I have written my own very simple CMS and everything i publish on my page will go on the landing page (http://xyious.com). so every time i write a new page, regardless of where it ends up on the navigation, it will also go on the homepage, very much like a blog. Now i have already submitted a sitemap that tells google that the landing page changes very frequently (daily), although it doesn't change that often.
Is there any way to tell google that the landing page is essentially a blog ?
Is there a way to tell google that there is duplicate content because obviously the landing page has the same content as a page in the archives ?
