How to fix missing og image on Next.js (Headless)

Steps for Next.js (Headless)

1. Place a high-quality branded fallback image (e.g. og-image.jpg, 1200×630 px) inside the /public directory so it is served statically at /og-image.jpg.
2. In your root layout (app/layout.tsx) export a `metadata` object (or `generateMetadata`) that sets `openGraph.images` with the absolute URL of that fallback image — use `metadataBase` so Next.js can resolve relative paths to absolute URLs automatically.
3. Override `openGraph.images` inside every dynamic route's `generateMetadata` function (e.g. app/products/[slug]/page.tsx) to supply a product-specific image pulled from your commerce API, with the static fallback as a safe default.
4. For any remaining static pages (e.g. app/about/page.tsx, app/collections/page.tsx), export a local `metadata` object with `openGraph.images` set to at least the fallback URL.
5. Run `next build` and verify the rendered HTML contains `<meta property="og:image" content="https://…">` with a fully-qualified URL on every page type.
6. Optionally add `twitter:image` via `metadata.twitter.images` in the same objects so Twitter/X card previews also display the image.

What is missing og image?

The og:image tag is a small snippet of HTML code placed in the invisible "head" section of your web pages. It tells social networks (Facebook, LinkedIn, Pinterest, X/Twitter, iMessage, WhatsApp, Slack, and more) which image to show when someone shares or previews a link to your page. Without it, those platforms either show no image at all, pick one randomly from your page (often a logo, icon, or a totally irrelevant graphic), or display a plain grey box — all of which look unprofessional and untrustworthy. The Open Graph protocol (the "og:" prefix) is a widely adopted web standard originally created by Facebook and now used by virtually every major platform.

When a customer shares your product page in a Facebook group, on Pinterest, or in a WhatsApp message, the link preview is often the first visual impression a new potential buyer gets — before they ever visit your site. A missing or broken og:image means that preview is blank, random, or ugly, dramatically reducing click-through rates and undermining trust in your brand. Studies consistently show that posts with compelling images receive far more clicks, shares, and engagement than text-only links. For ecommerce stores especially, a crisp product image in a shared link can directly drive impulse purchases and word-of-mouth traffic at zero extra ad spend. There is also a secondary SEO benefit: platforms like Pinterest drive significant referral traffic, and proper og:image tagging is required for Rich Pins, which surface your product price and availability alongside the image.
