Open Graph and Twitter Cards

The plugin writes social meta tags into the page <head> on the wp_head hook (priority 15). It also adds the Open Graph namespace prefixes to the <html> tag through the language_attributes filter.

Where tags are added

Tags are emitted on these page types:

Single product pages
Product category archives
Product tag archives
The shop page
Any other WooCommerce page

On a single product, the source data comes from the WooCommerce product. On category, tag, and shop pages the plugin uses the term or page title, description, and a fallback image.

Basic Open Graph tags

Emitted on every supported page:

og:title
og:description
og:type (product on a product page, website elsewhere)
og:url
og:site_name
og:image, plus og:image:secure_url, og:image:width, og:image:height, og:image:type, and og:image:alt for each image
og:locale

On a product, up to three images are emitted: the featured image first, then gallery images. The number of images can be changed with the wog_max_images_per_product filter. If a product has no image, a fallback image is used (the configured default social image, or the WooCommerce placeholder).

Product Open Graph tags (Facebook)

When Facebook output is enabled and the page is a product, these product tags are added:

fb:app_id (only when a Facebook App ID is configured)
product:price:amount and product:price:currency
product:availability (for example in stock, limited availability, out of stock)
product:condition (defaults to new, or the _condition product meta)
product:brand
product:category

Twitter Card tags

When X (Twitter) output is enabled:

twitter:card (product on a product page, otherwise summary_large_image)
twitter:site and twitter:creator (only when an X/Twitter username is configured)
twitter:title
twitter:description
twitter:image and twitter:image:alt
On a product, twitter:label1 / twitter:data1 for Price and twitter:label2 / twitter:data2 for Availability

LinkedIn, Pinterest, and WhatsApp

LinkedIn: when enabled, adds linkedin:title and linkedin:description. Note that LinkedIn itself reads standard og: tags; these extra tags are emitted in addition to the Open Graph tags.
Pinterest: when enabled, adds pinterest-rich-pin and repeats the product price and availability tags for Rich Pins.
WhatsApp: when enabled, adds an og:image:alt tag for the first image.

Custom title and description per product

If a product has a custom social title or description set on its Social Media Settings meta box, those values are used instead of the generated ones. See Per-Product Settings.

Enhanced product data

When Enhanced schema is enabled, the product meta data also carries retailer item id, item group id, color, size, material, GTIN, and MPN. These values are drawn from product attributes (pa_color, pa_size, pa_material) and common meta keys, and feed the Schema.org markup.
