Search engine optimization (SEO) is crucial for driving organic traffic to websites and boosting visibility. However, with global internet usage rising and opportunities to tap international audiences, multilingual SEO strategies are becoming increasingly important. Businesses that adapt and localize content for different linguistic markets stand to gain more traffic, leads, and sales compared to single-language sites.
This definitive guide covers everything you need to know about multilingual SEO in 2023 – from understanding user behavior across languages, optimizing website structure, creating localized content at scale, building links, leveraging social, tracking performance, and more. With the right strategy, your business can successfully navigate the complexities of the global digital landscape.
Why Multilingual SEO Matters
Multilingual SEO refers to optimizing website content for search engines and users in different languages beyond just English. It enables businesses to adapt branding, messaging, products, and overall user experience for international audiences.
Here are some key reasons why multilingual SEO should be a priority:
- Reach more customers globally: Over 58% of online content is now in languages other than English. Targeting multiple languages allows businesses to tap into broader demand.
- Drive more qualified organic traffic: Ranking high on local search engines like Google.de or Baidu allows you to capture audience interest in ways single English sites can’t.
- Boost brand awareness and conversions: Consumers are much more likely to engage with relatable, culturally-relevant content in their native languages. This builds trust, brand recognition and ultimately conversions.
In fact, according to Common Sense Advisory, 42% of consumers spend more money online when content is available in their native languages. The potential impact of multilingual SEO on revenue is clearly substantial.
The Global Digital Landscape
To develop an effective multilingual SEO strategy, you first need to understand key global search engine and internet usage trends.
As of 2022, there were over 5 billion internet users worldwide, up from under 900 million in 2005. Much of this growth is being propelled by emerging markets like APAC, Latin America, and even Africa. India alone was expected to add over 300 million new internet users from 2020-2023.
More importantly, the linguistic profile of the internet is changing dramatically:
- Chinese native speakers make up close to 20% of global internet users. Most of them engage primarily with local sites like Baidu rather than Google.
- There are now over 746 million Spanish internet users – second only to English in popularity online. The Hispanic market is only continuing to grow at a rapid pace.
- Major European languages like French, German and Portuguese all have over 100 million internet users each. Russian and Arabic speaking populations online aren’t far behind either.
Opportunities clearly abound for businesses willing to create multilingual experiences. However, understanding nuances around cultural values, purchasing power, internet infrastructure, and platforms used is key to success.
For example, leading games publisher Activision Blizzard localized Call of Duty for Arabic internet users. This triggered a 200% increase in daily active users from the region, fueling their rise as a top franchise.
Why Invest in Multilingual SEO?
Given the resources required, is pursuing multilingual SEO actually worthwhile though? What’s the tangible business case around ROI?
The right multilingual strategy coupled with effective localization can provide:
1. Increased Site Traffic
By targeting under-served foreign language search queries, sites can rapidly increase visitors and gain market share abroad. Fashion e-commerce site ASOS saw a 145% rise in overall visits after adapting a multilingual SEO strategy focused on French and German speaking markets.
2. Higher Conversions Rates
According to research by SmartLing, visitors are 4.5x more likely to convert when content is available in their native language. Even basic translation alone can drive big gains, with a 3x uplift converting English to Spanish sites.
3. Bigger Basket Size & Order Values
Providing the right multilingual purchase experience doesn’t just increase conversions – it also leads visitors to buy more per order. Global beauty brand FreshCosmetics increased order values by 22% on their Spanish site version.
4. Stronger Keyword Rankings
Targeting underserved long-tail, geo-focused keywords in other languages allows sites to quickly outrank established domestic-only competitors abroad.
5. Faster International Expansion
Optimizing for multilingual experiences accelerates global growth by allowing businesses to cost-effectively validate demand in new overseas markets before committing major SG&A investments.
While getting translation and localization right requires upfront effort, evidence clearly shows this pays off tremendously. Most brands see their multilingual sites account for 50-80% of total traffic within a couple years.
Core Elements of Multilingual SEO
Now that the benefits are clear, what are the key focus areas for multilingual SEO success?
Keyword Localization
Adapting your content and keyword strategy to align with foreign language search behavior is crucial.
While some terms like branded product names can work globally, translation alone usually isn’t enough. Different cultural contexts require localization of concepts. Keyword tools like Google Keyword Planner, Soovle, and SemRush help uncover country-specific high-value target keywords.
You’ll likely identify many new hyper-relevant long-tail keywords that English sites miss out on targeting. Adapt your content accordingly focusing on importance over pure word count.
Don’t forget voice search optimization either. Over 55% of Chinese users and 40% of Americans already engage via voice – often using more natural, long-form queries.
Local Search Optimization
Understanding location-based SERP features is equally important for multilingual keyword strategy and conversions success.
Google provides locally adapted experiences in over 150 countries tailored to what people search for and expect to see where they live. This ranges from hotel/restaurant information in Argentina to product inventory visibility in Germany to emphasis on mobile experiences in APAC.
Ensure local business details like addresses, store hours and contact info are correct and consistent across directories and sites. Actively encourage customer reviews along with check-ins for Google My Business and other profiles. User-generated content builds local trust and relevance signals.
In some markets like India and Brazil, Facebook and Instagram are used more commonly than Google Maps to discover local brands. Maintaining an active, optimized presence on the right platforms is key.
Website Structure Options
When launching multilingual sites, businesses have a few options on how to structure URLs and development:
1. ccTLD Extensions
Using country code top level domain (ccTLD) extensions like .DE or .CN allows for localization credibility and SEO signals. However, this can add domain management complexity long-term. Shared gTLDs using .COM suffixes simplify this at scale.
2. Subdomains
Separating languages across subdomains (en.brand.com, jp.brand.com etc.) avoids duplicate content issues. This works well for distinctly positioned site experiences. However, interlinking content and sharing signals cross-domains provides some technical challenges.
3. Subdirectories
Housing languages within subdirectories (brand.com/en/, brand.com/de/ etc.) of a root domain is a popular, SEO-friendly approach. This facilitates content interlinking, and allows for easy promotion of root domain authority signals across all languages.
In general, subdirectories are preferable from an optimization standpoint as they balance technical needs and user experience for multilingual sites.
Localization Not Just Translation
To engage international audiences, businesses must move beyond machine translation to invest in expert localization services. This allows you to:
- Adapt branding appropriately (logos, slogans, colors etc.)
- Incorporate local cultural references, norms and imagery
- Use regional vocabulary and terminology suited for the target market
According to language services provider One Hour Translation:
“Human translation achieves much greater local relevancy than any automated tool, improving engagement 5x on average.”
Proper localization also means adjusting UI elements, currencies, shipping details, payment methods, taxes and more based on the region.
Review forms and contact pages to simplify and reduce required fields for faster conversions abroad. Remember that North American assumptions around address formats or credit card penetration rarely hold true overseas.
Continually A/B test messaging, offers, images and experiences across languages to determine what resonates best with foreign audiences. Global ecommerce leader NeedWant saw conversion lift simply by experimenting with smaller changes to promo banner colors for Spanish vs English shoppers.
Technical SEO Best Practices
Adapting page markup and site architecture for multilingual success is key too:
hreflang Tags
Indicating to search engines which page version matches the correct language and locale target using <link hreflang="x"> tags avoids duplicate content issues. This helps ensure the right localized page surfaces highest for a user’s query and geography.
URL Mapping
Use 301 redirects or a central URL mapping file to allow non-localized URLs to correctly resolve to the equivalent translated pages on your site. This simplifies link management long-term.
Indexing Controls
Utilize robots.txt settings and meta noindex tags strategically across languages to govern what search engines crawl. This prevents issues with stale automated translations being indexed.
Duplicate Content Mitigation
Avoid going overboard repurposing the same content across multiple languages – search engines will flag sites as potential duplicate content networks. Add language alternate tags and geo-specific title tags to help clarify intent.
Expand Language Support
Beyond textual content, double check that HTML lang attributes, structured data schema markups, image ALT tags and other metadata also match configured languages for better indexing.
Global User Experience Design
Creating seamless, engaging multilingual experiences requires more than just translation – UI/UX choices have a major impact as well.
Carefully consider layout, navigation patterns and information architecture to align with cultural expectations. Adopt mobile-first strategies catering to overseas users increasingly relying on smartphones as their sole internet device.
Ensure imagery, color choices and iconography align with local preferences in each target market. Relying solely on US website perspectives risks confusing or alienating international audiences.
Balance localization with standardization too – maintaining consistent navigation, IA and core features across languages still allows for easier scaling long-term.
Help users immediately identify relevant languages & locales to engage content faster. Auto-detection based on IP geolocation or browser/OS languages paired with easy manual selection on the homepage works well.
Review form UX, required fields and assumed inputs that may not apply abroad. Streamline shopping flows by remembering user selections, maximizing above-the-fold space for key actions, and simplifying inputs.
Deliver locally-optimized mobile and site speed performance for international markets where bandwidth can be limited. Google found that pages taking over 5 seconds to load lost 60% of mobile visitors.
By tailoring experiences thoughtfully around these UX design nuances for each language, conversion rates typically improve significantly.
Understanding Cultural Nuances
What resonates with American consumers from digital experiences and messaging perspective can vary tremendously overseas.
Cultural values around factors like humor, social proof, conformity, uncertainty avoidance and power distance determine how users engage online. Misunderstanding these nuances pose huge user experience risks.
For example, hard-sell messaging very typical from US brands performs dismally across most collectivist Asian cultures. Social proof focused on group affiliations or authority builds credibility far faster there.
Likewise, many informal emoji usages by brands to Western audiences can spark backlashes in Middle East and Indian cultures unaccustomed to such familiarity. Global footwear giant Nike faced criticism trying to directly transplant their English slogan “Just Do It” into colloquial Chinese meaning “do it quickly”.
Work closely with local teams or third-party localization partners well-versed in cultural norms to adapt appropriately across different languages.
Link Building for Multilingual Domains
Links remain one of the strongest SEO signals for rankings regardless of language or market. Creating quality earned, editorial backlinks locally is crucial.
But uniquely for multilingual sites – shared signals passing authority from higher-level root domains to international subdomain / ccTLD properties also matters.
An effective modern link building approach combines:
- Organic local outreach and partnerships
- Culturally-relevant blogger relations
- Foreign social media channels
- Internationalization of existing English links
- Corporate site network optimization
This expands relevance seen by native search engines without over-reliance on riskier tactics.
Hong Kong furniture portal MOSO broke into competitive Chinese rankings leveraging a smart integrated link building strategy tapping Mainland PR agencies, WeChat influencers and overseas forum mentions.
Leveraging Social Media
Many global markets far prefer platforms like WeChat, VK, Line, KakaoTalk for digital engagement over Facebook and Instagram. These channels can drive effective social-powered link building and referral traffic sources:
- Encourage happy customers to engage, tag and review your brand directly driving sales-oriented micro-conversations.
- Formalize these community relationships with user-generated content campaigns that can go viral abroad.
- Work with local creators, bloggers and influencers relevant to your industry. Don’t ignore micro and nano-influencers – engagement rates trump follower counts.
- Hashtags matter and use varies greatly across languages – leverage multilingual social listening to determine what trends best.
- Remember to keep an eye out for translation mishaps or cultural tone-deafness going viral for the wrong reasons!
Insights into multilingual social behavior exists online – seek it out to optimize engagement. Casual conversations in foreign languages drives conversions better than corporate-speak.
Tracking Multilingual SEO Performance
