What's The Canonical URL Of My Blog?

This blog is (for those of you not familiar with it) "The Real Blogger Status".

The URL of this blog is currently "http://blogging.nitecruzr.net". As long as I publish the blog properly (as "blogging.nitecruzr.net"), I am allowed to advertise the blog using any combination of lower case and upper case letters, that I like. This blog can be accessed as "blogging.nitecruzr.net", "Blogging.Nitecruzr.Net", or even "BlOgGiNg.nitecruzr.net". We say that Blogger URLs are case insensitive.

Even with my readers allowed to use any combination of lower and uppercase letters, to access this blog, I don't want the search engines to index (and determine page rank) my blog using the exact URLs, as typed by each different reader. Even with this blog being addressed as "blogging.nitecruzr.net", "Blogging.Nitecruzr.Net", or even "BlOgGiNg.nitecruzr.net", the search engines index this blog as "blogging.nitecruzr.net".

To help this happen, Blogger uses the "canonical" tag, in the blog header.

The "canonical" tag is not unique to Google.

The "canonical" tag is a cooperative standard.

It was developed as a standard in 2009, jointly, by Google, Microsoft, and Yahoo.

Every Blogger blog, which has a standard and up to date header, contains a "canonical" tag.

A Blogger "canonical" tag is used to convert the blog URL to lowercase characters.

The "canonical" tag provides the base URL of the blog, in all lower case letters, so the search engines know how to ignore various syntax variations.


All links are indexed under one unified URL, providing better SERP positioning, and more search engine generated traffic.

Look at the source for this blog home page, in the header. Note that you have to look at the online "source code" - not at the raw HTML, using the Template Editor!

Here's an excerpt of the header for this blog, with a few line breaks added - and some lines removed - to make it more readable.

<head>
<meta content='IE=EmulateIE7' http-equiv='X-UA-Compatible'/>
<meta content='width=1100' name='viewport'/>

...

<link href='http://blogging.nitecruzr.net/favicon.ico'
rel='icon' type='image/x-icon'/>
<link href='http://blogging.nitecruzr.net/' rel='canonical'/>
<link rel="alternate" type="application/atom+xml"
title="The Real Blogger Status - Atom"
href="http://blogging.nitecruzr.net/feeds/posts/default" />
<link rel="alternate" type="application/rss+xml"
title="The Real Blogger Status - RSS"
href="http://blogging.nitecruzr.net/feeds/posts/default?alt=rss" />
<link rel="service.post" type="application/atom+xml"
title="The Real Blogger Status - Atom"
href="http://www.blogger.com/feeds/24069595/posts/default" />
<link rel="EditURI" type="application/rsd+xml"
title="RSD" href="http://www.blogger.com/rsd.g?blogID=24069595" />
<link rel="openid.server" href="http://www.blogger.com/openid-server.g" />

There it is.

<link href='http://blogging.nitecruzr.net/' rel='canonical'/>

My test blog, "Nitecruzr New Template Laboratory", is still published to "nitecruzrtestnew.blogspot.com".

<link href='http://nitecruzrtestnew.blogspot.com/' rel='canonical'/>

The "canonical" tag is essential for the country code domains.

These records are essential, for blogs published to "blogspot.com", now that Blogger is aliasing our blogs using country code TLD URLs.

My test blog, for instance, published to "nitecruzrtestnew.blogspot.com", will be accessed as "nitecruzrtestnew.blogspot.in" in India - but the search engines, which observe the Canonical tag, will still index any links as "nitecruzrtestnew.blogspot.com".

Candhinagar,

If "nitecruzrtestnew.blogspot.com" automatically redirects to "nitecruzrtestnew.blogspot.in", where you are, then you are in India, and country code aliasing is working.

Am I right in thinking that if my Blogger blog includes



I don't need the rel.canonical tag?

Annie,

The canonical tag is part of the standard blog header, so it's not a choice whether to include it.

And you do need it, it allows people to spell the blog name with various capitalisations, and get the same results.

But I don't know what your question was, possibly because you included a character string with "<" and ">" characters, where we now see a blank line?

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.

Free Domain Registration By "UNONIC" Is Fraudulent

Blogger blog owners, like everybody else, like to save money.

Some blog owners prefer to save money when registering a custom domain, for their blogs. We've seen several free domain registration services, providing what is claimed to be a two level Top Level Domain "co.xx" (where "xx" == various country codes).

The latest in this ongoing story appears to be "net.tf" - and 13 other "top level domains".There is also an additional free service offering third-level .tf domains, under the name United Names Organisation. They occupy 14 second-level domains, including .eu.tf, .us.tf, .net.tf, and .edu.tf. They are run by the same company as smartdots.com, and are given away as URL redirections.
