Keyword Density Checker
Check keyword density online — paste your text to see the top 1, 2 and 3-word phrases with counts and percentages, plus over-optimization warnings.
About the Keyword Density Checker
This free keyword density checker analyses any text and shows exactly which words and phrases dominate it. Paste your article, product page or blog post and you instantly get the total word count plus three tables: the top single keywords, the top 2-word phrases and the top 3-word phrases — each with its count and density percentage.
Common stopwords such as "the", "and" and "with" are filtered out of the single-word results, so the table reflects the topics your content is genuinely about rather than grammatical glue. Multi-word phrase tables keep every word, because phrases like "best running shoes" are exactly what you want to see.
Any phrase above 3% density is highlighted as a possible over-optimization risk. SEO writers use this to confirm a page targets its intended keyword naturally, spot accidental repetition, and compare their density against top-ranking competitor pages. All analysis happens in your browser — nothing is uploaded.

- 2Check the total word count and the three phrase tables that appear instantly.

Frequently Asked Questions
What is a good keyword density for SEO?
Most SEO professionals aim for roughly 0.5% to 2% for a primary keyword — enough that the topic is unmistakable, not so much that it reads as stuffing. There is no official Google number; modern ranking is semantic. Treat density as a sanity check: if one phrase exceeds 3%, the text usually sounds repetitive to human readers too, and that is the real problem.
How is keyword density calculated?
Density is the number of times a word or phrase appears divided by the total number of words (or possible phrases of that length), multiplied by 100. If "coffee grinder" appears 8 times in a 400-word article, its 2-word density is about 2%. This tool computes it separately for single words, 2-word and 3-word phrases so you can see focus at every level.
Why are words like "the" and "and" missing from the results?
The single-keyword table excludes stopwords — extremely common words such as "the", "and", "with" and "from" that appear in every text regardless of topic. Including them would bury your actual keywords under grammatical noise. The 2-word and 3-word phrase tables keep stopwords, because phrases like "how to bake" are meaningful search queries.
Does keyword stuffing hurt my rankings?
Yes. Google's spam policies explicitly list keyword stuffing — unnaturally repeating words or phrases to manipulate rankings — as a violation that can demote or remove pages. Beyond penalties, stuffed text converts poorly because it reads badly. If this tool highlights a phrase above 3%, rewrite some occurrences with synonyms and natural variations.
Can I check a competitor's keyword density?
Yes — open the competing page, select and copy its visible text, and paste it here. You will see which 1, 2 and 3-word phrases the page emphasises and at what density. Comparing the top-ranking pages for your target query is a quick way to understand the vocabulary and subtopics Google associates with that search intent.
