Mobile First Indexing: What It Is and How It Works

Mobile first indexing means Google primarily uses the mobile version of a website's content for indexing and ranking. This approach reflects how most users browse the web on mobile devices, so Google focuses on mobile content first.

⚙️

How It Works

Imagine Google as a librarian who organizes books based on what most readers use. Since most people now read on mobile devices, Google looks at the mobile version of your website first to decide how to rank it in search results.

Before mobile first indexing, Google mainly checked the desktop version of a site. But now, if your mobile site has less content or different information, Google will use that mobile content to rank your pages. This means your mobile site must be complete and easy to use.

Think of it like a restaurant menu: if the mobile menu is missing dishes or prices, customers (Google) might get confused or unhappy. So, your mobile site should have all the important details just like the desktop version.

Example

This example shows how to check if your website has a mobile-friendly meta tag and viewport settings, which are important for mobile first indexing.

html

<!DOCTYPE html>
<html lang="en">
<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>Mobile Friendly Page</title>
</head>
<body>
  <h1>Welcome to Our Mobile Friendly Site</h1>
  <p>This page is designed to work well on mobile devices.</p>
</body>
</html>

Output

A webpage with a heading and paragraph that scales properly on mobile devices.

When to Use

Mobile first indexing is not something you 'turn on'; it is Google's default way of indexing websites now. You should focus on it when designing or updating your website to ensure your mobile version has all the content, images, and structured data that your desktop site has.

Use mobile first indexing principles when:

Building a new website to ensure it is mobile-friendly from the start.
Updating content so mobile users get the same information as desktop users.
Improving SEO to maintain or improve your search rankings.

For example, an online store should make sure product descriptions and prices are visible and easy to read on mobile devices, not just on desktop.
