Rule n° 119 - Videos are user-triggered.

The automatic video release is double-edged. On the one hand you "push" the video content towards your users, you make your site more dynamic (young, fresh, sexy etc.). On the other hand, you send large amounts of data without the explicit consent of the users, you take the risk of increasing the bounce rate and damaging your referencing. If you trigger your videos automatically (in autoplay), as some social networks do, you run the risk of seeing certain users accessing content that is dangerous or inappropriate for certain audiences, especially if you broadcast live video. In short, before automatically triggering your videos, think carefully.

  • Allow the user to control the video content when consulting the site.
  • Do not impose for the user the automatic triggering of video or any animated content.
  • Improve the accessibility of content for people with disabilities.


Do not create audio content which starts automatically and without explicit user action.

Do not incorporate in the page elements triggering the playback of an uncontrollable video for example with the video html element with the autoplay attribute or without the controls attribute.


In each page containing video content:

  • Check that there is no video content automatically activated when the page loads;
  • Check that there is no video content activated in an unpredictable way following a user action.

Overview and background

The 240 Opquast rules are defined and agreed upon by an extensive community of web professionals and academics. These web quality assurance 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. The most recent version, v4, 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.
