The extension prints a full set of meta tags and structured data in the head of every standard page 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 page
- Description: the abstract, else the description of the page properties, else the start of the content, up to 320 characters.
- Keywords: the system categories of the page and the keywords of the page properties.
- Author, language and category ("Page"), and a canonical link, unless the page already has one, for example from the TYPO3 SEO extension.
- Open Graph: title, description, address, type, site name, locale and picture.
- Twitter Card: title, description and picture.
- Article details: published and modified time, section, tags and author.
The picture is the first image of the page's Media field.
Structured data (JSON-LD)
- Article: headline, address, description, dates, picture, author and publisher.
- BreadcrumbList: the path of the first system category of the page. 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:page_author_s" content="Jane Doe">.
Other pages
Folders, shortcuts and other pages that are not a standard page get the locale tag only. The search page gets its own title, description and canonical link, and a WebSite structured data block that tells search engines where your site's search is.
Good to know
The tags are always printed; there is no switch to turn them off. The title and description tags of the TYPO3 SEO extension stay as they are: the extension adds its tags next to them and skips the canonical link when one is already there.
