What are Open Graph tags and why do they matter?

Open Graph (OG) tags are snippets of HTML meta code placed in a page's <head> section. They control how your content appears when shared on social platforms like Twitter/X, LinkedIn, Slack, iMessage, and Facebook. Without them, platforms guess what to display — usually with poor results.

The four tags every page needs

  • og:title — The headline shown in the link preview (keep under 60 characters)
  • og:description — A supporting summary (150–160 characters is ideal)
  • og:image — The thumbnail image (1200×630px, JPEG or PNG)
  • twitter:card — Set to summary_large_image for the best Twitter layout

Why do bookmarks lose their previews?

OG tags change when sites redesign, change CMS, or update their codebase. A link you saved six months ago with a beautiful preview may now show a blank image — because the site removed or renamed its OG image path. Tools like Savebase let you archive the original preview thumbnail at the time of saving, so your collection stays visually consistent forever.

How this tool works

This inspector fetches the target URL server-side (bypassing browser CORS restrictions), reads up to the end of the HTML<head> section, and extracts all OG, Twitter Card, and standard meta tags. Results are scored out of 100 based on the presence and quality of the six most important tags.
