Frequently Asked Questions

What is keyword density?

Keyword density is the percentage of times a keyword appears in a piece of text relative to the total word count. For example, if a 500-word page contains your target keyword 10 times, the density is 2%.

What is a good keyword density for SEO?

Most SEO experts recommend keeping keyword density between 1–3%. Going above 3–4% may be flagged as keyword stuffing by search engines, which can hurt your rankings. Focus on natural, reader-first writing.

What is keyword stuffing?

Keyword stuffing means overusing a keyword unnaturally to try to rank higher. Modern search engines like Google use semantic analysis and can penalize pages that stuff keywords. A density above ~4% for a specific keyword is usually a warning sign.

How do I improve my keyword density without stuffing?

Use related keywords (LSI keywords), synonyms, and natural language. Write for your readers first. Tools like SwiftCopy's SEO Article Writer can help you write balanced, SEO-friendly content automatically.
