The four tags you always need
Facebook, LinkedIn, and most platforms cache scraped metadata for days or weeks. If you update og tags and share the URL again, you will see the old preview until the cache expires. Facebook’s Sharing Debugger at developers.facebook.com/tools/debug/ shows exactly what Facebook sees and lets you force a refresh with “Scrape Again.” LinkedIn has a similar Post Inspector tool. Twitter’s Card Validator existed but has been deprecated; to force a Twitter refresh, append a dummy query parameter to the URL. Test every new page in at least one debugger before announcing a launch.
og:type and og:site_name
Many sites generate og images on demand using serverless functions or edge workers: Vercel OG, Cloudinary, or a homegrown Puppeteer job. The generator takes the page title and a template and produces a 1200x630 PNG with branded typography. This scales well for thousands of pages without designing each image manually. Cache the output aggressively because every social share will fetch it. A stale cache of a good image is better than a cache miss during a viral moment.
