This is such a unique and interesting tool and could have a huge impact on the world wide web. Accessibility has fallen behind the curve in the evolution of website design and aCe could well help bring it back to the front from my early testing.
I thought that our company website would be fairly compliant but I was quite wrong, especially for graphics. We certainly need to put work into fixing these accessibility issues.
The breakdown of each section and each test inside aCe is excellent. I love the way it puts the results into sections and explains each test/check in detail. I counted 50 checks altogether, which is very conclusive!
I'd also be very interested to see whether fixing issues highlighted be aCe has an impact on both SEO and CRO.
