What
An anchor link is a web link that allows users to jump to a specific point on a web page. It saves them the need to scroll and skim read – and makes navigation easier. Anchor links are handy within a single long page as a Table of Contents, or when for example customer service needs to provide the customer with a link to a specific point on a website, e.g. particular answer in a FAQ list.
Where
An anchor can be added to any page in the WYSIWYG rich text editor.
Do
Use anchors to help visitors access certain content at a specific point on a web page.
Try to use descriptive anchor name but keep it as short as possible, and connect words with a dash, e.g. "anchor-link".
Don't
Don't overdo it and stuff pages with anchors, but use anchor links sparingly and purposefully. Also, keep in mind that anchor links to a different page are bound to break if the target page URL changes since anchor link URLs are not automatically redirected.
