Google Blogger Platform free blogger.com recently [30th Jan/2012]has changed few technical policies which brings some issues for that services users in posting tracking etc.Their specific changes that Blogger has started using Country Specific URLs and you might have already seen these if you are from India or else where except USA.If you are from India try visiting any BlogSpot URL and you will be redirected to the country code Top Level Domain (ccTLD).For example if you visit any page on http://bloggerztech.blogspot.com from India, you will be redirected to the country specific page http://bloggerztech.blogspot.in . Similarly if you visit any other ccTLDs from India,you will be redirected to the Indian TLD.eg: http://bloggerztech.blogspot.com.au (Australian TLD) will redirect to the Indian TLD.
Blogger.com has made a help page entry describing why they have made this change.You can read that at Blogger Help
Why This Change?
This change was specifically made to enable countrywise censorship.By utilizing ccTLDs, content removals can be managed on a per country basis,which will limit their impact to the smallest number of readers.Content removed due to a specific country’s law will only be removed from the relevant ccTLD.”
Who is affected by this Change?
Everyone Blogger user who doesn’t have a custom domain name(but has readers across the globe) irrespective of the country you are from is affected by this change. Right now it seems like the change has been rolled out only in India. So when an Indian user visits your blog, he will be redirected to the .in TLD. using a 302 redirect.
What should I do Now ?
The first thing that you have to do is to make sure that you are using Canonical tag on your blog Pages. This should be there by default in all templates unless you hacked the template and removed some code from there.
Make sure that the following line is there in your Blog Template
This tag will render the canonical tag for you. If you don’t want to use this tag for some reason,then add the following line to the head section of your template
What does the Canonical Tag do ?
The Canonical tag specifies the actual location of the page.Even if you are viewing a blogspot.in page,the canonical tag will let the search engines know where the actual page is located(the blogspot.com version)
If you don’t have the canonical tag on your pages,you might get into trouble on search engines which might index different country specific pages of your Blog. Your Social Counters(Facebook Like Button, Google Plus One button etc) will show the wrong count and will allow users to share different country specific versions of your Page. Adding the Canonical tag will ensure that the same blogspot.com page gets shared on social networks and so the counters will display the same count irrespective of the country the visitor is from.
Dynamic View Templates
Dynamic View Templates does n’t render the canonical tag(when I am writing this post). Hence non-custom domain blogs which use Dynamic View Templates will face the issues that I have mentioned above.I have reported this to the Bloggers and hope this will soon be resolved.
Custom Domain Blogs will not be affected by this change.
No Country Redirect (NCR)
If you want to temporarily prevent Blogger from doing a country specific redirect while viewing a blogspot blog, then you can use the NCR option.
Examples : http://bloggerztech.blogspot.com/ncr will give you the .com version without redirecting to your ccTLD
