How Does It Work?

Analyze word frequency and phrase density in any text. Features single-word, 2-word (bigram), and 3-word (trigram) frequency tables with stop-word exclusions, keyword density percentages, and CSV export.

Mathematical Formula
Keyword Density % = (Occurrences of Word / Total Words in Text) × 100

Tokenizes text, strips grammatical punctuation, filters common stop words, and groups word frequencies into ranked distributions.

Real-World Worked Example

Analyzing an 800-word blog post for SEO keyword optimization.

Calculation Breakdown
  • •Target phrase: "financial planning"
  • •Occurrences: 16 times
  • •Total Words: 800 words
  • •Computed Keyword Density: (16 / 800) × 100 = 2.0%

Takeaway: Maintaining primary keyword density between 1.5% and 2.5% satisfies search engine crawlers without triggering over-optimization penalties.

Word Frequency Counter FAQs

Common questions, calculation formulas, and usage rules.

An N-Gram is a contiguous sequence of N items. In text, a 1-gram is a single word, a 2-gram (bigram) is a 2-word phrase, and a 3-gram (trigram) is a 3-word phrase.

Filtering common words like "the", "and", "is", and "of" reveals meaningful topical keywords rather than grammatical glue.
