How to Use the Keyword Density Checker

  1. Paste your article text into the box.
  2. Read the 1, 2 and 3-word tables for the leading phrases.
  3. Toggle stop words or the minimum length to inspect exact phrasing.
  4. Rewrite passages where one term dominates past 3 percent.
  5. Click Copy Report or Download Report to keep the numbers.

Reading the Tables Like an Editor

A healthy table mirrors the article brief: the target topic leads at a modest share, supporting terms follow, and filler stays invisible. When an unrelated word climbs the ranks, the draft has drifted; when the lead term passes 5 percent, the prose likely repeats itself.

Phrases beat single words

The bigram and trigram columns show what the page is actually about in a way single words cannot. A post targeting espresso machines should surface machine names and buying phrases there, not just machine. Cross-check the draft length and reading load with the Word Counter, then shape the snippet that carries the terms with the Meta Tag Generator.

Honest limitations

Counting is literal: bean and beans rank separately, and synonyms never merge, so related terms split their share across rows. Density describes repetition only; it cannot judge relevance, accuracy or writing quality. Use the tables as an editing lens, not a ranking formula.

Privacy and Client-Side Security

Privacy Guarantee: All counting occurs locally inside your browser. Your article text is never transmitted, stored, or recorded on remote servers.

Many online analyzers send your drafts to a server for processing. TinyToolzz takes a different approach: every step runs in the page itself with plain JavaScript string operations.

Because nothing is uploaded, there is no waiting, no account, and no copy of your articles retained anywhere. Your text exists only in the tab memory and is discarded when you close the page or click Clear.

Frequently Asked Questions

What is keyword density?
Keyword density is the percentage of times a word or phrase appears relative to the total word count. A top term between 1 and 3 percent reads naturally in most articles; far above that usually means the text was written for crawlers rather than readers.
What is keyword stuffing?
Keyword stuffing means overloading a page with a target phrase to manipulate rankings, often in unreadable sentences or hidden text. Search engines penalize it, so when one term dominates the table here, rewrite for variety instead of adding more repetitions.
Why check 2-word and 3-word phrases?
Single words are ambiguous: coffee can mean beans, shops or brewing guides. Two and three-word phrases reveal the real topics, such as coffee beans versus coffee shop, and mirror the longer queries searchers actually type.
Should stop words be excluded?
Yes for analysis. Words like the, and and of always top raw counts without saying anything about the topic. Filtering them exposes the content words; switch the toggle off only to inspect exact-match phrasing.
What density should I aim for?
There is no magic number. Modern ranking weighs topical coverage and page quality far more than repetition counts, so treat 1 to 3 percent for the lead term as a sanity range and prioritize readable, complete coverage of the subject.
Is my article text uploaded to a server?
No. All counting happens locally in your browser with JavaScript. Your text is never transmitted, stored or logged anywhere. Closing the tab or clicking Clear removes it from memory immediately.
