Glossary
Concepts behind the numbers
The vocabulary writers and editors in Philadelphia run into when they review counts.
- Word countSource ↗
- The total number of word tokens in a piece of text, typically derived by splitting on whitespace and punctuation. Common in publishing, education, and SEO as a length metric.
- Character countSource ↗
- The total number of code points (or graphemes, in Unicode-aware tools) in a text. Platforms like SMS and Twitter enforce limits in characters, not words.
- UnicodeSource ↗
- The international standard that assigns a unique number to every character in every script. Modern text tools use Unicode so counts work consistently across languages and emoji.
- Keyword densitySource ↗
- The percentage of times a target keyword appears relative to the total word count. Once central to SEO, modern guidance treats it as a guardrail (1-2%) rather than a target to maximise.
- Lexical densitySource ↗
- The proportion of content words (nouns, verbs, adjectives, adverbs) relative to the total word count. Higher lexical density indicates information-rich, sometimes harder-to-read text.
- Intl.SegmenterSource ↗
- A JavaScript API that splits text into Unicode graphemes, words, and sentences using the same locale rules browsers use natively. Tools that use it count complex scripts correctly.
How we count, and when this page was checked
Word and character counts on this page use the browser's Unicode-aware Intl.Segmenter API, so figures match the underlying graphemes rather than guessing from byte length. Reading-time estimates default to 238 wpm (Brysbaert, 2019). Last editorial review: 2026-05-23.
