How to Preview Your Open Graph Social Card, for Free
A free, step by step guide to testing your social share preview. Check your Open Graph title, description, and image before publishing, so every link you share on LinkedIn, X, Slack, and beyond looks polished and earns the click.
The launch link that rendered as a gray box
I shared a launch post I had worked hard on, dropped the link into LinkedIn, and watched the preview render as a blank gray box with the wrong title underneath.
It looked broken, so it got ignored. People scrolling past had no reason to stop, because the card gave them nothing to react to. The content behind the link was strong, but the first impression was a placeholder, and the first impression is all most people ever see.
One blank card taught me what no analytics dashboard had. When your link is shared, the Open Graph card is your headline, your image, and your pitch all at once. If it is broken or empty, it does not matter how good the page is, because almost no one clicks through to find out.
Why your social card matters
Open Graph tags control how your link looks when it is shared anywhere, from social feeds to chat apps. That preview, the title, description, and image, is the first thing people judge.
- A missing or broken image makes even great content look careless.
- A weak or wrong title and description on the card gives people no reason to click.
- You only see the real preview after sharing, unless you test it first.
Testing the card before you publish turns a gamble into something you can see and fix.
See your card before you share it with the Open Graph / Social Card Preview
Our team at RankAI built an Open Graph / Social Card Preview, free to run.
You enter your title, description, and image details and it simulates how your social card will look before you publish.

What to do with your results
Once you can see your card, the highest impact moves are usually:
- Set a proper OG image. Use a clear image at the recommended dimensions so the card never renders blank.
- Write a share-worthy title and description. Make the card promise something worth clicking.
- Test before you post. Preview the card so the first share looks right the first time.
Re preview after editing your tags to confirm the card displays cleanly.
Frequently asked questions
What is Open Graph?
Open Graph is a set of meta tags that control how your link appears when shared on social platforms and chat apps, including the title, description, and preview image, known together as the social card.
What is the right Open Graph image size?
A common, safe choice is 1200 by 630 pixels, which displays cleanly across most platforms. The preview helps you confirm your image and text render correctly before you publish.
Why should I preview my social card before publishing?
Because a missing image or wrong title shows up only after you share, and by then the broken preview has already cost you clicks. Previewing lets you catch and fix it first.
Is the Open Graph Preview really free?
Yes. You can use it at rankai.ai/tools/open-graph-social-card-preview for free, and the more detailed Full AI Visibility Audit is also free once you add your name, email, and website.
Do Open Graph tags affect SEO?
Open Graph tags mainly affect how links look when shared, which drives clicks and engagement. They are not a direct ranking factor, but stronger sharing can grow traffic and the signals that come with it.
