Content Depth
How thoroughly a piece of content actually covers its subject.
Industry Term
Full explanation
Content depth is how thoroughly a piece of content covers its subject, including the detail, evidence, and nuance behind a claim, rather than a surface-level summary.
Depth is not the same as length. A long page that restates the same point in different words is not deep; a short page that states a claim, explains the reasoning behind it, and addresses the obvious follow-up question can be. What is being measured is whether the substance is actually there, not the word count.
This matters more directly in AI search than it did in traditional SEO, because a system synthesizing an answer is choosing which sources to draw the actual explanation from, not just which page to rank first. A shallow page can still rank; it is far less likely to be the source a system pulls its reasoning from.
Why this matters
Thin definitions get passed over in favor of sources that actually explain something. Depth is what makes a page worth citing rather than merely indexing.
Example
Two pages both define "citation share" in one sentence. One stops there. The other goes on to explain how it is measured, what distinguishes it from a mention count, and why the comparison matters. A system synthesizing an answer about the concept has far more to draw from, and more reason to treat the second page as a source worth citing.
Where this sits
Content Depth belongs to Content & Authority Strategy, one of the seven layers of the Aingworth Glossary. Where this thinking connects back to real work: the structures and evidence a brand builds to earn recognition, not just publish content.
