How it works
How to use the keyword density checker
- Paste your content. Use the full page text — an article, service page, or product description. The more complete the text, the more accurate the percentages.
- Enter your focus keyword (optional). This is the main phrase you want the page to rank for, like "airport car service" or "keyword density checker."
- Click Analyze Content. You'll see total and unique word counts, your focus keyword density with a verdict, and the most-used single words, two-word phrases, and three-word phrases.
- Act on the verdict. If the keyword is underused, add it to your title, opening paragraph, and one heading. If it's too high, swap some repeats for natural variations and related terms.
How keyword density is calculated
Example: a 1,000-word article that uses "car service" 12 times has a keyword density of 12 ÷ 1,000 × 100 = 1.2%.
This tool counts each full match of your focus phrase as one use and divides by the total word count of the page. Some tools multiply multi-word phrases by the number of words in the phrase, which produces higher percentages — so numbers can differ slightly between tools. What matters is the trend, not the exact decimal.
Where your keyword density should land
How to read your results
| Focus keyword density | What it usually means |
|---|---|
| Below 0.5% | Underused. Google may not be sure what the page is mainly about. |
| 0.5% – 2.5% | Healthy. Clear topic signal while still reading naturally. |
| 2.5% – 3.5% | On the high side. Replace some repeats with synonyms and related terms. |
| Above 3.5% | Likely reads as keyword stuffing. Rewrite for readers first. |
These ranges are practical guidelines, not rules published by Google. Use them to spot problems, then read the page out loud — if a phrase sounds forced, it probably is.
Using the phrase lists
The two- and three-word phrase lists show what your page is actually about in the eyes of a reader. If your top phrases don't match your focus keyword, the page may be drifting off-topic. If a phrase you care about is missing entirely, that's a content gap worth filling.
Does keyword density still matter?
Google has said keyword density is not a direct ranking factor. Modern search understands synonyms, related concepts, and search intent, so repeating one exact phrase doesn't help you rank.
It's still a useful diagnostic. Very low density can mean the page never clearly states its topic. Very high density can look like keyword stuffing, which Google's spam policies specifically warn against. A density check takes seconds and catches both problems before you publish.
Common keyword density mistakes
- Forcing the exact phrase everywhere. Use natural variations — "car service," "car service to the airport," "private driver."
- Missing the keyword in key spots. Your title, first paragraph, and at least one heading matter more than the total count.
- Checking only part of the page. Paste the whole visible text so percentages reflect what Google sees.
- Optimizing for a number instead of the reader. A page that fully answers the searcher's question beats one with a "perfect" percentage.
Frequently asked questions
What is a good keyword density?
Most SEO practitioners aim for roughly 0.5% to 2.5% for the main keyword. There is no official ideal number. Write naturally, use the keyword in your title, first paragraph, and a heading, and cover the topic with related terms.
How is keyword density calculated?
Keyword density = (number of times the keyword appears ÷ total words on the page) × 100. A keyword used 12 times in a 1,000-word article has a density of 1.2%.
Is keyword density a Google ranking factor?
Google has said it does not use keyword density as a direct ranking factor. It is still useful as a diagnostic: very low density can mean the page never clearly states its topic, and very high density can look like keyword stuffing, which Google's spam policies warn against.
What is keyword stuffing?
Keyword stuffing is repeating a keyword unnaturally to try to manipulate rankings, such as forcing the exact phrase into every sentence or listing keywords in blocks. It makes content harder to read and can hurt rankings.
