What is
AMP?
Web pages that are compelling, smooth, and load near instantaneously
AMP is a simple and robust format to ensure your website is fast, user-first, and makes money. AMP provides long-term success for your web strategy with distribution across popular platforms and reduced operating and development costs.
<amp-img class="resp-img"
alt="Desktop"
width="550"
height="368"
src="images/Desktop.jpeg">
</amp-img>
<style amp-custom>
.resp-img {
max-width: 700px;
}
</style>
Créez des expériences Web enthousiasmantes pour tous les utilisateurs du Web ouvert
AMP enables the creation of websites and ads that are consistently fast, beautiful and high-performing across devices and distribution platforms. Publishers and advertisers can decide how to present their content that emphasizes a user-first experience.
We are committed to improving speed across the board. If our site takes a long time to load, it doesn’t matter how great our journalism is, some people will leave the page before they see what’s there.

Composants intégrés
AMP HTML is HTML with some restrictions for reliable performance.
Though most tags in an AMP HTML page are regular HTML tags, some HTML tags are replaced with AMP-specific tags (see also HTML Tags in the AMP spec). These custom elements, called AMP HTML components, make common patterns easy to implement in a performant way.
For example, the amp-img tag provides full srcset support even in browsers that don’t support it yet. Learn how to create your first AMP HTML page.
AMP pages are discovered by search engines and other platforms through the HTML tag. You can choose to have a non-AMP version and an AMP version of your page, or just an AMP version.
Caches AMP
AMP pages can be cached for near instantaneous loading on the web. Platforms like Google run AMP caches to enable fast loading of your content from their service.
The Google AMP Cache is a proxy-based content delivery network for delivering all valid AMP documents. It fetches AMP HTML pages, caches them, and improves page performance automatically. When using the Google AMP Cache, the document, all JS files and all images load from the same origin that is using HTTP 2.0 for maximum efficiency.
The cache also comes with a built-in validation system which confirms that the page is guaranteed to work, and that it doesn't depend on external resources. The validation system runs a series of assertions confirming the page’s markup meets the AMP HTML specification.
Another version of the validator comes bundled with every AMP page. This version can log validation errors directly to the browser’s console when the page is rendered, allowing you to see how complex changes in your code might impact performance and user experience.
