What is keyword density?
Keyword density is the percentage of words in a text that are a particular keyword or phrase:
Keyword density = (number of times the keyword appears ÷ total words) × 100
For example, if “green tea” appears 6 times in a 600-word article, its density is 1%.
Is there an ideal keyword density?
No. Google has said for years that there is no ideal percentage, and modern search engines understand topics, synonyms and context rather than counting words. Still, density is a useful sanity check:
- 0%: your main keyword is missing, so search engines and readers may not see what the page is about.
- Roughly 0.5–2%: typical of naturally written content about a topic.
- Above 3%: often a sign of repetition that reads unnaturally and may look like keyword stuffing.
Better than density: topical coverage
Use the 2- and 3-word phrase views to check that your content covers the topic in depth. A good article about “green tea” will naturally mention phrases like “caffeine content”, “brewing temperature” or “health benefits”. If important related phrases are missing, add a section about them; that helps readers and rankings more than repeating the main keyword.
