Keyword Density Calculator

Step-by-Step Guide

1. 1Paste Your Content: Copy your article, blog post, product description, or landing page copy and paste it into the text area. The word count, character count, sentence count, and reading time update instantly.
2. 2Configure Analysis Options: Set the minimum word length to filter out very short words. Toggle stop-word filtering on to exclude common filler words like 'the', 'and', and 'is' from the frequency table. Choose your n-gram mode — single words, bigrams, or trigrams.
3. 3Search a Specific Keyword: Type your target keyword or keyphrase into the search field to see its exact count, density percentage, and whether it falls within the recommended 0.5–2.5% range. A warning badge appears if the density exceeds 4%.
4. 4Review the Frequency Table: The sortable table shows every keyword, its occurrence count, and its density. Sort by density to spot over-represented terms. Sort by count to find your most-used words. Use this to confirm your primary and secondary keywords are appropriately distributed.
5. 5Export Your Report: Click Export CSV to download the full keyword table for spreadsheet analysis. Use Export TXT for a plain-text summary. Use Copy to Clipboard to paste results directly into a client report or content audit document.

Pro Tips

• 💡Target a density of 0.5–2.5% for your primary keyword. A well-written 1,500-word article naturally hits this range with 8–37 uses of the main keyword. If you need to force it beyond that, the content is over-optimised.
• 💡Use the bigram analysis to check your secondary keyphrases. Top-ranking content rarely relies on a single keyword — it covers a cluster of 2–4 related phrases that collectively signal deep topical coverage to Google.
• 💡Enable stop-word filtering before exporting keyword reports for clients. It removes noise and keeps the frequency table focused on meaningful terms that actually affect rankings.
• 💡Run the analysis on the top 3 competitor pages for your target keyword before writing. Note which terms appear in their top 20 words that are absent from your own draft — these are likely related terms Google expects to see.
• 💡Check the trigram results for any 3-word phrase appearing more than 3 times in a 1,000-word piece. Natural writing rarely repeats 3-word phrases — if the tool surfaces one, it may be an inadvertent repetition that sounds forced to both readers and algorithms.
• 💡Use speaking time (not just reading time) when writing scripts, podcast show notes, or video descriptions — 130 words per minute is the standard speech rate, and it is a faster way to verify a video's planned length before recording.

Common Mistakes to Avoid

• ✕Don't target a specific keyword density as a hard goal. Google does not use keyword density as a direct ranking factor. The percentage matters only as a signal of over-optimisation — write naturally first, then check the density as a sanity check.
• ✕Don't analyse only your body text. Your title tag, H1, meta description, and alt text all contribute to keyword signals. Run the full page HTML through the tool (or at minimum paste in your body copy plus all headings) for an accurate picture.
• ✕Don't ignore the secondary keyword frequency. An article with a healthy 1.5% primary keyword density but zero appearances of related terms will underperform against a competitor whose content covers the full topic cluster.
• ✕Don't use keyword stuffing in alt text, meta keywords tags, or hidden divs. Google's crawlers detect and penalise these techniques, and the on-page damage far exceeds any perceived benefit.
• ✕Don't compare densities across content of very different lengths. A 0.5% density in a 200-word paragraph means 1 mention. A 0.5% density in a 2,000-word article means 10 mentions — a meaningfully different signal to a crawler.
