Google has started a new procedure to redirect your blogspot.com blog to country-specific. This has been started with India and Australia in the first list and blogspot.com will change to blogspot.in and like that.

Why you are seeing a URL change to blogspot.in or blogspot.au

In the coming days more countries will be added to “ccTLD” [Country-Code Top Level Domain] list. In this policy a blog’s URL will redirected on the basis of visitor country. For example, if you're in India and viewing http://travel4cool.blogspot.com, you may be redirected to http://[travel4cool].blogspot.in. A ccTLD will be redirected to the country of the visitor’s current position.

As per the Google update more ccTLD’s will be added in the coming weeks for more countries.

Cause for Introduction of ccTLD

Countries like India and China were requesting more control over the free expression and public articles. They need regularization for the free publishing in the Internet and need the removal of unauthorized materials on the authoritative request. 

The localized domains will enable the domain publishers to control the publishing for a specific country and remove the content required by the local law. The migration to ccTLD has provided flexibility in the promotion of free publishing while staying with local laws. 

The ccTLD migration enabled the content removals on specific country basis and has limited the impact to small number of visitors of the specific country. The other users around the world will see the normal contents in the http://googleposted.blogspot.com and this ensures that content removal will effect only in the specific ccTLD.

Search engine optimization effects

Google has rewritten their search engine algorithm to cope with this new requirement and it may negatively affect your blog’s search engine ranking. The possible posting of duplicate Blogspot content on different domains is not recommended. Google is trying to find new ways to minimize the impact this transition.

Readers of blog can visit a specific Blogspot by entering “NCR” formatted URL in the browser and will show the original blog in the U.S. English whether you are in Australia, India, or Germany

For example: http://incashplus.blogspot.com/ncr from a specific country like India or Australia will always display the U.S. English version of the blog.

This NCR URL’s will prevent blog redirection and will stay in the requested domain. The special NCR URL works in all web browsers and all Operating Systems.

This new transition may take some time to get the real effect though Google is working on Blogspot servers for the change.
