# Free Keyword Density Checker

Optimize your content for SEO with our free keyword density checker. Analyze how often your target keyword appears and ensure you're not over or under-optimizing.

Free, no sign-up. The tool itself runs on the HTML page — this representation carries everything around it.

## How Keyword Density Is Calculated, and What the Number Means

Keyword density is how often a keyword or phrase appears in a text, as a share of all its words: density = keyword occurrences ÷ total words × 100. Type the keyword, paste your text, and this checker shows the number of matches, the total word count, the sentence count and the density to two decimal places, updating as you type.

How words are counted. Total words means every space-separated item in the text, numbers included, so the keyword's own words count toward the total. Matching ignores capitals. A one-word keyword matches whole words only, and punctuation stuck to a word doesn't get in the way: "SEO," and "(SEO)" both count for SEO, but "SEOs", "SEO's" and "SEO-friendly" do not. Characters other than the letters a–z and digits are ignored when comparing, so the checker is built for English text.

How phrases are counted. A keyword of two or more words must appear as that exact phrase, in that order, as whole words. Each occurrence counts once against the total word count, so a three-word phrase used 9 times in 1,200 words has a density of 0.75%. Plurals, reordered words and phrases split across a line break are not counted. Some checkers multiply by the number of words in the phrase instead, which would report the same text at 2.25%. Neither is wrong, but it is why two keyword density checker tools can disagree by a factor of three on the same page.

Reading the result. 0% shows Keyword not found. Below 0.5% is labeled Too Low, 0.5–2.5% Optimal, and above 2.5% Too High. Those bands are a writer's rule of thumb, not a Google number: they are a prompt to re-read, not a target to hit. A text at 3% that reads naturally is fine, and a text at 1.5% where every mention is forced is not.

Why there is no Google threshold. Google publishes no ideal density. Its spam policies define [keyword stuffing](https://skribra.com/glossary/keyword-stuffing) as filling a page with keywords or numbers in an attempt to manipulate rankings, with examples such as repeating the same words or phrases so often that it sounds unnatural. Its SEO Starter Guide adds that excessively repeating the same words, even in variations, is tiring for users. Both describe how text reads, not a percentage, which is why this tool's labels are worded as cues rather than verdicts.

Common mistakes. Pasting the whole page, with navigation, footer and comments, changes the word count and the density with it; paste the body copy you wrote. Short texts exaggerate every mention: in a 150-word product description one use is already 0.67%. Exact-match counting misses the variants and synonyms readers and search engines both understand, so a low number on a long, on-topic article rarely means the keyword is missing. And density says nothing about placement. A keyword in the [title tag](https://skribra.com/glossary/title-tag), the first paragraph and one subheading tells a reader more than ten extra mentions further down.

Use it alongside the rest of the workflow: pick the phrase with the [keyword research tool](https://skribra.com/tools/keyword-research), then run the finished draft through the [word frequency counter](https://skribra.com/tools/word-frequency-counter) to see which other words you lean on without noticing.

## FAQ

### What is keyword density?

Keyword density is the percentage of a text's words taken up by a specific keyword or phrase: (keyword occurrences ÷ total words) × 100. If a keyword appears 10 times in a 1,000-word article, its density is 1%.

### How do I check keyword density?

Type your target keyword or phrase into the Target Keyword field, then paste your text into the box below it. The checker counts the matches and total words as you type and shows the density, plus whether it falls below, inside or above the common 0.5–2.5% rule of thumb. Paste only the body copy for an accurate figure.

### What is the ideal keyword density for SEO?

There isn't one. Google publishes no target percentage or density threshold; its spam policies describe keyword stuffing as repeating words so often that the text sounds unnatural, not as crossing a number. Many SEO writers use roughly 1–2% for a primary keyword as a heuristic and treat anything well above 2.5% as a cue to re-read for forced repetition.

### How does the checker count multi-word keywords?

As an exact phrase, matched as whole words and ignoring capitals. Each occurrence of the phrase counts once, and the count is divided by the total number of words in the text. Plurals, reordered words and other variants are not counted.

### Why do keyword density checker tools give different results?

They count differently. Some multiply phrase matches by the number of words in the phrase, some remove stop words such as "the" and "a" from the total, and some analyze a whole web page including navigation and footer. This checker counts each phrase once and divides by every word in the text you paste, so compare figures from the same tool.

### What is keyword stuffing?

Keyword stuffing is filling a page with keywords or numbers in an attempt to manipulate search rankings. Google's spam policies name it explicitly, with examples such as repeating the same words or phrases so often that it sounds unnatural and blocks of text listing the cities a page wants to rank for. Pages that violate those policies may rank lower or not appear in results at all.

### Does keyword density still matter?

As a diagnostic, yes; as a target, no. Using your main keyword where it naturally belongs helps readers and search engines see what the page is about, and an unusually high density is a quick way to spot repetition. Beyond that, covering the topic thoroughly matters far more than the exact percentage.

### Should I use exact match keywords?

Use the exact phrase where it reads naturally, such as the title and opening paragraph, then write normally. Google understands synonyms and related phrasing, and its SEO Starter Guide notes that varied wording gives a page more chances to show up in Search. This checker only counts exact matches, so it will under-report a text that uses natural variations.
