An international SEO agency should prove it can handle hreflang, URL structures, and geotargeting signals before you hire it. Look for documented hreflang skill, market-specific content planning, and honest timelines. These 7 checks separate real international SEO agencies from ones that only translate your homepage.

If you are comparing every international SEO agency on your shortlist, this guide gives you the questions that matter. It follows Google’s own documentation on multi-regional sites, so you can spot answers that no longer hold true. For a full technical workup, start with an SEO audit that covers your target markets.

What does an international SEO agency actually do?

An international SEO agency helps the right version of your site reach searchers in each country and language you serve. Google draws a line between two jobs here. A multilingual site offers content in more than one language, like a Canadian business with English and French versions. A multi-regional site explicitly targets users in different countries, like a manufacturer shipping to both Canada and the US. Your agency should know which one you are building, because the setup differs.

The core work is technical before it is creative. The agency maps each language and region to its own URL, connects those versions with hreflang annotations, and builds the country signals Google actually reads. An international SEO agency that jumps straight to translation without a URL and hreflang plan is skipping the part that makes the whole project work.

Which URL structure should an international SEO agency recommend?

Every international SEO agency you interview should explain the four URL structures Google documents, and why one fits your situation. Google treats none of them as a guaranteed ranking boost. The choice is about cost, hosting, and maintenance, not about tricking the algorithm.

URL structure	Example	Strengths	Weaknesses
Country-specific domain (ccTLD)	example.de	Clearest country signal to users and Google; server location irrelevant; easy separation of sites	Expensive; sometimes limited availability; more infrastructure; strict registration rules; targets only one country
Subdomain with gTLD	de.example.com	Easy to set up; allows different server locations; easy separation of sites	Users may not read it as a country signal; harder to read whether it means language or country
Subdirectory with gTLD	example.com/de/	Easy to set up; low maintenance; runs on the same host	Weaker country signal; single server location; separation of sites is harder
URL parameters	site.com?loc=de	None documented	Not recommended by Google; URL-based segmentation is difficult

Verdict: most small and mid-size businesses land on subdirectories, because they are cheap to run and inherit the domain’s existing authority. Pick a ccTLD only when a market justifies its own legal and hosting setup. If an international SEO agency recommends URL parameters, end the call. Google’s own documentation calls that option not recommended.

How do you test an international SEO agency’s hreflang skill?

Ask the agency to explain how it implements hreflang, then check the answer against Google’s rules. Google supports three methods: link tags in the HTML head, HTTP headers, and XML sitemaps. All three are equivalent in Google’s eyes, and running all three at once has no Search benefit, so a careful agency picks the one its setup can generate reliably.

Then listen for the three rules that break everything else. First, every language version must list itself as well as every other version, with fully-qualified URLs. Second, the links must be bidirectional: if page A names page B as its German alternate and page B does not point back, Google ignores the whole annotation. Third, language codes must come from the ISO 639-1 standard with an optional ISO 3166-1 Alpha 2 region code, like en-US, and an x-default value should catch visitors whose language matches no variant. An international SEO agency that cannot recite these rules will not fix your broken ones.

What geotargeting signals does Google actually use?

Google lists four signal groups it uses to work out a page’s target audience: country-code domains, hreflang statements, server location, and other signals such as local addresses and phone numbers, local language and currency, links from local sites, and Business Profile data. Server location is explicitly not definitive, because CDNs and overseas hosting are so common. And Google ignores locational meta tags like geo.position or distribution, along with geotargeting HTML attributes. Any agency still quoting those tags as levers is years behind.

There is also a setting that no longer exists. Google’s Search Console International Targeting report, launched in 2014, was removed on September 22, 2022. Its Country section let site owners set a site-wide country target; its Language section listed hreflang errors. Google said country targeting there had little value and is no longer supported, while hreflang remains fully supported. If a pitch deck still shows screenshots of that report, the agency has not kept up.

What should an international SEO agency never promise?

It should never promise rankings in a specific country by a specific date. Google’s documentation says plainly that geotargeting is not an exact science. You can influence which version shows where, but you cannot command it. Promises of guaranteed country rankings are fiction, not strategy.

It should also never propose redirecting visitors automatically based on guessed language or location. Googlebot usually crawls from the USA and sends requests without an Accept-Language header, so auto-redirects can stop Google from finding and crawling your variations at all. Google recommends letting users pick their region or language with visible links instead. An international SEO agency pushing hard auto-redirects is risking your crawl coverage for a small UX gain.

What are the 7 smart checks for choosing an international SEO agency?

Run every candidate through this list. A strong agency answers each one without hesitation.

1. Multilingual versus multi-regional: can the agency name which problem you have, using Google’s distinction, and explain why the answer changes the setup?
2. URL structure trade-offs: does it compare ccTLDs, subdomains, subdirectories, and parameters honestly, including cost and maintenance, instead of pushing one answer for everyone?
3. Hreflang fluency: can it explain self-referencing tags, bidirectional return links, valid ISO codes, and x-default fallbacks without looking them up?
4. Dead signals: does it know Google ignores geo meta tags, and that the Search Console country targeting setting was removed in 2022?
5. No auto-redirects: does it recommend visible language and region selectors instead of redirects that can block crawling?
6. Content depth: does it warn you that translating only the template while the main content stays untranslated counts as duplication and hurts users?
7. Honest limits: does it say geotargeting is inexact and timelines depend on crawling and competition, instead of guaranteeing country rankings?

Picture a US-based store expanding to the UK and Germany with otherwise identical English pages for the US and UK. A real international SEO agency would flag the duplicate-content risk, set up en-US, en-GB, and de variants with bidirectional hreflang, recommend subdirectories to start, and use x-default for everyone else. An agency that only translates the homepage would leave you with three competing URLs and no way for Google to tell them apart.

When is an international SEO agency not worth hiring?

Sometimes the honest answer is not yet. If your expansion is one small market, or English-speaking countries where your existing content already reads naturally, the technical work may be a few dozen hreflang tags and a subdirectory, not a full engagement. Machine-translated product descriptions with no native review also fail the deeper test: Google treats pages as duplicates when the main content stays untranslated, so thin translations can create more problems than they solve. Spend the budget on quality translation first, then bring in the agency for the technical layer.

A consultant review can confirm whether your situation needs a full international program or a short technical project. Either way, you pay for what the situation demands, not for a retainer built around a guess.

How do you measure international SEO?

Since the International Targeting report is gone, measurement runs through the reports that remain. Filter the Search Console Performance report by country to see which markets are actually gaining impressions and clicks. Use URL Inspection to confirm which canonical Google picked for each variant and to read the rendered HTML. For hreflang errors, run a crawler, because Search Console no longer lists them.

Set expectations with your agency up front: Google needs to recrawl every variant before localized results change, and crawl capacity varies by site. Movement usually appears market by market over weeks to months, not everywhere at once. Track one market at a time and compare against its own baseline, not against your home market.

What should you do next?

1. List every country and language you actually serve, not ones you hope to serve someday.
2. Check your current site against the 7 smart checks above and note where you fail.
3. Run a crawler on your hreflang tags to find missing return links and invalid codes.
4. Pick one URL structure per market and document it before any developer touches code.
5. Get a free SEO audit that covers your international setup, so the fixes start from evidence.

Do international SEO agencies charge more than regular SEO agencies?

No standard price exists; scope scales with markets and languages. Quotes vary with URL work, hreflang fixes, translation quality, and monitoring. Rank OG publishes Starter $150, Growth $280, Scale or AI-First $799, USD, scoped after a free audit. The site names no billing period, so ask before signing.

Should I use a ccTLD or a subdirectory for a new market?

A ccTLD sends the clearest country signal but is expensive, sometimes restricted, and can only target one country. A subdirectory is cheap, easy to maintain, and inherits your domain’s authority. Most businesses start with subdirectories and move to ccTLDs only when a market justifies separate hosting and legal structure.

Is hreflang still needed after Google removed country targeting?

Yes. Google confirmed it continues to support hreflang even after removing the International Targeting report in September 2022. Hreflang is now the main structured way to tell Google which URL serves which language or region, so its importance actually grew once the manual country setting disappeared.

How long does international SEO take to show results?

Expect weeks to months, not days. Google must recrawl each localized variant before results change, and each market moves on its own timeline. Speed depends on your site’s crawl capacity, how many variants exist, and competition in each country. Any agency promising results in every market at once is overselling.

Can one international SEO agency handle translation and SEO together?

It can coordinate both, but the two are different skills. Translation quality decides whether content ranks and converts; hreflang and URL structure decide whether the right version reaches the right searcher. Ask if a native speaker reviews each market. Without that review, your technical setup serves poor content perfectly.
