How to fix missing og title on Adobe Commerce (Magento)

Steps for Adobe Commerce (Magento)

1. In the Admin panel, go to Content → Configuration → select your store view → click 'Edit'.
2. Under 'Other Settings', expand the 'HTML Head' section. Here you can add default meta tags, but for og:title specifically you need to edit your theme layout.
3. Navigate to your custom theme folder at app/design/frontend/[Vendor]/[Theme]/Magento_Theme/layout/ and open or create default_head_blocks.xml.
4. Add an og:title tag using layout XML, or edit your theme's default.xml to include it in the <head> block.
5. A more maintainable approach: edit app/design/frontend/[Vendor]/[Theme]/Magento_Theme/templates/html/head/additional.phtml to output: <meta property="og:title" content="<?= $block->escapeHtml($this->getLayout()->getBlock('page.main.title')->getPageTitle()) ?>" />
6. For product pages specifically, the og:title should use the product name: in catalog/product/view.phtml or via a plugin/override, output the product name in the og:title tag.
7. Flush the Magento cache (System → Cache Management → Flush Cache) and verify using 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.
