Density Guide
What is Keyword Density?
Keyword density is the percentage of times a keyword or phrase appears on a page compared to the total number of words. It's a fundamental SEO metric that helps search engines understand what your content is about.
While keyword density was once a primary ranking factor, modern SEO focuses more on natural language and user intent. However, maintaining appropriate keyword density still helps ensure your content is relevant and optimized.
Formula:
Keyword Density = (Keyword Count / Total Words) x 100Why Keyword Density Matters for SEO

- "marketing" - broad topic indicator
- "SEO" - industry-specific term
2+Phrase Keywords (N-grams)

Frequently Asked Questions
What is the ideal keyword density for SEO?
The ideal keyword density is generally between 1-2.5%. This range is enough to signal relevance to search engines without appearing spammy. However, focus on natural writing first - if your keyword fits naturally at 1.5%, that's better than forcing it to 2.5%.
Can keyword density affect my Google rankings?
Yes, but not in the way it used to. Google's algorithms have evolved beyond simple keyword counting. While appropriate keyword usage is still important, over-optimization (keyword stuffing) can hurt rankings. Focus on user intent and natural language rather than hitting a specific percentage.
What is keyword stuffing?
Keyword stuffing is the practice of overusing keywords to manipulate search rankings. This includes repeating keywords unnaturally, using hidden text, or placing keywords where they don't make sense. Search engines can detect this and may penalize your site.
How do I reduce keyword density?
Use synonyms and related terms instead of repeating the exact keyword. Expand your content with valuable information that naturally dilutes keyword frequency. Also, consider using longer content - the same keyword count spread over more words reduces density.
Should I check keyword density for every page?
For important pages targeting specific keywords, yes. Focus on key landing pages, product pages, and cornerstone content. For general blog posts, write naturally and only check if you suspect over-optimization or if the page isn't ranking as expected.
