Frequently Asked Questions

What is OpenGraph?

OpenGraph (OG) is a standard protocol originally created by Facebook that standardizes how URLs are displayed when shared on social media platforms and messaging apps.

Why do I need both Twitter and OpenGraph tags?

While some platforms gracefully fall back to OpenGraph, Twitter uses its own specific tags (like twitter:card) to ensure optimal rendering of large image previews.

What image size should I use for social previews?

For the 'summary_large_image' Twitter card and standard OG sharing, an image size of 1200x630 pixels with an aspect ratio of 1.91:1 works best.

Is the metadata uploaded to a server?

No. All tag generation and preview rendering occur entirely in your browser using local JavaScript.

Why isn't my image showing up when I share a link?

Ensure that your image URL is an absolute path (including https://) and that the image file is publicly accessible. Relative URLs will not work for social media bots.
