To redirect a your blogspot to another Blog or Website, just add a Meta Tag in the Header section of the blog as shown below:
  • Search for: <b:include data='blog' name='all-head-content'/>
  • Add this Meta Tag just after the above code: <meta content="0;url=http://YOUR NEW URL HERE" http-equiv="refresh"/>
    <meta name="robots" content="noindex,follow" />
  • Then Save the Template. That’s all! :)
