OpenGraph tags: the fallback summary you already own
OpenGraph tags give any reader a titled, described, illustrated summary of the page in a flat format that needs no parsing of the body.
Redundancy is the point
OpenGraph overlaps the title tag and meta description almost entirely. That redundancy is useful: different consumers read different fields, and a page that states its summary three ways is hard to misread.
It also costs nothing — the values are already written.
The image is the part people skip
og:image is frequently missing, which turns every shared link into a bare URL. Frameworks make this nearly free — Next.js generates OG images from a React component at build time.
1200x630 is the safe size.
