Sounds like it could be part of SEO effort. If it can be checked programmatically then search engines should add accessibilty to their ranking algorithms. It worked for mobile.
Imagine the investment that would suddenly start in accessibility if Google publicly announced it was an important part of search engine rankings.
It's important to note that not every site on the web falls under ADA. The crucial part of this issue is that the business must have a physical “brick and mortar” location to fall under the ADA. Presumably purely online retail businesses are not affected.
I wonder if google can be sued for not making it part of the ranking thus misleading blind users... Interesting angle for a lawyer. I hope someone at google is reading this and mitigates that risk.
This was when css started to become useful and if you were able to make do with little outline and lots of css magic, google would be grateful. This was before the SEO craze, of course.
If that doesn't convince you, then have some pride in your craft, some attention to detail. Visually impaired users aren't the only ones annoyed by the fact that you couldn't be bothered with tab order. We have tools, you don't need me to tell you that you're lazy (or overworked, or underbudgetted...), the machine will do that for you.
For the SEO motivation to succeed, I think search engines would have to regress (by definition of "search engine" and its goals) to serve accessible results to users who don't need it. I'm not opposed to this as a solution, but it requires some interesting decisions: do governments stipulate how much of the search score for a given page is based on accessibility? Presumably it's a bad thing for governments to stipulate _how search engines work_. On the other hand, we could see search engines do this voluntarily; that would be cool and might just work because the search engine space isn't especially competitive, but if it ever becomes competitive, I don't think a gentleman's agreement to artificially boost accessible sites (at the expense of serving up the content that is genuinely most likely to satisfy a non-disabled person's query) is going to hold.
Note the distinction between accessibility and mobile--mobile was market-driven: lots and lots of Google users (as a percentage of total users and absolutely) search via mobile--it behooves Google to improve their search experience by boosting mobile-friendly results, and it therefore behooves sites to optimize accordingly. We're talking about boosting accessibility beyond its market value--I think this is good and right, but I wouldn't expect to solve the problem the same way as for mobile.
Yes, the incentives differ. Its just that if I imagne a more accessible web and try to reverse engineer the way how it come to be I end up with ranking algorithm adjustments. Availability bias, I know :-P
There is a lot of money in SEO. Even a rumor about Google adjusting its algorithm towards accessibility could trigger improvements.
In a way it's a bit frightening that Google have that power, but it does have the opportunity to be used for good.
