A plain-language explanation
Keyword density is the percentage of the selected word or phrase in the entire content of the page.
Where it helps in practice
Keyword density is a simple ratio that cannot judge answer quality or natural language.
The decision before implementation
Avoid a target percentage; cover the subject properly, use precise terminology and edit for a defined reader.
A trap worth avoiding
Keyword density should not be implemented or judged apart from the user task. Mechanical application may improve one metric while making clarity, control or ongoing support worse.
How to verify the result
Read the copy aloud and review repetition, question coverage and post-publication user behaviour.
A business takeaway
Good use of Keyword density begins with a named problem, owner and expected outcome. At PAR HOUSE Agency we record the baseline, implement within a controlled scope and only then assess the effect.
