How to Use This Keyword Frequency Counter

Paste your text: Copy any text — a blog post, landing page, essay, resume, or email — and paste it into the "Input Text" field above.
Set target keywords (optional): To focus on specific terms, enter comma-separated keywords in the "Target Keywords" field. Leave it blank to analyze every word in the text.
Configure options: Enable case-insensitive matching (default), filter out common stop words like "the" and "and," exclude numbers, set a minimum word length, and choose how many results to display.
Count and export: Click "Count Keywords" to see the ranked frequency table. Use "Copy" to paste tab-separated results into a document, or "CSV" to download a spreadsheet-ready file.

Pro Tips

Target keywords for SEO: Enter your SEO keyword list as comma-separated targets. The tool shows how many times each keyword appears, helping you review keyword density at a glance.

Set min word length to 3 or 4: This filters out short function words even when stop words are disabled, giving you a cleaner view of meaningful terms.

Combine with the file version: For TXT and PDF files, use the Keyword Frequency Counter for Files instead — it handles uploads with the same analysis engine.

Browser-based processing: The counter runs on the page and calculates results from the text you paste.

Read the Share column for SEO: A keyword density between 1% and 3% is a common review range for SEO copy. If your target keyword exceeds 5%, consider reducing repeated uses to avoid keyword-stuffed writing.

Compare a resume with a job description: Paste the job posting first and note the top keywords. Then paste your resume to see which relevant terms are missing or underused.

FAQ

Q. How do I count keyword frequency?

Paste your text into the "Input Text" field, set any filters such as stop words, minimum length, or target keywords, and click "Count Keywords." The tool generates a ranked table showing each keyword's count and percentage share.

Q. What is keyword density and how is it calculated?

Keyword density is the percentage of times a specific word appears relative to the total word count. For example, if "marketing" appears 10 times in a 500-word text, its density is 2%. This tool calculates density automatically in the "Share" column.

Q. What are stop words and why should I filter them?

Stop words are high-frequency, low-meaning terms like "the," "is," "and," and "of." Filtering them removes clutter from your results so you can focus on the words that define your content's topic.

Q. How do I check keyword density for SEO?

Paste your content, enter comma-separated target keywords in the "Target Keywords" field, and click "Count Keywords." The results show each target keyword's count and density percentage, so you can review how often those terms appear.

Q. Can I export the frequency results?

Yes. Click "Copy" to copy tab-separated results to your clipboard, or click "CSV" to download a spreadsheet-ready file. Both formats work with Excel, Google Sheets, and other data tools.

About the Keyword Frequency Counter

The Keyword Frequency Counter analyzes how often each word appears in your text. Paste content such as a blog post, landing page, essay, resume, or marketing email, then get a ranked table showing each word's count, percentage share, and visual distribution.

This tool includes filtering options to focus on the terms you need. Target specific keywords to check SEO density, filter out common stop words like "the" and "is," set a minimum word length to skip short particles, and exclude numbers from the results. The JavaScript counter runs on the page and calculates results from the text you paste. When you are done, export the results as a CSV file for review in Excel or Google Sheets.

Common Use Cases

SEO content analysis: Check whether your target terms appear in a typical review range — often 1% to 3% — without making the copy feel keyword-stuffed. Use the "Target Keywords" field to isolate only your SEO terms and review their counts and density percentages at a glance.
Academic writing: Identify overused words in essays, research papers, or theses to improve vocabulary variety. Enable stop-word filtering and set a minimum word length of 4 to focus on substantive terms, then replace repeated words with synonyms.
Competitor research: Paste a competitor's landing page copy and see which keywords they emphasize most. Compare their top keywords against your own content to identify gaps — terms they target that you have not yet covered.
Resume optimization: Compare your resume with a job description to find missing or underused keywords. Focus on nouns and industry-specific terminology that recruiters may search for.
Content auditing: Analyze blog posts or marketing copy to verify that brand terms, product names, and key messages appear consistently across all materials. Enter your brand terms in "Target Keywords" for a focused audit.
Writing improvement for authors: Spot unintentional repetition in fiction, creative nonfiction, or long-form articles. Seeing your most-used words helps you diversify your vocabulary and keep readers engaged.

What Is Keyword Frequency and Why Does It Matter?

Keyword frequency measures how many times a specific word appears in a body of text. It is a useful metric in SEO, academic research, content strategy, and data analysis. In SEO, keyword frequency — often expressed as keyword density, or the percentage of total words a keyword occupies — helps you review whether target terms appear often enough to signal relevance without making the copy feel repetitive.

A common SEO review range is 1% to 3% keyword density. Below 1%, the term may be too sparse to stand out in the text. Above 5%, repeated use can make the copy look keyword-stuffed. This tool calculates density in the "Share" column, so you can check your content as you edit. For non-SEO applications, keyword frequency reveals word repetition patterns, highlights dominant themes, and supports editing decisions.

Metric	Description	Typical SEO Range
Keyword Count	Number of times a word appears	Varies by content length
Keyword Density (Share)	Count / (Total Words − Filtered Words) × 100%	1% – 3% (common review range)
Overuse check	Density above this level may indicate keyword-stuffed copy	> 5%
Total Words	All words in the input text	N/A
Unique Words	Number of distinct words after filtering	Higher = more vocabulary variety

Tips for Accurate Keyword Analysis

Enable stop-word filtering by default: Common words like "the," "is," and "and" appear in almost every English text and can hide the words that define your topic. Keep "Filter stop words" checked unless you need a complete count of all words.
Use Target Keywords for SEO checks: Instead of scrolling through hundreds of results, enter your SEO keyword list in the "Target Keywords" field. The tool isolates only those terms and shows their density, so you can review their presence in the text.
Set min word length to 3 or higher: Short words (1–2 characters) are rarely meaningful for content analysis. Setting a minimum length of 3 filters out short function words and other non-substantive terms, even when stop-word filtering is disabled.
Compare before and after revisions: Run the analysis on your original draft first, then again after editing. Comparing the two keyword lists shows whether your edits reduced repeated terms and increased vocabulary variety.
Export to CSV for team review: The CSV download includes every keyword's count and density percentage, so you can share results with colleagues or include them in content strategy reports.
Try case-insensitive mode for most analyses: The default case-insensitive setting treats "Content" and "content" as the same word, which is usually what you want. Disable it only when you need to distinguish proper nouns from lowercase terms — for example, "Apple" (the brand) vs. "apple" (the fruit).
