Please help me with IP Canonicalization and WWW Problem

December 12, 2013 4.1k views
Hello guys, I just made a ghost blog with my domain today using Digitalocean. When I cheched to see my SEO status on Woorank its show that I have a problem with "IP Canonicalization". According to them: "Be careful, your server IP is not forwarding to your website's domain name. Search engines like Google™ are now able to index your website with its IP instead of its domain name. This will result in duplicate content" Plus I also want to do the WWW Resolve because my website without www doesn't redirect to www (or the opposite). It is duplicate content! I'm not sure if there is a way to fix this issue. One thing I'm sure of is that I set up the DNS correct on Namecheap. Please help. Thanks

What's the output of
ls /etc/nginx/sites-enabled
If you execute:
cat /etc/nginx/sites-enabled/default

What's listed in the ServerName directive?
