Website Localization: How It Works and Best Practices 

Most SaaS companies have significant traffic from non-English markets, but low conversion rates. 

Someone may like your product and feel like it’s exactly what they need. Upon ‌closer inspection, they realize they might have a hard time getting the customer support they need because of the language gap. 

Maybe they don’t like seeing prices in a different currency, or some wording feels awkward when they try to translate your content to better understand it.

There’s one missing piece that’s hurting your conversions here: localization. Not just translation. Because localization doesn’t stop there. It adapts every part of the content, the UX, and the visuals, so that it resonates with people in different regions. 

This post will help you understand what localization is, how it works, and the best practices that separate scalable programs from one-off projects.

What is website localization?

There’s a common misconception that localization is just translation. And while translation is a big part of it, it’s not the whole process.

Translation changes the language. Website localization adapts the full website experience for a specific market, including content, design, UX, SEO, navigation, forms, CTAs, pricing, imagery, and metadata.

It’s also different from internationalization. Internationalization (i18n) is the technical groundwork that makes a website easier to adapt across languages and regions. Localization is the market-facing work that turns that foundation into an experience that feels relevant, trustworthy, and usable for a specific audience.

For SaaS teams, that distinction matters because buyers don’t experience your website as isolated pages. They move from search results to landing pages, from CTAs to forms, from pricing to product messaging. 

If you stop at translating words, the rest of that journey will feel like it was built for another market, and the experience can break before the buyer ever reaches sales.

Why website localization matters for SaaS growth

CSA Research found that 76% of online shoppers prefer buying products from websites in their native language. Not only that, but 40% also say they would never buy from a website in a foreign language.

The reasons behind these statistics usually fall into three areas.

1. SEO

Localized pages rank for in-language queries, bringing in organic traffic. And SEO is a great example of why simple translation isn’t enough. 

A keyword may do extremely well in English. Simply translated, with no adaptation or marketing research, it could become a keyword that nobody looks for.

Localization goes one step further than translation. It looks for variations of the keyword, adapting the strategy around what buyers actually search for in that market.

But traffic is only the first part of the growth case. Once visitors arrive, the localized experience has to help them move forward.

2. Conversion

Localized landing pages are more likely to convert than pages that are only translated. Because simple translation can miss a lot of things. 

• Expressions that make sense in one language but sound weird or mean something completely different in another.
• Prices that may still use the currency from the main market, because translating usually doesn’t involve currency conversions.
• Buttons and navigation menus that look weird because the language expanded and the text doesn’t fit any longer.

And even when the page is understandable, buyers still need to feel confident that the company can support them in their market.

3. Trust

Buyers evaluate in their native language even if they purchase in English.

This is especially important in SaaS, where the buying decision often involves multiple stakeholders. Someone may understand enough English to browse your website, but still feel less confident evaluating pricing, security, implementation, or product details in a second language.

Localization reduces that friction. It helps buyers understand what the product does, how it fits their needs, and whether your company is prepared to support their market.

A localized website signals that you are not just selling internationally. You are ready to create a clear, credible experience for that market.

How website localization works: The core process

At a high level, a localization workflow moves through five stages.

• Audit and prioritize. Before translating anything, understand what you have and where it’s going. Look at analytics and see which countries and regions are already sending you traffic or trial signups. Cross-reference with your pipeline data: where are your deals coming from? This shows you demand beyond traffic, which is critical when making resourcing decisions.
• Prepare. This is all about technical setup. Internationalize your codebase, extract strings, set up Translation Memory so you don’t have to keep translating repeated content, and create a style guide and glossary for language pairs.
• Translate and localize. There’s no one-size-fits-all approach here, but for most teams a combination of machine translation (MT) and human review will be ideal. MT can handle most content well, but human review is still essential for anything customer-facing, brand-sensitive, or technically precise.
• Publish and QA. Seeing the translated content rendered in the actual UI is more important than many realize. Translation may look right in a spreadsheet and still break the layout, truncate in buttons, or just look awkward in context. Look at each page like a user would, to spot any mistakes.
• Optimize. Content and products change, and SEO data for each locale accumulates over time. Treat localized pages as living assets, not archived translations.

Choosing which markets and pages to prioritize first

Where should you start, and which markets and ‌pages should you prioritize? It’s the question that creates the most paralysis, and the answer is usually simpler than you’d expect. Start with revenue signals, not traffic.

Traffic from a market is great. But it doesn’t automatically mean those people are ready to buy. If, for instance, you have 10,000 monthly visits from Japan, but only around five trial signups, while in France, you have around 1,000 visits but 200 trial signups, the French market deserves attention first.

On the page side, prioritize the conversion path before anything else. Top-of-funnel blog posts, for instance, can wait. Localize the pages that are part of the evaluation journey: the product and pricing pages, and the demo request flow, where the decisions happen.

Website localization best practices

You need to do more than translate, that part is clear, but how exactly can you localize a website successfully? There are six best practices to keep in mind.

1. Build a localization workflow, not a one-off project

The biggest mistake we see teams make is treating localization as a campaign, something you do once for a market launch, then set aside. 

Your site changes constantly: new features become available, pricing updates, landing pages get refreshed. Without a workflow that captures and routes those changes for translation automatically, localized pages drift from the source.

A sustainable workflow means content changes don't require a separate project to localize. They get detected, routed, translated, reviewed, and published through a repeatable process that runs in the background. That's the foundation everything else sits on.

2. Localize for the market, not just the language

Spanish for Spain and Spanish for Mexico share a language, but they do not always share the same tone, terminology, trust signals, or buyer expectations. The same is true for Brazilian and European Portuguese, for Mandarin across different regions, and for French across Europe, Canada, and West Africa. 

Treating a language as a monolith where one translation serves all markets where it's spoken, is a shortcut that tends to produce content that feels generic to everyone.

Beyond dialect, markets differ in what they need to see to trust a vendor. Social proof that resonates in the U.S. (logos, G2 ratings) may matter less in markets where relationships and local references carry more weight. If you're investing enough to localize for a market, invest enough to understand what that market actually responds to.

3. Treat SEO as a localization input

A translated page and a localized page are different SEO objects. The phrase your English page ranks for may not be how that concept is searched in German, Japanese, or Brazilian Portuguese. In some cases the direct translation might not even be a phrase people use. 

Building localized pages around English SEO copy that’s been translated, rather than in-language keyword research, means you're optimizing for search behavior that may not exist.

Do keyword research for each target locale before the translation work begins. The findings should inform not just the metadata but the page structure and which topics get emphasis.

Localized pages built on real in-language demand will significantly outperform those that inherit the English page's SEO logic.

4. Maintain a translation memory and glossary

A translation memory stores previously approved translations so they can be reused when the same content appears again. 

A glossary locks down how key terms like your product name, feature names, industry terminology, should appear in each language. Both save time and prevent inconsistency from compounding over time.

5. Use automation to scale

Human review is the quality safeguard, but it should not be the only thing your localization process depends on. Machine translation has improved enough that it's a viable first pass for many content types. 

Customer-facing pages, brand-sensitive copy, and anything in regulated industries warrant human review. Internal documentation or low-traffic support content may not.

The teams that scale localization programs successfully have automated the repetitive operational work: detecting when content changes, routing it for translation, and publishing updates once reviewed. 

That frees human effort for the judgment calls: reviewing MT output, adapting tone for a specific market, catching anything that reads wrong in context. Automation handles volume; people handle nuance.

6. Don't stop at the top of the funnel

One of the most common localization failures is translating the homepage and blog while leaving the trial signup flow, in-app onboarding, and customer support content in English. 

If you've spent the effort to bring someone in through a localized marketing page, dropping them into an English-only product experience undermines the entire investment.

Website localization strategy: building a program that scales

If you want to succeed from the start, you need to understand localization isn’t a marketing project. Treat it instead like a business capability. Something that runs continuously, improves over time, and informs broader decisions about which market to invest in.

A localization program needs cross-functional alignment:

• Marketing owns the content strategy and SEO.
• Product and engineering own the i18n infrastructure and in-app strings.
• Leadership owns the market prioritization decisions.

Otherwise, your website localization strategy ends up fragmented and hard to sustain.

A phased rollout approach is almost always better than trying to localize everything for multiple markets at once. Launch one or two markets, measure performance (organic traffic per locale, conversion rate by market, time-to-publish for new content), and use the data to make the case for expanding.

Proving ROI on a small scale is both less risky and more persuasive internally.

Tooling matters, but it’s a means, not an end. A translation management system that integrates with your CMS or codebase eliminates the copy-paste-export cycle that kills productivity and introduces errors.

Look for tools that support Translation Memory, glossary management, in-context editing, and workflow automation. Those capabilities are what separates a sustainable program from one that relies on heroic, but slow, manual effort.

Common website localization mistakes to avoid

Even the best-thought-out website localization strategies can fall victim to common traps, and most of them are avoidable with the right workflow and tooling in place.

• Machine-translating without review. MT quality has improved dramatically, but publishing its output directly to customer-facing pages is a big risk. Especially when dealing with industry-specific terminology, brand-sensitive copy, or markets where translation errors carry legal risks, human review is still a must.
• Ignoring hreflang. Hreflang tells search engines which version of a page to serve to which audience. Getting it wrong means your localized pages may not rank in the markets they’re intended for, or Google may index the wrong version. 
• Treating all markets equally. The effort required to localize for Canadian French is different than that required for Japanese. The content adaptation needed for the U.S. market is different from the Gulf region. A one-size-fits-all localization strategy produces one-size-fits-none results.
• Localizing the top of the funnel, but not the conversion path. Getting someone to a localized landing page and then dropping them into an English-only trial flow is a common and costly inconsistency.
• Launching once and never updating. Stale localized content erodes trust faster than no localization. A French buyer who sees a product feature that’s been updated in one language but not in French, will think twice before purchasing.

The teams that build effective website localization programs share one trait: they treat it as an ongoing capability, not a periodic project. That means infrastructure, workflow, cross-functional ownership, and a feedback loop between localization investment and market performance.
