When expanding into international markets, most teams hit the same wall: language. You can’t win search or earn trust in a market you don’t speak to. Doing international SEO for 100 languages well means three things at once: a URL structure that keeps your authority in one place, hreflang markup that tells search engines which version to serve, and content localized rather than literally translated.
Translated pages routinely outperform generic ones in organic search. A 2021 study found that multilingual websites using region-specific keyword strategies saw a 47% increase in organic traffic from target markets.
Take Canva, for example. With over 65% of its users outside English-speaking markets, Canva’s international strategy is deeply rooted in translating organic pages. Its “/create” pages—focused on helping users design resumes, logos, and other key assets—are translated into dozens of languages, generating an additional 15.5 million organic visits per month.
But scaling international SEO is complex, costly, and difficult to sustain. Many fast-moving teams push it down the roadmap—not because it’s unimportant, but because traditional translation workflows don’t scale.
That’s why we’re introducing daydream’s international SEO feature—designed to help growth teams create and manage high-performance, language-specific pages at scale.
📈 International SEO is essential for organic growth
International SEO isn’t just about translating words—it’s about visibility, conversion, and trust. When customers experience your brand in their language, they’re significantly more likely to convert:
- 40% of consumers won’t buy from websites in languages other than their own.
- 68% would switch brands if another offered native-language support.
- 57% consider it a bias when brands don’t provide multilingual experiences.
❗ But international SEO has been challenging to scale
Traditional translation workflows are labor-intensive, expensive, and largely unscalable.
Here’s why:
- High-quality translation isn’t cheap. Depending on the language pair and subject matter, translation can cost between $0.10 to $0.25 per word. Large websites with thousands of pages can quickly rack up translation costs nearing tens of thousands of dollars.
- Managing multiple vendors is slow and operationally burdensome. Operational overhead adds another layer of complexity for in-house teams who must manage translation vendors, coordinate feedback loops, and ensure pages are kept up to date across multiple markets. Even companies with dedicated localization teams, like Canva, rely on vendor networks and localization specialists to handle volume. It works, but it’s slow and prohibitively expensive for many companies.
- International SEO requires more than simple translation. People expect culturally adapted content, not just literal translations. Take Airbnb, for example. The hospitality platform started out as an English-only experience, but later invested heavily in localization to ensure the platform accounted for local payment methods, currencies, and culturally relevant imagery. This investment paid off. Airbnb is now recognized as a global hospitality leader. Historically, achieving this level of cultural nuance was challenging on top of the manual translation work.
✍🏻 AI is rewriting the international SEO playbook
Today’s large language models (LLMs) don’t just translate—they interpret. They understand tone, structure, semantics, and cultural nuance. That means AI can adapt content for local markets in ways that go far beyond literal word-for-word translation. The result? Content that reads naturally, ranks effectively, and resonates deeply with local audiences.
AI also removes the need to choose between quality and scale. What once took weeks—briefing agencies, reviewing drafts, coordinating feedback—now happens in seconds. And because AI (such as daydream’s architecture) can be trained on your brand voice, terminology, and style guidelines, the output stays consistent across every market.
Take OpenArt, for example. daydream worked with OpenArt to translate 1,200 SEO pages from English to 11 languages. Our AI-driven workflows allowed OpenArt to publish 10,000+ translated pages in just three months, shipping a new language in less than two weeks on average. Below is an example of OpenArt’s “AI Pokemon Generator” page in English and French.
Even more importantly for growth teams: AI enables international SEO to become a continuous, always-on function, not a one-off campaign effort. New content, site updates, and product pages can all be translated instantly in lockstep with your broader content strategy.
This shift doesn’t just reduce overhead. It transforms international SEO and localization from a cost center into a growth multiplier—fueling better SEO, faster market entry, and higher conversion in every region you serve.
Translation is half the job: pick a URL structure before you pick a language
Before your first translated page ships, you have to decide where those pages live. Every ranking guide on this topic treats it as the first technical decision, and they agree on the answer. Contentful, whose author ran SEO for Nike EMEA across 26 ecommerce experiences in nine languages, lays out the three options like this:
Configuration | Example | What it does to SEO equity | Verdict |
|---|---|---|---|
ccTLD | example.de | Good for ranking in one country, but no inherent connection to your native property, so no shared SEO benefit | No. Prohibitive for sharing equity, and costly to scale |
Subdomain | de.example.com | Each subdomain is typically treated as a unique web property from the root domain, which splits the benefit | No. Limiting in terms of sharing SEO equity |
Subfolder | example.com/de/ | Consolidates any and all earned SEO equity at the root domain, and locale is simple to add | Yes. The gold standard, and easily adaptable |
Source: Contentful, Multilingual SEO best practices. Acolad reaches the same conclusion, describing ccTLD as best for market-specific branding but costly to scale, subdomains as flexible but weaker at authority sharing, and subdirectories as recommended for SEO consolidation.
Whatever you pick, avoid URL parameters for language. And do not ship the same content under several locale URLs. If a page for Ireland, Canada, and Australia carries identical text, you have made three duplicate pages rather than three markets.
The structure decision compounds. At 100 languages, a subfolder site is one domain earning links in every market. A ccTLD site is 100 separate domains each starting from zero.
hreflang: the markup that decides which language version gets served
hreflang is a link attribute designed by Google that specifies the language of a page, and optionally its geographic target. Language codes use ISO 639-1 lowercase, region codes use ISO 3166-1 Alpha 2 uppercase, joined by a hyphen: en-GB for British English, en-US for American English. It sits alongside the HTML lang attribute, which declares the language of the page itself.
A minimal two-language annotation uses three link elements: one for English, one for Spanish, and one x-default.
The x-default value names the version to serve in markets where you have no localized page. Without it, a searcher in a market you have not translated for gets whatever the engine guesses.
You have three places to put the annotations: the head of the page, the XML sitemap, or the HTTP header. The header option is for non-HTML files. At 100 languages, the sitemap route is usually the only one that stays maintainable, because every page needs a reciprocal entry for every other language version.
Getting it wrong is not cosmetic:
If hreflang is missing or wrong | What happens |
|---|---|
No annotation at all | Duplicate content penalties from search engines |
Language variants left unlinked | Cannibalization: your own content competes against itself |
Wrong or partial mapping | Incorrect content served in the localized engine, such as U.S. English on Google.co.uk |

Note what hreflang does not do. Google has stated it does not use the HTML lang attribute or hreflang markup to determine the language of a page. It uses its own algorithm for that. hreflang is how you match the right localized content to the right localized search engine, which is a different job.
Scale is the reason most teams get this wrong. Contentful reports that the original Nike implementation took nine months to plan, execute, and deploy across the global property. Generating the annotations programmatically from your translation pipeline is what turns that into a deploy step.

Frequently Asked Questions
Should I use subdomains or subfolders for translated pages?
Subfolders, such as example.com/de/. They consolidate every bit of earned SEO equity at the root domain and are simple to extend with a locale. Subdomains get treated as a separate web property from the root domain, which splits the benefit, and ccTLDs carry no inherent connection to your native property at all.
What does the x-default hreflang value do?
It names the version of your site to serve in markets where you have no localized page. If you have not translated for New Zealand, x-default tells search engines which version to return on google.co.nz.
Where do hreflang annotations go?
Three options: the head of the page, the XML sitemap, or the HTTP header. The header method is for non-HTML files. At high language counts the sitemap is usually the only maintainable route, because every page needs a reciprocal entry for every other language version.
What happens if I skip hreflang?
Three things, per Contentful: duplicate content penalties from search engines, cannibalization where your own content competes against itself, and the wrong localized content served in the wrong engine, such as U.S. English appearing on Google UK.
Can I just translate my existing keywords?
No. Keyword research has to be localized rather than translated, because users search differently in every market even for the same product. Literal keyword translation is the most common reason a technically correct multilingual site still fails to rank.
How long does it take to launch a new language?
With traditional vendor workflows, weeks to months per market. daydream translated 1,200 SEO pages into 11 languages for OpenArt and published 10,000+ pages in three months, shipping a new language in under two weeks on average.
