What are Open Graph Meta Tags?
Open Graph (OG) is a protocol created by Facebook that enables any web page to become a rich object in a social graph. When you share a URL on Facebook, LinkedIn, Pinterest, Slack, or WhatsApp, these platforms read the OG tags from the page's <head> to determine the title, description, image, and type of content to display in the preview card.
Without OG tags, platforms will attempt to auto-detect the content — often producing ugly, incorrect, or missing previews. By adding proper OG tags, you control exactly how your content appears when shared, dramatically improving click-through rates from social media.
FAQ
What size should the og:image be?
Facebook recommends 1200×630 pixels for the best display across all devices. The minimum size is 200×200 pixels. Use a JPG or PNG under 8MB. Avoid using images smaller than 600px wide as they may not display as large cards.
Do Open Graph tags affect SEO rankings?
OG tags are not a direct Google ranking factor. However, they improve social sharing performance (click-through rates) which can drive traffic and earn backlinks — both of which indirectly benefit SEO.
