How to fix missing og title on PrestaShop

Steps for PrestaShop

1. In your PrestaShop admin, go to Modules → Module Manager and install a module such as 'SEO Expert' or 'Open Graph Tags' to add og:title support site-wide.
2. Alternatively, edit your theme's head.tpl file (usually at themes/[your-theme]/templates/_partials/head.tpl) and add: <meta property="og:title" content="{$meta_title|escape:'htmlall':'UTF-8'}"> inside the <head> block.
3. The {$meta_title} variable is populated from each page's SEO title, which you can set per product by going to Catalog → Products → edit a product → SEO tab → 'Meta title' field.
4. Clear the PrestaShop cache (Advanced Parameters → Performance → Clear cache) and verify with Facebook Sharing Debugger.

What is missing og title?

The og:title tag is a small piece of HTML code — part of the Open Graph protocol — that tells social networks and messaging apps what title to display when someone shares a link to your store. Without it, platforms like Facebook, LinkedIn, Pinterest, and WhatsApp either guess a title (often pulling something ugly or irrelevant) or show no title at all. It lives in the <head> section of your page and looks like: <meta property="og:title" content="Your Page Title Here" />. It does not affect your visible page content — it only controls how your link previews appear when shared.

Every time a customer, blogger, or influencer shares a link to your store or product page, the og:title is the headline of that shared post — it's what makes someone stop scrolling and click. Missing or broken og:title tags mean your shared links look unfinished, unprofessional, or just plain wrong, which directly reduces click-through rates from social media. For ecommerce stores, social sharing is a significant free-traffic channel: a product shared on Facebook or Pinterest with a compelling, accurate title can drive meaningful revenue. Additionally, some search tools and third-party indexers use Open Graph data as a secondary signal for content relevance, so having it set correctly supports a consistent, trustworthy brand presence across the web.
