Suppose I create a blog with SomeName in blogger.com or tumblr.com. So the address is SomeName.blogger.com or SomeName.tumblr.com. I need some clarification as to the situation when I want to use MyOwnDomain.com for the blog:
If I simply go to the control panel of my domain registrar and setup MyOwnDomain.com to redirect to SomeName.blogger.com, then I shall expect that the blog will show up in search results as "SomeName.blogger.com"?
If I add MyOwnDomain.com in blogger control panel and edit the A and CNAME records of MyOwnDomain.com with the information provided in blogger, then the blog will show up in search results as MyOwnDomain.com? Is this guaranteed?
Are there any other SEO dangers to using Blogger or Tumblr when you want to promote your own domain?
