How is off-page SEO measured?

Off-page SEO is primarily measured by the number and authority of links pointing to a site. This aspect of SEO focuses on the external signals that influence a site's ranking in search engines. High-quality backlinks from reputable websites indicate to search engines that the content is valuable and credible, which can lead to improved rankings. The more authoritative sites linking to a webpage, the more it enhances the site's perceived relevance and trustworthiness, thereby boosting its visibility in search results.

While other elements like web design, onsite content length, and user interaction metrics may affect a site's overall performance, they are more related to on-page SEO. On-page SEO is concerned with aspects present on the site itself, such as content quality, structure, and user experience, rather than external factors like backlinks. Hence, the focus on link quality and authority distinguishes off-page SEO from other types of optimization efforts.
