For the most part, the guidelines are cut-and-dry.
But, you do need to review the guidelines on a regular basis
because Google does update them. They don’t necessarily
announce changes to them, so you must be on alert.
One of the more recent changes to the guidelines was when
Google added a line about making sure you code your sites in
valid HTML and CSS, and that it should be validated with the W3C.
This does not necessarily mean that it will help in search (it can
through a user experience perspective due to better cross-
browser compatibility).
This is a different type of guide than most.
The goal of this guide is to present potential solutions to common
problems, so you are armed with actionable advice you can use on
your next website issue.
Doesn’t that sound like fun?
