Google Custom Domains are a simple solution for providing non-Blog*Spot URLs for blogs published on Blogger servers. They are very elegant in their design, which uses nothing special, just industry standard DNS referrals ("CNAME") to a load balancing DNS server. Neither the "CNAME" entry (on the server provided by the DNS registrar), nor the load balancing ("ghs.google.com") are anything innovative.
And that's what makes them so elegant.
But, there's a downside - they don't work, consistently. And the cases where they don't work are inconsistently similar to those cases where they do work.
- The DNS provider is one major weakness which is not, totally, Google's fault. Not all DNS registrars support "CNAME" referrals - some only support "A" referrals. Not all support staff, working for the registrars, know how to implement "CNAME" either. GoDaddy supports it, and their "Total DNS Control" wizard will let you create a "CNAME". But the process is confusing, and more than one hopeful Blogger has reported being told, when contacting GoDaddy personally, to use an "A" record.
- When attempting to publish a blog, after the proper "CNAME" referral has been setup and verified, the Blogger may see the monolithic error
Another blog is already hosted at this address.
- After publishing the blog successfully, to say "mydomain.com", the Blogger will frequently find that "www.mydomain.com" won't respond with the same content (generally, a 404 error is observed). This is in spite of the fact that
- With normal publishing to Blog*Spot, "www.myblog.blogspot.com" will, reliably, equal "myblog.blogspot.com".
- With Custom Domain publishing, "myblog.blogspot.com" will redirect to "mydomain.com", and "www.myblog.blogspot.com" will show the same content as "mydomain.com" (though remaining on "www.myblog.blogspot.com").
- Even when none of the above problems are observed, the various blog aliases publish asymmetrically, in a way that must be demonstrated, to be effectively explained.
- With the asymmetric publishing results, many Bloggers have found their search weights, and Page Ranks, dramatically reduced. This does not make them cooperative for further analysis.
- Having observed some or all of the above symptoms, some Bloggers try using a version of URL referral, sometimes when recommended by their DNS registrar. URL referral produces even more bizarre results, and still worse search weights and Page Ranks.
Not all Bloggers experience all of the above. Some Bloggers do, successfully, publish to a Custom Domain, with all 4 aliases showing identical content, though the "www.myblog.blogspot.com" irregularity is still normal. It's seldom that these cases are identified, though, as Bloggers with no problems seldom post in Google Blogger Help.
This needs to be fixed - tell Blogger that this is stupid.
