What is considered the primary activity behind off-page optimization in SEO?

Building backlinks is recognized as the primary activity behind off-page optimization in SEO because it significantly influences how search engines assess the authority and relevance of a website. Backlinks are external links from other websites that point to your site, and they serve as a vote of confidence from one site to another. The more high-quality backlinks a site has, the more credible it appears to search engines, which can enhance its rankings in search results.

This aspect of off-page optimization is crucial because it extends beyond the website itself, engaging with other online entities. Backlinks not only help with SEO but can also drive referral traffic to your website. By earning these links from reputable sources, a website can improve its visibility and trustworthiness in the eyes of both users and search engines.

In contrast, creating internal links relates to on-page optimization, where the focus is on linking within one's own site. Improving website loading speed and updating website content also fall under on-page SEO efforts aimed at enhancing user experience and site performance, rather than engaging with external factors. Thus, building backlinks stands out as the key activity associated with off-page optimization in SEO.
