Keyword density is one of the oldest SEO concepts — and still one of the most misunderstood. Used well, it's a sanity check. Used badly, it's a fast way to over-optimize.
What is keyword density?
Keyword density is the percentage of times a keyword appears in your text relative to the total word count. A 1,000-word post that mentions 'readability' 15 times has a 1.5% density for that term.
What are healthy density ranges?
Most modern SEO guides recommend 1–2% for the primary keyword. Below that, search engines may struggle to confirm the topic. Above ~3%, text starts to look stuffed.
Avoiding keyword stuffing
Stuffing is what happens when keyword density becomes the priority over clarity. Synonyms, related entities and a clean structure all help you cover a topic without repeating the same phrase — pairing a density check with a full SEO writing pass keeps the balance right.
