The PDF Accessibility Checklist That Also Fixes Your AI-Search Visibility
Tagged reading order, real alt text, and searchable text aren't just accessibility requirements — they're the same technical fixes that let Google, Bing, and AI answer engines actually parse your PDFs. Here's the checklist, the standards behind it, and where it breaks down.
Internal Linking for AI Search Retrieval: A Different Job Than PageRank
AI retrieval systems don't crawl a site the way a PageRank algorithm does — they chunk pages, embed passages, and lean on anchor text as disambiguating context. Here's what the research actually supports about internal link structure and AI citation, and what it doesn't.
Orphan Page Audits for AI Search: How to Find (and Fix) the Pages Crawlers Never See
An orphan page is a live page with zero internal links pointing to it — invisible to crawl-based discovery and doubly invisible to the low-timeout AI crawlers that never render JavaScript or follow deep site trees. Here's a real audit process for finding them, backed by named studies, not fabricated stats.
About Entity Home: A Technical Blueprint
Discover how an entity home page with sourced facts can boost AI visibility by 40%. Includes a step-by-step blueprint and research from KDD 2024.
sameAs Link Audit to Anchor Brand Entity for AI Search
sameAs doesn't rank pages — it tells Google and AI systems which Wikipedia page, Wikidata item, and social profiles all describe the same entity. Here's how to audit it correctly, and what it can't do for you.
Content Freshness and Schema to Signal Trust Without Gaming
Visible dates, dateModified schema, and actual content changes are three separate signals that both Google and AI answer engines check independently — and faking any one of them is a well-documented pattern Google has publicly pushed back on.
Citation Link Rot Audit to Fix Dead Links for AI Citability
Link rot doesn't just annoy human readers — it removes the retrievable evidence AI search engines need to verify and cite your content. Here's a research-backed process for auditing and fixing dead citations in evergreen pages.
Structure HTML Data Tables for AI Citation-Ready Evidence
A table that looks fine in a browser can still be invisible to an AI answer engine if it isn't built with real semantic markup. Here's what the research on table parsing, accessibility, and generative-engine optimization actually supports — and what it doesn't.
Research Asset Landing Pages That Support Retrieval: A Practical Build Guide
A standalone page hosting one study, dataset, or report gets extracted and cited by AI answer engines differently than a blog post does — here's what the actual research says about structure, schema, and what still isn't proven.
