About Keyword Density Checker

The Keyword Density Analyzer counts how often individual words and multi-word phrases (N-grams) appear in your text and calculates each keyword's density as a percentage of total word count. Paste your article, blog post, or page copy directly into the tool to identify over-optimized terms that may trigger search engine penalties, spot gaps where target keywords are underrepresented, and balance your content for both readers and search engines.

Features

  • ✓Single keyword (1-gram) frequency and density percentage
  • ✓Bigram (2-gram) and trigram (3-gram) phrase analysis
  • ✓Stop-word filtering to exclude common words like 'the' and 'and'
  • ✓Sortable results table by frequency or density
  • ✓Total word count and unique word count display
  • ✓Adjustable minimum frequency threshold to focus on relevant terms
  • ✓Clean plain-text input — no URL fetching required
  • ✓Instant real-time results as you type or paste

Common Use Cases

  • Auditing blog posts and landing pages for keyword over-optimization
  • Ensuring target keywords appear at a natural density before publishing
  • Comparing keyword distribution across multiple content drafts
  • Identifying filler phrases that dilute topical relevance
  • Preparing on-page SEO recommendations for clients
  • Benchmarking keyword usage against competitor content

Frequently Asked Questions

QWhat is a healthy keyword density?

There is no universally correct number, but most SEO practitioners suggest keeping primary keyword density between 1% and 3%. Above 5% can look unnatural and risk a keyword stuffing penalty.

QDoes the tool support languages other than English?

The word tokenizer works with any whitespace-delimited language. Stop-word filtering is currently tuned for English; results for other languages will still be accurate for raw frequency counts.

QCan I analyze a live webpage instead of pasting text?

The tool works with pasted text. To analyze a live page, copy the visible page content into the input field, or use your browser's reader mode to extract clean text first.

QWhy are common words like 'the' and 'is' excluded from results?

Stop words are filtered out by default because they carry no topical signal and would dominate the results. You can toggle stop-word filtering off to see the raw frequency of every word.
