See Which Words Dominate Any Page

Keyword density tells you whether a page is on-topic, off-topic, or accidentally optimized for the wrong term. The checker scans any URL or pasted text and lists the top 30 keywords with frequency bars.

Switch to 2-word and 3-word phrases to find the long-tail opportunities that single-keyword analysis misses.

Why Use Our Keyword Density Checker?

URL or Pasted Text

Two input modes: enter any public URL and we fetch the page server-side, strip out scripts / styles / SVG / iframes / templates, then prefer the `<main>` or `<article>` element so navigation and footer text do not pollute the analysis. Or paste any block of text directly, drafts, briefs, blog posts, descriptions, for instant analysis without any fetch.

Live Filters

Adjust the analysis on the fly. Switch between 1-word, 2-word, and 3-word phrase mode; raise the minimum word length to skip noise (1+, 3+, 4+, 5+); toggle a 130-word English stop-word filter so words like "the", "and", "of", "for", "is" do not dominate the chart. Every filter change re-renders the table instantly without re-fetching.

Visual Density Bars

The result table shows the top 30 keywords with rank, the keyword itself, a proportional density bar, raw count, and density percentage. Bars are scaled to the most-frequent keyword so you can spot the dominant terms at a glance, useful for identifying over-optimization (single keyword above 4-5%) or thin coverage (top keywords all clustered below 1%).

Privacy First

Pasted-text mode runs entirely in your browser, no upload, no logging. URL mode makes one outbound fetch from our server to the URL you enter, and the result is rendered inline with no database write. Use it freely for client audits, competitor research, and pre-publication SEO checks on unreleased copy.

FAQ

Frequently Asked Questions

Common questions about keyword density and using this tool.

What is a healthy keyword density?
There is no exact target, modern search engines rank on relevance and topical depth, not raw keyword count. As a sanity check: a primary keyword in the 1-2.5% range is normal, 3-4% is heavy but not penalised on its own, and 5%+ tends to look like keyword stuffing to both readers and ranking algorithms. The more useful signal is whether your top 1- and 2-word phrases reflect the topic you intended; if a competitor article ranks for "vegan protein powder" and your top phrase is "great taste", you have a topical-coverage gap, not a density problem.
Why does the URL analysis sometimes look different from what I see on the page?
The tool extracts text from the rendered HTML, prioritising `<main>` / `<article>` / `#content` / `#main` and falling back to `<body>`. Scripts, styles, SVGs, iframes, and templates are removed. So if a page renders most of its content via JavaScript after page load (single-page apps, heavy client-side rendering), the analysis only sees the server-rendered shell, which is also exactly what most search-engine crawlers see for a first pass. Server-rendered articles, blog posts, and product pages give the most accurate result.
What does "stop words" mean?
Stop words are extremely common words, "the", "and", "of", "for", "is", "in", "you", "it", that appear in almost every English text and dilute the keyword chart with grammatical noise. With the toggle on (default), those words are filtered out before counting, so your top results are content words like nouns, verbs, and adjectives. Turn it off when you want a raw frequency analysis (rare, but useful for academic linguistics work or stylistic analysis).
Are 2-word and 3-word phrases more useful than single words?
Usually yes. Single-word density is dominated by topical nouns ("vitamins", "running", "tax") that are too broad to be commercially actionable. 2- and 3-word phrases are closer to actual search queries, "vitamin d benefits", "running shoes review", "tax filing deadline", and surface the long-tail opportunities a piece of content is well-positioned for. Run a 1-word pass for topic confirmation, then switch to 2- and 3-word for opportunity hunting.
