What is og:site_name?
The og:site_name meta tag identifies the name of your website or brand as a whole, separate from the individual page title. It helps social platforms attribute your shared content to your brand.
How platforms use it
- Facebook — Displays the site name above the title in gray text
- Discord — Shows the site name as a header above the embed
- Slack — Displays it prominently at the top of the unfurled link
- Others — May use it for branding and attribution
Why should you add it?
- Brand recognition — Users see your brand name consistently across all shared links
- Trust signal — A recognized brand name increases click-through rates
- Differentiation — Distinguishes your content from other sources in a user's feed
- Cleaner titles — You don't need to include your brand in

How to fix it
<meta property="og:site_name" content="Your Brand Name" />Best practices
- Use your brand name, not the domain — "OpenGraph.to" is better than "opengraph.to"
- Keep it consistent — Use the same site name across all pages
- Keep it short — The brand name only, not a tagline
- Match your real brand — Use the name your audience recognizes
