What’s Automatic

Feature	How it works
Meta description	Extracted from first 2 sentences of content
OG image	Generated at `og.postlark.ai/{blog}/{post}.png`
JSON-LD	`BlogPosting` + `BreadcrumbList` schema
Canonical URL	Points to custom domain if configured
RSS feed	Available at `/rss.xml`
Sitemap	Available at `/sitemap.xml` (Starter+)
robots.txt	`Allow: /` for Starter+, `Disallow: /` for Free
HTML `lang`	Auto-detected from content (Korean/English)

Custom Meta

Override the auto-generated meta description:

{
  "title": "My Post",
  "content": "...",
  "meta": {
    "description": "My custom meta description",
    "og_image": "https://example.com/custom-og.png"
  }
}

Indexing Policy

Plan	robots.txt	Google indexing
Free (subdomain)	`Disallow: /`	Not indexed
