When discussing keyword occurrence in the context of search engine optimization (SEO), we’re referring to the number of times a specific term appears within the content of a web page. This frequency is scrutinized by algorithms, particularly Google’s, as it’s a key indicator of the page’s topic. In theory, the more frequently a keyword appears, the better the page’s chances of ranking highly in search results for that keyword. However, caution is advised, as deliberate keyword overuse can lead to SEO over-optimization, which is not recommended. Originally, keyword occurrence was calculated for both search engines and users. Today, the focus is primarily on the page’s visible content, although the presence of the keyword in tags like “alt” attributes can still play a significant role. Keyword occurrence therefore remains a crucial element of any organic search engine optimization strategy.
