Keywords play a crucial role in website ranking, which is how high a website appears in search engine results pages (SERPs). The relationship between keywords and website ranking involves several key aspects: 1. Relevance: Keywords must be relevant to the content on the webpage. Search engines analyze the relevance of keywords in the context of the entire page to determine if the page should rank for those terms. 2. Keyword Placement: Strategic placement of keywords in important areas of the webpage, such as the title tag, headings, meta descriptions, URL, and throughout the body content, helps search engines understand the main topics of the page.
