International Link Building

Link building for international SEO follows the same principle as local link building: links from locally relevant domains carry stronger geo-signals than links from globally recognised but geographically neutral sources. A strong link profile in one market does not automatically transfer to another.

Why do local links matter for international rankings?

Google does document this, and more clearly than most SEO writing on the subject suggests. Setting out how it determines a page’s target locale, Google lists ccTLDs, hreflang statements, server location, and then a fourth group: “other signals to identify the intended audience of your site can include local addresses and phone numbers on the pages, the use of local language and currency, links from other local sites, or signals from your Business Profile (where available)”.¹

Be precise about what that establishes, though, because the distinction matters for how much effort to spend. Google frames these as signals for working out who a page is for, not as a ranking boost in that market. So the documented part is that local links help Google identify your intended audience; the inference is that clearer audience identification converts into better visibility in that market. That inference is reasonable and widely held, but it remains an inference.

This does not mean global links are worthless for international pages. Authority transfers across domains regardless of geography. But in competitive international markets where local competitors have deep local link profiles, a purely global link strategy often leaves country-specific pages underperforming against locally rooted alternatives. A mix of high-authority global links and locally relevant local links is what competitive international sites tend to have.

Keep the ceiling in view as well. Google’s own position on link weight has moved: Andrey Lipattsev called links a top-three ranking factor in 2016, but Gary Illyes told Pubcon Pro in 2023 that people overestimate their importance and that they have not been a top-three factor “for some time”.² Local links are worth earning; they are not the whole of an international strategy.

How do you identify local link opportunities?

For each target market, start by understanding which local sources are authoritative and relevant:

Local press and news sites: national newspapers, trade publications, regional news outlets. In many markets, a link from the national paper of record carries both substantial authority and a strong geographic signal.

Industry associations and trade bodies: most countries have industry associations with membership directories or partner listings. These provide local citations as well as links.

Government and institutional sites: where relevant (public sector contracts, educational resources, regulated industries), links from .gov, .ac.uk, or their country equivalents carry strong authority and clear local signal.

Local business directories: the equivalent of the UK’s Yell or Thomson Local, specific to each country. Quality varies, and the bar is a real one: Google’s link spam policy names “low-quality directory or bookmark site links” outright.³ Focus on directories that are actively maintained, genuinely used in the market, and editorially reviewed.

Local bloggers and content creators: in some markets, specialist bloggers carry meaningful domain authority and a locally engaged audience that is relevant to your topic.

Chambers of commerce and local business networks: most countries have formal business networks that list and link to member organisations.

Outreach in the target language

Link building outreach to editors and publishers in a foreign market requires communication in the target language. An outreach email in English sent to a German editor will receive a significantly lower response rate than one written in German. Options:

• Use a native-speaking team member or freelancer to write and send outreach copy.
• Brief a local SEO or PR agency to conduct outreach on your behalf.
• For other English-language markets (Australia, Canada, Ireland), outreach in English is appropriate but should reference locally relevant context and angles.

Digital PR for international markets

Digital PR (creating content that earns press coverage and links) is one of the most effective international link building strategies because it generates multiple links from a single campaign. The challenge is that what works as a PR story in one country rarely transfers directly to another.

A campaign about UK housing prices will not earn coverage in France. A campaign about German employment culture will not earn links in Australia. International digital PR requires:

• Locally sourced data or research (local surveys, government data, industry reports)
• Stories framed around local issues or current events in the target market
• Pitching to local journalists with a locally relevant angle

Adapting an existing campaign concept for a new market (changing the data source, the statistical focus, or the hook) is more efficient than creating campaigns from scratch, but requires genuine localisation of the story angle. Translation alone is insufficient.

Where international link campaigns go wrong

Two guardrails, because both are easy to walk into when buying help in a market you don’t know.

Paid placements on local publishers. Agencies in unfamiliar markets routinely sell placement on local news domains. Where content is published on a host site mainly to borrow that host’s ranking signals, Google’s site reputation abuse policy applies: it defines the practice as “third-party content is published on a host site mainly because of that host’s already-established ranking signals, which it has earned primarily from its first-party content”.³ Google is clear that third-party content is not itself the problem, “it’s only a violation if the third-party content is published on a host site mainly because of that host site’s already-established ranking signals”.³ Genuine editorial coverage is fine; buying a slot on a newspaper’s domain to rank is not.

Expecting a penalty, getting silence. Google’s model for manipulative links is nullification rather than punishment. Its December 2022 link spam update states that its systems “aim to nullify these unnatural links at scale”, and that “ranking may change as spammy links are neutralized and any credit passed by these unnatural links are lost”.⁴ The practical consequence for an international campaign is that a bought link profile usually produces no visible penalty and no benefit either, which is harder to diagnose than a penalty would be.

What about markets where Google isn’t dominant?

The advice above is derived from Google’s documentation and applies to Google’s systems. In several major markets that is not the engine to optimise for: Baidu in China, Yandex in Russia, Naver in South Korea. Their treatment of links differs, and in some cases the more consequential work is platform presence rather than link acquisition. Research the surfaces a market actually uses before porting a Google-shaped link strategy into it. International keyword research covers how to establish that per market.

How do you measure local link profile strength?

When auditing international link profiles:

• Filter your backlink analysis tool by the linking domain’s country TLD. Most tools (Ahrefs, Semrush) support this. Don’t filter by the linking site’s server location: John Mueller, asked directly whether IPs matter for a backlink profile, answered “Nope”, adding that “the server location can be anywhere, especially if you’re using a hosted CMS or a CDN. Link building by IP address seems futile and a bad use of time.”⁵ (Your own server location is a different question, and Google does list it as a weak locale signal for your site.¹)
• Watch out for the ccTLDs that aren’t country signals at all. Google treats around twenty vanity ccTLDs as generic, including .ai, .co, .io, .me, .tv and .ws, plus .eu and .asia as generic regional domains.¹ A German-market audit that counts .io and .co domains as country-targeted is measuring noise.
• Compare the proportion of locally relevant links (from country-relevant domains) for each of your international pages against the top-ranking competitors for your target keywords in that market.
• Identify the gap: are your German competitors earning links from domains your German pages lack? Those domains are the target list for outreach.

Tracking progress across markets

Maintain a separate link building record for each target market. Tracking all international link building in a single spreadsheet obscures which markets are being actively worked and which are stagnant. Review each market’s link profile quarterly: new links, lost links, and progress against the competitive benchmark.

Frequently asked questions

Does a high-authority global domain help more than a local domain with lower authority?
It depends on the competitiveness of the market and the topical relevance. In very competitive markets where local competitors have deep local link profiles, a combination of high-authority global links and locally relevant local links outperforms a strategy focused on global authority alone. In less competitive markets, even a handful of local links can be a meaningful differentiator.

Should I build links to the subdirectory or the root domain for international pages?
For subdirectory-based international sites, links to either location help the overall domain. Links directly to the international subdirectory pages have the most direct impact on those specific pages. Links to the root domain distribute benefit across the whole site, including international pages.

How long does it take to build a competitive local link profile in a new market?
There is no published figure for this, and any specific number is a practitioner estimate rather than a measured result. As a planning assumption, treat it as a matter of quarters rather than weeks, and expect high-competition markets to take considerably longer. Starting with a few high-quality local links (local press, trade associations) and expanding from there is more effective than volume-focused approaches.
