Most things that you can do manually in the browser can be done using Puppeteer.Ī great way to elevate your Open-Graph-image game is to harness the power of Puppeteer by providing a link in your OG image tags that calls out to a serverless function that generates a screenshot of a browser page. “Headless” browsers allow you to automate your interactions with a browser-like environment via a command-line interface. Puppeteer is a Node library that provides a high-level API to control headless Chrome or Chromium.
But in a world of sensory overload, how do you ensure your OG images provide useful context to your audience for the link you are sharing?

OG meta tags are identified in the HTML by a property attribute prefixed with og.
Open Graph meta tags are used in the of an HTML page to expose information about web pages to social media platforms and other applications that unfurl URL metadata.
