DNS - The Backbone Of Google Custom Domains

DNS, or the Domain Name System, is an important component in Blogger, and an essential component in a Blogger blog published to a Google Custom Domain. Whenever someone reports a problem with a custom domain published blog, I start my reply with a DNS analysis. Generally, I use an excerpted Dig log, and / or an HTTP trace, to show the problem objectively.

To understand the importance and meaning of the DNS analysis that I provide, you need to know several things

For insight in how DNS works, I'll offer you several external articles, of differing technical depth. As always, I'll alphabetise this list, so examine each one in turn.
And, you are welcome to "Google It", for possibly more discussions.

Now those of you with a plain old Blog*Spot blog are probably thinking
Hey what the heck Chuck, why should I care about this?
because native Blog*Spot blogs use Google DNS. Google provides addressing information for all web pages within the "*.blogger.com", "*.blogspot.com", and "*.google.com" name spaces. If your blog is still published to Blog*Spot, you have no need to read any further.

Blogger / Google does not provide addressing information for any web pages outside the "*.blogger.com", "*.blogspot.com", and "*.google.com" name spaces. They have no legal, moral, or technical justification for providing any such information, so they leave that to the public DNS infrastructure, and simply say
Point an address, in an external DNS server, to our servers, and we will take it from there.
Non BlogSpot URLs, whether they address content starting as a Blogger blog, a WordPress blog, or a Yahoo page, are all maintained in the public DNS infrastructure. Some URLs may even point to a domain that contains all 3, or more.

To setup a custom domain, you (or a third party, maybe a Blogger script like "Buy A Domain For Your Blog") has to setup the DNS configuration for your domain, in the DNS servers provided by your DNS Hosting Service. Separately, you may examine some righteous solutions, and alternately, some spurious solutions, showing the right ways and the wrong ways, respectively. Remember, for best results, pair the DNS entries properly, and avoid forwarding, DNS based or otherwise.

You may, depending upon your need and current availability of Google servers, choose any one of several reliable DNS configurations.

Having setup your DNS, you publish your blog. If you see a well known error
Server Not Found

Error 404

Fransiska,

I Googled on "how does dns work", and got a dozen or so pages of hits. The above 4 links are merely the most representative and interesting 4 from the first page.

Fransiska, Google is your friend.

Here is where I once again suggest that you ask a question in Blogger Help Forum: Something Is Broken, or in Nitecruzr Dot Net - Blogging, and use peer support to diagnose your problem.

Custom Domain Migration - Managing The Traffic

Your blog depends upon traffic for its success.

Anything that affects the traffic to your blog, such as any change in the URL, affects the success of your blog. Publishing the blog to a custom domain, like renaming the blog, will affect traffic to your blog. The effects of the change will vary from blog to blog, because of the different traffic to every different blog.Followers. People who find your blog because of recommendations by other people.Search engines. Robotic processes which methodically surf your blog, and provide dynamic indexing to people who search for information.Subscribers. People who read your content from their newsfeed reader, such as the dashboard Reading List.Viewers. People who read your content from their browser.No two blogs are the same - and no two blogs will have the same combinations of traffic sources.

Stats Components Are Significant, In Their Own Context

One popular Stats related accessory, which displays pageview information to the public, is the "Popular Posts" gadget.

Popular Posts identifies from 1 to 10 of the most popular posts in the blog, by comparing Stats pageview counts. Optional parts of the display of each post are a snippet of text, and an ever popular thumbnail photo.

Like many Stats features, blog owners have found imaginative uses for "Popular Posts" - and overlook the limitations of the gadget. Both the dynamic nature of Stats, and the timing of the various pageview count recalculations, create confusion, when Popular Posts is examined.
