Review
Useful when judging whether a preview explains the page quickly in a feed.
Verdict
Vercel's strongest previews are crisp and campaign-like. The interesting lesson is not just design quality; it is inventory coverage across every page type.
What works
- The homepage card has a specific message rather than a generic logo lockup.
- The blog has its own section-level OG image, which avoids overusing the homepage card.
- The visual language matches the product: technical, restrained, and high contrast.
Watchouts
- The sampled docs page did not expose obvious OG tags in the fetched HTML, which can leave crawlers with weaker fallback previews.
- Large sites need automated checks because one missing page type can be hard to notice manually.
Page variation study
The product question: does each page type get its own useful preview?
Why this matters for automatic OG images
A site with docs, blogs, templates, changelog entries, and product pages benefits from automatically generating a route-specific preview instead of hand-maintaining every asset.
