Links are a routine part of online reading, sharing and communication. A link preview adds context before a page is opened, often showing a title, image, short description or website name. These details help readers understand what a link leads to and how it relates to the surrounding message.
What a link preview shows
A preview is a compact representation of a web page generated by the service displaying the link. It may appear as a card in a messaging app, social platform or other online interface. Depending on the service and the page, the card can include the page title, a summary, a thumbnail image and the website’s domain.
Much of this information comes from metadata included in the page’s HTML. Standards such as Open Graph provide fields for a title, description and image, while other metadata can supply related details. The platform reads available information and formats it according to its own design, so previews can look different across services.
Reading the destination details
The displayed domain is a useful point of orientation. It identifies the website associated with the page, while a title or description offers a quick indication of its subject. Readers can consider these elements together: the domain gives a sense of where the link leads, and the accompanying text explains what the page presents.

In some interfaces, the destination address is also visible when a user selects or expands the preview. These pieces of information serve different purposes: the label describes the link in its original context, and the preview provides a brief view of the destination page.
Link previews are especially useful when a message includes little explanation. A card can supply context at a glance, helping readers connect a shared page to a topic or discussion. When several links appear together, their titles and domains also make it easier to distinguish among the destinations before choosing one to open.
Why previews can vary
Preview content depends on both the source page and the platform displaying it. A website’s metadata may specify a preferred title, description or image. The receiving service then applies its own layout rules, which affect how much text appears and how images are cropped. Some services show only a domain and title, while others use a larger card with a descriptive image.
Updates to a page can also take time to appear in a preview, because platforms may store previously retrieved information for a period. This process, often called caching, helps services load shared links efficiently. As a result, a preview is best understood as a concise snapshot of information supplied by the page and rendered by the platform.
Using previews as part of online reading
A preview works alongside other familiar ways of navigating the web. Readers may look at the visible domain, note the page title and use the surrounding message to understand why a link was shared. Together, those details provide a simple overview of the destination without requiring the full page to load first.
For publishers and website owners, clear page titles and descriptions help previews communicate a page’s subject accurately. For readers, recognizing the elements in a preview makes shared links easier to interpret. Link previews therefore offer a practical layer of context between a link appearing in a message and the destination page itself.
