Search Engine Optimization (SEO) is the practice of enhancing a website's visibility on search engines like Google and Bing. By optimizing various elements such as content, keywords, and site structure, businesses aim to rank higher in search results, attracting more organic traffic. Effective SEO involves both on-page and off-page strategies. On-page SEO focuses on optimizing individual pages, while off-page SEO involves building backlinks and improving site authority. Together, these strategies help improve a website's ranking, ultimately leading to increased visibility and potential customer engagement.
