Paste your content to analyze keyword frequency, density, and distribution. Identify over-optimization and find content gaps instantly.
Keyword density is the percentage of times a specific keyword appears in your content relative to the total word count. For example, if your article is 1,000 words and your target keyword appears 10 times, its density is 1%.
While keyword density was a major ranking factor in early SEO, modern Google uses far more sophisticated signals. Today, keyword density matters primarily as a sanity check — helping you ensure you've included your target keyword enough to establish topical relevance, without stuffing it to the point of triggering spam filters.
After analysing your content here, use our AI Meta Tag Generator to ensure your target keyword also appears correctly in your title tag and meta description.
| Density Range | Status | What It Means |
|---|---|---|
| Under 0.5% | Too Low | Keyword may not appear enough to establish topical relevance |
| 0.5% – 2% | ✓ Ideal | Natural usage that signals relevance without over-optimisation |
| 2% – 3% | Borderline | Acceptable if it reads naturally; review surrounding context |
| Over 3% | ⚠ Over-optimised | Risk of keyword stuffing penalty — reduce usage |
These thresholds are a guide, not a rule. Context matters — a highly technical tutorial may naturally repeat a term more than a general overview article. Always prioritise readability over hitting a specific number.
Content quality is one part of SEO. Check your site's technical health, Core Web Vitals, and more.
🚀 Run Free SEO Audit →Keyword density matters less than it did in 2010, but it's still a useful diagnostic tool. It helps you confirm your keyword appears enough to establish relevance, and flags over-optimisation that could trigger spam filters. Aim for 0.5–2% as a general guideline.
Keyword stuffing is the practice of unnaturally forcing a keyword into content at excessive frequency in an attempt to manipulate rankings. Google's Penguin algorithm specifically targets keyword stuffing and can penalise or de-rank affected pages.
LSI (Latent Semantic Indexing) keywords are conceptually related terms that naturally appear around a topic. For "digital marketing", LSI keywords include "social media", "content strategy", "email campaigns". Including them signals topical depth to Google.
Analyse your top-ranking competitors. Take the top 3–5 pages ranking for your target keyword, paste them into this tool, and compare their keyword density. Match their range rather than guessing a universal ideal.
