The plugin prints a full set of meta tags and structured data in the head of every post, page and product of your site. The Data Crawler reads them, so your search results get the right title, picture, date, language and categories. Search engines and link previews on social networks read them too.
On every post, page and product
- Description: the excerpt, or the start of the content.
- Keywords: the category and the tags.
- Author, language and category (the name of the post type), and a canonical link.
- Open Graph: title, description, address, type (article, or product for WooCommerce products), site name, locale and picture, with its size and alternative text.
- Twitter Card: title, description and picture.
- Article details: publish and modified time, section, tags and author.
The picture is the featured image, or else the first image in the content, or else your site logo or site icon.
Structured data (JSON-LD)
- Article for posts and pages: headline, address, description, dates, picture, author and publisher.
- Product for WooCommerce products: name, address, description, picture, SKU, an offer with price, currency and availability, and the category.
- BreadcrumbList: the path of the most specific category of the post or product. The crawl turns it into the levels of the hierarchical filter.
Your own fields
Each Field Mapping adds a tag named after its field, for example <meta property="opensolr:brand_s" content="Acme">. WooCommerce products also get tags for their price, currency, gallery, attributes and category path.
Other pages
Archives, the home page and other pages that are not a single post get the locale tag only.
Good to know
The tags are always printed; there is no switch to turn them off. If another plugin of your site prints the same kind of tags, both sets appear in the page.
