Digital Accessibility

Web accessibility for all

1/ What is Web accessibility? 

Digital accessibility refers to the practice of making a service accessible to as many people as possible. This means making content accessible to all people from any device (computer, tablet, mobile phone, etc.), whatever their network infrastructure, geographical location, or physical or mental ability. Very closely associated with eco-friendly design, making a website accessible requires the implementation of a number of rules.  

The French government has drafted its Référentiel général d’amélioration de l’accessibilité (RGAA) (General rules for the improvement of accessibility) to encourage players in the sector to optimise website accessibility. This is the reference document that the Kereis Group has decided to adhere to when developing its websites. 


2/ RGGA accessibility statement

Kereis is committed to making its websites accessible in compliance with article 47 of French law no. 2005-102 dated 11 February 2005. 

To this end, it implements the following strategy and actions:

3/ PageSpeed Insights obtained an average score of 98,5/100 from a computer and 97,5/100 from a mobile phone for its website pages.

The analysis was carried out on 6 pages on 13 December 2022 using Google’s PageSpeed Insights tool. This tool generates user experience reports for pages accessed via mobile devices and computers, and provides suggestions on how to improve these pages. 

Google developed an algorithm to display the most relevant content at the top of the search results. Since 2021, this algorithm has also taken Core Web Vitals into account in order to ensure the fast loading of pages, particularly on mobile devices. The PageSpeed Insight score is partially calculated based on these vitals:

  • Page performance
  • Page interactivity
  • Page stability
