Keyword density shows how often a word or phrase appears in your content. It is not a ranking formula, but it helps you spot pages that are under- or over-optimised and keep your copy natural.
What keyword density means
Density is the frequency of a keyword divided by the total word count, usually shown as a percentage. It is most useful as a qualitative signal rather than a strict target.
- High density may look spammy to readers and search engines.
- Low density can mean your page is not focused on the topic.
- Single-word, two-word and three-word phrases tell different stories.
- Stop words should generally be ignored when analysing keyword density.
Checking keyword density in your text
Paste your page copy into the Keyword Density Checker to see the most common terms, phrase frequency, and density percentages. Use it to refine headings, improve readability, and confirm your content stays on topic.
Avoid over-optimisation
- Do not repeat the same exact phrase unnaturally.
- Use synonyms and supporting terms to broaden relevance.
- Write for people first and search engines second.
- Keep content useful and easy to read.
ToolOrbit’s Keyword Density Checker helps you balance your content so it is both optimised and natural.
Read density as a symptom, not a score
A 1,000-word page that repeats “best CRM software” twelve times has hit an inflated density without gaining any relevance worth having. A page that never states its exact phrase may be perfectly on-topic through synonyms and context. Density reports are useful only for flagging outliers: a term that appears in nearly every paragraph, or an important phrase that never appears at all in the copy you just wrote.
Building a natural on-topic pattern
- State the primary keyword once in the title and once early in the body.
- Repeat it only where it is the genuine subject of the sentence.
- Weave in synonyms and related terms — they are how topical relevance reads as knowledge.
- Let headings express tasks and benefits rather than repeating the exact phrase.
Phrases tell a truer story than single words
The interesting readings come from n-grams longer than one word: “best CRM software” occurs far less often than “software” alone, yet it is the phrase users type. A density checker that reports one-, two- and three-word matches lets you confirm the exact concept appears naturally without chasing an inflated single-word ratio. When the three-word phrase shows zero but the topic is covered through synonyms, write the exact phrase once — that is the fix, not keyword-stuffing everywhere.
- Pass one: check phrases; a clean three-word coverage beats a spammy single-word score.
- Pass two: confirm the phrase appears in the title or the first paragraph.
- Pass three: read for fluency — density is a diagnostic, not a target.
