Why many blog posts underperform

Pain points we solve

• Your snippet doesn’t reflect the real headline or last updated date.
• Missing or low‑quality images limit visibility in certain surfaces.
• Hand‑written JSON‑LD triggers validator warnings and inconsistent results.
• Using NewsArticle without eligibility causes confusion and maintenance overhead.

How SwiftSchema helps

Solution

The BlogPosting generator guides the fields that matter — headline, high‑quality image(s), datePublished, and dateModified — while supporting author and publisher where helpful.

It outputs clean, copy‑ready JSON‑LD to paste once per post, keeping your metadata consistent and crawlable.

Use BlogPosting for blog content, Article for general articles, and reserve NewsArticle only for eligible news publishers.

How it works

What is BlogPosting structured data?

BlogPosting is the Schema.org subtype for content published within a blog. It inherits all Article properties while signaling that the piece belongs to an ongoing blog feed. When you provide structured data for posts, search engines can match snippets to the real headline, show the updated timestamp, and understand author/publisher attribution. This consistency helps your posts qualify for surfaces like Google Discover, Top Stories (if eligible), and AI-generated summaries that pull from structured metadata.

Use BlogPosting for editorial, marketing, or product-update posts that live in your

section. If the content is evergreen or part of a knowledge base, Article might be more fitting. Reserve NewsArticle for organizations that meet Google News standards (24/7 newsroom, publishing cadence, editorial staff). Using NewsArticle when you’re not a news publisher can create manual actions for “Misrepresentation” or “Spammy structured data.”

Required and high-impact properties

1. headline
   — matches the on-page H1. Keep under ~110 characters.
2. image
   — at least one high-quality, 1,200px-wide image (preferably 16:9). Provide absolute URLs.
3. datePublished
   — ISO 8601 format. Use the original publish date even if you migrate or recategorize the post.
4. dateModified
   — update only when you change substantive content; sync with your visible “Updated” badge.
5. author
   — Person or Organization; include
   name
   and optionally
   url
   ,
   image
   , and
   sameAs
   .
6. publisher
   — often the company behind the blog. Include logo (112×112 square or larger).
7. mainEntityOfPage
   — canonical URL of the post. Critical when syndicating to other sites.
8. articleSection
   — e.g., “Product Updates,” “Engineering,” “Marketing Tips.”
9. inLanguage
   — BCP 47 code (
   en-US
   ,
   de-DE
   ), especially if you serve multiple locales.
10. wordCount
    /
    description
    — optional but helpful for search features that categorize long/short reads.

Editorial prep before generating schema

• Finalize the headline, subhead, and hero image.
• Ensure the post includes at least one inline image that matches the hero or is large enough for Discover.
• Confirm the canonical URL and slug are set; avoid staging URLs in
  mainEntityOfPage
  .
• Gather author bios and photos so you can populate consistent
  author
  entries.
• Decide how you’ll manage updates: add a “Last updated” statement near the top so editors remember to change
  dateModified
  .

If you plan to embed video or audio, prepare VideoObject/AudioObject metadata. BlogPosting can link to these via

or fields.

Implementation checklist

1. Choose the subtype: BlogPosting for blog articles, Article for more static pieces, TechArticle for developer docs.
2. Collect assets: headline, canonical URL, hero image, publish/updated dates, author data, summary, tags/sections.
3. Generate JSON‑LD using the form below, filling optional fields like
   keywords
   ,
   speakable
   ,
   backstory
   , or
   about
   .
4. Embed once per post (ideally in the
   <head>
   ). Ensure your CMS doesn’t inject duplicate schema.
5. Validate via Rich Results Test and Schema Markup Validator; fix errors before publishing.
6. Monitor Discover/Search performance using Search Console filters for
   Search Appearance: Articles
   or
   Discover
   .
7. Automate updates: integrate the generator output into your CMS so schema updates whenever authors edit content.

Image and media best practices

• Use JPG/WebP with minimal compression artifacts (lazy-loaded images should still return 200 to crawlers).
• Provide multiple image URLs if you switch hero images seasonally.
• For posts with embedded video, include VideoObject schema as well and reference it from BlogPosting to tie the media to the post.
• Don’t host critical images on CDN paths that require cookies or tokens; keep them publicly accessible.

Date and update hygiene

• Only update
  dateModified
  when you add new sections, stats, or major rewrites—typo fixes don’t count.
• Keep a changelog in your CMS or version control so editors know when to update structured data.
• Standardize publish times (e.g., set to 09:00 UTC) to avoid timezone confusion.
• After major updates, re-request indexing via Search Console to ensure new metadata propagates quickly.

Workflow tips for teams

• Maintain an
  authors.json
  or CMS table with structured data for each contributor (name, job title, profile URL, image). Pull from it when generating BlogPosting schema to reduce manual errors.
• Add a pre-publish checklist that includes verifying image dimensions, updating
  dateModified
  , and running Rich Results Test.
• For multi-language blogs, include
  inLanguage
  and link alternate versions via hreflang tags so search engines understand the relationship.

Common Errors & Fixes

• Headline too long: keep it under ~110 characters; create a shorter schema headline if the marketing headline is longer.
• Missing imagery: provide high-quality, crawlable image URLs (absolute, HTTPS, accessible).
• Incorrect type: prefer BlogPosting/Article unless you meet news criteria.
• Stale timestamps: update
  dateModified
  only when making substantive edits and ensure the visible “Updated” label matches.
• Broken canonical: ensure
  mainEntityOfPage
  points to the live canonical URL, not UTM-laden or staging versions.
