FAQ
What is keyword density?
Keyword density = (number of times a keyword appears ÷ total word count) × 100. A 500-word article mentioning 'SEO' 5 times has a 1% keyword density for that term.
What is the ideal keyword density?
There is no universally ideal percentage. Google's algorithms understand context, not just frequency. 1–2% is a rough natural-sounding range. Focus on writing naturally for humans, not hitting a density target.
What is keyword stuffing?
Keyword stuffing is unnaturally repeating a keyword to manipulate rankings. Google penalizes this. Signs: density above 3–4%, awkward phrasing, repetition in image alt text, and hidden text.
