Open Graph preview tool
Enter your page URL or manually enter OG tags to see exactly how your page will appear when shared on social media.
Why Open Graph previews matter
When someone shares a URL on Facebook, LinkedIn, Slack, WhatsApp, or X (Twitter), those platforms fetch the page and read its Open Graph (OG) meta tags to generate a preview card. Without OG tags, the platform guesses, often picking a random image, a generic title, or no image at all. A poorly formatted preview can significantly reduce click-through rates from social shares.
The critical OG tags are: og:title (the headline of your share card), og:description (the supporting text, 2-3 sentences), and og:image (the thumbnail image). The image has the biggest visual impact, research from various social platforms consistently shows that posts with compelling images receive 2-3× more engagement than text-only or poorly imaged links.
Image specifications: Facebook and LinkedIn use a 1.91:1 ratio, 1200×630 pixels is the recommended resolution. X (Twitter) summary_large_image cards use 2:1, 1200×600 pixels. Always serve your OG image over HTTPS (HTTP images are blocked by most platforms) and keep file size under 8 MB for reliable loading. After deploying changes to OG tags, use Facebook's Sharing Debugger and LinkedIn's Post Inspector to clear cached previews and force a re-fetch.
Frequently asked questions

Facebook caches OG data aggressively. Use the Facebook Sharing Debugger to clear the cache and re-scrape your page.
Do OG tags affect SEO?
OG tags are not a direct Google ranking factor, but they improve social sharing appearance which drives traffic and engagement, indirect SEO benefits.
What is the difference between og:title and the title tag?
The title tag is for browser tabs and search engine results. og:title is specifically for social share cards. They should usually match but can differ, social cards can be more casual or engagement-focused.
