Keyword Density Checker
Paste your content to see 1‑word, 2‑word and 3‑word phrase densities. Spots potential keyword stuffing automatically.
How to Use Keyword Density Checker
- Paste your text. Copy your article, blog post or product description and paste it into the input area. You can also fetch content from a live URL if the tool supports it.
- Click Analyze. The tool counts every word and calculates the density of single words (unigrams), two‑word phrases (bigrams) and three‑word phrases (trigrams).
- Review the density table. Your target keyword and its close variants are highlighted with their percentage frequency. There is no fixed ideal density, but the table helps you spot overuse.
- Check the n‑gram warnings. The trigram view shows if you have repeated the same three‑word phrase too often — a sign of unnatural writing that search engines may penalise.
Benefits of Keyword Density Checker
- Goes beyond single‑word counting by analysing bigrams and trigrams, catching repetitive phrase patterns that simple density tools miss.
- No arbitrary density target is enforced — the tool presents the data and lets you decide, aligning with modern SEO practices that prioritise natural writing over mechanical keyword placement.
- Helps avoid keyword stuffing penalties by showing exactly which phrases appear too frequently, so you can vary your language.
- Fully private — your text is analysed in your browser and never uploaded to any server.
Frequently Asked Questions
What is a good keyword density for SEO in 2025?
There is no single "good" percentage. Focus on using your primary keyword in the title, one heading, the first paragraph, and naturally throughout. The checker helps you ensure variety, not hit an arbitrary number.
Does Google penalise high keyword density?
Google’s algorithms can detect unnatural repetition and may demote content that reads as spammy. The checker’s trigram view helps you identify phrases that cross the line from optimisation to stuffing.
Can I check keyword density for a live page?
If the tool supports URL fetching, you can enter a live URL and it will extract and analyse the text content. Otherwise, paste the text directly from the page.
Is Keyword Density Checker free and private?
Yes — it is 100% free, needs no sign‑up, and everything runs in your browser; your data never leaves your device.
