Welcome to the Q&A Forum

I was recently running my SEO Moz report for my domain and saw a drastic drop in page rankings on the report. After some trouble shooting, I checked my Google Webmaster Tools and saw the "Preferred Domain for my Site has changed" the last week in which I saw the drastic drop. Under the "preferred domain" area, I have it set to www.marware.com but on most of the links to my site, it reads www.marware.com/ . We also have http://marware.com , but am not sure if this carries any relevance as the preferred domain is set for www.marware.com . Does the "/" make a difference in the "Preferred Domain" section? If so, how do I update it? Is there a way to confirm it is set up correctly? In the photo attached, what does "Linked Property" "Analytics Web Property" and "Associated Webmaster Tools Site" mean? Thanks in advance! T5tSCxm
