Practical tips for English text

• For English SEO, keep keyword density between 1–2% in Keyword Density Analyzer. English words are often longer than English equivalents, so the same idea uses more characters but may need fewer repetitions to reach 2%.
• Running keyword analysis on English content in Keyword Density Analyzer: paste one language at a time. Mixed-language drafts split keyword frequency across both vocabularies and produce misleading density numbers.
• Keyword Density Analyzer shows raw frequency and density. For English content, pair the density number with search intent — a technically correct density still needs the keyword in the right structural position.
• If you write in English regularly, bookmark this page — the workflow on mobile and desktop is identical and nothing requires an account.

Why Keyword Density Analyzer for English?

Frequently asked questions — Keyword Density Analyzer for English

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.
