Dans les tâches de notation Page Quality (PQ, qualité de la page), vous pouvez rencontrer des pages affichant des messages d'erreur ou d'autres types de pages « cassées ». Demandez-vous si la page apporte de l'aide aux utilisateurs : le propriétaire du site a-t-il fait un effort pour que les utilisateurs qui visitent la page aient une bonne expérience et soient aidés à trouver ce qu'ils cherchent ? Les pages affichant un message d'erreur explicite (ou une page 404 personnalisée) sont souvent de qualité Medium, car elles ont tendance à communiquer clairement qu'il y a un problème et à aider les utilisateurs à naviguer vers d'autres pages, meilleures, du site. La note High (voire occasionnellement Highest) peut être utilisée pour la rare page de message d'erreur qui implique un haut niveau d'effort et du contenu original, et qui offre une expérience réellement satisfaisante aux utilisateurs. Les pages « cassées » sont souvent de qualité Low, parce que l'aspect cassé les empêche d'atteindre leur objectif, même si le problème est temporaire et sera probablement corrigé plus tard par le propriétaire du site. Cependant, les pages « cassées » doivent parfois être notées Lowest si le problème n'est pas temporaire et relève d'un problème systémique du site. Pour distinguer les pages de qualité Low (temporairement cassées) des pages de qualité Lowest (signe d'un problème systémique), vérifiez d'autres pages du même site. Si de nombreuses autres pages présentent le même problème, il y a un manque d'effort systémique de la part du propriétaire du site, ce qui justifie la note Lowest. Sinon, utilisez la note Low pour refléter le problème (espérons-le temporaire !) du MC de la page. Voici quelques exemples : Page web / type de contenu Caractéristiques de la page Note PQ et explication Lowest : créée délibérément sans MC (problème systémique)

Section 9.2, page 85

In PQ rating tasks, you may encounter pages with error messages or other types of "broken" pages. Please think about whether the page offers help for users—did the website owner make an effort to ensure that users visiting the page have a good experience and get help finding what they are looking for? Pages with an explicit error (or custom 404) message are often Medium quality, since they tend to clearly communicate that there's a problem and help users navigate to other/better pages on the website. A rating of High (or occasionally even Highest ) may be used for the rare error message page that involves a high level of effort and original content and provides a truly satisfying experience for users. Pages that are "broken" are often Low quality, because the broken aspect prevents them from achieving their purpose even if the problem is temporary and likely to be fixed later on by the website owner. However, sometimes "broken" pages should be rated Lowest if the problem is not temporary and instead is due to a systemic problem with the website. To differentiate between Low quality (temporarily broken) vs. Lowest quality (evidence of a systemic problem) pages, check other pages on the same website. If many other pages have the same problem, there is a systemic lack of effort on the part of the website owner that justifies the Lowest rating. Otherwise, use the Low rating to reflect the (hopefully temporary!) issue with the MC on the page. Here are some examples: Webpage/Type of Content Characteristics of the Page PQ Rating and Explanation Lowest: Deliberately created with no MC (systemic problem)

  • No MC
  • Content created with little to no effort, little to no originality, and little to no added value for website visitors This is an example of a page with no MC. You might think that the MC is “missing” due to a problem with this particular page, but in fact, this website has hundreds of pages that look the same—no MC, just Ads. This website shows Ads with little or no attempt to help users, and should be rated Lowest quality. Webpage/Type of Content Characteristics of the Page PQ Rating and Explanation Low: Page didn't fully load and has no MC (temporarily broken)
  • No MC (probably due to a temporary technical error)
  • Positive website reputation This page has no MC and no error message. It is an isolated example of a page with no MC or error message on a website for a reputable newspaper for a town in Michigan. All of the navigation links work, and the page was later fixed. This page can be viewed as lacking in effort (an error that was not caught before the page went live). Medium: Error page with custom 404 message
  • Nothing wrong, but nothing special This is an example of a “custom 404” page, alerting users that the URL they are trying to visit no longer exists. Some websites do a nice job of alerting users about a problem and providing helpful tips. This page is on a well-known merchant website with a good reputation. However, this particular page displays the bare minimum of content needed to explain the problem to users, and the only helpful content is a link to the homepage. High: Error page with custom 404 message
  • Satisfying MC: achieves the purpose of the page well
  • Positive website reputation This is an example of a “custom 404” page, alerting users that the URL they are trying to visit no longer exists. This website does a nice job of explaining the issue and providing helpful tips, including a search box. Highest: Error page with custom 404 message
  • Very satisfying MC: achieves the purpose of the page very well
  • Very positive website reputation This is an example of a “custom 404” page. These pages are designed to alert users that the URL they are trying to visit no longer exists. The MC of this page is the cartoon, the caption, and the search functionality, which is specific to the content of the website. It is clear that effort and talent was involved in the creation of the MC. This publication has a very positive reputation and is specifically known for its cartoons, which allows us to go as high as High+ to Highest. This is among the most clever, original, and satisfying custom 404 messages that can be found online!
