As we explain on the dedicated page here, there are at least four (4) good reasons to develop an accessible website or mobile application:

• expand your audience – with an accessible site, you can really think that 100% of your target audience is seeing, reading, or listening to you
• improve your SEO – anything you do to increase the accessibility of your website will help your SEO
• build your (brand) image – to put it quickly, it’s a good point to have an accessible digital platform
• apply the rules – it’s now the law that all public websites and applications must comply with accessibility requirements. Don’t wait for the same to happen in the private sector to get up to speed
