Editing Keyword density (section)

==Overview==
'''Keyword density''' refers to the percentage or frequency at which a specific keyword or phrase appears within a web page compared to the total word count. It is a fundamental concept in search engine optimization (SEO) that can significantly influence a website's visibility on search engine results pages (SERPs). Keyword density is often expressed as a percentage, calculated by dividing the number of times a keyword appears by the total number of words in the document. This percentage gives an indication of how often a keyword or phrase appears in relation to other words on the page. It can be used as an indicator of relevance and quality of content for a given keyword, which in turn can influence a page's ranking in search results.

While keyword density was once a major factor in ranking pages, search engines like Google have since evolved to use more sophisticated algorithms. High keyword density alone no longer guarantees high search rankings, as search engines now also look at factors like user engagement, content quality, and semantic context.
