A Domain Root, With Blogger And Non Blogger Hosts

Some blog owners publish a domain, and try to combine a Blogger blog, and a non Blogger website, in the domain root.

They publish one host to the domain root - and the other to the "www" alias.

This combination may be supported by the non Blogger host - but Blogger blog reliability will suffer. And the readers may become confused, when they click to view the blog, and get the website - or vice versa.

There is a special relationship between the domain root and "www" alias. Blogger takes advantage of this relationship, to provide improved reliability for a blog, when published to a custom domain.

Ignoring the special relationship, and splitting the domain root and "www" alias, leads to confusion - and decreased blog reliability.

Please don't publish two different hosts into the domain root / "www" pair.

Please, don't combine a Blogger blog and a non Blogger website, in the domain root / "www" alias duality.

There are 3 mutually exclusive configurations, for combining a Blogger blog and a non Blogger website in a domain, which will produce a reliable blog. Your readers will be happier - and the search engines will index the blog better - if you stick to one of the 3 supported configurations.

Taking the 3 supported Blogger configurations, we can add a properly published non Blogger website - and produce 3 more possible variants.

  1. Non Blogger website published to the "site" alias.
  2. Non Blogger website published to the domain root.
  3. Non Blogger website published to the "www" alias.

Non Blogger website published to the "site" alias.

Here, the blog is published to the "www" alias, with the domain root redirected to the "www" alias - and the website is published to an additional virtual host, such as "site". This is a variant of the Blogger asymmetrical DNS configuration.

mydomain.com. 3600 IN A 216.239.32.21
mydomain.com. 3600 IN A 216.239.34.21
mydomain.com. 3600 IN A 216.239.36.21
mydomain.com. 3600 IN A 216.239.38.21
www.mydomain.com. 3600 IN CNAME ghs.google.com.
site.mydomain.com 3600 IN A 162.210.101.54

Non Blogger website published to the domain root.

Here, the blog is published to the "blog" alias - and the website is published to the domain root. The website may or may not support redirection of the "www" alias to the domain root. This is a variant of the Blogger additional virtual host DNS configuration.

mydomain.com. 3600 IN A 162.210.101.54
www.mydomain.com 3600 IN A 162.210.101.54
blog.mydomain.com 3600 IN CNAME ghs.google.com.

Non Blogger website published to the "www" alias.

Here, the blog is published to the "blog" alias - and the website is published to the "www" alias. The website may or may not support redirection of the domain root to the "www" alias. This is a variant of the Blogger additional virtual host DNS configuration.

mydomain.com 3600 IN A 162.210.101.54
www.mydomain.com 3600 IN A 162.210.101.54
blog.mydomain.com 3600 IN CNAME ghs.google.com.

Your blog will be more reliably online - and your readers will be happier. And happier readers leads to better search engine indexing - and to more readers.



#Blogger blogs published to custom domains use both the domain root / "www" alias, for reliable connectivity. Trying to publish a blog, and a non Blogger website, to the domain root / "www" alias, leads to confusion - and decreased reliability for the blog.
