On websites, the placement of the help button should be strategic to ensure it's visible regardless of the complexity of the site.

For a straightforward, user-friendly approach, a floating help button is ideal; it follows users as they scroll, offering constant, easy access. Alternatively, the help button can be found anchored in the website's footer, a common location where users tend to look for support options.

On more complex sites, incorporating the help link into the header can also be effective, placing assistance right at the top where it’s hard to miss. The goal is to ensure that wherever users are on your site, help is never more than a click away.
