What are the recommended dimensions and aspect ratio for Open Graph preview images?

The industry standard dimensions for Open Graph sharing images (og:image) are 1200 x 630 pixels, representing a 1.91:1 aspect ratio. This resolution ensures your social share card displays crisply across desktop feeds, high-DPI retina screens, and mobile messaging apps.

Why do Open Graph image tags require absolute URLs instead of relative paths?

Social media scrapers (like Facebook's crawler and Twitterbot) fetch metadata independently from your webpage HTML without executing browser path resolution. Relative paths (like /images/preview.jpg) will fail to load, resulting in blank preview cards. Always use full URLs (https://example.com/images/preview.jpg).

How can I clear social media cache if my preview image does not update after changes?

Major platforms cache Open Graph tags aggressively. Use the official platform debugging tools—Facebook Sharing Debugger, LinkedIn Post Inspector, and Twitter Card Validator—to force social crawlers to scrape and update cached preview metadata.

What is the difference between Twitter summary and summary_large_image card types?

The "summary" card displays a small square thumbnail image to the left of the title and description, whereas "summary_large_image" displays a prominent full-width banner image above the text, typically achieving significantly higher click-through rates.
