With over 60% of web traffic coming from mobile devices, Google prioritizes mobile-friendly websites. If your site doesn't work well on mobile, you're unlikely to get AdSense approved.
Why Mobile Matters for AdSense
Google uses mobile-first indexing, meaning they primarily use the mobile version of your site for ranking and indexing. A poor mobile experience signals low quality.
