Creator Guidelines & Practical Tips
When posting on Facebook / LinkedIn / X, keeping captions and subtitles within visible safe zones prevents your message from being covered by mobile app icons (like buttons, comment trays, usernames, or audio tags). For text posts, proper line spacing ensures your paragraphs remain clean and readable across both iOS and Android apps.
All previews and checks in Social Open Graph Meta Tag Generator & Live Preview run 100% client-side inside your web browser. Your drafts, captions, and media are never uploaded to any remote server, giving you complete privacy and instant feedback.

💡 Frequently Asked Questions
Q: What is the recommended size for Open Graph social share images?
The universal standard for social share thumbnail previews is 1200 x 630 pixels (approx. a 1.91:1 aspect ratio), saved as a high-quality JPG or PNG.
Q: How can I test my Open Graph tags after updating my website?
You can enter your published webpage address directly into official inspection tools like the Facebook Sharing Debugger or LinkedIn Post Inspector to scrape fresh metadata.
Q: How should I configure Open Graph and X card tags for a LinkedIn article with a 1200 × 630 hero image?
Set og:type to article, use an absolute og:url, og:title, og:description, og:image, og:image:width="1200", and og:image:height="630"; add twitter:card="summary_large_image" and matching twitter:image. Keep the headline around 55–65 characters and test the final server-rendered HTML in LinkedIn Post Inspector.
Q: Why does Facebook display the right og:image while X shows a blank or differently cropped card?
X can use twitter:image and twitter:card independently of the OG fallback, so define both explicitly and use summary_large_image with a 2:1-safe composition. Verify that the image is publicly reachable over HTTPS, under the platform's file-size limits, and not blocked by robots.txt, authentication, or hotlink protection.
