Common Questions About Theme Detection
What is a meta viewport tag?

Why is the viewport tag important for SEO?
A properly configured viewport tag ensures your website is mobile-friendly. Since Google uses mobile-first indexing, missing or incorrect viewport settings can negatively impact user experience and search rankings.
