How to start a multilingual site?

You would have always thought of creating one or several sites in different languages for the people of different countries . Let's say you want to start a technology site in Europe, and you want to offer your content to Japanese, German, and Spanish speakers. The major factors to keep in mind are site structure, geographic as well as language targeting, and content organization.

Site structureThe first thing you'll want to consider is if it makes sense for you to buy country-specific top-level domains (TLD) for all the countries you plan to serve. So your domains might be ilovebackpacking.co.uk, ichlieberucksackreisen.de, and irdemochilero.es.es. This option is beneficial if you want to target the countries that each TLD is associated with, a method known as geo targeting. Note that this is different from language targeting, which we will get into a little more later. Let's say your German content is specifically for users from Germany and not as relevant for German-speaking users in Austria or Switzerland. In this case, you'd want to register a domain on the .de TLD. German users will identify your site as a local one they are more likely to trust. On the other hand, it can be pretty expensive to buy domains on the country-specific TLDs, and it's more of a pain to update and maintain multiple domains. So if your time and resources are limited, consider buying one non-country-specific domain, which hosts all the different versions of your website. In this case, we recommend either of these two options:

1. Put the content of every language in a different subdomain. For our example, you would haveen.example.com, de.example.com, and es.example.com.
2. Put the content of every language in a different subdirectory. This is easier to handle when updating and maintaining your site. For our example, you would have example.com/en/, example.com/de/, andexample.com/es/.

Matt Cutts wrote a substantial post on subdirectories and subdomains, which may help you decide which option to go with.

Geographic targeting vs. Language targetingAs mentioned above, if your content is especially targeted towards a particular region in the world, you can use the Set Geographic Target tool in Webmaster Tools. It allows you to set different geographic targets for different subdirectories or subdomains (e.g., /de/ for Germany).

If you want to reach all speakers of a particular language around the world, you probably don't want to limit yourself to a specific geographic location. This is known as language targeting, and in this case, you don't want to use the geographic target tool.

Content organizationThe same content in different languages is not considered duplicate content. Just make sure you keep things organized. If you follow one of the site structure recommendations mentioned above, this should be pretty straightforward. Avoid mixing languages on each page, as this may confuse Googlebot as well as your users. Keep navigation and content in the same language on each page.

If you want to check how many of your pages are recognized in a certain language, you can perform a language-specific site search. For example, if you go to google.de and do a site search on google.com, choose the option below the search box to only display German results.
