Analyze keyword density with n-gram analysis. Check 1-word, 2-word, and 3-word phrase frequency in your content. Private — files stay in your browser.
A keyword density checker analyzes text content to determine how frequently specific words and phrases appear. It calculates the percentage each term represents of the total word count, helping content creators optimize their writing for search engines without over-optimizing.
Search engines use word frequency as one of many signals to understand what a page is about. If your target keyword appears too rarely, search engines may not associate your page with that topic. If it appears too often, it may be flagged as keyword stuffing — a practice that can lead to ranking penalties.
Look at your target keyword's density. If it's below 1%, consider adding it more naturally throughout your content. If it's above 3–4%, you may be over-using it. Check 2-word and 3-word phrases to find natural variations of your keyword that you can use to diversify your content.
Modern SEO is about topic relevance, not keyword counting. Use keyword density as a sanity check, not a target. Focus on covering a topic thoroughly, using related terms and synonyms naturally, and providing genuine value to readers. Search engines understand context and synonyms far better than they did a decade ago.
Your text is analyzed entirely in your browser. Nothing is uploaded or stored.
Check your content's readability with the Readability Score Checker. Count words with the Word Counter.
Keyword density is the percentage of times a word or phrase appears relative to the total word count. It helps identify how prominently a keyword features in your content.
There's no magic number. Most SEO experts recommend 1–3% for primary keywords. Focus on natural writing rather than hitting a specific percentage.
N-grams are sequences of N consecutive words. 1-grams are single words, 2-grams are two-word phrases, and 3-grams are three-word phrases.
If any single keyword density exceeds 3–4%, it may indicate keyword stuffing, which can hurt rather than help SEO.
