A client of mine had a blog that utilized ASP pages for some content. Recently they moved their site to a Linux-based server and installed Wordpress. They did not want to have all the ASP pages rewritten in PHP, so instead they are linking to a separate website for some pages.
My question is this, does this have any negative impacts on the main Wordpress website? My primary concern is SEO but if any other concerns come to mind I'm all ears.
