ONPAGE · SEO GLOSSARY

Open Graph Tags

Meta tags that control how a page appears when shared on Facebook, LinkedIn, Slack, and other platforms that read OG metadata.

Definition

Open Graph (OG) tags are `<meta property="og:...">` HTML tags that define how a page appears when shared on social platforms and in link previews. The essential tags are `og:title`, `og:description`, `og:image`, and `og:url`. Twitter/X uses its own `twitter:card` meta tags with a similar function. Without OG tags, platforms generate their own previews — often unflattering.

Why it matters for SEO

Social shares, Slack links, and Discord shares all pull from OG metadata. A missing or badly sized `og:image` means your content looks blank or broken when shared. Since AI crawler summaries and some scrapers also consume OG metadata, well-formed OG tags contribute to how your content is described in aggregators and AI-assisted tools. Images should be at least 1200×630px; smaller images render as low-quality thumbnails.

How DeepSEOAnalysis checks this

The audit checks every crawled page for `og:title`, `og:description`, `og:image`, and `og:url`. It flags missing tags, `og:image` URLs that return a 404, images too small for social cards (minimum 1200×630px recommended), and mismatches between `og:title` and the page `<title>`. The Open Graph preview tool lets you test social card previews before publishing.
