You may have caught our post last week in regards to moving an existing blogspot blog onto your own custom domain using Blogger's blogging platform, which can of course also be used to establish a new blog on your own domain too!
As they say a picture is worth a thousand words, and in this case a video is! This video will provide you with greater clarification for the steps you need to take in your Blogger dashboard to convert your blogspot blog or to begin a new one on your own domain. Now you can end any excuses for why you have not started to blog, if that describes you.
Happy blogging!
