For years, SEO advice fixated on keyword density — the percentage of a page's words that matched the target keyword, with a "sweet spot" somewhere between 1% and 3%. That number was never really a ranking factor, and today it matters even less. But the underlying question — how often should you actually mention your keyword? — still has a real answer.
Why the Old Advice Broke Down
Search engines stopped counting keyword occurrences and started evaluating whether a page actually satisfies the search intent behind a query. A page can mention its target phrase once and rank well if it's genuinely the best answer available, or mention it fifty times and rank nowhere because it reads like it was written for a crawler instead of a person.
A well-optimized page today should:
- Use the target phrase where it's natural: title, intro, at least one subheading
- Use variations and related terms throughout, not the same exact phrase
- Read fluently when read aloud — no phrase should feel repeated for its own sake
- Prioritize covering the topic fully over hitting any percentage target
A Simple Framework
- Write the page for the reader first, without counting anything
- Confirm the primary keyword appears in the title, intro, and one heading
- Scan for unnatural repetition and vary the phrasing where it reads oddly
- Ignore density percentage entirely — it was never the actual signal
> Tip: If you have to check a density calculator to know whether your keyword usage looks natural, it probably isn't. Read the page out loud instead.
Example
Before: "Our french press coffee guide covers french press coffee brewing so you can master french press coffee at home."
After: "This guide covers everything you need to brew a great cup with a French press, from grind size to steep time."
Common Mistakes
- Optimizing for a density percentage instead of readability
- Repeating the exact keyword phrase when a natural variation reads better
- Under-using the keyword out of fear of "over-optimization" penalties that don't apply to normal writing
- Skipping related terms that would make the page more topically complete
If you want a sanity check on how a page's terms compare to natural usage, SeoWolf's Keyword Density Checker is useful — just treat the number as a diagnostic, not a target.
Keyword density was always a proxy for something else: does this page actually sound like it's about what it claims to be about? Write for that, and the percentage takes care of itself.
