Every page Loom serves includes proper SEO metadata with zero configuration beyond base_url in site.conf.
What's Generated
Meta tags:<title>, description, author, canonical, robots (noindex on 404).
Open Graph:og:type (website or article), og:title, og:description, og:url, og:site_name, og:image, article:author, article:published_time, article:tag.
Twitter Cards:twitter:card (summary_large_image when an image is present, otherwise summary), twitter:title, twitter:description, twitter:image.
JSON-LD:BlogPosting schema on posts (headline, datePublished, author, url, publisher). WebSite schema on the homepage. BreadcrumbList schema on posts, tag, and series pages for search engine trail rendering.
Breadcrumbs: Visible breadcrumb nav rendered at the top of post, tag, and series pages (e.g. Home › Tags › performance). Toggle with show_breadcrumbs = false in site.conf.
RSS:/feed.xml — RSS 2.0 with Atom self-link, latest 20 posts, per-post categories from tags.
Sitemap:/sitemap.xml — all posts, pages, tag pages, series pages, archives. Priority-weighted.
Robots:/robots.txt with sitemap reference.
Per-Post Metadata
Post excerpts (from frontmatter or auto-generated) are used as meta description and OG/Twitter descriptions. Tags become article:tag properties. The publish date populates article:published_time and datePublished in JSON-LD.
Set the social preview image via the image frontmatter field:
---
title: My Post
image: /images/cover.png
---
If image is omitted, Loom falls back to the first image embedded in the post body. Relative paths are resolved against base_url automatically.
