Keyword density refers to the percentage of times a keyword appears in your content relative to the total word count. While keyword stuffing was a tactic in early SEO, modern search engines penalise it. The goal is natural, readable content where important keywords appear at a reasonable density — typically 1–3% for primary keywords.
What Keyword Density Tells You
- Primary keyword density: Is your main keyword mentioned enough (not too little, not too much)?
- Keyword stuffing detection: Any word above 5–6% density may flag over-optimisation
- Secondary keyword distribution: Are related keywords well distributed throughout the content?
- Common filler words: Identify stop words that inflate word count without adding value
Ideal Keyword Density Guidelines
- Primary keyword: 1–3% of total word count
- Secondary keywords: 0.5–1.5% each
- Avoid any keyword above 5% — risk of over-optimisation penalty
- Focus on natural language — write for readers, not robots
How to Check Keyword Density — Step by Step
- Paste your content: Copy the text you want to analyse into the input box.
- Analyse: Click "Analyse" — keyword frequency and density percentages appear.
- Review the results: See each word's count and percentage of total word count.
- Identify issues: Look for keywords above 5% (too many) or below 0.5% (too few).
- Refine your content: Adjust your writing based on the analysis and re-check.
