Automatically redirect users to an international web version without offering the option to select it

[shaownhasan]

While you may want to direct your users to their country or language version, you should not do so automatically using redirects. These redirects can create a confusing and intrusive experience for users who may have come specifically to view content in another language or version of a specific country.

A quick observation on Google
Currently, most Googlebot IPs are still from the US; Google does not crawl from all countries yet (crawlers are mostly from the US and a few other countries). So if we only redirect to the version of the website for those regions, then top benefits of using fusion database Googlebot will always be redirected and will only see some versions of our site, not all.

You are not only redirecting users but also bots.

This is why it is better to not only allow the user to browse whatever international version they have arrived at, but also allow Googlebot to crawl any version instead of redirecting them based on their IP.

Examples
An even worse experience is when the redirect is performed without even allowing users to switch to the international version they wanted to access, by showing a prominent option; this can be experienced on some blogs or news sites, such as Gizmodo.
