Keyword Density Best Practices
What is keyword density?
Keyword density is the percentage of times a keyword appears compared to the total word count. If "AI chatbot" appears 5 times in a 500-word article, the density is 1%. Google doesn't use an exact threshold, but patterns matter.
The sweet spot: 0.5%–2.5%
Most SEO professionals target 0.5%–2.5% for primary keywords. Below 0.5% and Google may not associate your page with that keyword. Above 3% and you risk over-optimization penalties. Natural writing usually lands in the right range.
N-grams matter more than single words
Google understands phrases, not just individual words. A 2-word phrase like "voice agent" carries more semantic weight than either word alone. Check your 2-word and 3-word tabs to see which phrases dominate your content.
Use synonyms and LSI keywords
Instead of repeating the same keyword, use related terms. For "AI chatbot," also use "conversational AI," "chat assistant," "automated support." This signals topical depth to Google without triggering keyword stuffing filters.
