Keyword density is a simple ratio: how often a word or phrase appears compared with the total number of words in a piece of text. It can help you notice repetition, but it is not a score that guarantees search rankings.
The basic formula
Keyword density (%) = exact phrase occurrences ÷ total words × 100.
Example: if a 800-word draft contains the exact phrase “keyword density” four times, the simple phrase density is 4 ÷ 800 × 100 = 0.5%. The result depends on what text you count, how your tool treats punctuation and whether it counts exact phrases or separate words. Use the same counting method when comparing drafts.
Is there an ideal keyword density?
Google does not publish a target percentage for keyword density. A fixed “ideal range” can encourage awkward repetition and does not account for synonyms, context, search intent or the different ways people phrase a question. Google’s guidance focuses on useful, reliable, people-first content, and its spam policies identify unnatural repetition used to manipulate rankings as keyword stuffing. Read Google’s keyword-stuffing policy and helpful-content guidance.
Use frequency as an editing check
- Write the page to answer the reader’s question first.
- Use the Word Counter to inspect total words and repeated terms.
- Read the draft aloud. Replace repetitions that sound unnatural; keep words that are necessary for clarity.
- Check that the title, headings and opening accurately describe the page—do not force an exact phrase into every section.
Frequency reports are useful for spotting accidental repetition, especially in short copy. They cannot judge whether a page is relevant, original, accurate or helpful. Treat the number as a proofreading signal, not a ranking instruction.
Frequently asked questions
Does repeating a keyword improve rankings?
Repeating a term beyond what the reader needs is not a reliable optimization method. Explain the subject clearly and use natural wording.
What is keyword stuffing?
It is unnatural repetition or lists of terms used to manipulate search visibility. It makes a page harder to read and can violate Google Search spam policies.
Can a density checker understand search intent?
No. It counts text according to its own rules. It cannot infer what a searcher needs or whether your page provides a strong answer.
