Free On-Page Content Audit

Keyword Density Checker & SEO Content Analyzer

Paste article copy or fetch a public URL to measure focus-keyword usage, repeated phrases, word variety and possible stuffing — without treating density as a ranking score.

Analyse content

No sign-up required

Pasted text is analysed first. If the box is empty, the checker follows up to five public HTTP/HTTPS redirects and extracts visible text from the server-returned HTML. Client-rendered copy may be missing unless you paste it.

Safe fetch design: private IP ranges, localhost/internal hostnames and non-standard ports are blocked. Redirects are revalidated before each request. Analysis stays on this server.

About this free SEO tool

Measure Keyword Usage Without Turning Density Into a Myth

This keyword density checker tokenizes English-oriented page copy, counts repeated terms and phrases, and reviews a focus keyword if you provide one. It can work from pasted text or from the visible server-rendered HTML of a public URL.

The score is an editorial checklist: length, variety, focus-term presence, stuffing risk and sentence shape. A page can be useful and rank well without a perfect score. Density is a revision aid, not a ranking prediction.

What this checker reviews

  • Total tokens, content words and unique terms.
  • Focus keyword count, density and first occurrence.
  • Secondary phrases you add as extra keywords.
  • Top unigrams plus two- and three-word n-grams.
  • Consecutive repeats and one-term dominance.
  • Stop-word share, sentence length and reading time.

How density is calculated

For a focus phrase, density is (occurrences × words in the phrase ÷ total tokens) × 100. The top-keyword table uses content words only, after common English stop words are removed, so “the” and “and” do not crowd the list.

Stuffing versus emphasis

Repeating a phrase in a title, an early sentence, a heading and a close is often natural. Looping the same two words through every paragraph is not. The checker flags very high densities and consecutive repeats so you can reread those passages.

URL mode versus paste mode

Paste mode is best when you already have the draft. URL mode uses the same public-host, public-port and redirect checks as the Meta Tag Checker, then strips script and style nodes before counting words.

Transparent methodology

How the Content Score Works

The 100-point score adds usable length (up to 15), lexical variety (10), focus-term presence and a mid-range density (up to 27), lack of extreme repeats (12), extracted phrases (13), readable sentence length (8), a balanced stop-word share (7), multiple sentences (5) and a successful URL fetch when used (5). Critical stuffing or empty samples cap the score.

Important: this is an ihaan.org editorial audit score. It does not reproduce or predict Google, Bing or any other platform’s ranking algorithm, and it does not replace a human edit.
Frequently asked questions

Keyword Density Checker FAQs

What is keyword density?
Keyword density is the share of a text taken up by a word or phrase. This checker reports count and percentage after normalizing case, stripping markup and splitting on word boundaries.
What keyword density should I aim for?
There is no official search-engine target. This tool treats roughly 0.5% to 3% as a practical editorial range for a focus phrase and flags values around 4.5% or higher as a stuffing risk. Write for readers first.
Does higher density help rankings?
No reliable public ranking system publishes a density quota. Repeating a phrase until the copy sounds unnatural can hurt readability and trust. Use density as a revision check, not a ranking lever.
How does this checker count words?
It lowercases the text, removes most punctuation, and splits on whitespace. Very short tokens are ignored in the content-word list. Common English stop words are excluded from the top-keyword table but still counted in the full token total used for focus-phrase density.
Why can pasted text differ from a fetched page?
URL mode reads server-returned HTML and drops script, style and similar elements. Content injected only after JavaScript runs will not appear unless you paste the rendered text yourself.
Are two-word and three-word phrases search keywords?
They are repeated n-grams in the content-word stream. They help you spot stock phrases and accidental loops. They are not a promise of how a search engine tokenizes queries.
