DESIGN YOUR SITE TO HAVE A CLEAR
CONCEPTUAL PAGE HIERARCHY
What is a clear conceptual page hierarchy? This means that your
site is organized by topical relevance.
You have the main topics of your site arranged as main topics, with
subtopics arranged underneath the main topics.
These are called SEO silos. SEO Silos are a great way to organize
the pages on your site according to topics.
The deeper the clear conceptual page hierarchy, the better. This
tells Google that your site is knowledgeable about the topic.
There are two schools of thought on this guideline – one believes
that you should never stray from a flat architecture – meaning
any page should not be more than three clicks deep from the
homepage.
