Google does country-specific redirection for selective censorship – that means they can easily censor or block a blog post, or other entire blog site, in one country but still serve that page in other geographic regions. Blog redirection only occurs if you are on a blogspot domain and not if your Blogger blog is on a custom domain.
My traffic logs suggest that country-specific redirection in Blogger is live in at least 15 countries. They are India [blogspot.in], Australia [blogspot.com.au], UK [blogspot.co.uk], Japan [blogspot.jp], New Zealand [blogspot.co.nz], Canada [blogspot.ca], Germany [blogspot.de], Italy [blogspot.it], France [blogspot.fr], Sweden [blogspot.se], Spain [blogspot.com.es], Portugal [blogspot.pt], Brazil [blogspot.com.br], Argentina [blogspot.com.ar], Mexico [blogspot.mx]
Prevent Blogger from Redirecting to Country-Specific Domains
This country based URL redirection is likely to impact your Blogger blogs in a not so positive manner. For example:
The social stats – like your Facebook Likes, Google +1s and Tweet counts – for your blog posts may be reduced as the URLs for the same blog post will be different for different visitors.
You will have a similar problem if you are using an external commenting platform like Disqus or Facebook Comments because the blog URLs will be different even when the underlying page is the same.
Also, if canonicalization isn’t implemented properly, it may cost you some Google juice as external websites may link to your country-specific pages.
Some users have reported a dip in Google AdSense earnings when pages are served through country-specific domains.
If you are not happy with the idea of Blogger redirecting your blog to a different URL, you can add the following piece of code to your Blogger template and it will always serve the .com address to your visitors irrespective of their geographic location.
Go to your blog inside the Blogger Dashboard and choose Template. Then click the “Edit HTML” button followed by “Proceed.” Next, copy-paste the following code into the template after the <head> tag.
Click the Save Template button and now your Blogger Blog will always serve with the blogspot.com URL.
