Keyword density is the percentage of times a keyword or phrase appears on a web page compared to the total number of words on the page. It's a metric used in Search Engine Optimization (SEO) to analyze and optimize content for specific target keywords.
Synonyms: Keyword frequency, Keyword ratio, Term frequency, Keyword saturation
Keyword density is an important factor in SEO because it helps search engines understand the main topic of a web page. When used correctly, it can improve a page's relevance for specific search queries, potentially boosting its rankings in search engine results pages (SERPs).
To calculate keyword density, use this formula: (Number of times the keyword appears / Total number of words) x 100
For example, if a 1000-word article contains a specific keyword 10 times, the keyword density would be: (10 / 1000) x 100 = 1%
While there's no perfect keyword density, many SEO experts recommend aiming for a density between 1-2% for primary keywords. However, it's crucial to use keywords naturally and avoid overstuffing, which can lead to penalties from search engines.
