title: How to add a page route with html extension on nextjs
body: <p>I need to convert a non-nextjs page to nextjs. In order to not lose my SEO ranking, I have to create the route with html extension. To make the picture look better, I am adding the folder structure down below.</p>
  <p><a href="https://i.stack.imgur.com/zO1Bn.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/zO1Bn.png" alt="enter image description here" /></a></p>
  <p>Unfortunately, this route ending up as 404 on the browser.</p>
  <p><a href="https://i.stack.imgur.com/iiUZy.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/iiUZy.png" alt="enter image description here" /></a></p>
  <p>What is the problem? Am I allowed to use Next.js routes like that with html extension?</p>
