Web quality and user experience rules Discover the 240 Opquast rules and the certification

Overview and background

The 240 Opquast rules are defined and agreed upon by an extensive community of web professionals and academics. These web quality guidance rules started as a list of best practices 20 years ago. They have since been revised every five years and have been tried and tested via millions of web interactions by Opquast community’s customers, including the leading CMS communities which have developed plugins for WordPress, Drupal and Prestashop. Version 4 was established in 2020.

Each rule has individual technical sheets and the rules can be searched by project phase or various topics: e-commerce, data-privacy, internationalization, security, code, etc, or by themes: accessibility, SEO, mobile, privacy, and ecodesign. The complete checklist is available on a creative commons license BY-SA.

These foundational UX-QA rules (User Experience Quality Assurance) are also at the core of the Opquast certification, ‘Mastering Web Quality Assurance’, detailed below, which now has over 11,000 certified.

Broad application and benefits

The rules should be applied to your projects from the design phase through to post-implementation , and they should be understood by all professionals with web and customer experience (CX) responsibilities: from strategy to operations, marketers to project managers, and editorial to technical staff. The benefits of using this ruleset are numerous, including improving customer satisfaction, web performance, and e-commerce, and expanding your client base, while also decreasing your errors and costs.

The objective of these rules and the Opquast community mission is ‘making the web better’ for your customers and for everyone! Opquast rules cover the key major areas of risk that can negatively affect website users such as privacy, ecodesign, accessibility and security.

  • Since 2018, the GDPR applies to every company that deals with EU citizens, and the concern about privacy continues to grow all around the world. Opquast provides a set of rules to prevent the most obvious risks and infringements to users’ personal data.
  • Opquast rules cover all key accessibility errors which ‘WebAIMs’ yearly analysis identified as affecting 98.1% of the top 1,000,000 home pages (as mapped to W3C WCAG conformance failures).
  • Opquast covers key ecodesign rules to make the web more energy efficient and in turn provide a better user experience with a lesser carbon footprint.
  • 19 security rules which provide essential web quality advice to ensure the user has confidence that technical security precautions are in place to prevent prevalent fundamental risks.

The modern web user is becoming increasingly sensitive to such requirements being met. Only by embracing web QA strategies, which are fully inclusive and user-focused, will we begin to create a web of high enough quality that will be acceptable and accessible to enough people.
