About Keyword Density

Keyword density is a foundational concept in SEO that measures how frequently a specific keyword appears in your content relative to the total word count. It's expressed as a percentage.

Why is keyword density important? While modern search algorithms consider many factors, keyword density remains a valuable metric for:

Optimal keyword density: Most SEO experts recommend keeping your primary keyword density between 0.5% and 2.5%. Higher densities may be perceived as keyword stuffing, while lower densities may not adequately signal relevance to search engines.

Frequently Asked Questions

What is a good keyword density percentage?
A good target is typically between 0.5% and 2.5% for your primary keyword. Secondary keywords should have lower density. This varies slightly by industry and competition level.
Should I count stop words in keyword density?
No, stop words (common words like "the", "and", "is") are typically excluded from keyword density calculations because they don't carry significant meaning. Our tool excludes them by default.
Can keyword density be too high?
Yes, keyword stuffing (excessive repetition) can lead to search engine penalties. If your main keyword density exceeds 3%, consider revising your content to sound more natural.
How does this tool calculate keyword density?
We calculate keyword density as: (Number of times keyword appears / Total word count) × 100. Our algorithm ignores HTML tags, punctuation, and common stop words for accurate results.
Does keyword density affect SEO rankings?
While not the primary ranking factor, keyword density helps search engines understand content relevance. However, content quality, user experience, and backlinks are more important ranking factors.
