Keyword Density Checker

Analyze real word & phrase frequency (1, 2 and 3-word) of any page to spot keyword stuffing or gaps.

Fetching live data…

Quick answer

The Keyword Density Checker analyzes the real word and phrase frequency of any live page so you can spot keyword stuffing or thin coverage at a glance. It fetches the page, strips out the HTML and counts how often each one-, two- and three-word phrase appears in the visible text. Everything comes from real, live data — nothing is estimated — so you see exactly which terms a page emphasizes and whether that balance looks natural.

How it works

  1. Paste the URL of the page you want to analyze (for example https://example.com/page).
  2. The tool fetches the live page and extracts only the readable body text.
  3. It tokenizes the words and counts single words, two-word and three-word phrases.
  4. You get ranked frequency tables with counts and density percentages for each.

What it shows

  • Single-word frequency — the most-used individual terms on the page.
  • Two-word phrases — common bigrams that reveal the page's focus.
  • Three-word phrases — longer trigrams that surface specific topics.
  • Count per term — exactly how many times each word or phrase occurs.
  • Density percentage — each term's share of the total word count.
  • Total word count — the overall length of the readable content.
  • Stuffing signals — terms that appear unnaturally often.

Common use cases

  • Catching keyword stuffing — find terms repeated so often they risk a penalty.
  • Checking topical focus — confirm the page emphasizes the right subject.
  • Comparing with competitors — see which phrases ranking pages lean on.
  • Editing thin content — spot where a target term barely appears.

Example

Run a blog post and you might see running shoes appearing 14 times at 2.1% density, while your intended phrase trail running shows up just twice — a clear sign to strengthen the secondary topic without over-using the primary one.

Frequently asked questions

Is the Keyword Density Checker free?

Yes — completely free, no signup and no limits. Analyze as many pages as you like with real, live data.

What is a good keyword density?

There's no magic number, but most natural pages keep a primary term well under 2–3%. Anything dramatically higher reads as stuffing. Aim for natural language and let the term appear where it fits — depth and relevance matter more than a target percentage.
