Keyword Density Checker
Paste any text to see word frequency, keyword density percentages, and phrase counts.
How to Use
- Paste your article or page content into the text area.
- Click Analyze to see the word frequency breakdown.
- Review density percentages — aim for 1–3% for primary keywords.
- Check 2-gram and 3-gram tabs for phrase-level density.
When to Use This
- Reviewing a draft before publishing to see whether one phrase dominates it in a way an editor would call repetitive.
- Extracting the two- and three-word phrases a competitor's page is built around, after pasting the visible text from it.
- Checking that the topic you set out to write about is actually the most frequent term, rather than a synonym you drifted into.
- Settling an argument about whether a page is over-optimized by looking at the counts instead of trading impressions.
Frequently Asked Questions
About This Tool
Keyword density is the share of a document's words taken up by one term, counted as occurrences divided by total words. It belongs to an era when retrieval scored documents largely on term frequency; current systems weigh a term against how common it is across a whole corpus, and increasingly compare meaning rather than strings. What a word count still shows you is repetition, the phrase you leaned on eleven times without noticing.
Paste text and this tool strips HTML tags with a regular expression, lowercases, keeps letters, digits, apostrophes and hyphens, and discards one-character tokens. It then ranks the top 30 single words, two-word phrases and three-word phrases, with a count, a density percentage and a bar for each. An optional filter removes an 85-word English stop list.
Notes & Limits
- HTML is stripped with a regular expression rather than parsed, so text inside script and style blocks survives and is counted as content.
- Tokenizing keeps only ASCII letters and digits, so text in Devanagari, Chinese, Cyrillic or Arabic produces no tokens and no results at all.
- Single-word density is divided by the total token count taken before stop words are removed, so the listed percentages do not sum to 100 with filtering on.
- Only the top 30 rows per tab are listed. The 1 to 3 percent band often quoted as a target is a convention, not a figure any search engine documents.
