Google: Obviously everyone wants to have great sitemaps

“Obviously everyone wants to have great sitemaps and they’re definitely useful for us for crawling new and updated content.” — John Mueller, Google
John Mueller’s comment from a Google Search Central office-hours session (the format was renamed from Webmaster Central Hangouts in 2020) is still the clearest official statement on why XML sitemaps matter. A site owner had asked about inconsistent breadcrumb rich results. Mueller explained that when search features render differently than expected, “our algorithms are trying to do something different than what you are trying to do.” He also clarified that sitemaps and rich results are separate systems: sitemaps help Google discover URLs, while rich results come from structured data markup on each page.
What Are Rich Results?
Rich results (formerly “rich snippets” until Google renamed them around 2017-2018) are enhanced search listings generated from structured data markup you add to a page, typically in JSON-LD format using schema.org vocabularies.
Rich results draw attention in search: stars, prices, event dates, FAQ expansions. Listings with rich results typically earn higher click-through rates, and in 2026 they’re also more likely to be cited in Google AI Overviews. Validate any structured data with Google’s Rich Results Test (which replaced the retired Structured Data Testing Tool).
Common Rich Result Types
- Article / BlogPosting, Breadcrumb, FAQPage, HowTo
- Product, Review, Recipe, Event, VideoObject
- Organization, LocalBusiness, JobPosting
Sitemaps in 2026
Mueller’s quote still lands, with a couple of tactical updates:
- XML sitemap limits remain 50,000 URLs and 50MB per file. Larger sites use a sitemap index.
- Google retired the old sitemap ping endpoint in 2023. Submit sitemaps in Google Search Console under Indexing → Sitemaps instead.
- Most sites only need a standard XML sitemap auto-generated by Yoast, Rank Math, or AIOSEO.
