Article Structured Data Glossary for Forum Announcements
When forum administrators publish official policy updates, community milestones, or editorial newsletters, standard discussion markup does not always fit. While regular community debate threads typically align with community post markup as discussed in our guide to DiscussionForumPosting schema, staff-authored editorial statements benefit from structured article vocabularies. According to the Google Search Central documentation on Article structured data, applying these attributes helps search platforms interpret page titles, author credentials, publishing dates, and featured visual media. This glossary outlines the essential terms and structural parameters needed to implement this markup cleanly on forum platforms.
Core Schema Object Types
Article: The foundational schema.org classification applied to general news, blog, and written editorial pages. While no specific structured data properties are strictly mandatory to qualify for display features, declaring this type explicitly signals what the page represents to search engines.
NewsArticle: A specialized sub-classification of Article. This type is used when forum staff publish formal community journalism, organization press releases, or platform-wide news bulletins.
BlogPosting: An alternative specialized sub-classification of Article designed for blog-style entries, developer journals, or periodic administrative logs.
Textual and Attribution Properties
headline: A text attribute holding the title of the announcement. Search documentation recommends providing a concise title because lengthy headlines may be truncated when rendered on smaller screen displays.
publisher: An object referencing the Organization behind the forum publication. Unlike the individual author, this property conveys the overarching organization or site name.
jobTitle: An optional secondary property indicating an author's formal staff position, such as "Editor in Chief" or community manager, preventing that information from cluttering the name string.
honorificPrefix and honorificSuffix: Dedicated attributes for honorific titles such as "Dr", ensuring prefixes and suffixes remain outside the primary name field.
Author Identity Nomenclature
author: A recommended property defining the creator of the post. The value must be defined as either a Person or an Organization. It should never use generic classifications like Thing, nor should it mislabel a real human poster as an Organization.
author.name: A text field containing strictly the author's personal or organizational name. Implementation guidelines state that this field must not contain introductory text such as "posted by", publisher brands, or job roles.
author.url: A valid web link pointing directly to a page that uniquely verifies the author. Suitable destinations include a staff biographical page, a social media profile, an external bio, or an internal community profile marked up with dedicated profile structured data.
When structuring author information, community maintainers should observe these structural rules:
- Include every individual presented as an author on the public announcement page in the structured markup.
- Give each individual contributor their own distinct author field rather than combining multiple names into a single string.
- Connect profiles using valid external links or the sameAs property to reinforce identity signals across the wider web.
Temporal Properties
datePublished: A DateTime property recording when the announcement was first published. Values must follow the ISO 8601 format. Providing explicit timezone information is strongly advised; if omitted, Google defaults the value to the timezone used by Googlebot.
dateModified: A DateTime property noting when the editorial text was most recently updated or corrected, also formatted under ISO 8601 format. Although testing tools will not raise validation warnings if it is left out, adding it provides accurate freshness data to indexing engines.
Visual Media Dimensions and Parameters
image: A repeated property providing URLs or ImageObject entries for images representative of the announcement. Guidelines advise using images directly relevant to the post rather than forum header logos or generic decorative banners.
To qualify for optimal rendering across search features, images must meet clear technical criteria detailed in Google Search Central's guide to Article schema markup:
- Image URLs must be fully crawlable, indexable, and saved in a graphic format supported by Google Images.
- Images must achieve a minimum of 50K pixels when multiplying width and height.
- Publishers should provide multiple high-resolution images matching three specific aspect ratios: 16x9, 4x3, and 1x1.
Technical Setup and Canonical Rules
rel=canonical: The HTML link tag indicating the preferred URL for search engines. For multi-part announcements, canonical tags must point either to each individual page in the series or to a single "view-all" page, and not to page 1 of the multi-part series.
Rich Results Test: A validation tool used to check JSON-LD or Microdata syntax, uncover critical parsing errors, and identify missing recommended fields before deploying templates.
URL Inspection tool: A diagnostic interface inside Google Search Console used to inspect how search engines crawl the live rendered page, verifying that content is not accidentally blocked by robots.txt, noindex tags, or mandatory user login screens as part of broader forum SEO basics.
