Why Do Links Open in the Same Window?
On GovHub, we have a few best practices for browser behavior that we suggest following because they help provide a good experience for your visitors and ensure that we’re adhering to the accessibility standards that government agencies are required to follow.
By default, links should open in the same window as the page you're currently on. This applies to both internal links (links to pages on your website) and external links (links to pages on other websites).
Opening links in the same window keeps the user in control of their browsing experience. It allows them to easily navigate back and forth between pages without having to constantly switch between tabs. Additionally, it ensures that they don't lose track of their place on the original page.
Forcing links to open in a new window can be disruptive and disorienting for users, especially those who rely on assistive technologies to browse the web. When a link opens in a new tab, it can be difficult to keep track of which tab is associated with which page. This can lead to confusion and frustration, particularly for users with visual impairments or cognitive disabilities.
