How to Use the Keyword Density Checker

Paste your text and type the keyword to check. Leave the keyword blank to auto-pick the most frequent word. The Top 10 words list shows the overall vocabulary balance.

Use it as a quick editorial check for SEO drafts, landing pages, product copy and article outlines. The goal is not to hit a magic percentage; it is to spot accidental repetition, missing focus terms and wording that feels unnatural.

Examples

  • English paragraph (18 words), keyword "the" → 4 occurrences / 22.22% density (a sign of stuffing)
  • A draft with "keyword" three times → 3 occurrences / density is that word's share of total words
  • Leave the keyword blank → the most frequent word is auto-selected for the count and density
  • Top 10 words → listed in descending order, e.g. "the 4 / dog 2 / fox 2 …"
  • Case → "The" and "the" are merged into one word (case-insensitive)

Reading the Results

  • Occurrences shows how many times the target keyword appears.
  • Density shows that count as a share of total words.
  • Top 10 words helps reveal overused filler words or repeated product terms.

FAQ

Is my data sent to a server?
No. Everything runs in your browser; nothing is transmitted or stored externally.
Density formula?
(keyword occurrences ÷ total words) × 100 (%). Both the count and the density use total words as the denominator.
What counts as one word?
A run of alphanumerics, or a run of hiragana, katakana or kanji, counts as one word. Case is ignored; punctuation and spaces act as separators.
What shows when no keyword is entered?
The most frequent word is picked automatically, and its count and density are shown. The top words are listed under Top 10 words so you can spot imbalance at a glance.
