YouTube Cards in Your Video are similar to Annotations
Annotations have been used for years to engage with viewers. More flexibility with the information shared through annotations is needed and – more importantly – having it to work on all screens especially mobiles. That’s why YouTube introduced ‘Cards’ in March 2015.
Cards can be seen as an evolution of annotations. They can inform viewers on other videos, merchandise, playlists, websites and more. They are available at any time during the video and they finally work on mobiles.
There are 6 types of cards available right now: Merchandise, Fundraising, Video, Playlist, Associated Website and Fan Funding. There’s a new ‘Cards’ tab in the Video Editor to create and edit them at any time.
Because Cards can work across mobile and desktop and they give more flexibility to share information, YouTube’s aim is to have them replace annotations eventually. This will only happen once ‘Cards’ can do everything annotations can do and more. http://youtubecreator.blogspot.co.uk/2015/03/make-your-videos-even-more-interactive.html
Add a Layer of Interactvity to Your Videos
Cards add another layer of interactivity to videos. A destination URL can be provided from a list of eligible sites and dependant on the card type, customisation of the title, image and call-to-action text can happen.
How YouTube cards work
At a designated time a teaser will be shown for a few seconds and for viewers who click on it, they can access the card directly. During the video, at any other time, and icon will appear when viewers hover over the player on a desktop or when the controls are showing on a mobile. The icon can be clicked to browse all the cards available on the video.
How cards are surfaced
The cards have been designed to be contextual to the video and should enable creators to reach their goals while providing the viewer with an enriched experience. As cards evolve, YouTube plan to optimize them to surface the most relevant teasers and cards based on performance, viewer behaviour and device usage.
Types of cards
Merchandise: They are similar to merch annotations; merchandise cards can promote a creator’s licensed merchandise directly from the video.
Fundraising: Fundraising cards link viewers to projects on whitelisted fundraising sites directly.
Video or playlist: Links to another public YouTube video or playlist which may interest the viewer of the current video. Linking to an individual video within a playlist will default to the playlist.
Associated website: Directly link to the creator’s associated website.
Fan Funding: Lets fans show their appreciation for specific channels videos, by making a direct monetary donation on the video page.
