Incentivising web accessibility via a lottery-style contest

96.3% of the internet's top one million websites have accessibility issues. As a result, people with a wide variety of disabilities (from visual impairment to ADHD and dsylexia) are unable to access the content on the internet. Making websites accessible isn't hard (especially not with all the AI tools out there now); it's just not something most people bother about because the proportion of people who have such disabilities is relatively small. In other words, they just don't have a strong enough incentive to do it. And without an incentive, fixing accessibility issues will rarely make it to the top of the priority list.

I want to fix this incentive structure. One great approach seems to be to create a non-profit that regularly runs a lottery-style contest. First, the non-profit fundraises a pool of a few thousand dollars from donors and advertisers. Then, it declares an invitation-only accessibility contest. The non-profit identifies many relatively-popular websites that have major accessibility issues (either manually or via some software) and sends them an invite to this contest. If they accept the invite, they're given detailed instructions. Basically, they would need to fix their accessibility issues within a set period of time (a month perhaps). Of all the website owners who fixed their issues, you would randomly pick one or two and give the entire pool of money to them. 

Why might this work? Fixing the accessibility issues costs the company very little but right now there is no incentive. When they see a potential upside of thousands of dollars, I think they are more likely to put it up their priority list. 

The NGO can run this contest several times each year. Each iteration, thousands of websites are made accessible. And importantly, once a website has been made accessible, it will probably stay like that for several years and its development team would've learnt how to include accessibility best practices in their work. This has the potential to benefit thousands of individuals with disabilities, for a long time.
