LinkedIn OG requirements are fully met

LinkedIn's crawler (LinkedInBot) does not synthesize fallback values from page content the way some platforms do. If og:title, og:description, or og:image are absent on a page, LinkedIn renders a plain URL with no preview card. Per ogp.me, all three tags are required; LinkedIn enforces this strictly and caches the first result it crawls — meaning a page that went live without complete OG tags may show a degraded preview for months even after the tags are added, because LinkedIn's cache TTL is long and invalidation requires manual intervention via LinkedIn's Post Inspector. Relative og:image paths are an additional LinkedIn-specific failure: the crawler does not resolve relative URLs to absolute, so /og-image.png is treated as an unresolvable reference.

Ensure every page intended for LinkedIn sharing has explicit og:title, og:description, and og:image set at the page level — not just inherited from the root layout. Use an absolute URL for og:image:

const baseUrl = process.env.NEXT_PUBLIC_SITE_URL ?? 'https://yoursite.com'
openGraph: {
  images: [{ url: `${baseUrl}/og/blog/${params.slug}.png`, width: 1200, height: 630 }],
}

After deploying page-level OG tags, use LinkedIn's Post Inspector (linkedin.com/post-inspector) to force a re-crawl and clear the cached degraded preview.
