Keyword Density Checker

About the Keyword Density Checker

Keyword Density Checker counts every word in your article, filters out common English stopwords (about 180 of them — "the", "and", "is", etc.) and ranks the most-frequent terms by density, where density = (count ÷ total words) × 100. It is essential for two SEO tasks at once: spotting keyword stuffing (anything above ~3% for a single phrase risks an algorithmic penalty) and verifying that your target phrase actually appears often enough to signal topical relevance. Configure the top-N output between 5 and 100, toggle the stopword filter (useful for non-English content) and copy the result table to a spreadsheet for further analysis.

How to use

1. Paste your article text into the input box.
2. Choose how many top keywords to display (5–100) and whether to filter stopwords.
3. Click Analyze to see the ranked keyword density table.

Benefits & key features

• Top-N is fully configurable.
• Stopword filter toggleable for non-English content.
• Healthy density for a primary keyword is typically 1–2.5%.
• Works offline once the page is cached.

Pro tip

Run this on a draft before publishing. If your target keyword is not in the top 5, search engines will struggle to understand what your page is about.

Why choose toolsfy for Web & SEO tools?

On-page SEO is still 80% of the ranking battle and can be audited in 30 seconds — yet the typical SEO SaaS wants $49/month to tell you your meta description is 204 characters long. toolsfy's SEO utilities compute the same signals in your browser, against the HTML you paste, with zero account friction and zero data leaving your device.

Common use cases

• Freelance SEOs running a quick pre-launch audit on a client's landing page before it hits production search results.
• Publishers generating a validator-friendly sitemap.xml for a new subdomain in under a minute, without firing up an XML editor.
• Developers producing a spec-correct robots.txt for a staging environment so crawlers stop indexing QA URLs by accident.
