Keyword Density Checker

What the Keyword Density Checker Helps You Do

This keyword density checker measures total word count, target-keyword frequency, and top repeated words from the text you paste into the page.

It works best as a writing review aid, not as a ranking formula, because modern SEO depends on relevance, structure, and intent far beyond raw density alone.

How to Use the Keyword Density Checker

Paste your content into the text area.
Enter the target keyword or phrase you want to review.
Check the count, density percentage, highlighted matches, and top repeated non-stop words.

Common Use Cases

Spot-checking whether a target phrase appears too rarely or too aggressively in a draft.
Reviewing repeated terms before publishing a page or article.
Comparing revised versions of copy during an on-page SEO edit.

Notes and Limitations

The tool counts total words from the pasted text, calculates exact keyword matches, and excludes common stop words from the top-frequency list.
SEO checker and analyzer tools on ToolPeg are best used for drafting, self-review, or lightweight audits. Tools that normally require search-index access, live crawling, or third-party datasets may be directional rather than authoritative.
Density by itself is not a ranking target or guarantee of search performance.
The analysis only covers the text you paste and does not inspect headings, links, entities, or live page structure automatically.
Use this as a writing check, then confirm quality with live SERP intent, readability, internal linking, and full on-page review.

Frequently Asked Questions

What is a good keyword density percentage?

There is no universal target. Most SEO practitioners suggest keeping keyword density between 1-3% to sound natural. Modern search engines prioritize relevance and user intent over exact density, so focus on readability first.

Does keyword density affect SEO rankings?

Not directly. Search engines moved beyond simple keyword counting years ago. However, checking density helps you spot keyword stuffing or under-usage, both of which can hurt content quality and user experience.

What are stop words and why are they excluded?

Stop words are common words like 'the', 'is', 'and', and 'in' that carry little meaning on their own. The tool excludes them from the top-frequency list so you can focus on the meaningful terms that actually define your content.
