What happened?

  • Title every iframe.
  • Limit permissions.
  • Prefer links if the embed is heavy or tracking-heavy.

  1. Embed with title.
  2. Lazy load.
  3. Offer “Open status page” link too.
  4. sandbox the iframe.
  5. Move embed below the fold.

Remember

Prefer official embeds. Title + lazy. Link fallback.
