Meta tags live in the <head> of your HTML. They don't appear on the page, but they determine how your site looks in search results and on social media.
The Must-Haves
- Title Tag: The blue link in Google. Keep it under 60 characters.
- Meta Description: The snippet below the link. Keep it under 160 characters.
- Viewport: Essential for mobile responsiveness.
The Nice-to-Haves
- Open Graph (OG): Controls how your link looks on Facebook, LinkedIn, and Discord.
- Twitter Cards: Specific tags for Twitter previews.
