Frequently asked questions
What is Open Graph?
Open Graph (OG) is a protocol created by Facebook that allows any web page to become a rich object in a social graph. When you share a URL on Facebook, LinkedIn, Slack, or Discord, the platform reads OG meta tags to generate a preview with title, description, and image.
Which OG tags are required?
The four required OG properties are: og:title (page title), og:type (e.g. "website", "article"), og:image (preview image URL), og:url (canonical URL). Without these, platforms fall back to guessing from page content, often with poor results.
What is the ideal og:image size?
Facebook recommends 1200×630px. Twitter cards: 1200×600px. LinkedIn: 1200×627px. Using 1200×630px covers all platforms. The image should be under 8MB. For og:image:width and og:image:height tags, specify dimensions to help platforms display without reprocessing.
What is a Twitter Card?
Twitter Cards are Twitter's equivalent of Open Graph — meta tags that control how your URL looks when shared on Twitter/X. Types: summary (small image + text), summary_large_image (large image + text), app (app install button), player (video/audio player). Use twitter:card, twitter:title, twitter:description, twitter:image.

Why OG tags matter
Pages without OG tags rely on platforms to guess the preview content — often resulting in the wrong image, truncated title, or no preview at all. A compelling OG preview increases click-through rates on social media significantly. Research consistently shows that posts with rich previews outperform text-only links.
OG tags for SEO
While OG tags don't directly affect Google rankings (Google generally ignores og: tags in favor of its own parsing), they indirectly impact SEO by improving social shareability and click-through rates. og:type and schema.org structured data together give search engines and social platforms the clearest signal about your content.
