How to fix missing og image on PrestaShop
Add an og:image meta tag to every page so that social media platforms and messaging apps display a rich, branded image preview whenever someone shares your store's link.
Steps for PrestaShop
- Go to Modules → Module Catalog and search for an SEO module such as 'SEO Expert' or 'Open Graph Tags' — install and configure it.
- In the module settings, map the og:image field to the product's cover/main image for product pages, and set a static fallback image URL for other page types.
- Alternatively, edit your theme's header.tpl file (located in themes/[your-theme]/templates/_partials/head.tpl) to manually add og:image meta tags using Smarty variables like {$product.cover.bySize.large_default.url}.
- Clear the PrestaShop cache (Advanced Parameters → Performance → Clear cache) and validate with the Meta Sharing Debugger.
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.
