OGP (Open Graph Protocol) is a standard for displaying information about external sites on social media sites such as Facebook and Twitter, when the URL of an external site is shared on SNS due to its proper setting.
Of all social networks, there is no retweeting or sharing function and it does not spread in such a short period of time as Twitter or Facebook, but rather Insta, which has been said to be the original content that can deepen its relationship with fans over time.
