What kind of page should receive a page quality (PQ) rating of Low or Lowest?

A page that did not load would receive a page quality (PQ) rating of Low or Lowest because the fundamental purpose of a web page is to deliver content to users. If a page fails to load, it cannot fulfill this basic function, resulting in an unhelpful user experience. Such pages are often considered low quality, as they do not provide any value or information to users attempting to access them.

While advertisements can be present on various pages, they do not inherently dictate page quality, nor does the presence of user-generated content mean the quality is compromised. Furthermore, popularity alone does not guarantee that a page is high quality; it is possible for a popular page to contain misleading information or unverified content, which would not warrant a high-quality rating. Thus, the inability of a page to load renders it unusable, leading to a clear classification as Low or Lowest in terms of quality.
