What is cornerstone content?
Every site has a handful of pages that matter more than the rest: the definitive guide, the page that explains the core service, the piece that answers the question the business exists to answer. Cornerstone content is the deliberate version of that. These pages are longer, better researched and more carefully maintained than ordinary posts, they target the broad terms the brand most wants to own, and the site's internal linking is arranged so that related articles point up to them. The term was popularized by the Yoast SEO plugin, which lets you mark pages as cornerstone and warns when they are under-linked; the idea is older and also goes by pillar page or hub.
A cornerstone is not a landing page and not a blog post. It is the reference the rest of the site treats as the source.
Why it matters
Why cornerstone content matters
Search engines work out what a site is about partly from its structure. A site with fifty posts that all link to one thorough page about brand films has told Google, in the most reliable way available, that the brand films page is the one to rank for brand films. Without cornerstones, a site's authority on a topic is scattered across dozens of thin pages that compete with each other for the same term, which is keyword cannibalization by neglect.
For readers it is simpler: the cornerstone is the page you send someone to when they ask what you do. It is the page sales shares, the page press lands on, the page that has to be right.
In practice
How cornerstone content works in practice
- 01
Choose few. Four to ten cornerstones for most brand sites, one for each topic the business genuinely wants to own, each targeting a broad head term rather than a long-tail phrase. Write them to be complete: definition, context, how it works, examples, questions answered. Keep them evergreen by removing dates and news hooks from the body and scheduling a review every few months to update what has changed.

Then build the structure around them. Every related article links to its cornerstone with descriptive anchor text, the cornerstone links back out to the best supporting pieces, and the main navigation or a hub page makes the cornerstones reachable within a click or two of the homepage. When a new post goes up, linking it to its cornerstone is part of publishing, not an afterthought.

This glossary is built as cornerstone content. Each term is written to be the complete answer to one question, kept free of dates so it stays true, and linked to its neighbors so the whole collection reads as one reference rather than a thousand posts. Our industry pages, for luxury, fashion, sport and beauty, do the same job for the work: one page each that says what we make for that world, which the case studies and the glossary link up to.
Watch out
What people get wrong about cornerstone content
Marking too many. If twenty pages are cornerstones, none is; the structure only works when a few pages receive the links. The other mistake is writing the cornerstone once and leaving it, so that the most important page on the site is also the most out of date. And thinking length is the point: a cornerstone is long because the subject needs it, not to hit a word count.
