Keyword density checker free online: analyze frequency and SEO balance
Keyword density analysis helps you verify that your target keywords appear often enough to establish topical relevance without crossing into keyword stuffing territory. This free online keyword density checker goes beyond simple word counting: it analyzes 1-word, 2-word, and 3-word phrase frequencies, filters common stop words, and shows a bar chart visualization of the top keywords relative to each other.
The Spotlight Keyword feature lets you enter any specific phrase: including multi-word long-tail terms: and instantly see its count, percentage of total words, a green/yellow/red SEO indicator, and the first sentences where it appears. This is particularly useful for checking whether your primary and secondary keywords are evenly distributed throughout your content or concentrated in just one section.

Keyword density between 1–3% is the sweet spot. Under 0.5% may signal thin coverage; over 5% risks keyword stuffing.

Frequently Asked Questions
- What is keyword density and why does it matter for SEO?
- Keyword density is the percentage of times a keyword appears relative to the total word count. While not a direct ranking factor, it helps ensure your content is topically relevant without over-optimizing.
- What is the ideal keyword density for SEO?
- A density of 1–3% for your primary keyword is generally considered natural. Below 0.5% may mean the topic is underemphasized; above 5% can look like keyword stuffing to search engines.
- Does the checker remove stop words for 1-word analysis?
- Yes. Common English stop words (a, the, is, are, etc.) are filtered out from the 1-word frequency table so you see only meaningful keywords.
- What are 2-word and 3-word phrases in keyword density?
- 2-word phrases (bigrams) and 3-word phrases (trigrams) help identify long-tail keywords and semantic phrases that indicate topical depth beyond single-word analysis.
- What is lexical density?
- Lexical density is the ratio of unique words to total words. Higher lexical density (60%+) suggests more varied, information-rich writing. Lower density indicates repetitive text.
- How does the Spotlight Keyword feature work?
- Enter any keyword or multi-word phrase in the Spotlight field to see its exact occurrence count, density percentage, and the first sentences in which it appears.
- Can I check density for competitor content?
- Yes. Paste any text: your own content or copied competitor text: and the tool analyzes it the same way.
- Is keyword density still relevant for modern SEO?
- While Google does not use keyword density as a direct signal, ensuring your target keyword and semantic variations appear naturally throughout the content remains a good practice for topical relevance.
