# Implement Lazy Loading for Better Mobile Performance

Mobile Analyzer

## What is this warning?

Your page has resources (images, videos, or iframes) that are loading immediately even when they're not visible to the user. On mobile devices with limited bandwidth and processing power, this can significantly slow down the initial page load and waste users' data.

## How to Fix This Issue

### How to Fix It

#### The Problem

```
<img src="image.jpg" alt="...">
<iframe src="video.html"></iframe>
```

#### The Solution

Add the `loading="lazy"` attribute to images and iframes that are not immediately visible (below the fold).

```
<img src="image.jpg" alt="..." loading="lazy">
<iframe src="video.html" loading="lazy"></iframe>
```

#### Why This Works

Lazy loading defers the loading of off-screen resources until they're needed, reducing initial page weight and improving load times, especially beneficial for mobile users on slower connections.

### SEO Impact

This issue can affect your site's search engine rankings and user experience. Addressing it promptly helps ensure optimal performance and visibility in search results.
