Analyze Keyword Density from URL or Text
Check keyword frequency, density percentage, and get actionable SEO insights. Avoid keyword stuffing and optimize your content for search engines.
What Is Keyword Density and Why Does It Matter?
Keyword density is the percentage of times a keyword appears compared to the total word count on a page.
A Metric, Not a Magic Number
Keyword density helps you understand your content's focus and compare it with competitors. There's no "perfect" density — modern SEO prioritizes topical relevance and natural language over hitting a specific percentage.
Why Check It?
Overusing keywords (keyword stuffing) can harm your rankings and make content unreadable. Very low usage may simply reflect that the page uses different wording or focuses on the topic semantically rather than repeating the exact keyword.
How This Tool Works
Analyze any public URL or paste your own text. The tool extracts content, filters stop words, calculates density, and provides actionable SEO feedback with overuse warnings.
Limitations to Know
URL mode fetches publicly accessible pages only. It cannot analyze pages behind login walls or JavaScript-rendered content. Text mode processes your content entirely in your browser for privacy.
Keyword Density Checker
Enter any public URL. The tool will fetch and analyze the page content.
Your text is processed entirely in your browser. Nothing is sent to our server.
Enter keywords or phrases you're targeting to see if they appear in the content.
Privacy note: URL mode fetches the page from our server. Text mode processes entirely in your browser. We don't store URLs after analysis. A temporary rate-limit record is kept for abuse prevention.

Common Issues and What They Mean
If the analysis fails or results look incomplete, check these common causes.
Could Not Fetch URL
FETCH FAILEDThe tool couldn't access the URL you entered.
Solution: Check that the URL is public and accessible. If the site blocks crawlers or requires authentication, the tool cannot access it.
No Words Found
EMPTY CONTENTThe page or text has no significant words to analyze.
Solution: The page may be empty, behind JavaScript rendering, or contain only images/media. Use text mode to paste content directly.
Missing Target Keywords
NOT FOUNDYour target keywords don't appear in the content.
Solution: If the keyword is genuinely relevant to the page, review your headings and main content to see whether the topic is clearly covered. Avoid adding keywords just to increase density.
Keyword Overuse Warning
STUFFING RISKSome keywords exceed 3% density.
Solution: Replace some instances with synonyms or rephrase sentences. Aim for natural language that reads well for humans.
Stop Words Dominating
FILTERED OUTMost words are common stop words (the, a, is).
Solution: This is normal. The tool filters these automatically to focus on meaningful keywords. Review the filtered results.
JavaScript Content Missing
JS LIMITPage content is rendered via JavaScript.
Solution: This tool only analyzes static HTML. For JavaScript-rendered pages, copy the visible text and use text mode instead.

Keyword Density Checker FAQs
Answers based strictly on what this tool does and how keyword density works.
What is an ideal keyword density?
There is no universal ideal keyword density. Focus on clear, useful content and natural language rather than targeting a specific percentage. Modern SEO prioritizes topical relevance over fixed density targets.
What are "stop words"?
Stop words are common words that search engines often ignore (the, a, is, in, etc.). This tool filters them out to provide a more accurate analysis of meaningful keywords on your page.
Is my text data secure?
Yes. Text mode processes your content entirely in your browser — nothing is sent to our server. URL mode fetches the page from our server but doesn't store it after analysis.
Why is the word count different from my word processor?
The tool extracts text from the page body after removing common non-content elements such as scripts, styles, navigation, headers and footers. It also filters out short words (1–2 letters) and stop words from the frequency count.
What does "High Frequency" mean?
Keywords with density above 3% are flagged as high frequency. This is a tool-level heuristic, not a Google ranking threshold. High repetition may make content feel unnatural — review readability rather than targeting a fixed percentage.
Can I analyze multiple pages at once?
No, this tool analyzes one URL or text input at a time. For bulk analysis, run separate checks and export each as CSV for comparison.
Does keyword density still matter for SEO?
Keyword density is less important than it used to be. Modern search engines prioritize topical relevance, user intent, and natural language. However, extreme overuse (stuffing) can still harm rankings.
Can I use this for non-English content?
The analyzer is optimized for English text. Other languages may not be counted accurately because the current word-processing rules and stop-word list are English-focused.
