Density = (Keyword Count / Total Words) x 100
Keyword density is calculated by dividing the number of times a keyword appears by the total word count, then multiplying by 100 to get a percentage. Aim for 1-3% for primary keywords.
Frequently Asked Questions
Keyword density is the percentage of times a keyword appears in your content compared to the total word count. It matters for SEO because search engines use it to understand what your content is about. However, overusing keywords (keyword stuffing) can hurt rankings, while too low density means search engines may not recognize your topic focus.
The ideal keyword density is generally between 1-3% for your primary keyword. This means your main keyword should appear 1-3 times per 100 words. For secondary keywords, aim for 0.5-1%. Modern SEO focuses more on natural language and semantic relevance rather than exact percentages, but staying within this range helps avoid over-optimization penalties.
Keyword stuffing is the practice of overusing keywords unnaturally to manipulate search rankings. Signs include: keyword density above 3-4%, awkward repeated phrases, hidden text, and irrelevant keywords. Google penalizes keyword stuffing with lower rankings or removal from search results. Focus on writing naturally for users, not search engines.
Stop words (the, a, an, is, are, etc.) are typically excluded from keyword analysis because they add no SEO value. Our tool automatically filters common stop words to give you meaningful results. However, for long-tail keyword phrases like "how to bake a cake," the full phrase including stop words should be analyzed together.
2-word (bigrams) and 3-word (trigrams) phrases are multi-word keyword combinations that often carry more specific meaning than single words. For example, "content marketing" is more specific than just "content." These longer phrases often have less competition and higher conversion rates because they match more specific search intent.
Check keyword density during content creation and before publishing. Review it when updating old content for SEO improvements. However, do not obsess over exact numbers - focus on creating valuable, readable content. Use the tool as a guide to ensure balanced keyword usage, not as a strict formula to follow.
