## TL;DR

Sitemaps expose site-level URL discovery hints, while structured data exposes page-level semantic hints that agents can use before deciding what to fetch, cite, or ignore.

## Core Explanation

Agents that research the web need more than raw links. A sitemap can point to important pages, media, update metadata, and content families. Structured data can identify what a page is about, which entity it represents, and which fields a publisher is explicitly declaring.

These signals are not a substitute for source verification. They help an agent build a crawl plan, prioritize pages, and collect candidate facts, but the final answer still needs reachable evidence, permission-aware fetching, and claim-level citation checks.
