Understanding Open Graph (OG) Tags: Overview, Usage, and Examples

What are Open Graph (OG) Tags?
Open Graph (OG) tags are metadata added to web pages, originally introduced by Facebook in 2010. They control how a webpage's information appears on social media platforms like Facebook, Twitter, and LinkedIn. By using OG tags, websites can display rich media previews that enhance social sharing and engagement.

How Do Open Graph Tags Work?
OG tags are added to the <head> section of a webpage's HTML. When shared on social media, these tags enable platforms to pull the specified image, title, and description for a visually rich preview.
