Trust flow measures which of the following?

Trust flow is a metric used to assess the quality of links pointing to a web page, focusing on the credibility and trustworthiness of those links. It specifically evaluates how authoritative the linking domains are, thereby reflecting the likelihood that a particular page is considered trustworthy. Trust flow takes into account the reputation and influence of the websites that link to the page, rather than its popularity or access speed. This makes it a valuable tool for SEO, as it helps users gauge the potential quality and reliability of a site based on the trustworthiness of its external links.

While other options, such as measuring the popularity of pages or the speed of access, are aspects of web performance and user engagement, they do not factor into the assessment of trust flow. The focus on authoritative links to a page is what makes the correct answer stand out in the context of evaluating a page’s trustworthiness.
