The main content is not usually the first thing on a webpage. This makes it difficult for screen reader users to locate the actual content. Skip links are used on websites to address this problem. These special links are placed at the top of each page to bypass navigation blocks and other decorative content.
A skip link should be the first link in a page and is normally hidden from view but should become visible when in focus.
The WP ADA Compliance Plugin automatically places skip links on your website, where required. Use our free single page scanner to see if your website uses skip links.
