Word Density Counter

Word density (often called keyword density) measures how frequently a specific word or phrase appears in your content relative to the total word count — expressed as a percentage. For SEO, it helps search engines understand what your page is about. A balanced keyword density (typically 1–3%) signals relevance without triggering spam filters. Too low and search engines may not identify your topic clearly; too high and you risk keyword stuffing penalties from Google.

There's no single "perfect" keyword density number. However, most SEO experts recommend keeping your primary keyword density between 1% and 3%. For a 1,000-word article, that means your target keyword appears roughly 10–30 times. More importantly, focus on natural writing and semantic relevance. Google's algorithms (like BERT and helpful content updates) prioritize context, user intent, and topical depth over mechanical keyword repetition. Use related terms, synonyms, and LSI keywords to build comprehensive topical authority.

Stop words are common function words like "the," "a," "is," "and," "of," "in," etc. They are necessary for grammar but carry little semantic meaning for content analysis. Excluding stop words (enabled by default in this tool) gives you a much clearer picture of your content's topical keywords. When analyzing keyword density for SEO, filtering out stop words helps you focus on meaningful terms that actually impact search relevance. This tool uses a comprehensive list of 100+ English stop words.

Keyword stuffing — overloading a page with keywords in an unnatural way — is a well-known Google spam policy violation. Consequences include: manual actions that remove your page from search results, algorithmic downgrading (Panda update specifically targeted thin/stuffed content), poor user experience leading to higher bounce rates, and loss of credibility. Modern SEO prioritizes reader-first content. If your keyword density exceeds 5%, carefully review your writing — it likely sounds unnatural to human readers.

Word density is a simple ratio: (word occurrences / total words) × 100%. It only considers your own content. TF-IDF (Term Frequency – Inverse Document Frequency) is more sophisticated — it weighs a term's frequency in your document against how common it is across many documents. A word that appears frequently in your content but rarely elsewhere gets a high TF-IDF score, signaling strong topical relevance. Many advanced SEO tools use TF-IDF to identify content gaps and semantic keywords you should include to match top-ranking pages.

1. Paste your draft and analyze with stop words excluded.
2. Check if your target keyword falls within the 1–3% ideal range.
3. Review the top 25 words — do they reflect your intended topic?
4. Look for unexpected high-frequency words that might dilute topical focus.
5. Identify missing semantic keywords that competitors use.
6. Adjust your content naturally — don't force keywords where they don't belong.
7. Re-analyze after editing to verify improvements.
