What is the goal of on-page SEO?

The goal of on-page SEO is to optimize all pages individually for search engines. This involves tweaking various elements within a webpage to improve its visibility and ranking in search engine results. Key factors include content quality, keyword usage, HTML tags, and internal linking. By focusing on these aspects, on-page SEO aims to enhance the relevance and usability of individual pages, making it easier for search engines to index and rank them effectively. This strategy is crucial for driving organic traffic to a website, ensuring that each page is not only optimized for keywords but also provides valuable and engaging content for users.

The other options focus on external factors (such as social media presence and backlinks) or aspects of user engagement that are not directly related to the optimization of the content and structure of individual web pages, which is the essence of on-page SEO.
