Annotation Visualizer

A Google Docs-style reading experience: blog content on the right, linked margin notes on the left. Scroll either column and the other follows, with a live connector line drawn between every note and the section it annotates.

Linked Notes & Content

The left column (1/3) holds notes. The right column (2/3) holds the article. Scrolling one side syncs the other, the active pair is highlighted, and a connector line ties each note to its source.

Anatomy of an AI-Ready Page

Foundation

A page that performs in both classic search and AI-generated answers starts with a single, clear thesis. Before a word of body copy is written, the page should answer one question for one reader. Everything that follows is evidence for that promise — structure, media, and markup all exist to reinforce a claim the reader can grasp in seconds.

When the thesis is buried, both humans and crawlers have to work to reconstruct intent. A strong opening removes that tax and sets the frame for every section below.

Semantic Structure

Headings are not styling — they are a machine-readable outline. A logical h1 → h2 → h3 hierarchy lets assistive technology, search crawlers, and retrieval models understand how ideas nest. Skipping levels for visual effect breaks that contract.

Treat each section as a self-contained unit: one idea, a descriptive heading, and supporting copy. This is what makes content both navigable for people and parseable for machines.

Structured Data

Schema markup translates a page into explicit entities and relationships. Where prose is ambiguous, JSON-LD is precise: this is an article, written by this person, published on this date, about these things.

Deployed at scale, structured data is the difference between a page that hopes to be understood and one that states exactly what it is — the core idea behind productizing schema delivery.

Media & Accessibility

Images carry meaning only when they are described and dimensioned. Descriptive alt text makes visuals legible to screen readers and crawlers, while explicit width and height prevent layout shift.

Performance

Speed is a ranking and experience factor with concrete thresholds. Core Web Vitals set the bar: Largest Contentful Paint under 2.5s, Interaction to Next Paint under 200ms, and Cumulative Layout Shift under 0.1.

A page that misses these is penalized twice — once by users who bounce, and once by systems that fold experience signals into ranking.

Built For AI Retrieval

Clean, self-contained sections are what get cited in AI-generated answers. Retrieval models pull passages, not whole pages. When each section stands on its own — clear heading, complete thought — it becomes a quotable, chunk-able unit.

The same discipline that makes a page accessible and fast also makes it citable. Structure is the throughline from classic SEO to AI visibility.

Scroll either column, or click a note to jump to its linked section.
