Repeating a word does not make a page rank, but a draft that repeats one word in every sentence reads badly. Kwebby's Keyword Density Checker shows which words your text repeats most. You paste your content and see the 30 most frequent words with their count, their density and an Over, OK or Low flag. This page explains how the numbers are worked out, which thresholds the tool uses and how to act on them without writing for a counter.
Key Takeaways
- Kwebby's Keyword Density Checker lists the top 30 words in your pasted text, with count, density percentage and a status, and it updates as you type.
- Density is a word's count divided by the total word count, times 100. The minimum word length slider (2 to 8 letters, 3 by default) only decides which words appear in the table.
- The Over and Low flags are the tool's own thresholds (above 5 percent and below 0.5 percent). Google publishes no ideal density.
- The Target Keyword box accepts one word or a phrase such as "email marketing" and counts exact matches.
- The tool reads pasted text only. It does not fetch a URL, and the Top Keywords table lists single words, not two-word or three-word phrases.
- Treat an Over flag as a reason to reread the draft. Google defines keyword stuffing by behavior, not by a percentage.
What Is the Kwebby Keyword Density Checker?
Kwebby's Keyword Density Checker is a free web tool that counts how often each word appears in the text you paste and shows the share each word makes up. It lists the 30 most frequent words, leaves common stop words out of that list, and can check one target word or phrase. Use it to spot repetition before you publish.
You do not need an account, and there is no Analyze button. The table fills in as soon as you paste.
Key Features and How It Works
The tool turns pasted text into a ranked word list in a few steps, all on one screen.
Paste Your Content
Paste text into the Content box. A line under the settings shows how many words were analyzed, so you can see that the count matches what you pasted. Results update whenever the text changes.
Minimum Word Length
The Min word length slider runs from 2 to 8 and starts at 3. Words shorter than the setting are left out of the table. They still count in the total, so changing the slider does not change any density figure. Raise it to push short filler words out of the way, or lower it to 2 if you want short terms counted.
Top Keywords Table
The Top Keywords table has four columns: Keyword, Count, Density and Status. It shows the 30 most frequent words, sorted from most to least common. The page labels the table "stopwords excluded", which means common words such as the, and, of and is are not listed. They still count toward the total, so each density figure is a share of all words in your text.
Status Flags
Each row gets a status. Over means the word makes up more than 5 percent of all words. Low means less than 0.5 percent. OK covers everything in between. These cut-offs belong to Kwebby's tool. They are a quick signal, not a Google rule.
Target Keyword Check
Type a word or phrase into Target Keyword (optional) and a card shows how many times it appears, its density, and a message: Over-optimized (above 5 percent), Consider using more (below 0.5 percent) or Good density. The tool matches whole words in order, so it counts "backlink" and "backlinks" separately, and case does not matter. For a phrase, density is the number of matches times the words in the phrase, divided by the total word count.
Scope and Limits
The tool counts words made of letters or digits in any language, so accented words and numbers count as words. Apostrophes and hyphens inside a word keep it whole, as in don't and e-mail. The table lists single words only, so you will not see two-word or three-word phrases, and you paste text rather than enter a URL.
Why Checking Keyword Density Matters
Keyword density is the number of times a word appears divided by the total word count, shown as a percentage, and it works best as a repetition check. If a 500-word article uses one word 15 times, that word has a 3 percent density. The number alone tells you nothing about quality, but a spike shows where to reread.
Google defines keyword stuffing as filling a page with keywords or numbers to manipulate rankings, and it lists unnatural repetition among the examples. Its SEO Starter Guide adds that repeating the same words, even in variations, tires readers, and that varying your words gives your page more chances to appear for different searches. Neither document gives a target percentage.
How to Use the Keyword Density Checker
Paste your draft, read the top of the table and decide which repeated words to vary. The steps below match the labels on the page.
- Open the tool. Go to the Keyword Density Checker page and find the Content box.
- Paste your content. Copy the body text from your editor. Leave out menus, footers and other page furniture.
- Check the word count. Confirm the words analyzed figure looks right for your draft.
- Scan the Top Keywords table. Look at the top five words and ask whether each one belongs there.
- Add a target keyword. Type a word or phrase, such as "backlink" or "email marketing", into Target Keyword (optional) to see its count and density.
- Adjust Min word length. Move the slider if short words crowd the table. The densities stay the same.
- Edit and recheck. Replace repeated words with synonyms or restructure the sentences, then paste the new version.
Best Practices for Keyword Density
The goal is a draft that reads naturally and still covers the topic.
Read the Table as a Repetition Check
Start with the top five rows. Your main topic word should be near the top, and a surprise word that dominates the list is worth a look. Open the draft, find the repeats, and ask whether a pronoun, a synonym or a shorter sentence would work better.
Do Not Chase a Magic Percentage
Google's keyword stuffing policy describes the problem by behavior: keywords used unnaturally or out of context. It sets no ideal frequency, so a target of "2 percent" from a blog post is a guess. Write for the reader first, then use the tool to check for overuse.
Use Related Terms
Pages that cover a topic fully use many related words. If your article on email marketing never mentions subject lines or open rates, the table will show that gap as a short list of thin vocabulary. Add the missing terms where they help the reader.
Place Key Terms Where Readers Look
Put your main term in the title, the first paragraph and a few headings, then let the body vary. Kwebby's Meta Tag Generator helps you write the title and description that carry your main phrase.
Common Mistakes
- Expecting plurals to match. "Backlink" does not match "backlinks". Check each form you use.
- Pasting navigation text. Menus and footers add repeated words that are not part of your article.
- Ignoring plural forms. "Tool" and "tools" count separately, so add them together by hand.
- Rewriting to hit a number. If a sentence reads worse after the edit, undo it.
Common Use Cases
- Writers and editors check a draft for words they lean on too often.
- SEO teams review product descriptions and category copy before a release.
- Content managers paste a published competitor article to see which words it repeats most.
- Students find repeated words in an essay and swap them for better ones.

Frequently Asked Questions (FAQs)
What is keyword density?
Keyword density is the percentage of a text taken up by one word. You work it out by dividing the number of times the word appears by the total word count and multiplying by 100. Kwebby's tool divides by the total word count of the text you paste.
What is a good keyword density?
No official number exists. Google's spam policy and SEO Starter Guide describe the problem as unnatural repetition and give no percentage. Kwebby's tool flags a word as Over above 5 percent and Low below 0.5 percent, which are quick signals for your own review.
What is keyword stuffing?
Keyword stuffing is filling a page with keywords or numbers to manipulate search rankings. Google lists it in its spam policies. Signs include the same phrase in every paragraph, sentences that exist only to carry a keyword, and lists of terms with no value to a reader.
Does the Kwebby Keyword Density Checker analyze a URL or phrases?
No URL. You paste text into the Content box. The table lists single words only, but the Target Keyword box counts a phrase. To check a published page, copy its body text and paste it in.
Why does my target keyword show zero?
The Target Keyword box matches whole words in the same order, so a plural or a different spelling does not match. Check the exact form you used in the text. The minimum word length slider does not affect the target keyword.
Is the Kwebby Keyword Density Checker free?
Yes. The tool is free and needs no account.
Final Thoughts
Paste your next draft into the Keyword Density Checker and read the top five rows before you publish. Fix the words that repeat for no reason, keep the ones that carry your topic, and ignore any number that makes the sentence worse. Run the revised text through the Readability Checker to confirm it still flows. Good copy earns its keywords by saying useful things about them.
