I2I: document-level infinite-scroll #12945
Description
Objective
Provide publishers the ability to show several articles/document by the user just scrolling (aka infinite-scroll).
Background
Many publisher use this kind of solution in their non-AMP sites to further user engagement by providing related content in the same stream, with no loading times or clicking. The following articles (aka recommendations) can be provided in-line in the component, loaded from a URL or provided by a 3rd party (eventually). To adjust for different client side restrictions, the recommendations could eventually be rendered in different ways, besides infinite-scroll, such as previews or a stream of A2A links.
Details
Suggested name: amp-content-discovery
Initial version will include:
- Support only inline JSON recommendations
- Limit number of articles in scroll to 3 or 4, until performance risks can be addressed
- Update URL and/or title in viewer
- Add new events in analytics
- Basic handling of fixed position elements
Features to be implemented later:
- More sensible management of fixed elements (e.g. refresh sticky ads)
- Collapsing of repeated or irrelevant elements
- Ability to hide/unhide elements at the bottom of the page
- Increase UI configuration options
- Support dynamic and 3rd party recommendations
Example
Publishers will add a one tag with inline recommendations:
<script type="application/json">
{
"recos": [
{
"image": "http://example.com/image1.jpg",
"title": "This is one another article",
"ampUrl": "http://example.com/article1.amp.html"
}, ...
]
}
</script>
</amp-X>
