywords. These are the terms you're trying to rank for. Our keyword density analyzer checks each one individually for density, prominence, and stuffing risk.
Toggle stop-word filtering to exclude common words like "the", "and", "is" from the frequency tables. Enable keyword highlighting to see exactly where each keyword appears in the text.
Get your full keyword density report instantly — including density %, prominence score, phrase frequency tables, readability score, and a highlighted text preview with your keywords marked.
Aim for Natural Density
Write for readers, not search engines. Naturally written content about a topic will include the keyword at an appropriate density (0.5–2%) without conscious effort. Use the tool to verify after writing — not before.
Prioritise Keyword Prominence
Place your target keyword in the first 100 words of the article. Google gives extra weight to terms appearing early in the content. Our analyzer flags "Low" prominence if the keyword doesn't appear in the first 10% of the text.
Use Phrase Variations
The 2-word and 3-word phrase tables show what Google's NLP systems will associate with your content. Include variations from those tables to build topical authority without repeating the exact keyword phrase.
Balance Readability
High readability scores correlate with lower bounce rates — and lower bounce rates signal quality content to Google. Our readability checker estimates your Flesch score so you can balance keyword density with natural, readable prose.
Never Keyword Stuff
Density above 3% almost always sounds unnatural to readers and triggers Google's spam filters. If the stuffing detector fires, replace exact matches with synonyms or restructure sentences to reference the topic differently.
Check Competitor Content
Fetch a top-ranking competitor's URL into this tool to see their keyword density and phrase patterns. This gives you a benchmark for how often the keyword naturally appears in content that Google already ranks at position 1.
