Keyword density is the percentage of times a keyword or phrase appears in a web page compared to the total number of words on the page. In other words, it is a measure of how often a keyword appears in a web page in relation to the total number of words on that page.
In the early days of search engine optimization (SEO), keyword density was considered an important factor in determining a web page’s relevance and ranking in search engine results pages (SERPs). However, with the evolution of search algorithms and the increasing focus on user experience and quality content, the relevance of keyword density has declined in recent years.
Today, keyword density is not as important a factor in SEO as it once was, and having a high keyword density can actually harm a web page’s ranking in search engine results pages (SERPs) by making the content appear spammy and keyword-stuffed. Instead, search engines now place a greater emphasis on quality, relevance, and user experience, and high-quality content that is written for humans, not just search engines, is more likely to rank well in search results.
It’s important to note that the ideal keyword density varies depending on the keyword and the content on the page, but as a general rule, a keyword density of 1-2% is considered a safe and effective range for SEO.
