SEO & Metadata
Every published BlnkSpace page automatically generates a complete set of metadata — Open Graph tags, Twitter cards, canonical URLs, and a favicon — from your document's content. You can override any of these from Page Settings for full control over how your page appears in search results and link previews.
Automatic metadata
When you publish a page, BlnkSpace builds the following metadata automatically with no configuration required:
| Field | Source | Notes |
|---|---|---|
| Page title | Document title | Used as the browser tab title and the <title> tag. |
| OG title | Document title | Shown as the headline in link previews. |
| OG image | Auto-generated via /api/og | Generated from the title and icon. 1200×630px dark card. |
| Favicon | Document icon (emoji) | Emoji rendered as inline SVG data URI for the tab icon. |
| Canonical URL | Site primary host | Always points to the verified custom domain if set, else the subdomain. |
| robots | index: true, follow: true | Public pages are explicitly marked as indexable. |
| OG type | article | All document pages use the article OG type. |
| OG modified time | Document updatedAt | ISO 8601 timestamp of the last save. |
| Twitter card | summary_large_image | Shows the OG image as a large card on Twitter/X. |
Overriding metadata
All automatically generated values can be overridden from Page Settings → Appearance & SEO. Overrides are stored as seoOverrides on the document and take precedence over the auto-generated values at render time.
/api/og generator is not called.Auto-generated OG image
When no custom OG image is set, BlnkSpace generates one dynamically via the /api/og endpoint. The generated image shows the document title in large type centered on a dark background, with the page emoji icon above it. It is 1200×630px and served with appropriate cache headers.
Canonical URLs
BlnkSpace enforces a single canonical URL per page to prevent duplicate content in search engines. The canonical is always the primary host — the verified custom domain if one is set, otherwise the blnkspace.app subdomain.
If your page is accessible from both mysite.com and mysite.blnkspace.app, the canonical tag will always reference mysite.com once the custom domain is verified. Search engines will consolidate ranking signals to the canonical URL.
Indexing
Published pages are explicitly marked as index: true, follow: true in the robots meta tag. This means search engines will crawl and index them by default.
Sub-page URLs
Sub-pages (child documents) are published as nested paths under the root document's URL. A document titled "Getting Started" under a site at mysite.com would be published at mysite.com/getting-started. The slug is auto-generated from the document title and can be changed by renaming the document.
