Open Graph Tags for Blog Posts: Share Previews That Match
Open Graph tags for blog posts: og:title, description, image, and URL consistency for social and AI previews—not schema markup 101.

Open Graph tags for blog posts control how links look when pasted in Slack, LinkedIn, Facebook, or messaging apps—not how Google ranks the body copy. Align og:title, og:description, og:image, and og:url with the page readers actually land on.
This page is Preview-Then-Share. It is not schema markup for SEO beginners. It is not featured image SEO (on-page hero). It is not canonical tags explained. It is not improve organic CTR (SERP snippets).

Preview-Then-Share
PREVIEW-THEN-SHARE
1. PUBLISH → title + description + featured_image set
2. VIEW → page source for og:* tags
3. MATCH → og:url = canonical HTTPS URL
4. DEBUG → platform sharing inspector
5. SHARE → only after preview looks right
GA4 may show AI Assistant or social as referral traffic—ugly previews still hurt clicks even when SEO impressions grow.
Minimum OG set for blogs
| Tag | Purpose |
|---|---|
og:title | Headline in preview—can match title tag or be shorter |
og:description | Supporting line—not keyword stuffing |
og:image | Absolute URL to image file |
og:url | Canonical post URL |
og:type | Often article on posts |
Optional but useful on articles:
article:published_timearticle:authorwhen accurate
Do not invent author entities you do not publish.
WordPress and SEO plugins
Most setups map:
- Post title →
og:title - Meta description →
og:description - Featured image →
og:image
Verify after changing only the SERP title in an SEO plugin—some fields decouple.
Checklist on one staging or live post:
- View source
- Search
og:title—does it match intent? - Confirm
og:imageis absolute HTTPS - Compare canonical link
href
CashPilot posts use featured_image in frontmatter; template should expose it as OG image—confirm on deploy.
Image rules that stop ugly crops
Platforms crop wide images to cards.
- Prefer ~1200×630 (or current platform guidance)
- Keep critical text centered—edges get clipped
- Avoid tiny logos floating in empty space
- Compress weight—slow OG images do not block rankings but annoy mobile sharers
If lazy-loading broke hero delivery, OG still uses the direct image URL—separate concern.
Regenerate heroes with the site generator when titles truncate in previews.
Twitter/X cards alongside OG
Many sites emit:
twitter:card— oftensummary_large_imagetwitter:title/twitter:description/twitter:image
Can mirror OG or override. Mismatched X cards vs LinkedIn OG confuse teams—pick one source of truth in the plugin.
Debugging failed previews
| Symptom | Likely cause |
|---|---|
| Wrong old title | Platform cache—use debugger to rescrape |
| No image | Missing featured image or relative URL |
| Generic homepage image | Theme fallback OG on posts |
| HTTP image on HTTPS site | Mixed content blocked |
| Two URLs same preview | og:url not set; platform guessed |
After site migration, rescrape top posts—OG caches stale fastest on high shares.
FAQ
OG vs meta description?
Meta description targets search snippets; OG description targets social cards. They can match but need not.
Pinterest?
Pinterest reads OG among other tags—good images matter for Pinterest traffic.
Email newsletters?
Some clients use OG for link cards—same fields help.
AI chat citations?
Surfaces vary; accurate title + description + clean URL still help any link unfurl.
Multiple og:image?
Some plugins list alternates. One strong image beats three weak ones.
Audit one live post
Publish or pick a post with a new hero. View source. Copy the URL into LinkedIn and Slack post composers (draft). If the preview lies about the topic, fix og:description or social image before you promote. Preview-Then-Share beats viral posting with a broken card.
