og:site_name

The name of the overall website — displayed in social cards to identify the source site beneath the page title.

og:site_name provides the website name, distinct from the page title (og:title). Some social platforms display the site name as a smaller caption beneath the card title, identifying the source. LinkedIn shows it prominently; Facebook uses it more subtly.

Set og:site_name to your brand name consistently across all pages. It should be the human-readable name of your website, not the URL and not the individual page title. For a SaaS product, this would be the product name; for a media outlet, the publication name.

This tag is optional but provides cleaner social card rendering. Without it, platforms typically derive the source name from the domain name, which may be less branded (e.g., "seocheckpilot.com" instead of "SEOCheckPilot").
