What is international SEO?
International SEO (search engine optimisation) is how you target users across multiple regions and different languages. It's the process of optimising your website so it appears in search engine results pages (SERPs), and helps brands to reach a wider global audience.
With international SEO, you can target different languages and regions by creating localised content and earning backlinks from valuable, relevant websites. It includes creating a content strategy that matches international audiences and their search preferences.
Read on to find out how you can implement international SEO tactics into your brand's content and performance strategy.
1. Carry out market-specific keyword research
Keywords cannot simply be translated from one language into another. Keywords vary vastly between international markets; depending on a user’s location, they may search for the same product as someone in another country but use completely different language and keywords.
You must carry out keyword research for every target market. The most important step is finding the terms your target audience searches for, not simply translating your native market’s keywords. We’d recommend looking at the following key areas when doing market-specific keyword research:
Search intent: Informational, navigational, transactional, commercial
Terminology and phrasing
Local search volumes
Competitor rankings
Semantic keywords

2. Ensure URL structures are correct for all international sites
You must give search engines clear signals about each market your website serves. You can organise your international websites and their URLs by:
Country-code domains: e.g. domain.uk
Subdomains: e.g. uk.domain.com
Subdirectories: e.g. domain.com/uk
It is also vital that each language or regional version has a separate, crawlable URL on your website, rather than relying on dynamically changing content or automatic redirection based on the user’s IP address/browser language, as search engines may not discover every variation.
Your brand could also benefit from strong internal links that let both users and search engines navigate between different international versions. An example would be to create a language selector on your website's footer to make it easier for a user to choose between languages.
3. Implement hreflang for language and regional targeting
In 2011, Google added the hreflang attribute to help search engines understand the intent behind the same webpages in different languages.
The hreflang attribute helps Google understand the relationship between your site’s web pages and which language you’re using on certain pages. It helps search engines determine the most appropriate version of your site to display based on the user's language and region.
Google does not rely solely on hreflang implementations and uses visible, crawlable content to detect languages. Implementation errors can occur in hreflang too, including:
Missing return links between alternative pages
Linking to redirected or broken URLs
Hreflang implementations that conflict with canonical tags
Incorrectly mapped pages
Incorrect language or country codes

4. Be region-specific and localise content
Effective localisation is essential for producing relatable content across all languages. Relevant terminology and knowing the search intent (navigational, informational, commercial or transactional) behind a query can help determine a webpage’s success.
Consider the following aspects when producing content:
Currencies
Dates and addresses
Product names
Delivery information
Metadata
Imagery
Especially when producing blog content, you must identify the topics that matter to each market instead of merely reproducing your content strategy in another language. Look at the problems that a specific audience is encountering as well as the questions they’re asking online. Ultimately, your international strategy should respond to local demand.
5. Build authority in each target market
Your brand’s international site pages need authority and relevance to compete successfully in those markets. Your brand must build links and brand mentions from relevant websites to its international sites to strengthen its local presence.
International SEO isn’t just about translating your existing strategy; it also involves digital PR to establish your brand as a relevant competitor in its field. Building brand authority and securing relevant coverage are key to your brand’s overall success.
Competitor analysis matters too. Analyse the websites that link to businesses already performing well in your international market and build a content strategy that identifies the content that will earn your brand relevant impressions and clicks.
