Keyword density is the percentage of times a keyword appears in your content compared to the total word count. A keyword density of 1–3% is generally considered optimal for SEO — enough for search engines to understand the topic, without appearing as keyword stuffing.

Frequently Asked Questions

What is the ideal keyword density for SEO?

A density of 1–3% is considered optimal. Below 0.5% may be too low for relevance signals. Above 3–4% risks keyword stuffing penalties from Google. Focus on natural writing and semantic variation over exact density.

Should I remove stop words from keyword analysis?

Yes. Stop words like "the", "and", "is" appear very frequently and have no SEO value. Filtering them gives a more accurate picture of meaningful keyword usage in your content.
