Open Graph Checker
This open graph checker and meta tags checker fetches a live public page, checks whether an og:image exists, and reviews the key SEO and social tags that affect search snippets and link previews.
Checks source HTML only. If a site injects tags only after client-side JavaScript runs, crawlers and this tool may not see them.
Based on current Open Graph and Google Search documentation, the most useful baseline checks are title, meta description, canonical, robots, og:title, og:description, og:image, og:url, og:type, and twitter:card metadata.
For this first version, I am intentionally not turning it into a full site crawler. It does not audit structured data, hreflang, sitemap files, Core Web Vitals, internal links, or rendered JavaScript DOM output. The goal here is a fast og image checker and website meta tags checker for live pages.
It checks the metadata social platforms use for link previews, especially og:title, og:description, og:url, og:type, and og:image.
It verifies whether a page declares an og:image URL, whether that URL resolves correctly, and whether it returns an actual image.
X cards can fall back to some Open Graph metadata, but an explicit twitter:card setup is still useful when you want predictable social previews.
The checks on this page are based on the platform and search documentation below.
