Does keyword density still matter for SEO?

While keyword density is less important than it once was, it still matters. Modern SEO focuses more on natural language and semantic relevance, but maintaining reasonable keyword density helps search engines understand your content's topic.

How do I check keyword density?

Paste your content into our keyword density checker tool. It will analyze your text and show you the frequency and density percentage of each word and phrase, helping you optimize your content for SEO.

Should I analyze single words or phrases?

Both are important. Single keywords (1-word) show individual word usage, while 2-word and 3-word phrases help you understand how well you're targeting long-tail keywords and natural language patterns.

What is Keyword Density?

Keyword density measures how often a keyword or phrase appears in your content relative to the total word count. It's calculated as: (Number of keyword occurrences / Total words) × 100%

For example, if "SEO tools" appears 5 times in a 500-word article, the keyword density is 1%.

Optimal Keyword Density

Most SEO experts recommend maintaining a keyword density between 1-2%. This range is considered natural and unlikely to trigger keyword stuffing penalties.

0.5-1%: Light usage, may need more focus
1-2%: Optimal range for most content
2-3%: High density, use with caution
3%+: Risk of keyword stuffing

Why It Matters

While modern SEO algorithms are sophisticated and focus on semantic relevance, keyword density still plays a role in helping search engines understand your content's topic and relevance.

Proper keyword usage helps with:

Topic relevance signals
Natural content flow
