It is like a lot of the new guideline’s language doesn't vary all that much from their previous guidelines.
But just like with previous guidelines, you have to read between the lines.
For example, they would say "use words that people would use to look for your content."
Well, that seems straightforward but it's actually very complicated because different people search for the same thing in different ways.
We're all different in how we describe the world because we come from different backgrounds and have different experiences.
While there are a lot of tools that will help you come up with keyword variations, a lot of them are just projections.
In fact, I learned firsthand that some of the biggest paid SEO tools out there can be way off the mark when it comes to traffic predictions for certain keyword combinations.
The bottom line?
I don't think the new guidelines really tell us anything that we don't already know.
Still, I do appreciate the fact that Google is using a more basic vocabulary when trying to communicate with the publisher community.
