Goal
- provide access to the information to users whose browsers or platforms don’t support the inclusion of objects or the technologies used by the included objects.
- facilitate the exploitation of that content by bots (especially web crawlers).
- simplify the presentation and/or reuse of the included content.
- Improve the accessibility of content for people with disabilities.
- Improve the way content is taken into account by search engines and indexing tools.
Implementation
Indicate the alternative to the objects included using one of the following solutions:
- The content of the HTML
objectelement; - The content of the
noembedHTML element; - The content present immediately before or after the object;
- A link to a page providing the alternative content, placed immediately before or after the object.
Control
This check requires the detection of the object and embed elements, taking into account that they may be generated by Javascript. For each page containing one of these elements:
- Disable support for third-party technologies in the browser.
- Ensure that alternative information is displayed, or that it is accessible through a link next to each object.
