How keyword density is calculated
Keyword density is the share of a text taken up by one keyword: the number of times it appears, multiplied by the number of words in it, divided by the total word count. A two-word phrase used 5 times in a 1,000-word article has a density of 5 × 2 ÷ 1,000 = 1%.
This checker counts whole words, ignores case and punctuation, and treats every language's letters as word characters, so accented and non-Latin text is counted correctly.
Is there an ideal keyword density?
No. Google has never used a target density, and modern ranking is based on how well a page covers a topic, not how often it repeats a phrase. Treat density as a check, not a goal.
In practice, a page about a topic naturally uses its main phrase somewhere around 0.5–2% of the time. If yours is far below that, the page may not clearly say what it's about. If it's well above 3% — or the top of the list is one phrase repeated in every paragraph — read the text aloud. Repetition that sounds forced to a reader is what Google's spam policies call keyword stuffing.
Use phrases, not just single words
Single words are rarely what people search for. The 2- and 3-word views show the phrases your text actually repeats, which tells you more about what a search engine will think the page covers. If the top phrases aren't the ones you're targeting, the page is probably about something slightly different from what you intended.
What to do with the results
A quick review usually comes down to a few checks:
- Your target phrase appears in the title, the main heading and the first paragraph.
- Related terms and synonyms appear too — these show topic coverage better than repeating one phrase.
- No single phrase dominates the list unless it's genuinely the subject of every paragraph.
- Words you didn't mean to emphasise aren't near the top.
