Can one OG image be reused?

Yes for small sites, but product, pricing, docs, and article pages usually perform better with route-specific preview images.

Does the image need alt text?

Open Graph images do not use normal img alt text, but the visible page should still include accessible image alternatives where images appear.

Fix guide

A missing Open Graph image finding means crawlers or link preview systems cannot build a complete visual card for the page.

Answer first

The scanner did not find a reachable og:image for one or more sampled pages, or the image URL was relative, blocked, or mismatched.

Detail 01

Generate a production preview image, publish it under a stable HTTPS URL, and add route-specific og:image and twitter:image tags.

Detail 02

Open the image URL directly, check dimensions near 1200 by 630, then re-scan the page and test major preview debuggers.
