This is the simplest approach: You have a single website, built on AMP. Because AMP supports responsive design, it will work on the desktop too. We've already seen examples of responsive web pages throughout this book, so we won't go into much detail here. The important thing to remember about canonical AMP pages is that the canonical link should point to itself:
<link rel="canonical" href="https://example.com/theampdoc.html"/>
While we've seen throughout this book that AMP is both flexible and powerful, there will always be scenarios that it won't be possible to solve with AMP alone. If this applies to your project, then using canonical AMP as your sole web solution won't be an option, and you should consider some of the other options covered in this chapter.
