SEO

Crawlers still look for /robots.txt before they dig through your tree. Hugo can generate that file at build time from a template, so the Sitemap URL always matches your baseURL and you can add allow/disallow rules without maintaining a hand-copied static file.

Search and social previews on a Hugo blog are mostly template work: consistent titles, a real summary, a thumbnail, Open Graph / Twitter tags, structured data, and a sitemap. DevOpsTales does that in layouts/_default/baseof.html plus a JSON-LD partial—no SEO plugin required.
