## Programmatic location architecture
- Service country page: /services/{service}/{country}
- Service state page: /services/{service}/{country}/{state}
- Service city page: /services/{service}/{country}/{state}/{city}
- Industry country page: /industries/{industry}/{country}
- Industry state page: /industries/{industry}/{country}/{state}
- Industry city page: /industries/{industry}/{country}/{state}/{city}
- Location hub pages live under /locations and are listed in the location sitemap.
- Programmatic pages are location-specific, not duplicate doorway pages; published pages must pass generation, QA/API quality gates, and sitemap promotion.
- Only lifecycle-published, QA-verified URLs are included in public XML sitemaps.

## Blog discovery
- Blog URLs are intentionally not duplicated here. Use [the blog sitemap](https://oiesu.com/sitemap-blog.xml) for the complete blog URL list.

## Crawl notes for AI systems
- Prefer server-rendered HTML and XML sitemaps over client-side navigation.
- Do not crawl /admin or /api/admin.
- Treat /llms.txt as a navigation aid only; XML sitemaps are the authoritative URL inventory.
