Dictionary (New Word): Deep Link (#279)

# Word

#### Deep Link

# Meaning/Definition

A deep link is a URI (URL) that encodes a destination inside an app or
site—identifying a specific piece of content or a specific state (e.g.,
a product detail view, a prefilled checkout, a tab + filter)—so the user
can land there directly from an external source instead of starting at
the homepage.

In mobile, deep links typically use either a custom scheme
(myshopapp://...) or a web URL that can open the app (“universal/app
links”), with a fallback to the website/app store if the app isn’t
installed.

Examples:
- Link in an email:
`https://shop.example.com/products/12345?ref=newsletter`
- If the app is installed, tapping it opens the app to Product 12345
(optionally showing the “newsletter” promo/referrer).
- If the app isn’t installed, it opens the same product page on the web
(or can route to the app store).
