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 Twit...
