The Problem With Not Testing This

You spend time on a well-researched article. You optimize the headline, write a meta description, choose a strong header image. You publish it. A colleague shares it on Twitter. The preview card shows a broken image, a cut-off title, and a description pulled from random page text.

It happens all the time — and it's entirely preventable. The OpenGraph preview tool lets you see exactly what your link will look like before anyone shares it.

What OpenGraph Meta Tags Are

When someone pastes your URL into Twitter, Facebook, LinkedIn, or any messaging app that generates link previews, the platform's bot crawls your page and reads specific HTML tags from the <head> section. These tags are called OpenGraph (OG) tags, defined by a protocol created by Facebook.

The essential ones:

<meta property="og:title" content="Your Article Title Here" />
<meta property="og:description" content="A compelling 1–2 sentence summary." />
<meta property="og:image" content="https://yourdomain.com/header-image.jpg" />
<meta property="og:url" content="https://yourdomain.com/your-article" />

<!-- Twitter-specific, required for large image card -->
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:title" content="Your Article Title Here" />
<meta name="twitter:description" content="A compelling 1–2 sentence summary." />
<meta name="twitter:image" content="https://yourdomain.com/header-image.jpg" />

Without these tags, platforms guessing your content often get it wrong.

How to Use the Preview Tool

Enter your planned title — this is what appears as the bold headline in the card.
Write your description — keep it to 155 characters or under to avoid truncation.
Paste your image URL — the image must be hosted live on a public URL; local file paths don't work because social bots need to fetch it from a server.
Add your domain — this shows as the source beneath the card.
Review the previews — the tool renders accurate mockups for Twitter/X large card and Facebook/LinkedIn standard card layouts.
Copy the generated HTML — paste it directly into your page's <head>.

The Right Image Size

This is where the most common mistakes happen. Each platform has different display ratios, but there's a universal safe size that works on all of them:

1200 × 630 pixels at a 1.91:1 ratio

At this size, your image will display without cropping on Twitter, Facebook, LinkedIn, Discord, Slack, WhatsApp, and iMessage. Using a portrait image (taller than wide) will get heavily cropped by most platforms.

Additional notes:

Keep important content away from the bottom-center — some platforms overlay the title here.
Use JPG for photos (smaller file size); PNG for text-heavy images (sharper text).
File size should be under 5MB; many platforms won't load very large images.

Common Use Cases

Blog posts and articles: Every new post should have a custom OG image designed for social sharing. Using the post header image often works, but test it here first.

Product pages: E-commerce product pages shared on social media should show the product clearly against a clean background — not the generic website header.

Course and webinar landing pages: Registration pages shared into professional networks need a title card that communicates value at a glance.

Podcast episodes: Custom episode artwork with the episode title makes shared links dramatically more clickable than a plain text link.

Events and announcements: Event pages shared as links are competing with everything else in a social feed. A well-designed OG image is the difference between a scroll-past and a click.

Common Mistakes to Avoid

Not including twitter:card meta tag: Without this, Twitter shows a tiny thumbnail instead of the large image card. This one missing tag kills your engagement on that platform.

Using a relative image URL: Your og:image must be an absolute URL (https://yourdomain.com/image.jpg), not a path like /images/header.jpg. Social bots can't resolve relative paths.

Image not publicly accessible: If your site is behind a login or on a staging domain, bots can't fetch your images. Always test with a publicly accessible URL.

Not invalidating the social cache: Once a platform has cached your OG data, it doesn't automatically re-fetch it when you update the image. Use Facebook's Sharing Debugger, Twitter's Card Validator, and LinkedIn's Post Inspector to force a refresh.

Frequently Asked Questions

Do OG tags affect SEO? Not directly. Google doesn't use OG tags for ranking. However, better social sharing cards lead to higher click-through rates from social media, which indirectly influences traffic and signals.

What if my CMS doesn't support OG tags? WordPress: install Yoast SEO or Rank Math — both handle OG tags automatically. Webflow, Squarespace, Shopify, and most modern CMSes have native fields for these under SEO settings.

Can I have different OG tags for each page? Yes, and you should. Each page's og:title and og:description should match that page's actual content. A blanket site-wide OG tag is much less effective.
