It’s rare that a day goes by when somebody asks me a question, either about SEO or Accessibility, which doesn’t in some way require me to answer that “it depends.”

Sometimes, this comes across as a surprise: aren’t there guidelines which are supposed to regulate these things? Yes, there are. And, if people were to ask me “Does doing this comply with Google’s webmaster guidelines?” or “Will this be in compliance with the W3C’s Web Content Accessibility Guidelines, version 1?” then I could generally answer definitely one way or the other.
