Story: A user clicking on a link on the mobile web is shown a preview of the destinaton so that they can learn a quick definition and choose whether or not to continue on to the destination.
Outcomes: Link preview launched on mobile web stable (using code shared by desktop hovercards). On all projects. Desktop hovercards stable and scalable. Increase in link clicking is measurable and initial (maybe beta) impact available.
Rationale: Launching on Android has shown a massive increase in engagement and web survey data shows overwhelmingly positive feedback. Working on desktop code is a good first step towards cleaner codebases.
Numerical target: early beta should show 15% increase in engagement risks are that community and readers will not welcome this change
Notes: "Bernd has worked on a definition to capture link previews as ""impressions"" in the Refinery scripts. Something similar would likely need to be planned for the web, in partnership with Analytics.
Edge cache performance needs to be dealt with.
Alternatives include: growing HoverCards to work on mobile web, using RESTbase, or some combination thereof."
See T100726 for some discussion of the alpha feature.

As a user on the mobile site
I want to be able to view previews of links before clicking on them
So that I can get context quicker
Acceptance criteria:
* Code for this feature must live in the Hovercards extension
