About the Keyword Density Checker
Keyword density is the percentage of times a keyword appears in your content relative to the total word count. For example, if "SEO tools" appears 5 times in a 500-word article, its density is 1%.
While Google does not use keyword density as a direct ranking factor, over-stuffing keywords — a practice known as keyword stuffing — can trigger manual penalties or algorithmic downgrades. A natural density of 1–3% for your primary keyword is generally considered safe, while anything above 5% for a single term may be flagged as spammy.
How to Check Keyword Density
Paste Your Content
Copy the full text content of your page (strip HTML tags first) and paste it into the text area.
Configure Options
Set a minimum word length to filter short words, choose how many top keywords to display, and toggle stop-word filtering.
Analyse
Click "Analyse Keyword Density" to see word counts, density percentages and a visual bar chart. Keywords above 3% are highlighted in red.
Export Results
Export the full frequency table as a CSV file for further analysis or reporting.
Frequently Asked Questions
There is no universally ideal keyword density — Google's algorithms are sophisticated enough to understand context. As a guideline, most SEO professionals aim for 1–2% for a primary keyword. The most important thing is that your content reads naturally for humans. Use your target keyword where it makes sense, including in the title, first paragraph, headings and naturally throughout the body.
Stop words are extremely common words that carry little meaningful information on their own — words like "the", "is", "at", "which", "on", "a", "an". Search engines historically ignored stop words to reduce index size and focus on meaningful terms. Filtering them in this tool gives you a cleaner keyword frequency picture.
This tool currently analyses single-word (unigram) density, which is useful for identifying term overuse. For phrase-level analysis (bigrams, trigrams), you can use the Word Frequency Counter and look for repeated adjacent terms manually. A future update will add n-gram analysis.
Keyword density as a metric is largely obsolete as a positive ranking signal. However, it remains useful as a negative check — extremely high density (above 5–7%) for a single term is a clear indicator of keyword stuffing, which can harm rankings. Use this tool to confirm your content is balanced rather than to hit a specific target number.
