Word Frequency Counter

What is a word frequency counter and why is it useful?

A word frequency counter scans text and tallies how many times each individual word appears, presenting results ranked from most to least common. The use cases span multiple disciplines. For SEO professionals, it reveals whether a target keyword appears at the right density — frequently enough to signal relevance to search engines, but not so often it triggers over-optimisation penalties. For writers and editors, it exposes repetitive vocabulary that needs variation. For researchers, it identifies dominant themes without reading an entire document. For students, it confirms that key terms appear with the right emphasis throughout an essay. Start with a total word count in our Word Counter before diving into frequency analysis to understand your text's overall scale.

What are stop words and should I filter them?

Stop words are extremely high-frequency function words present in virtually every English text: articles like "the" and "a", prepositions like "in", "on" and "of", conjunctions like "and" and "but", and common verbs like "is" and "are". These words dominate frequency tables but carry no meaningful information about a document's topic. The "Filter stop words" option removes them so you see only substantive words that reveal actual content. Disable filtering only when doing linguistic research where function word frequency is meaningful — for example, authorship attribution studies or stylometric analysis. For most SEO and content analysis work, keep filtering enabled for cleaner results.

How is keyword density calculated?

The percentage column shows each word's frequency as a proportion of total word count: count ÷ total words × 100. For SEO, a target keyword at 1–2% density is generally healthy. Below 0.5% the term may be too sparse to register as a topic signal; above 3–4% may be flagged as keyword stuffing by search algorithms. Paste your draft content and check the percentage next to your target term before publishing. Pair this with our Character Counter to simultaneously verify meta description and title length, and our Reading Time Calculator to confirm your content hits the right reading time for your target audience.

What does the minimum word length filter do?

The minimum length field excludes words shorter than the specified character count from results. The default of 2 removes single-letter words like "a" and "I". Setting it to 3 or higher further reduces noise from two-letter words that appear frequently but add little analytical value. For SEO and content analysis, a minimum length of 3 combined with stop word filtering gives the clearest view of meaningful vocabulary. For linguistic research requiring complete frequency data, set the minimum to 1 and disable stop word filtering. After cleaning results, check total word count with our Word Counter.

Can I export the frequency results?

Yes. "Copy as CSV" copies the full results table to your clipboard in comma-separated format, ready to paste into a spreadsheet. "Download CSV" saves the same data as a .csv file you can open directly in Microsoft Excel, Google Sheets or any spreadsheet application for further analysis, charting or sharing. The CSV includes columns for rank, word, count, and percentage. For slug-friendly URL generation from your top keywords, pass them through our Text to Slug converter to create clean URLs from high-frequency terms.

How does this differ from the keyword density in the Word Counter?

The Word Counter includes a quick keyword density panel showing the top 15 terms as visual bars — useful for a fast overview during writing. This Word Frequency Counter provides a full sortable, filterable table with every word in your text, exact counts, precise percentages, frequency bar charts, CSV export, case sensitivity control and minimum word length filtering. It is the right tool for a thorough content audit or research task rather than a quick glance. For real-time character limits on top of word frequency, use the Character Counter simultaneously in another tab.

Does case sensitivity affect the results?

By default, the tool is case-insensitive: "The", "the" and "THE" are counted as the same word. This is appropriate for most writing analysis. Enabling case-sensitive mode treats each capitalisation variant as a distinct word — useful for code analysis, data with deliberate case distinctions, or technical documentation where "API" and "api" carry different meanings. Toggle case sensitivity with the checkbox in the toolbar and results update immediately without needing to re-paste your text.

Is this tool useful for academic writing?

Yes. Frequency analysis is a practical editing technique for academic work. Paste your essay and sort by frequency to find overused words that could be replaced with synonyms for more varied vocabulary. Check that thesis keywords appear with appropriate frequency relative to total word count. Identify filler phrases that inflate length without adding meaning. After editing, verify your final word count with our Word Counter, proofread for spelling errors with our Spell Checker, and estimate how long your paper will take to read with our Reading Time Calculator before submission.

Can I use this for SEO content audits?

Yes — this is one of the primary professional use cases. Paste a competitor's page or your own draft and scan the frequency table for keyword usage patterns. Check that your primary keyword and related semantic terms appear at healthy density. Look for topic gaps where important terms you expected to see are missing or underrepresented. Export the results as CSV to include in a content brief or SEO audit report. For a complete on-page SEO check, combine this tool with our Character Counter for meta length, our Reading Time Calculator for content depth, and our Text to Slug for URL optimisation.
