Why this matters
Social and chat previews are often the first impression. A well-designed OG image lifts link CTR by 30-80% on social. No image = no preview card = scrolled past.
Dynamic OG images (Next.js ImageResponse, Vercel OG) can generate per-page cards automatically from page data — high impact, low maintenance.
