Keyword Density Analyzer
Measure keyword frequency and density in any text — spot keyword stuffing before search engines do.
| Keyword | Count | Density | Status |
|---|
How terms are counted
- N-grams — 1-, 2- and 3-word phrases counted separately; a trigram like content-marketing-strategy reports as one unit.
- Stop-word handling — per-language filterable list so density is not inflated by filler words.
- Placement flags — top terms show hits across title tag, H1-H3, meta description, image alt and opening paragraph.
- Honest baseline — natural prose sits at 0.5–2.5% for a primary term; above 4% flags as stuffing risk rather than encouraging more.
Density plus placement, not just percentages
See which terms dominate, where they appear (title, headings, first 100 words) and whether long-tail variants beat single-word stuffing.
Density, not just counts
Every keyword gets a share-of-text percentage computed against the meaningful tokens — 10 mentions in a 200-word article is clearly different from 10 in 2,000 words.
Keyword-stuffing alerts
Terms repeated past about 3% of the text with at least three mentions get a warning badge — the classic pattern that reads as spam to both users and search engines.
Chinese text included
Chinese has no spaces between words, so the analyzer extracts character bigrams — the standard no-dictionary technique — instead of pretending English word splitting works.
Frequently asked questions
What is a good keyword density?⌄
Search engines publish no official number. In practice, natural copy usually sits between 1% and 3% per keyword; this tool flags terms past about 3% with at least three mentions as worth trimming — a sign to edit, not a guaranteed penalty.
How does it handle Chinese text?⌄
Chinese has no word boundaries, so the tool analyzes adjacent character pairs (bigrams) and filters out pairs containing common function characters like 的了在. That is the standard no-dictionary approach — no segmentation model required.
Is my text uploaded anywhere?⌄
No. Everything runs in your browser; the text never leaves your device. Paste freely, including drafts and client copy.
Is there an ideal keyword density?⌄
No magic number exists — modern ranking cares about topic coverage and placement. Use density to spot accidental repetition, not to hit a quota.

What is a keyword density analyzer?
This tool measures how often each meaningful term repeats in a piece of text and turns it into a share-of-text percentage. Search engines treat keyword repetition as one signal among hundreds: used naturally, repetition is how a page signals its topic; overdone, it can read as keyword stuffing. The analyzer gives you the numbers so you can find that balance before you publish.
