I've recently started a website and of course I'm trying to build backlinks. I've started a blogger blog as one way to do this yet I'm continually hounded by sales calls that tell me if I post a link to my site in a
.blogspot.com blog it doesnt actually point to my site and therefore get no credit for the link. I can't seem to find this information on my own so I'm not sure if it's "sales people crap" or the truth.
Am I wasting my time trying to build links this way? Do I really need another domain strictly for blogging or do the links in my blogger blog actually help my site?
