Accelerated Mobile Pages

AMP (Accelerated Mobile Pages) is an open-source framework created to make mobile pages load faster.

In this guide, you’ll learn what AMP is, why it emerged, how it works, what benefits it can bring to different stakeholders, and what you need to change on your website to implement it correctly.

What is AMP?

AMP stands for “Accelerated Mobile Pages.” It’s an open-source framework introduced through a collaboration between Google and other technology and publishing companies. The goal is to build lightweight mobile pages that load very quickly.

AMP pages typically limit heavy JavaScript and CSS, rely on strict performance rules, and can be delivered efficiently via a Content Delivery Network (CDN).

Why AMP?

As mobile usage grew and mobile searches surpassed desktop in many markets, publishers and businesses faced higher expectations for fast page loads. AMP was designed to address this demand by prioritizing speed and stability on mobile devices.

The initiative aimed to create a system that benefits multiple stakeholders—advertisers, publishers, and users—by improving the overall browsing experience on mobile.

How the AMP project developed

The AMP project launched in 2015 with support from companies such as Google, WordPress, and Adobe. Early adoption was especially strong among major news publishers across multiple countries, with platforms like Twitter and LinkedIn participating as technology partners from the start.

Today, AMP is widely used in publishing, and WordPress users can implement AMP through plugins. In many commerce scenarios, however, adoption tends to be more selective due to design, tracking, and feature constraints.

Why AMP is a good idea

In many industries, smartphones became the primary way people access the internet: searching for local places, reading news, and shopping on the go. On mobile, speed matters—when a page takes too long, users often leave before it finishes loading.

AMP is designed specifically to create pages that load as fast as possible on mobile by reducing complexity and limiting resource-heavy elements.

Problem: websites that load too slowly

Load speed depends on connection quality and how much a page needs to download. Large files and too many requests can slow down a page even on a fast connection. Likewise, even a well-optimized page can feel slow on a weak network.

Solution: AMP

AMP can’t improve the user’s network speed, so it focuses on what it can control: reducing the work required to render a page. It limits JavaScript and CSS usage and enforces performance-friendly patterns so fewer resources are needed before a page becomes usable.

One key reason AMP can feel fast is the reduction of files and requests. Another factor is caching via proxy/CDN infrastructure, which can deliver content from a nearby location and help maintain consistent performance across regions.

AMP source code

AMP is based on well-known web technologies and is readable by standard servers. Three core components define AMP:

  • AMP HTML: A restricted HTML subset focused on essential elements and predictable performance.
  • AMP JavaScript: A framework runtime that enforces asynchronous loading and prevents render-blocking patterns.
  • AMP CDN: Optional caching and delivery via a global network to reduce latency and improve consistency.

Which changes are required to implement AMP?

AMP pages must follow specific HTML rules. Media elements are added using AMP-specific tags like amp-img, amp-video, amp-audio, or amp-iframe. For example, an AMP image can look like this:

<amp-img src="myimage.jpg" alt="Description of the image" height="200" width="300"></amp-img>

In addition, AMP pages typically include these required building blocks:

  • Document type: <!doctype html>
  • Top-level tag: <html amp>
  • Head and body: <head> and <body>
  • Canonical link: <link rel="canonical" href="https://www.example.com/original-page/" />
  • Charset: <meta charset="utf-8">
  • Viewport: <meta name="viewport" content="width=device-width,minimum-scale=1,initial-scale=1">
  • AMP runtime: <script async src="https://cdn.ampproject.org/v0.js"></script>
  • Noscript fallback: AMP boilerplate styles to prevent flashes while the runtime initializes.

The advantages of AMP for different stakeholder groups

AMP was designed to benefit multiple groups:

  • Advertisers: Ads can load asynchronously in supported formats, helping avoid layouts that block content rendering.
  • Publishers: Faster pages can improve engagement and reduce bounce rates, supporting stronger user signals over time.
  • Users: Pages feel faster and more reliable, especially on slower connections, which improves the overall experience.

AMP and mobile-first

AMP is only one approach to mobile optimization. Over time, the SEO industry has increasingly prioritized mobile usability, especially after major Google updates pushed websites toward mobile-friendly experiences.

Google’s search engine relies heavily on mobile content to form search results. That makes mobile performance critical—whether you use AMP, responsive design, separate mobile URLs, or Progressive Web Apps (PWAs).
