Keyword Density Checker – ToolPremier

Ideal keyword density: 1–3% for target keywords · avoid keyword stuffing

How it works
Convert in three steps

1. Paste your content

Drop in a blog post, product description, landing page copy, or any block of text you want to analyze. The full page body works better than excerpts.

2. Review the frequency table

See every word and phrase ranked by frequency and density percentage. Stop words (the, and, a, etc.) are filtered out by default so the meaningful terms surface first.

3. Adjust your content

Identify keywords that appear too often (risking over-optimization) or too rarely (a missed opportunity), then edit your copy accordingly.

FAQ
Common questions
Keyword density is the percentage of times a specific word or phrase appears relative to the total word count of a piece of content. A keyword appearing 10 times in a 1,000-word article has a density of 1%. It is a simple measure of how prominent a term is in the text – useful for spotting both over-repetition and gaps.
There’s no universally correct target. A density of 1-2% for a primary keyword is a common guideline for natural-sounding content, but the number is far less important than whether the keyword appears in contextually relevant positions – the title, H1, first paragraph, and subheadings. Focus on topical coverage and natural usage rather than hitting a specific percentage.
Google doesn’t publish a specific penalty threshold for keyword density, but content that repeats the same term unnaturally will trigger quality signals that suppress rankings. If reading the text aloud sounds repetitive or forced, it’s over-optimized regardless of what the density number says. Use this tool to find anomalies – terms that appear far more or far less than everything else – rather than to hit a target number.
Single-word analysis shows how often individual terms appear. Phrase analysis (2-3 word combinations) is more useful for SEO because it reflects how people actually search – not just shoes but running shoes for women. Review 2-word and 3-word phrase density alongside single words to get a complete picture of topical coverage.

About the Keyword Density Checker
Keyword density analysis has a bad reputation because it’s been misused – treated as a target to hit rather than a diagnostic to run. Used correctly, it tells you something useful: whether your content is topically coherent (a page about image compression that never uses the words file size has a gap), whether you’re repeating yourself unnaturally, and whether related terms and synonyms are present alongside the primary keyword. This checker runs the analysis in your browser and returns a sortable frequency table for single words and common phrases. Filter out stop words, sort by density, and use the results to make editorial decisions – not to stuff keywords, but to close gaps and remove unintentional repetition.
Benefits
  • Word and phrase frequency table - single keywords, 2-word, and 3-word combinations all analyzed.
  • Density percentages - see each term as a share of total word count, not just raw frequency.
  • Stop word filtering - common words removed by default so meaningful terms surface immediately.
  • Runs in your browser - paste any draft privately, no content uploaded to a server.
Privacy
All analysis runs client-side. The content you paste is processed locally in your browser and never transmitted to any server.
