In their ongoing quest to provide their users with the most relevant search results possible, the major search engines are designed to search results that are tailored to the geographic location of the user. This means that someone searching for a particular keyword phrase from inside Australia will most likely see a different set of results compared with someone searching the same keyword from inside New Zealand.
Given that users in different countries will see a different set of search results for the same keyword search, it's vital that businesses looking to target customers across multiple countries have a robust international search engine optimisation (SEO) strategy in place. For example, let's say you have a range of products that you sell online in New Zealand and you decide that you want to break into the UK market. To do so you'll want to make sure that your website (and hence your products) can be found online by prospective customers searching for your products in the UK (e.g. via Google.co.uk), as well as prospective customers searching from inside New Zealand (e.g via Google.co.nz).
So, what options are available to you if you're embarking on an international SEO campaign? First it's important to understand how search engines decide which results to show users from each different geographic location.
How do search engines determine which results to show to searchers from different countries?
Understanding the impact the following factors can have on your international SEO efforts is critical to achieving online visibility across multiple countries.
What's the best strategy for achieving international SEO success?
Creating a successful international SEO strategy begins with determining the best approach. Unfortunately there's no 'best' solution, and the approach you do take will often be dependant on your company's structure, resources and requirements.
While Approach 1 is probably the most ideal solution overall, Approach 2 and 3 are best if you don't have the resources to manage building and maintaining two separate websites.
For a review of the pros and cons of each approach take a look at the following post courtesy of Google titled working with multi-regional websites.
International SEO and how to handle duplicate content
When targeting several countries that share the same language there is the potential for duplication of content across each website. Using local country ccTLDs is good way to minimise the risk of content duplication, as is creating unique content tailored for the geographic audience you are targeting. Google’s Webmaster Tools settings should also be used on each domain (or subdomain or subfolder, depending on your approach) to show Google which site is targeted to which country.
Conclusion
When it comes to international SEO there are a number of options available to you (subdomains/subfolders/top level domains, target country hosting etc). Every situation is different and as such we advise a measured approach that considers all of the factors. As with all things SEO-related there’s no one size fits all solution - you have to find the best mix for your circumstances and goals.
