OG Tags are Meta Tags that are used by Facebook for the express purpose of SEO.
Most content is shared to Facebook as a URL, so it's important that you mark up your website with Open Graph tags to take control over how your content appears on Facebook.
In StoreHippo, we have inbuilt support for OG tags which allows you to automatically update the tags. These tags provide the structured information about the page such as the title, description, preview image, and more.
