Mobile First Indexing: The New Standard
Google predominantly uses the mobile version of the content for indexing and ranking. If your mobile site is an afterthought, your rankings will suffer.
Responsive Design isn't Enough
Simply squishing your desktop site onto a phone screen won't cut it. You need to design touch-first interfaces, ensure button sizes are adequate, and optimize font readability for smaller viewports.
Speed is Critical
Mobile users are often on unstable networks. Optimizing images, minifying code, and leveraging browser caching are non-negotiable for mobile performance metrics like Core Web Vitals.
