You see, there are killer looking sites out there that couldn’t validate even if you put it through a blender! And then there are those standard compliant websites that are so boring that they give Web Standards a really bad name. So what’s that have to do with marketable semantics, and what exactly are marketable semantics? Basically, they are the SEM advantage of semantically correct markup.

See, this site you’re at now is semantically made, but if you check hard enough, you just may find a miscellaneous error or two. See, the difference in hardcore Web Standards vs what I like to call “Real World Web Standards” is simple. If your markup fails at some checkpoint within the W3C’s standards due to a “plugin” if you’re using WordPress, or if you’d like to monetize your website which requires the use of a bit of accessible JavaScript – and it does not hinder the accessibility and usability of the page, your best attempts of W3C validation should go applauded, but excusable.
