Structural Signals
Enterprise web topology under the Five-Lens Model. Site Studies dissect a single anonymized site; industry reports aggregate across a cohort; field notes explain the method behind the work; and signal briefs are short, timely takes on what is shifting right now.

The Tech Sector's Empty Link Graph: Built for Browsers, Not Agents
Across ten Fortune 500 technology sites, an average of 32% of published content has no inbound editorial link anywhere, reaching 80% on one site whose entire graph is 312 pages joined by 415 links. Only 6% of their structured data is answer-shaped.
On the nine measurable sites, an average of 32% of published content has no inbound editorial link at all, invisible to any link-following AI agent, and as high as 80% on one. The cohort splits violently: one site links almost nothing to anything, another links almost everything to everything.

Citation Divergence
Ranking #1 on Google no longer means an AI will cite you. New data shows AI answer engines build their own map of what is worth quoting, and it barely overlaps with the search results page.
AI answer engines pick the sources they quote by their own logic, not Google's ranking. In one 15,000-query study, only 12% of AI-cited pages ranked in Google's top ten, and 80% ranked nowhere on Google at all for the question being answered.

The Five Lenses We Read Every Site Through
The fixed framework behind a Digital MRI: five lenses (Skeleton, Circulation, Organs, Health, Nervous System), the network-science metric under each, and what a failing lens looks like.
A graph of thousands of pages is too big to read by eye. We measure it through five fixed lenses, so the same question is asked of every site and the answers can be compared across an entire industry.

Finance's Invisible Web: The Content Nothing Links To
On ten of twelve Fortune 500 finance sites where it can be measured, an average of 35% of published content has no inbound link anywhere, present only in the XML sitemap, reaching 79% on the worst site. Only two payment networks block the very inventory that would let anyone check.
On the ten measurable sites, an average of 35% of published content has no inbound link at all, invisible to any link-following AI agent, and as high as 79% on one. Only two payment networks block or omit their sitemap, so a crawler cannot even list what they publish.

The Machine Majority
Cloudflare says most web requests now come from bots, not people. What the milestone means, what it does not mean, and why your site's link structure decides what this new majority can actually read.
Most requests on the web now come from machines that discover content by following links. A page with no link path does not exist for the new majority.

How We Read a Website Like a Map, Not a List
How a Digital MRI works: we crawl a site, turn it into a graph of pages and links, and read its structure through five lenses. Method only, no client data.
A website is not a stack of pages. It is a network, and the shape of that network decides what a search engine or an AI agent can actually find.

What Healthcare's Web Topology Reveals About AI Readiness
An analysis of eleven Fortune 500 healthcare sites finds that roughly one in four pages cannot be reached by following internal editorial links from the homepage, and that the topology failure modes which cripple one site rarely cripple the next in the same way.
One in four pages cannot be reached by following internal links.
