Mobile SEO Best Practices: Complete Guide 2025

Understanding Mobile-First Indexing

Since 2019, Google primarily uses the mobile version of your site for indexing and ranking. This means your mobile site is now the "main" version that Google considers.

What Mobile-First Indexing Means

• Google crawls your mobile site first

• Desktop rankings are based on mobile site quality
• Mobile user experience affects overall SEO

Preparing for Mobile-First Indexing

• Ensure content parity between mobile and desktop
• Include all important content on mobile
• Make sure mobile site loads quickly
