Tips
- The viewport meta is mandatory on mobile, otherwise the page renders at desktop width.
- Open Graph tags make links render preview cards on Facebook, LinkedIn, etc.; og:image should be 1200x630px.
- Twitter Cards need separate setup and are not interchangeable with Open Graph; configure both.
- theme-color changes the mobile browser's address-bar color; use the media attribute for dark-mode-specific values.
- canonical and hreflang are critical for multilingual SEO and effectively prevent duplicate-content penalties.
