Keyword Density Checker
Analyse keyword frequency and density in any block of text.
About this tool
Keyword Density Checker analyses any text and shows you exactly how often a target keyword appears and what percentage of the total word count it represents. It counts words, characters, and sentences; identifies the top 10 most frequent words; and flags over-optimisation when keyword density exceeds 3%. Paste your blog post, product description, or landing page copy, enter the keyword you are targeting, and instantly see if you are hitting a natural density range — or stuffing too many repetitions.
How to use
- Paste your content into the text area.
- Type your target keyword into the keyword field.
- Review the density percentage, frequency count, and top-word breakdown.

FAQ
What is keyword density?
Keyword density is the percentage of times a target keyword appears in a piece of text relative to the total word count. A density of 1–2% is generally considered natural. Above 3–4% starts to look like keyword stuffing, which can trigger search engine penalties.
Is there an ideal keyword density for SEO?
Google has not published an official ideal density. Most SEO practitioners aim for 1–2% for the primary keyword, but semantic relevance and natural writing quality matter far more. Write for humans first — the density metric is a sanity check, not a target.
Does the checker count exact matches or partial matches?
The checker counts exact case-insensitive matches. If your keyword is 'digital marketing', only that exact two-word phrase is counted, not individual occurrences of 'digital' or 'marketing' separately.
What are stop words?
Stop words are common function words like 'the', 'and', 'is', 'in', and 'of' that carry little meaning on their own. The top-words list in this tool filters them out so you see the most meaningful terms in your content, not just the most frequent grammar words.
Should keyword density differ between a homepage and a blog post?
Blog posts and long-form content naturally have more room for keyword repetition, but the density percentage should stay similar across page types (1–2%). A 500-word product page and a 2000-word blog post should both feel natural — the total count will differ but the density percentage stays consistent.
