How to do SEO for multiple countries

International SEO requires three core decisions before you execute anything: which countries you're targeting, what language variations matter, and whether you'll use subdomains, subdirectories, or separate domains. Most agencies recommend subdirectories (example.com/de/ for Germany) because they consolidate domain authority better than subdomains (de.example.com) or separate domains entirely. Separate domains make sense only when you're truly localizing for different markets with different businesses or brand names. Within subdirectories, use hreflang tags to signal to Google which content is for which country and language combination. This prevents cannibalization where Google gets confused about whether to rank your UK English version or US English version for a search query.

Your technical foundation matters as much as content. Set the correct country targeting in Google Search Console—you'll do this per property (so if you use subdirectories, you target at the root domain level and let hreflang do the granular work). Make sure your site structure is consistent across markets; a user visiting the German site should have the same navigation and UX as the English site, just translated. Load times matter more for international sites because you're serving content across regions, so configure a CDN to cache content closer to your users. XML sitemaps should include all language versions with proper hreflang annotations, and your robots.txt shouldn't block any country-specific content.

Beyond technical setup, remember that SEO agencies often underestimate localization beyond translation. Search intent varies by market. A German user searching for "SEO Agentur" has different expectations than an English speaker searching "SEO agency"—they may want local results, expect different price points, or use different terminology within the industry. Research local search behavior, check what competitors rank in each market, and adapt your content strategy accordingly. Build backlinks within each target country because local links carry more weight for local search. If you're managing this across multiple markets, create a keyword research template that includes local search volume data, local competitor analysis, and market-specific intent notes. This prevents the common mistake of just translating keywords without understanding what people in each market actually search for and why.
