Most people reach websites from phones and tablets, so the mobile experience is now the main experience. Google also indexes the mobile version of your site first. If your site works poorly on a phone, it is working poorly for search too.

In this guide we explain what mobile SEO is and why it matters, what mobile-first indexing means, how to build a mobile-friendly site (responsive design, dynamic serving, separate mobile URLs), and how to do mobile SEO: speed, Core Web Vitals, content parity, headings, titles and descriptions, images, menus, buttons, forms, pop-ups, crawlable resources, lazy loading, canonicals, internal links, URLs, structured data, Search Console monitoring, keyword research, local and e-commerce tips, AMP and how to audit your mobile pages.

What Is Mobile SEO?

The optimization work that makes a website easy to use and easy to find for people searching on mobile devices.

Why Is Mobile SEO Important?

Why Is Mobile SEO Important?

Most searches and visits come from mobile, and Google evaluates your pages primarily through their mobile versions. See what is indexing and how SEO work is done.

What Is Mobile-First Indexing?

Google predominantly uses the mobile version of a page’s content for indexing and ranking. Content that exists only on desktop may not be seen.

How to Build a Mobile-Friendly Website

  • Responsive web design: one site that adapts to any screen. See responsive web design and our web design service.
  • Dynamic serving: the same URL serves different HTML by device.
  • Separate mobile URLs: a different address for mobile; harder to maintain.

Responsive design is the simplest and most recommended.

How to Do a Mobile SEO Analysis

Common Mobile SEO Mistakes

  • Reducing mobile content: removing important desktop content from the mobile version can make Google evaluate the page incompletely.
  • Using large images: big files made for desktop slow mobile pages.
  • Using small font sizes: users shouldn’t need to zoom to read.
  • Placing buttons too close together: causes mis-taps.
  • Complicating the mobile menu: too many categories make pages hard to find.
  • Using full-screen pop-ups: hard-to-close pop-ups that block content hurt the experience.
  • Blocking JavaScript resources: Googlebot needs access to the resources required to render the page.
  • Using different meta tags on mobile and desktop: differing robots, canonical or title tags can cause indexing problems.
  • Focusing only on the test score: mobile SEO is not just a PageSpeed score. Content quality, usability and conversion paths all matter. See what is a landing page.
