How to Use This Keyword Density Checker Step by Step
Getting accurate output for any word frequency counter or SEO content checker task takes three straightforward steps in the tool above:
- Step 1: First, paste your article copy or switch tabs to fetch text from a live public webpage URL.
- Step 2: Next, enter an optional target focus phrase and keep Stop-Word Filtering enabled to hide filler words.
- Step 3: Finally, switch between 1-Word, 2-Word, and 3-Word tabs to spot optimal terms or >3% stuffing alerts.

Unigram, Bigram & Trigram Term Frequency (TF) Math
Single-word density divides term occurrences by total body words: Density % = (Term Count ÷ Total Words) × 100. For a multi-word phrase of length k, word-share coverage equals (Phrase Matches × k ÷ Total Words) × 100. Meanwhile, sliding-window phrase ratio divides matches by (Total Words − n + 1) across 2-word and 3-word n-grams.
Because our Keyword Density Checker applies these rules automatically, you avoid manual rounding mistakes. Furthermore, users looking for article analyzer or SEO optimization tool workflows can test multiple scenarios side by side before finalizing their work.

Important Scope, Privacy & Accuracy Notes
Google Search ranks content using semantic entities and helpfulness rather than fixed keyword quotas. Forcing an exact phrase above 3% degrades prose flow and triggers spam policies. Use this breakdown to spot accidental repetition and diversify your vocabulary naturally.
