I am wondering if I should map my blog to my domain as a subdomain or just leave it completely separate on the third party site?

I am primarily concerned with SEO and the ease of transitioning between content on my domain and on my blog. I know there will be a slight disconnect between my domain and a potential mapped subdomain but if it benefits my domain it shouldn't be an issue.

Also do backlinks get credited to my domain or subdomain or are they considered one and the same once they are mapped together? And can I create backlinks from the third party site even though it is mapped as a subdomain on my cash for gold domain?

a subdomain and 3rd party domain will have almost identical SEO benefit. They are considered different domains by google. So if you have a subdomain of your regular domain (blog or not) google sees it as a totally different site. If you are trying to get the blog to add value to the main domain then subdomains or 3rd party domains are propbably not what you want, and instead you want a directory for your blog. If you are using a 3rd party blogging service (blogger, wordpress.com hosted) then your only choice is to reverse proxy the /blog/ directory of your site to pull this content from their servers.

Works like a charm in NginX and Blogger. Let me know if that is what you want and I will post a config sample to reverse proxy.

# MYSITE.com/blog (Blogger blog.mysite.com) **** 
location ~* ^/blog/(.*) {

    # Variables so we can redirect later
    set $blog_url            'blog.mysite.com';
    set $url_full            '$1';

    # Update Variable So We Can Catch SSL 
    set $force_SSL    "${force_SSL}XX";

    if ($force_SSL = HTTPSWWWXX) {
     return 302 http://www.mysite.com/blog/$url_full;
     #rewrite ^ http:/$host$request_uri permanent;

    # Turn off SSL for Blog
    if ($ssl_protocol != "") {
     #rewrite ^   http://www.mysite.com$request_uri? permanent;
     return 302 http://www.mysite.com/blog/$url_full;

    # Make sure blog is only available under www domain
    if ( $host != 'www.mysite.com' ) {
      rewrite ^/(.*)$ http://www.mysite.com/$1 permanent;

    # Rewrite outbound text to new url | rewrite https for image sources
    subs_filter               blog.mysite.com/ www.mysite.com/blog/;

    more_set_headers          "Server: BLOGGER";
    more_clear_headers        'Cache-Control-*';
    more_clear_headers        'Alternate-Protocol*';
    add_header                Cache-Control "public, max-age=7200";
    etag                      on;
    expires                   2h;

    # Cache File Information
    open_file_cache           max=1000 inactive=500s;
    open_file_cache_valid     600s;
    open_file_cache_errors    on;

    # Gzip
    gzip                      on;
    gzip_vary                 on;
    gzip_http_version         1.0;

    gzip_types                text/plain text/css application/x-javascript text/xml application/xml application/xml+rss text/javascript;

    proxy_set_header          Accept-Encoding "";
    proxy_http_version        1.1;
    proxy_redirect            off;

    proxy_pass                http://$blog_url/$url_full;

  • It used to see subdomains exclusively as a completely different site, but now it realizes "hey they are the same in alot of ways". Both Google webmaster tools and analytics understand they are the same realm. You can however still use separate channels by setting the subdomain up with its own analytics and domain verify in GWT. Depends on the use case, but the G is def more flexible now.

  • Awesome thanks! I appreciate the feedback. And yes @Frank I would love to get the details on setting up a reverse proxy for my blogger. Sep 20, 2014 at 9:40
  • Please see updated answer with blogger Nginx

  • We use a custom build of NginX with a few extras like subs filter. We also have blogger setup as a custom subdomain blog.oursite.com. Also note in blogger you want to add a bit of javascript to catch the url and redirect it to your main site. We use blogger (although wordpress is much nicer) because we dont like the hassle of having wordpress installed, and plus we like being able to take advantage of Bloggers great Google+ intergration.
