Hi,

There's a blog that is part of the Magix online services. If you use that blog, you will find an option in the Website Maker settings that will automatically make a link to your personal blog appear in the navigation bar. So, in this case you kinda have an integration of both services. The blog is a separate service and the link will open up a new window, though. It doesn't integrate as actual page of your site.

If you're using some external blog site, I suppose the only way to add it to Website Maker would be via an external link.
