Hi, Zetar Don't worries about that. Because Google doesn't know. And doesnï¿½t care whether your site is ASP, HTML, or anything else.
But if you have to be more exact, all sites are HTML. Server-side languages like ASP generate HTML, and sendsit to the browser. If you hand-coded the HTML then the browser renders it in the same way. It doesn't care how it got there.
If you have re created your site then of course, there might be other SEO issues arising. But just switching away from ASP isn't one of them.
