FaceBook Is Aggregating BlogSpot CC Aliases

We're seeing a few questions recently, in Blogger Help Forum: Something Is Broken, about FaceBook, and their treatment of Blogger URLs that are subject to country code aliasing.
When I share a post on FaceBook, the URL used for my blog ends with "" instead of "".
Some people in Europe observe a variation.
When I share a post on FaceBook, the URL used for my blog ends with "" instead of "".

We've been observing, for a long time, that FaceBook and other Internet services should start using the canonical tag - and aggregate BlogSpot URLs, that are subject to country code aliasing.

With aggregation done properly, all BlogSpot URLs would be listed as "" - and all Likes, and similar references to a given Blogger blog, would be later counted under the proper "" URL - regardless where a given blog reader gets Internet access.

Apparently, FaceBook is now aggregating BlogSpot URLs - but they are not using the canonical tag in the blog header. For some reason, FaceBook now uses "" - or maybe "" or "" - as the canonical URL for Blogger blogs.

When Blogger first started using country code aliasing, only Google services such as Google Search would reliably aggregate all country code redirected aliases, to "".

Many non Google services did not use canonical aggregation, immediately. Like every other newly developed Internet feature, it takes time for every web service to update their code.

With only Google using canonical aggregation, every Blogger URL subject to country code alias redirection would be shared using the country code alias, as seen by the person doing the sharing. People in France might share a Blogger URL as "", people in India as "", and so on.

People in the USA, of course, would share a Blogger URL as "". The USA, and various other countries, is not subject to country code alias redirection.

FaceBook is now aggregating BlogSpot URLs - but they are not using the canonical tag, in the blog header. For some reason, they are aggregating to "", "", or "" for some or all BlogSpot URLs, shared to their service.

Maybe, FaceBook resolves "" from the various countries - and generates the redirection themselves?

Right now, if you share a BlogSpot URL to FaceBook, the URL will be modified, to "", "", or "". Every Like, and similar activity against that URL, will then be counted under the "", "", or "" alias. This is probably slightly better than having every different URL shared by country code alias - but only slightly better.

Blogger blogs published to custom domains are not subject to URL modification, because custom domain URLs are not subject to country code alias redirection.

When FaceBook corrects their code mistake, any newly shared Blogger URLs will be properly modified according to the canonical tag in the blog header, "" (or any custom domain URL). Quite likely however, any previously shared URLs will remain incorrectly aggregated to "", "", or "" - and any new Likes will continue to be posted to those addresses.

Some Blogger blogs will continue to appear to have at 3 URLs - "", "", "", or "", and any others under which FaceBook was sharing, originally. The search engines may index blog content, accessed from FaceBook shares, as "", "", "", or "".

If this is not acceptable, you may need to report this to FaceBook Support. Please, resist the temptation to install malicious code on your blog, that will later leave you asking for advice on having the blog unlocked, cleaned and reviewed.


I have noticed that too, will that change? Also I am .com but when I log in another country, my Url switches to the country's name ..

Mon ika,

We are hoping that FaceBook Support will learn of their problem - either from this post, or from the millions of member complaints, which they are no doubt getting - and will fix the mistake, pronto.

You are describing the confusion, experienced by some USA citizens, who see the problem, first hand.

If you live in the USA, or another country not subject to Country Code Alias Redirection, you simply don't see the variety of confusion in readers all over the world, in countries subject to the redirection.
Thanks, Chuck!

I used to live in the US, and am no longer there, so my Url changes to the given country, depending on where I am. Weird.
But thank you

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.
