Questions
What is Open Graph?
A set of meta tags that tell social apps what to show when someone shares your link: the headline, the description and the image. Without them, each app guesses, often badly.
What size should og:image be?
1200 × 630 pixels, a 1.91:1 ratio, under 1 MB, as PNG, JPEG or WebP. Smaller images show as thumbnails or not at all, and SVG isn’t supported.
I changed my tags. Why does Facebook still show the old preview?
Social apps cache previews, sometimes for days. Facebook’s Sharing Debugger and LinkedIn’s Post Inspector let you ask them to fetch the page again. Our check always reads the live page.
Does X need its own tags?
Only twitter:card. For everything else X falls back to the Open Graph title, description and image.
