Context is King of Web 3.0
Relationships make context. How the things within a sphere of influence relate to an item creates the context of that item.
Relationships define things in a way that a static definition could never do.
This is the idea behind ontologies in Web 3.0 - in addition to the definition of a thing, the relationships between that thing and what it associates with are also defined. This allows the computer (or a person) to have a broader understanding of what that thing is by understanding how it relates to the things around it.
These relationships form a context and it is this context that the computer essentially understands.
Let's look at how this applies to keywords, your website and natural rankings.
In a silo structured architecture, The broadest concepts are discussed at the top, with each descending level of the website discussing more granular concepts.
A "silo" in a silo structured website contains ideas that relate to the term at the top of the silo. A silo that has "dog food" as the parent silo term would have articles under that silo page that all relate some how to "dog food".
The more tangent the relationship of these articles, the more obscure the theme of the silo becomes, making it more difficult to rank for the primary terms.
Keeping the theme tight, from and LSI perspective, allows the search engine to easily understand the relationship and the context of each of the articles in the silo. This enhances the ranking score.
It's the synergistic relationship between all the concepts that make the context. Let's take an example: "Apple". It's what's known as a polysemous word; it has a large "semantic field", or more than one meaning. The only way you know what I'm talking about for sure is by what's around the word "apple". What CONTEXT am I using it in. In this way google knows whether I should rank for fruit or electronics.
And, as you can see by the picture, the more context you have, the better picture you get and the more you understand what's going on. This means the larger the ontology and the more ontologies we have, and the more connections there are between them, the better we will be able to analyze the digital content we have and the more useful unexpected connections we'll be able to make that will paint a clearer picture of the situation. By zooming out as far as possible, the easier it is to find the simple solutions.
However, the context provided by a silo structured website is not just for search engine bots, it makes it easier for people to find the content on your website, too. And the meaning will be even more clear because the context is easily established.
This will most likely lead to an increase in opt-ins, sign-ups and sales. And that just makes good "cents" all the way around.
