Keyword Density Mistakes: 9 Easy Fixes That Really Work
Text and ContentYou pasted a draft into a checker and it says 6.5 percent. Or 0.2 percent. Now you wonder whether the page is broken. Most of the time the keyword density number is fine and the way it was read, counted or chased is the real problem, so this guide walks through nine mistakes and the exact fix for each.
How keyword density is calculated, and why numbers disagree
The formula is short: density = (times the term appears ÷ total words) × 100. Two tools can still give you different answers for the same page, because each one decides differently what counts as a word and what counts as a match. That gap causes most of the panic.
| Counting choice | Occurrences | Total words | Density |
|---|---|---|---|
| Phrase counted once per match | 6 | 800 | 0.75% |
| Phrase counted by words used (2 words each) | 12 | 800 | 1.50% |
| Numbers removed from the word count (40 numbers) | 6 | 760 | 0.79% |
| Menus and footer pasted in (200 extra words) | 6 | 1000 | 0.60% |
None of those rows is wrong. They answer slightly different questions. What matters is that you use one method every time, so a draft today and a draft next month are comparable. The checker on this site divides phrase matches by the total word count and ignores numbers, which is the first row with the third row adjustment.
Mistake 1: treating a magic percentage as a rule
Plenty of articles quote a perfect keyword density of 1 or 2 percent. No search engine documents such a number. Google describes keyword stuffing as filling a page with keywords or numbers to manipulate rankings, and it names repeated words that sound unnatural as the problem. It gives no ceiling.
The bands in the checker are labels based on common practice: under 0.5 percent is too low, 0.5 to 1.5 is optimal, 1.5 to 2.5 is acceptable and above 2.5 is flagged as stuffing. Use them as a prompt to reread the text, nothing more.
| Article length | 0.5% (low edge) | 1.5% (top of optimal) | 2.5% (stuffing flag) |
|---|---|---|---|
| 500 words | 2 to 3 uses | 7 to 8 uses | 12 to 13 uses |
| 800 words | 4 uses | 12 uses | 20 uses |
| 1,000 words | 5 uses | 15 uses | 25 uses |
| 1,500 words | 7 to 8 uses | 22 to 23 uses | 37 to 38 uses |
| 2,000 words | 10 uses | 30 uses | 50 uses |
Write the page for the reader first, then run the check. If the number lands outside a band but the text reads naturally, leave it alone. If it reads badly at 1.2 percent, change it anyway.
Mistake 2: counting the wrong text
Paste a whole web page and your total includes navigation, cookie notices, author boxes and footer links. That inflates the denominator and drags the percentage down. Paste raw HTML and tag names become words. Both distort keyword density in ways you cannot see.
- Symptom: the density looks too low, yet the keyword clearly shows up in every section.
- Cause: extra text, such as a 200 word footer, added to the total.
- Fix: copy only the body copy, from the first paragraph to the last, plus the headings you want counted.
- Check: the word total in the checker should be within a few words of what your editor reports. If you want a second opinion, run the same text through the Word Counter.
Mistake 3: comparing phrase and single word numbers
A one word keyword and a three word phrase are not on the same scale. The word seo can appear 6 times in a 92 word paragraph, which is 6.5 percent. A three word phrase can rarely reach that level, because each use takes up three of the words in your count.
So a phrase at 1 percent is already heavy. At 800 words it means 8 exact matches, or 24 of your 800 words, three percent of the page, spent on a single phrase. Judge phrases by how often they read in a row, not by comparing them against a single word target.
Use the two word and three word tables under the headline number. They show which phrases your draft repeats without you meaning to, such as the same bigram appearing nine times.
Mistake 4: forgetting that the match is exact
For a single word, the checker uses strict equality. The word tool matches tool and not tools. For a phrase, it matches the whole phrase with word boundaries, so a phrase never counts as a match inside a longer word. That precision is useful, and it also hides plurals and word forms.
| Keyword typed | Matches found | Density | What it tells you |
|---|---|---|---|
| tool | 4 | 0.4% | Singular only |
| tools | 11 | 1.1% | Plural only |
| tool plus tools | 15 | 1.5% | Real overall use of the idea |
| free tool | 3 | 0.3% | Exact phrase, rarely repeated |
If the singular reads 0.4 percent and the plural 1.1 percent, the draft is not under used. Add the forms together before you decide to add more. Then check the sentence list the tool prints, which shows the first five sentences that contain the keyword, so you can see whether the uses are spread out.
Mistake 5: stuffing to reach a target
This is the classic error. A writer sees 0.3 percent, adds the phrase to every other sentence and lands at 4 percent. Readers notice at once. Here is a real before and after, with the numbers worked out.
Before, keyword density 13.3 percent: 45 words, 6 uses
Cheap running shoes are what we sell. Our cheap running shoes start at 60 dollars, and every pair of cheap running shoes ships free. If you need cheap running shoes for a marathon, cheap running shoes from our store are the best cheap running shoes online.After, keyword density 2.4 percent: 42 words, 1 use of running shoes
Looking for running shoes on a budget? Our range starts at 60 dollars, and every pair ships free. Training for a marathon takes a lot of miles, so pick a cushioned pair that suits your stride. Budget does not have to mean cheap.The rewrite keeps the meaning and removes five repeats. On a short sample like this the percentage looks high because there are so few words, which is why you should check whole pages, not snippets. A single paragraph says very little about the page.
Replace exact repeats with a pronoun, a synonym or a more specific phrase, such as cushioned trainers or road shoes. Keep the exact phrase for the title, the first paragraph and one heading.
9 divided by 1,000 is 0.009, and times 100 gives 0.9 percent. That sits in the optimal band the checker labels 0.5 to 1.5 percent.
Mistake 6: ignoring where the keyword appears
Two pages with the same keyword density can read very differently. One places the term in the first paragraph, a heading and the conclusion. The other buries all 12 uses in a single middle section. The percentage is identical and the second page feels odd.
Use the sentence lookup and the highlighted view in the checker. Highlighted matches that clump together are a quick visual warning. A good spread has a use near the start, one or two in subheadings and a few naturally placed through the body.
Mistake 7: reading the stopword table as insight
Turn on the include stopwords option and the single word table fills with the, and, of and to. Those words can reach 4 or 5 percent each and mean nothing. By default the checker removes about ninety common function words from the word and phrase tables, and the phrase tables also skip words of two letters or fewer.
There is one good use for the toggle. If a draft feels padded, switch stopwords on and look for filler such as very, really and just. A word like that at 1.5 percent is a style problem you can edit out in five minutes.
Mistake 8: chasing a number instead of intent
Matching the number on a top ranking page tells you what that page did, not why it ranks. Pages win on usefulness, links, clarity and fit with the query. Copying a competitor figure of 1.3 percent will not copy any of that.
Number driven editing
- Starts from a target percentage
- Adds the phrase until the bar turns green
- Produces repeats and awkward sentences
- Rarely adds new information
Reader driven editing
- Starts from the question the page answers
- Adds missing facts, examples and numbers
- Uses the density check as a final read
- Keeps the exact phrase in key places only
Mistake 9: running the check once and stopping
Edits change the total word count. Cut 300 words from a 1,300 word draft and every percentage moves, even if you never touched the keyword. A phrase at 0.8 percent before the trim sits at 1.0 percent after it.
Quick keyword density reference: symptom, cause and fix
| Symptom | Likely cause | Fix |
|---|---|---|
| Density far lower than expected | Menus or footer pasted in | Paste body copy only |
| Density far higher than expected | Short sample, or numbers removed from the total | Test the full page, not a paragraph |
| Keyword shows 0 matches | Plural or other word form used | Check each form, then add them up |
| Stuffing warning above 2.5% | Exact repeats in many sentences | Swap in synonyms and pronouns |
| Two tools disagree | Different counting rules | Pick one method and keep it |
| Top word table is all small words | Stopwords included | Turn the toggle off |
If your text is also hard to read, run it through the Readability Scorer. Short sentences usually fix repetition and reading level in the same pass.

Open the Keyword Density CheckerFrequently asked questions
What is a good keyword density?
There is no official figure. Many writers aim for roughly 0.5 to 1.5 percent for a focus phrase and treat anything above 2.5 percent as a prompt to edit. Natural reading matters more than the number.
How do I calculate keyword density by hand?
Count how many times the phrase appears, divide by the total number of words, then multiply by 100. For example, 9 uses in 1,200 words is 0.75 percent.
Does Google use keyword density as a ranking factor?
Google does not publish a keyword density target. Its spam policies warn against keyword stuffing, meaning repetition that manipulates rankings and reads unnaturally.
Why does my keyword density checker show zero?
Most often the exact word or phrase is not in the text. The match is exact, so a plural or a different word order will not count. Try each form separately.
How many times should I use my keyword in 1,000 words?
Between 5 and 15 uses of an exact phrase is a typical range, which equals 0.5 to 1.5 percent. Fewer is fine when the page uses synonyms and clearly covers the topic.
Is keyword density the same as keyword frequency?
No. Frequency is the raw count of uses. Density turns that count into a percentage of total words, which lets you compare pages of different lengths.
