Yahoo Link Preview

Yahoo Link Preview is a targeted page-fetching service operated by Yahoo to improve the messaging experience for its users. When a URL is included in a Yahoo Mail message, this bot retrieves the page's metadata and visual assets to create a 'rich card' preview. By displaying titles, descriptions, and thumbnail images directly within the email interface, it helps users understand the content of a link before clicking, while simultaneously driving traffic to the linked website.

The bot operates on an on-demand basis rather than performing broad, automated indexing of the web. It only visits specific URLs that have been explicitly shared by a Yahoo Mail user. This behavior ensures that the previews remain current and relevant to the context of the conversation. Webmasters can verify the bot's identity through its consistent User-Agent string and the official documentation provided on Yahoo's help portal.
