What role does SEO play in digital marketing?

Search Engine Optimization (SEO) plays a crucial role in digital marketing by enhancing website visibility in search engines. This visibility is essential because the majority of online experiences begin with a search engine, and a higher position in search results can lead to increased traffic to a website. When a site is optimized for search engines, it improves the chances of being found by potential customers who are actively searching for relevant products or services. This process involves various techniques, including keyword optimization, improving site structure, and ensuring high-quality content, all aimed at attracting organic traffic.

While other choices relate to different aspects of marketing, they do not encompass the core function of SEO. Email marketing, customer spending habits, and social media strategies each play distinct and important roles in the broader digital marketing landscape, but they do not contribute directly to improving search engine rankings and visibility, which is the primary focus of SEO.
