What are Open Graph tags?
Open Graph (OG) tags are meta tags in your page's HTML that control how your content appears when shared on social media. Without OG tags, Facebook, LinkedIn, and messaging apps may display a random image or no preview at all.
What is the recommended OG image size?
Facebook and LinkedIn recommend 1200×630px for OG images. Twitter (now X) recommends 1200×600px for summary_large_image cards. Use a clear product image or branded graphic — this is what people see before deciding to click.
Do OG tags help SEO?
OG tags do not directly affect Google rankings, but they influence social click-through rates. A compelling og:image and og:description drives more traffic from social platforms, which indirectly contributes to brand signals Google considers.
How do I test if my OG tags are working?
Use Facebook's Sharing Debugger (developers.facebook.com/tools/debug) to preview your OG tags and force a cache refresh. For Twitter, use the Twitter Card Validator. Both are free.
