My site is https://xxxxxxxxx.com (a wordpress.com based site), but do I need to add: https://non-www https://www. http://non-www http://www. ...to WMT tools to ensure that Google treats them all as one site, i.e the https://non-www version? Secondly, I have purchased several expired domains with good metrics and have also put them on wordpress sites, do I need to do the same for these to ensure the metrics pass from what were http://non-www sites to the https://non-www it now is? Thanks!
