What is Open Graph?

Open Graph is a protocol - originally created by Facebook and now adopted almost everywhere - that lets a webpage tell social platforms exactly how it should appear when shared. The tags live in the <head> of your HTML and are invisible on the page itself, but they control the image, headline, and description on every share preview.

Setting up Open Graph is one of the highest-leverage SEO and marketing fixes you can make. A page with proper OG tags earns 2-3x more clicks on social shares than one without. This checker fetches any public URL, parses the og:* and twitter:* tags, and shows you exactly how Facebook, X, LinkedIn, and Google will render your page - plus the issues you should fix before your next share.

Always use absolute URLs

og:image and og:url must start with https://, not a relative path. Platforms that receive relative URLs usually drop the preview entirely.

Ship an og:image on every page

Even a generic site-wide fallback is better than nothing. Pages without og:image render as text-only links and see dramatically lower CTR.

Match og:title to your message

Do not reuse your SEO title verbatim. Social clicks respond to different hooks than Google clicks. A/B test headlines here the way you would an email subject line.

Refresh the cache after edits

Facebook, LinkedIn, and Slack aggressively cache previews. After updating OG tags on a live URL, run it through Facebook's Sharing Debugger to force a fresh scrape.

Frequently asked questions.

What is Open Graph?

Open Graph (OG) is a protocol developed by Facebook that controls how your page appears when shared on Facebook, LinkedIn, Slack, WhatsApp, iMessage, Discord, and nearly every other platform that renders link previews. The core tags are og:title, og:description, og:image, and og:url. Without them, social platforms fall back to guessing which title and image to show, usually producing ugly or low-click previews.

Why is my Open Graph image not showing up?

The most common causes are: (1) og:image is not an absolute URL (must start with https://), (2) the image is smaller than 200 × 200 pixels, (3) the image is larger than 8MB, (4) the image URL returns a non-200 status or redirect, or (5) the platform cached an old preview. For Facebook, use the official Sharing Debugger to clear the cache. For Twitter/X, use the Card Validator.

What image size should I use for Open Graph?

Use 1200 × 630 pixels for the best cross-platform results. Facebook, LinkedIn, and Slack all render this size cleanly as a large image card. The minimum is 600 × 315, but smaller images are typically rendered as small thumbnails beside the title instead of a dominant hero image.

Do I need both Open Graph and Twitter Card tags?

Not strictly. Twitter (X) will fall back to Open Graph tags if no twitter:* tags are present. However, explicit Twitter Card tags give you more control - especially the twitter:card type (summary vs. summary_large_image) and a dedicated twitter:image that can differ from your OG image if needed. For most sites, mirroring Open Graph in Twitter tags is enough.

Does Open Graph affect Google rankings?

No, OG tags are not a ranking factor. However, they indirectly support SEO. Rich social previews get more clicks, more shares, and more backlinks, which all feed Google's engagement signals. Pages with strong OG setup consistently earn more organic visibility over time than pages without.

Why is my preview showing the wrong title or image?

Social platforms aggressively cache previews. If you updated your OG tags after a URL has already been shared, the old version is likely cached on Facebook or LinkedIn's side. Use Facebook's Sharing Debugger (developers.facebook.com/tools/debug) or LinkedIn's Post Inspector (linkedin.com/post-inspector) to force a refresh. Twitter/X typically updates within minutes of the first share after an edit.
