Keyword Density Checker

What Is a Keyword Density Checker?

A keyword density checker analyzes a block of text (or a live webpage) and calculates what percentage of the total word count each keyword or phrase represents. It's used to spot both under-optimization (a target keyword barely appears) and over-optimization (keyword stuffing that can look spammy to search engines and readers alike).

How Our Keyword Density Checker Works

Paste your content or enter a URL, and the tool counts every word and phrase occurrence, then calculates each one's percentage share of the total text. Results are typically sorted by frequency so the most repeated terms — intentional or not — are immediately visible.

How to Use the Keyword Density Checker

• Paste your content, or enter a URL to analyze a live page
• Click Check Density
• Review the list of keywords/phrases ranked by frequency and percentage
• Adjust your content if a target keyword is under- or over-used

Key Features

• Single-word and phrase analysis — checks both individual keywords and multi-word phrases
• URL analysis mode — check a live published page, not just draft text
• Percentage breakdown — see exactly how much of your content each term makes up
• Stuffing detection — quickly spot terms that are unnaturally repeated

Who Uses This Tool

SEO writers check draft content before publishing to confirm target keywords appear at a natural frequency. Content editors review existing pages that may be under-performing due to keyword stuffing. Site auditors scan a competitor's top-ranking page to understand their keyword usage pattern.

Frequently Asked Questions

Is there an ideal keyword density percentage?
There's no single magic number modern search engines target; the safest approach is writing naturally for readers and letting keyword frequency follow from that, rather than hitting a fixed percentage.

Can keyword stuffing hurt my rankings?
Yes, unnaturally repeating a keyword can trigger spam signals and also makes content harder to read, which increases bounce rate.

Does this check both my own content and live pages?
Yes, you can paste raw text or enter a URL to analyze a page that's already published.

Is this tool free?
Yes, checking keyword density is completely free with no signup required.
