What is Word Frequency Analysis?
Word frequency analysis counts the number of times each unique word appears in a text and typically presents the results as a ranked list — most frequent words first. This gives you an instant view of which words dominate your content.
Use Cases
- SEO keyword density: Check how many times your target keyword appears relative to total word count. Ideal density is 1–3%.
- Over-optimization detection: Keyword stuffing (density over 5–7%) can lead to Google penalties. Use frequency analysis to stay balanced.
- Content analysis: Understand what themes dominate a large document or article.
- Academic research: Analyze frequency of terms in research papers, speeches, or literature.
- Writing improvement: Find overused words in your own writing and replace them with alternatives.
How to Analyze Word Frequency
What are Stop Words?
Stop words are extremely common, low-value words that appear in almost every piece of text: "the", "a", "an", "is", "and", "or", "of", "in", "to", "for", etc. Filtering them out with the "Hide stop words" option reveals the genuinely meaningful keywords in your content.
FAQ
What is a good keyword density?
Most SEO experts recommend 1–3% for the main keyword. Secondary keywords should be under 1% each. Avoid going over 5% for any single term — it looks spammy to search engines and readers alike.
Can I use this for multiple languages?
The word tokenizer uses space and punctuation as word boundaries, so it works with any Latin-script language. Stop-word filtering only works for English stop words by default.
