How to fix missing og image on Gatsby

Steps for Gatsby

1. Create or open your shared SEO component (e.g. src/components/Seo.jsx). This component will use Gatsby's built-in Head API (Gatsby ≥ 4.19) — no extra library needed.
2. Accept an `ogImage` prop (absolute URL string). Fall back to a default site-wide OG image stored in `static/` (e.g. `static/og-default.jpg`) whose absolute URL is pulled from `siteMetadata.siteUrl` via a `useStaticQuery` GraphQL call.
3. Inside the component's JSX (returned from the Head export or rendered inside <Head>), add the four required OG image tags: `og:image`, `og:image:width`, `og:image:height`, and `twitter:image`.
4. Export the `Seo` component and re-export it as the named `Head` export from every page file (e.g. `src/pages/index.jsx`, `src/pages/products/{product.handle}.jsx`) so Gatsby injects the tags into <head> at build time.
5. For dynamic pages (product/collection PDPs), pass the page's own image URL as the `ogImage` prop (sourced from your CMS/commerce API during `createPages` or via the page's GraphQL query).
6. Run `gatsby build && gatsby serve` and validate the tags with the LinkedIn Post Inspector or Facebook Sharing Debugger — confirm `og:image` resolves to a publicly reachable absolute URL.

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.
