Running a website in multiple languages or countries.

Not every business needs to worry about international SEO. Here are the situations where it becomes essential:

1. You serve clients in other countries. Like Armando’s BPO company serving US, UK, and Australian clients. Your website needs to signal relevance to searchers in those specific countries.
2. Your target customers speak a different language. Like Yolanda’s travel agency targeting Korean and Japanese tourists. Your content needs to exist in their language.
3. You have (or plan to have) your website in multiple languages. Like Jun, who runs an export business with Filipino and Chinese versions of his site. Without proper setup, Google may show the Chinese version to Filipino searchers and vice versa.
4. You sell products or services to international markets. Like Desiree, who runs an online English tutoring business targeting students in Japan and Vietnam. Her potential students search in Japanese and Vietnamese, not English.
5. You operate separate websites for different countries. Like Chito, who runs a food manufacturing company with separate .ph and .com sites. Without coordination, these sites compete against each other in search results.

If none of these apply to you, international SEO is not something you need to act on right now. But if even one sounds familiar, the rest of this article will save you from some expensive mistakes.

This distinction trips up a lot of business owners, so let’s make it crystal clear with real examples.

Language targeting

What it means: You want your content shown to people who speak a certain language, regardless of where they are in the world.

Example — Desiree’s tutoring business: Desiree teaches English online to students in Japan and Vietnam. She needs her marketing pages in Japanese and Vietnamese. A Japanese speaker in Tokyo, a Japanese speaker in Los Angeles, and a Japanese speaker in London should all be able to find her Japanese-language pages. That is language targeting — the language matters, not the country.

Country targeting

What it means: You want your content shown to people in a specific country, regardless of what language they speak.

Example — Armando’s BPO company: Armando serves clients in the US, UK, and Australia. All three markets speak English, but the services, pricing, and compliance requirements differ by country. He needs Google to show his US-focused page to American searchers, his UK-focused page to British searchers, and his Australian page to Australian searchers. Same language, different countries. That is country targeting.

Combining both

Example — Yolanda’s travel agency: Yolanda targets Korean tourists (language: Korean, but she also wants to reach them specifically when they are planning trips to the Philippines). She combines language targeting (content in Korean) with geo-relevant content (tours in the Philippines). Her hreflang tag would use ko for Korean language. She does not need to target a specific country because Korean speakers anywhere might book Philippine tours.

The key takeaway: hreflang tags can specify language only (hreflang="ko"), or language plus country (hreflang="en-US", hreflang="en-GB", hreflang="en-AU"). Use language-only when geography does not matter. Use language-plus-country when you have different content for the same language in different countries, like Armando does.

Translation means converting words from one language to another. Localization means adapting your content for a specific market — the culture, the search behavior, the local references, the way people actually talk and search in that language.

The difference is enormous for SEO.

Why straight translation fails

Example — Yolanda’s first attempt: Yolanda used an automated translation tool to convert her English tour descriptions into Korean. The translations were technically correct but read like a textbook. Korean travelers searching for island tours use specific phrases and search patterns that differ completely from English. Yolanda’s translated content did not match any of the keywords Korean users actually type into Google or ask ChatGPT.

Google can detect low-quality auto-translated content. In many cases, it simply chooses not to index it. Even if it does index the content, it will not rank well because the keywords do not match what real users search for.

What localization looks like in practice

For Yolanda’s Korean pages, proper localization would mean:

• Researching what Korean tourists actually search for when planning Philippine trips (specific Korean keywords and phrases)
• Writing content that uses those natural Korean search terms
• Referencing Korean holidays and travel seasons (Chuseok breaks, Korean school vacation periods)
• Including payment methods Korean travelers prefer
• Addressing concerns specific to Korean tourists (visa requirements, direct flights from Seoul or Busan)

This is dramatically different from running English text through a translation tool. Localized content ranks because it matches what real users in that market are searching for.

How AI search changes the calculation

AI search tools like ChatGPT, Perplexity, Gemini, and Copilot are multilingual by nature. When a Japanese student asks ChatGPT in Japanese about online English tutoring from the Philippines, the AI will prefer to cite sources that are written in Japanese and are contextually relevant to a Japanese audience. Desiree’s properly localized Japanese pages have a far better chance of being cited than a machine-translated version.

The investment in proper localization pays dividends in both traditional search and AI search.

Mistake 1: Using flags to represent languages

Many websites use country flags as language selectors. The Brazilian flag for Portuguese, the Spanish flag for Spanish, the American flag for English. This causes problems. Portuguese is spoken in Brazil, Portugal, Mozambique, and other countries. Spanish is spoken in over 20 countries. Using a flag assumes one country owns a language, which alienates users from other countries. Use language names instead: “Português,” “Español,” “English.”

Mistake 2: Automatic redirects based on IP address

Some websites detect a visitor’s location and automatically redirect them to a language version. A visitor from Japan gets automatically sent to the Japanese version. This sounds helpful but causes serious problems. Google’s crawler accesses your site from the US, so it may never see your Japanese pages. Also, travelers and expats get forced to a language they may not want. Instead, show a banner suggesting the local version but let users choose.

Mistake 3: Forgetting the x-default hreflang

The x-default hreflang tag tells Google which page to show when none of your language or country versions match the searcher. Without it, Google guesses. Jun should set his Filipino homepage as the x-default so that searchers from countries he does not specifically target see the Filipino version by default.

Mistake 4: Duplicating content across language versions without hreflang

If Armando creates separate pages for the US, UK, and Australian markets but all three are in English with similar content and no hreflang tags, Google sees three duplicate pages. It will pick one to show and suppress the other two. Hreflang tags tell Google these are intentionally separate versions for different audiences, not duplicate content.

Mistake 5: Machine-translating without review

We covered this in the localization section, but it bears repeating. Running your website through Google Translate or any automated tool without human review produces content that Google may refuse to index and that AI systems will not cite. If you cannot afford professional translation for every page, start with your most important pages — homepage, main service pages, and contact page — and expand from there.

Mistake 6: Ignoring local search engines

Google is not the primary search engine everywhere. In China, Baidu dominates. In Japan, Yahoo Japan still holds significant market share (though it uses Google’s search technology). In South Korea, Naver is a major player. If Jun is targeting the Chinese market, he needs to consider Baidu’s requirements alongside Google’s. Desiree targeting Japan should ensure her site works well in Yahoo Japan as well.

1. Decide whether you need language targeting, country targeting, or both. Review the Armando, Yolanda, Jun, Desiree, and Chito examples above to identify which scenario matches your business.
2. Choose your URL structure. Subdirectories are the safest choice for most small businesses. Only consider ccTLDs if you have the budget and team to maintain completely separate sites.
3. Invest in proper localization, not just translation. Start with your homepage, main service pages, and contact page. Hire native speakers or professional translators who understand your target market.
4. Implement hreflang tags on every page that has a language or country variant. If you use WordPress with WPML or Polylang, this is handled for you. For custom sites, work with your developer.
5. Include an x-default hreflang tag pointing to your main/default language version.
6. Set up Google Search Console for international targeting. Verify your hreflang implementation and monitor country-level performance.
7. Avoid the common mistakes listed above: no flag-based language selectors, no automatic IP redirects, no machine translation without human review.

International SEO

The practice of optimizing your website so that search engines can identify which countries and languages your content is intended for, and serve the correct version to each user.

Hreflang tag

A piece of HTML code that tells search engines which language (and optionally which country) a specific page is written for. It also links together all the different language versions of the same page.

Localization

Adapting content for a specific market beyond simple translation. Includes adjusting keywords, cultural references, currencies, date formats, and addressing market-specific concerns.

ccTLD (country-code top-level domain)

A domain extension that identifies a specific country. Examples include .ph (Philippines), .jp (Japan), .au (Australia), .uk (United Kingdom). These send strong country-targeting signals to search engines.

Subdirectory

A folder within your main domain used to organize content by language or country. Example: yoursite.com/ja/ for Japanese content. Also called a subfolder.

x-default

A special hreflang value that specifies the default page to show when no other language or country version matches the user. Usually set to your primary language version.

Canonicalization

The process of telling search engines which version of a page is the “official” one when similar or duplicate versions exist. In international SEO, each language version has its own canonical URL pointing to itself.
