I was looking at some of my referrers and I noticed someone from w3.org had linked to one of my articles. Turns out the link came from their new working draft on web content accessibility. I spent some time reading through the working draft and was amazed at the amount of good information in the document.
The document is a comprehensive guide of the techniques you can use to conform to web content accessibility guidelines. Although the guide is not written from a search engine marketing standpoint, most of the document’s techniques are applicable for search engine optimization.
