What is word frequency analysis?

Word frequency analysis counts how many times each word appears in a text. It is used in SEO to check keyword density, in academic writing to detect overused words, in content creation to ensure topic consistency, and in linguistics research to understand language patterns.

🔍 SEO keyword density

Optimal keyword density for SEO is 1–2% of total word count. Too low = Google may not see the page as relevant. Too high (keyword stuffing) = Google penalty. Use this tool to hit the sweet spot.

📝 Academic writing

Professors and tutors notice word repetition. Use frequency analysis to find overused words in your essay and replace them with synonyms for more varied, professional writing.

🚫 Stop words

Stop words are common words like "the", "a", "is", "and" that carry no meaning. This tool ignores them by default so you see your meaningful keywords. Toggle to include them for full analysis.

💡 2-word phrases

Enable "2-word phrases" to find common bigrams in your text — pairs of words that appear together frequently. Useful for finding natural keyword phrases for SEO and checking for unintentional repetition.

Frequently asked questions

What is keyword density and why does it matter?

Keyword density = (keyword count / total words) × 100%. For SEO, 1–2% is considered optimal for your target keyword. Lower means the page may not rank for that term. Higher (3%+) is considered keyword stuffing and can hurt rankings. Use this tool to measure and adjust your content's keyword density.

What are stop words?

Stop words are extremely common words that are usually filtered out in text analysis because they don't carry meaningful information: the, a, an, is, are, was, were, be, been, have, has, had, do, does, did, will, would, shall, should, may, might, must, can, could, of, in, on, at, to, for, with, by, from, and, but, or, so, yet, nor.

How do I use this for SEO content writing?

1. Write your article targeting a specific keyword. 2. Paste the article here. 3. Check the density of your target keyword — aim for 1–2%. 4. Also check what other words dominate — they should all be topically related to your main keyword. 5. Use the 2-word phrases option to check for natural keyword phrase usage.
