What role does SEO play in online content visibility?

The role of SEO, or Search Engine Optimization, in online content visibility primarily lies in its ability to enhance visibility in search engines. SEO encompasses a variety of strategies and techniques aimed at optimizing web content so that it is more easily discovered by search engines like Google, Bing, and others. By improving factors such as keyword relevance, website structure, and backlink quality, SEO helps ensure that content appears more prominently in search engine results pages (SERPs).

When content is optimized for search engines, it is more likely to rank higher for specific search queries, making it easier for users to find that content when they search for related topics. This increased visibility is crucial for driving organic traffic to websites, as users are more inclined to click on higher-ranked links. Therefore, effective SEO practices can significantly improve a website's chances of being found by its target audience.

The other options, while all relating to online content in some way, do not accurately capture the main function of SEO in this context.
