Google AMP

Ghost supports AMP Accelerated Mobile Pages for the posts in your publication.


The AMP project is a Google led initiative that enables lightweight versions of any piece of content on a site which offers speed and performance your readers in the browser.

In Ghost, a single handlebars template is used to automatically render AMP versions of the posts on your site. The default amp.hbs template offers all of the basic functionality of AMP, but it's possible to build on top of this to include other AMP supported features if required!

The AMP feature is enabled by default, or you can disable it in the settings of Ghost admin if you'd prefer not to use it.


To access any post rendered using the amp.hbs template on your site, add /amp/ to the end of any post URL on your publication. The parent post also has a canonical link to it's AMP equivalent.


The amp context always uses the amp.hbs template. Ghost will look for this template within your theme files and use this by default.

The template structure is as follows:

├── /assets
|   └── /css
|       ├── screen.css
|   ├── /fonts
|   ├── /images
|   ├── /js
├── default.hbs
├── index.hbs [required]
└── post.hbs [required]
└── amp.hbs [optional]
└── package.json [required]

Check out the default template in full.


The amp context provides access to the post object which matches the route. As with all contexts in Ghost, all of the @blog global data is also available.

When outputting the post, you can use a block expression ({{#post}}{{/post}}) to drop into the post scope and access all of the attributes. See a full list of attributes.

AMP features

AMP consists of three different parts:

  • AMP JS
  • Google AMP Cache

AMP has many restrictions for optimal performance. For example, JavaScript can only be used in certain circumstances, CSS must be in the correct tags inside of the <head> section, and AMP HTML must be used instead of common HTML.

If you are making adjustments to your amp.hbs file, follow the documentation provided on the official AMP docs site.

Edited amp.hbs templates can be updated in your theme by uploading a .zip of your updated theme in Ghost admin.

Debugging AMP

Since AMP has strict restrictions, it's important to ensure that your code passes AMP validation. The quickest way to do this is to add #development=1 to the AMP URL, and check for validation errors in your browser console.


Because the amp context is using the post data, you can use almost every post helper inside of the {{#post}}{{/post}} block expression. In addition to this, there are three helpers especially for amp which are decribed below.


This helper belongs just before the </head> tag in amp.hbs and outputs structured data in JSON/LD, Facebook Open Graph and Twitter cards, as well as an RSS URL path. It is a simplified version of {{ghost_head}} for AMP.


This helper can exist just before the </head> tag in amp.hbs and can output the necessary javascript if your content contains a .gif, an <iframe> or an <audio> tag.


This helper transforms post content into valid AMP HTML.

  • <img> transforms to <amp-img>
  • .gif transforms to <amp-anim>
  • <iframe> transforms to <amp-iframe>
  • <audio> transforms to <amp-audio>

{{img_url}} helper

There are special requirements for using the {{img_url}} helper. It must be wrapped in an <amp-img> tag and must provide a width and height property. This only works for post images.


You've now got an understanding of how Ghost implements AMP pages on your publication, have an understanding of how the amp.hbs template works should you decide to develop it further for your site. Always refer to the official AMP documentation when making adjustments to your AMP template!
