Twitter Card vs. Open Graph: What's the Difference and Which to Use
Open Graph: The Universal Standard
Open Graph was created by Facebook in 2010 and has become the de facto standard adopted by almost every platform. Facebook, LinkedIn, Slack, Discord, WhatsApp, Telegram, and iMessage all read og: tags. It's the foundation you should build first.
Twitter Cards: The Supplement
Twitter created its own twitter: card tags for richer control over X/Twitter previews. The key tags are twitter:card (type — summary or summary_large_image), twitter:site (@username of site), twitter:creator (@author username). Twitter falls back to og: tags when twitter: tags are absent, so many sites only add twitter:card.
Minimal Tag Set That Works Everywhere
<meta property='og:title'>, <meta property='og:description'>, <meta property='og:image'>, <meta property='og:url'>, <meta name='twitter:card' content='summary_large_image'>. These 5 tags cover 99% of sharing scenarios across all platforms.
