How to Use the Keyword Density Checker

  1. Optionally enter your target keyword (the primary keyword you are optimizing this page for) in the first field.
  2. Copy all the text content from your page — or paste the raw HTML — into the content box.
  3. Click Analyze. The tool strips HTML tags, counts all meaningful words and 2-word phrases, and calculates frequency percentages.
  4. Review the target keyword density. Aim for 1–2.5% for primary keywords. Anything above 3.5% may trigger over-optimization signals in Google’s spam detection.

What is the Ideal Keyword Density in 2024?

Modern SEO does not have a single correct keyword density number. Google’s algorithms have moved far beyond counting keyword repetitions — they evaluate semantic coverage, entity presence, and topical completeness. A page that uses the target keyword once but comprehensively covers related entities, attributes, and predicates will outrank a page with 3% keyword density but thin semantic content.

That said, extremely low density (below 0.5% for the primary keyword) may indicate the page does not clearly address the target topic. A practical guideline: mention the primary keyword in the title, H1, first paragraph, at least one H2, and naturally throughout the body. This typically produces a density of 1–2% without deliberate stuffing.

Frequently Asked Questions

Is keyword stuffing still a Google penalty risk?
Yes. Google’s spam policies explicitly prohibit “unnecessarily repeating keywords in an unnatural way.” Pages where the keyword density exceeds 4–5% typically read unnaturally and Google’s quality systems detect this pattern. Modern over-optimization penalties are largely automatic and algorithmically applied rather than manual actions.
Should I count keywords in headings differently?
Headings carry more semantic weight than body text for keyword signals. A keyword in an H2 is more significant than the same keyword appearing in a body paragraph. This tool shows total content density — you should additionally verify the keyword appears in at least the H1 and one H2 heading.
What are stop words and why are they excluded?
Stop words are common function words (the, a, and, is, in, of, etc.) that carry no semantic meaning and would skew density calculations if counted. This tool excludes an expanded English stop word list, ensuring the density percentages reflect only meaningful content words.
