Six failure modes, in the order they cost you the most. Each one is invisible to the reports
you already run, because each one returns a healthy answer to the question those reports ask.
01
A page can return a success code and still show a visitor nothing
Discontinued products, emptied collections and quiet failures answer every automated check correctly while rendering an empty screen. They pass a status-code report, they spend crawl budget, and a model reads them as your answer to the question someone asked.
You receiveEvery affected URL, classified by how certain we are, with a screenshot of what the page actually renders.
02
Anything JavaScript assembles, the model never sees
AI crawlers do not execute JavaScript the way a browser does. Specifications, descriptions, prices and reviews built on the client are absent for them. The page looks finished to you and blank to the model.
You receiveA raw-versus-rendered comparison per template, with the missing elements named and before and after screenshots.
03
Structured data can be present and still be ignored
Two separate failures hide under one heading. Schema that is absent, and schema that is there but wrong or incomplete enough that nothing will use it. We check both, and whether either survives without JavaScript.
You receiveCoverage by page type, every error and warning by severity, and rich-result eligibility per template.
04
Robots rules written for search engines now block AI crawlers
A file edited years ago for a different set of bots still governs who reaches your pages, often on a subdomain nobody remembers owning. A model that cannot fetch the page has nothing to cite.
You receiveWhich AI crawlers are allowed and which are blocked, per host, with the exact rule responsible.
05
A response that arrives too slowly is a page nobody read
Slow first bytes, redirect chains and challenge pages served to anything that is not a browser. Crawlers give up sooner than people do, and a fetch abandoned halfway is indistinguishable from a page that was never published.
You receiveResponse behavior per template, and the pages where delivery is the reason nothing downstream works.
06
The rest of the web still links to pages you removed
Every replatform and redesign leaves internal links aimed at URLs that no longer resolve, and other sites keep sending people to the same dead addresses. Each one is a route into your catalog that ends in nothing.
You receiveEvery 404 we find, split by region where it applies, with the pages still linking to each one.
