How the Frequency Analyzer Works

The tool splits your text into individual tokens, strips punctuation, and counts each unique word. Results are displayed in a ranked table showing the word, its frequency count, and its percentage of total words. The search box lets you pinpoint any specific term instantly.

For Writers: Spot Repetitive Language

During the drafting phase, writers habitually fall back on the same vocabulary. Pasting a finished draft into the analyzer exposes these patterns objectively. If "effective" appears 18 times in a 600-word article, you can open a thesaurus and swap variants like "potent," "efficient," or "impactful" — immediately sharpening your prose.

For SEO: Monitor Keyword Density

Search engines analyze word frequency to understand what a page is about. Over-repeating a target keyword — known as keyword stuffing — triggers ranking penalties. The frequency analyzer helps you stay in the optimal 1–2% density range for your primary keyword while maintaining natural-sounding copy.

How to Use the Frequency Analyzer

Paste your text into the box and click Analyze Words to see a ranked table of the words you use most, or Analyze Characters to see which letters, digits and symbols appear most often. Each row shows the item, how many times it occurs and a small bar so you can compare counts at a glance. To check one specific word, type it in the search box and the tool tells you how many times it appears and what share of your total word count that represents.

A Worked Example

Paste this sentence:

The cat saw the other cat. The end

The word table lists the (3), cat (2), then end, other and saw (1 each). Searching for "cat" reports that it was found 2 times, which is 25.0% of the 8 words in the text.

How the Counting Works

  • Words are compared in lowercase, so "The" and "the" are counted together.
  • Letters and numbers from any language count as word characters, and a contraction such as "don't" is kept as a single word.
  • Every word is counted, including "the", "and" and "of". The tool does not filter out common words, so they often sit at the top of the table. Look past them to the content words below.
  • Only the 50 most frequent items are displayed. Items with equal counts are listed alphabetically.
  • The character view ignores spaces and line breaks and treats uppercase and lowercase letters as different characters.

Practical Tips

  • Editing your own writing: scan the table for filler words such as "very", "just" and "really". If one appears far more often than you expected, vary or cut it.
  • Checking keyword use: search for your target phrase's main word and read the percentage. Treat any density figure as a rough guide, not a target to hit. Writing naturally for readers matters far more.
  • Spotting overused phrases: paste one section at a time. Comparing the table for an introduction against the conclusion often shows which words you lean on.
  • For total length, use the Word & Character Counter. To find repeated lines rather than repeated words, try the Duplicate Highlighter.

Frequently Asked Questions

What is keyword density and why does it matter for SEO?
Keyword density is the percentage of times a target keyword appears relative to the total word count. Search engines use it to understand page relevance. Ideal density is typically 1–2%; exceeding 3–4% risks being penalized for keyword stuffing.
How do I find crutch words in my writing?
Paste your draft into the Frequency Analyzer and sort by highest frequency. Words appearing disproportionately often — especially vague filler words like "very," "just," or "really" — are your crutch words. Replace them with stronger, more specific vocabulary.
Can I use this tool to check SEO keyword density?
Yes. Paste your article or page content and search for your target keyword in the search box. The tool will show you exactly how many times it appears and its percentage of total word count.
Does the frequency analyzer count every word including "the" and "a"?
Yes, it counts all words including common articles and prepositions. This gives you the complete picture. You can search for any specific word using the search box to focus on what matters most.
Are accented letters and contractions handled correctly?
Yes. Letters and numbers from any language are treated as part of a word, so "café" is one word. A contraction such as "don't" is also counted as a single word.
Why only 50 results?
The word and character tables show the 50 most frequent items, which is enough to reveal overused words and the overall pattern. You can still search for any individual word with the search box, even if it is not in the top 50.
