Law firm silo architecture done right — pillar pages, child rules, no-orphan discipline, anchor-text rules, cross-silo flow. The structural foundation.
Every page has a defined role — pillar, child, supporting article, or geo page — and the internal links between pages reflect those roles, not editorial preference or whatever was easy to remember when the writer was finishing the post.
Silo architecture is the discipline of deciding the link graph of a website before any new content is written, then enforcing that link graph as the structural law every page follows.
Law firm websites are particularly prone to architectural decay. They are usually built by a designer who picks pages from a checklist, then content is added year after year by different writers, each one linking wherever felt natural. Five years in, the site has 80 pages with no clear hierarchy, internal links that point at random, orphan pages that no one links to, and an authority graph Google reads as flat. Map-pack ranking decays, organic ranking decays, and no one can find the cause because there isn't a single cause — it's the cumulative effect of the link graph never having been engineered.
Silo architecture fixes this by treating the link graph as a structural decision made once, before content scales, and enforced from that point forward.
One per silo. Targets the broadest commercial keyword in that silo's topic. Links DOWN to all of its children. Receives links UP from all of its children. May cross-link to peer pillars in other silos for high-relevance topics.
A primary page within a silo, targeting a specific sub-topic exact-match keyword. Links UP to its parent pillar. Cross-links to siblings only when contextually relevant. Cross-links to corresponding pages in peer silos (e.g., Practice Area child to its Local SEO counterpart). Receives links from supporting articles within the silo.
A blog post, FAQ, or guide that targets long-tail queries within the silo's topic. Links UP to the most relevant child or pillar. Does not link out to other silos (the cross-silo link belongs to the child, not the supporting article).
City-specific or office-specific pages. Links to the relevant practice-area child. Receives links from supporting articles where geo is relevant. Operates as a parallel structure to the silo, not as part of it.
The Core30 silo discipline can be reduced to seven rules. They are simple in description and unforgiving in enforcement.
A page that's a child of two pillars confuses the topical fingerprint. Pick the closer parent.
Every page is linked to from at least one other page. Pages that exist but are not linked from anywhere have effectively been removed.
Every child is reachable in one hop from the pillar.
Every child has at least one upward link, contextual where possible.
The link from a Practice Area child to a Local SEO sibling is a structural decision, not an editorial one.
Branded, partial-match, exact-match, and generic anchors are mixed deliberately. No silo should have all-exact-match anchors pointing at one URL.
Quarterly architecture audits catch drift before it accumulates.
The site you are reading is the build. Three silos: Practice Area (pillar at /law-firm-seo-agency/), Local (pillar at /local-seo-for-law-firms/), Methodology (pillar at /core30-for-law-firms/). Each pillar links down to all 9 of its children. Each child links up to the pillar. The Methodology silo is the most-linked-to silo on the site — both commercial silos cite Methodology children wherever the discipline is contextually relevant. Methodology children link out to commercial silos with concrete examples.
Every page on this site renders its own related-pages spine and a full footer index, so the architecture is something you can watch working as you browse, not just a diagram we describe.
The most common mistake. A writer thinks linking from a Methodology supporting article to a Practice Area sibling makes the site more connected. It doesn't — it confuses the topical signal. Cross-silo links belong on the child level only, and only where the topic genuinely overlaps.
Pointing every internal link at one URL with the same exact-match anchor signals manipulation. Vary the anchor — same destination, different wording. The link still flows authority; the manipulation signal is muted.
A pillar that doesn't link down to its children is doing half the work. The down-links are the pillar's job. They don't have to be 9 lines of bullet anchors; they can be contextual references in the body copy. But every child must be reachable from the pillar.
Blog posts that don't link up to the silo they belong to are not feeding the link graph. Every supporting article should link up to the silo's pillar or the most relevant child.

The result is a site whose link graph is engineered and maintained — visible from any page that opens its footer.
