International SEO Best Practices: How to Plan a Strategy Market by Market

An international SEO strategy is the plan that decides which countries and languages your website will compete in, in what order, with what budget and with which team. It sits above the day-to-day localization work. The strategy answers business questions first. It names the market that can pay back the investment and the number of pages each market needs. It also names who writes those pages and how you will know a market is working.

Flying Cat's founder, Maeva Cifuentes, has run international programs for B2B SaaS companies for more than 15 years, starting in translation and localization and then building her first agency in Spain. The best practices below come from that work across English, French, German, Italian and Spanish. Two programs show up throughout this guide. ActiveCampaign gained 83,000+ more non-branded clicks and 4.1M+ more impressions across its French, Italian, German and Spanish sites in eight months. An ecommerce marketing platform tripled its top-3 rankings in France on a budget of about two articles per market each month. The two programs had very different budgets. Both worked because the strategy fit the budget.

This page covers the strategy layer. For the hands-on localization process, including page audits, native keyword research, glossaries, reviewers, internal links and hreflang setup, read our multilingual SEO guide.

International SEO best practices at a glance

Pick markets with demand data

Market selection is the first best practice because every later decision depends on it. A company that enters four markets at once with a small budget usually spreads too thin to win any of them. A company that picks one market with proven demand can concentrate its budget and show results the board will fund further.

We score candidate markets with five data sources.

1. Revenue signals you already have. Pull signups, demo requests, closed deals and support tickets by country from your CRM and product analytics. Existing customers in a market prove that the product fits there.
2. Search Console country data. Filter performance by country to see where impressions and clicks already arrive without any local content. Branded searches from a country are a strong sign of latent demand.
3. Local keyword demand. A native linguist builds a keyword list for the category in the local language. The total volume of bottom- and mid-funnel terms tells you how large the search opportunity is. Translated English keywords give a false picture here, which is why our international keyword research guide starts from local terms.
4. Competitor traffic by country. Tools like Ahrefs and Semrush show where your competitors earn organic traffic. A competitor with strong traffic in Germany and weak traffic in Italy points to one market with proven demand and one with less competition.
5. AI answers in the local language. Run a handful of buying prompts in ChatGPT, Perplexity, Gemini and Google AI Mode in the target language. Note which vendors get recommended and which sources get cited. Local vendors with strong AI presence signal a harder market.

We combine these into a simple scoring table. Each market gets a score from 1 to 5 on each factor, weighted by the priorities of the business.

The numbers above are an illustration of the format. The weights change by client. A product-led company may weight signups heavily, while a sales-led company weights its sales team's language coverage.

Product fit deserves its own check. Some features, integrations or compliance claims do not apply in every country. A payroll feature built around US tax rules, for example, has no audience in Spain. Remove those topics from the market plan before anyone writes a brief.

Build a business case for each market

Each market needs its own business case, because each one has its own costs, timeline and expected return. A single global SEO budget hides the markets that are not paying back.

The business case we build for each market has five inputs.

• Addressable demand. The monthly search volume of the keywords the market plan targets, split into bottom-, mid- and top-funnel terms.
• Expected visibility. A realistic share of that demand by month 6 and month 12, based on the competition on the local results pages.
• Conversion rates. Your current visitor-to-signup or visitor-to-demo rate, adjusted for the market if your local sales coverage is thinner.
• Deal value. Average contract value in the local currency, since pricing often differs by region.
• Cost. The number of pages per month, the cost per page for native writing and review, technical work and any placements.

The page count is the largest lever. ActiveCampaign's program localized the best English pages and added about twenty new bottom- and mid-funnel pages per language each month. That pace suited a company competing across four large markets at once. The ecommerce marketing platform worked with about two new articles per market each month. It focused that budget on the topic clusters closest to the product and finished each cluster before starting the next one. In year one, its French organic impressions grew 506%, its ranked keywords in France grew 6.8x. Its organic conversions in France grew 60%.

Both programs worked because the plan matched the budget. A small budget can win a market when it concentrates on a few clusters. It fails when it spreads two articles a month across ten unrelated topics. Our guide to forecasting SEO growth covers the forecasting model in detail. Our article on the business case for SEO shows how to present it to leadership.

Launch markets in sequence

Teams often skip sequencing on the programs we audit. Leadership approves an expansion into Europe. The team then launches French, German, Italian and Spanish sites in the same quarter. Each market then gets a quarter of the budget and a quarter of the attention.

The ecommerce marketing platform followed a different path. We proved the model in France for nine months first. Translated pages there had sat in the mid-20s on Google, behind local competitors with years of local-language content and far larger publishing teams. Native writers rebuilt each article around local search habits, retail calendars, regulations and customer examples. Once France moved to page one, we launched the German blog from zero. German blog traffic grew 108% in the first three months after launch. Italy and Spain followed.

The first market produces three assets that make every later market faster.

• A tested workflow, including brief templates, glossary format and review steps.
• Evidence of which content types convert in a non-English market for your product.
• A results story that secures budget for the next market.

Sequencing also applies inside a market. We start with bottom-funnel pages such as product, comparison and use-case pages, then move to mid-funnel guides. Top-funnel content comes last, if at all, since AI answers now cover many general questions directly. Each cluster gets finished before the next one starts.

Decide site structure early

Site structure is a strategy decision because it is expensive to change later. The three common options are subfolders (example.com/fr/), subdomains (fr.example.com) and country-code domains (example.fr). All three can rank. The choice depends on the authority of your main domain, your CMS, whether local teams or legal entities need control of their own site, and whether your markets differ by language only or also by country.

A company with a strong .com and one central marketing team usually does best with subfolders. A company with established local domains and separate country teams may do better keeping them. Migrating a ranking ccTLD into a subfolder carries risk, so it needs a clear reason. Our multilingual SEO guide compares the options in a table, and our hreflang guide covers implementation.

Two points belong in the strategy itself. First, Google's Search Console no longer supports country targeting through its old International Targeting report. Hreflang tags, local content and local signals carry that job now. Second, plan for technical risk at the strategy level, because rendering problems can erase a whole market. During a content audit, we found that an AI tax research platform's Canada pages drew almost no traffic. A JavaScript-rendered crawl showed 99.9% of the Canadian answer pages redirecting in the browser to their US versions, even though they returned a 200 status and carried hreflang tags. For a veterinary software client, a re-platform to a JavaScript app left all 22 of its French pages serving Googlebot an empty shell with an English title. Build a technical check of every language version into each migration plan and each quarterly review. Our technical SEO service runs these checks for international sites.

Choose a team and workflow model

The team model decides quality in every market. Three models work. Each one fits a different kind of company.

Whichever model you pick, keep strategy central and writing local. For the ecommerce marketing platform, outlines are written in English so the client's core team can review structure and positioning in one language. Native writers then write the final drafts directly in French, German, Italian or Spanish. Each draft gets a sign-off from a reviewer in each market, across the UK, France, Germany, Spain and Italy. Once an outline is approved, its structure is locked, so the market drafts stay aligned on the topics and internal links the strategy depends on.

Native writers bring market knowledge that a translator does not. For our veterinary software client, burnout messaging that works in North America does not land the same way with French vets. "SOAP notes" is the standard term in North America, while UK and European vets more often say "medical records". The strategy has to give writers room to change the angle, examples and terms for each market.

The workflow also decides when to translate, localize or write new pages. ActiveCampaign's program used both approaches. We localized the best English pages with local examples, images and tone. We also wrote new pages for keywords the English site did not cover. Our article on localization versus translation for SaaS explains where each one fits, and the multilingual SEO guide covers the page-by-page audit.

At Flying Cat, our founder leads the strategy on every account. Native freelance specialists who know the client's vertical handle research and writing in each language. That model keeps one strategy across markets while every page reads as if a local expert wrote it.

Plan authority for each market

Each market builds authority in its own ecosystem. A French page benefits from French publications, French industry sites and French vendor roundups. Links from US sites help the domain overall, but they send a weaker signal about which market a page serves.

Your plan should list the local sources that buyers and AI assistants trust in each market, such as trade media, review sites, associations and partner directories. Link building norms also vary by country, so your outreach approach should be planned with someone who knows the local media. Our link building strategies guide covers the methods, and our link building service runs placements in each language.

Some companies cannot build links at all. At the ecommerce marketing platform, company policy ruled out link building. Legal also blocked comparison articles that named competitors. The client still tripled its top-3 rankings in France. Native content focused on a few topic clusters did the work, because each page answered the local search better than the competing pages did. A strategy can still win a market under tight rules when it puts the budget into content depth.

Track AI visibility in each market

AI search changes international SEO strategy in three ways.

First, AI answers now reach every market you might enter. Google expanded AI Mode to more than 40 new countries and territories and more than 35 new languages in October 2025, bringing it to over 200 countries and territories. Buyers in Paris, Munich, Milan and Madrid ask ChatGPT, Perplexity, Gemini and Google AI Mode the same vendor questions as buyers in the US.

Second, AI assistants pull English sources into non-English answers. Peec AI analyzed more than 10 million ChatGPT prompts and found that 43% of the background searches for non-English prompts ran in English. English vendor lists can shape the answer a German buyer reads. A strong English site helps you in every market. A weak local presence lets English-language competitors fill the answer.

Third, the cited sources change by language. Profound studied 3.25 billion AI citations across 14 countries and found that query language shapes which sources AI assistants cite more than geography does. In Spanish Google AI Overviews, for example, TikTok made up about 16% of social citations, roughly five times its share in English. The third-party pages that win AI visibility in France differ from the ones that win it in the US.

These findings shape the AI visibility plan for each market.

1. Build a separate prompt set per market, written by native speakers in the way local buyers ask. Our AEO guide to prompt research explains the method.
2. Run each market's prompts from that country and track presence, citations and share of voice against local and global competitors.
3. List the local third-party pages that AI assistants cite in each market. Those pages become targets for placements and content updates.
4. Report AI visibility as a percentage across many prompts. Position in a single AI answer changes too often to track reliably.

The results follow the search results when the content is strong. The ecommerce marketing platform ranks first in AI answer presence among tracked competitors in all five of its markets. Over three months to May 2026, its AI referral users grew 522% in France, 281% in Spain and 150% in the UK. In August 2026, its German ChatGPT sessions grew more than 35-fold and began producing signups. Our veterinary software client ranks first in French AI share of voice at about twice its nearest competitor. Our GEO and AEO service runs this tracking for each language we cover.

Measure each market on its own baseline

Each market needs its own baseline, its own targets and its own report. Blended global numbers let a growing market hide a struggling one.

Reporting cadence shapes how teams read results. For the ecommerce marketing platform, we moved reporting in September 2025 from raw impressions to clicks, conversions and page-one visibility. Monthly reports compare month over month. Quarterly reviews compare year over year. In January 2026, clicks across its five EMEA markets grew 47.4% year over year. Ranked keywords grew 187.3% in the same comparison. By August 2026, "email marketing" in France had climbed from rank 48 to rank 1. The same month brought rank 1 positions in the UK, Spain, Germany and Italy.

Set expectations by market age. A new market spends its first three months building a baseline and publishing the first cluster. Movement in impressions and long-tail rankings usually comes next, then clicks, then conversions. Review each market quarterly against its business case and decide whether to scale, hold or pause it. Our SEO metrics guide covers how we define each metric.

Common reasons international programs stall

The programs we audit tend to stall for a small set of reasons. Each one traces back to a strategy decision.

• Translated pages instead of local ones. Translated keywords and examples miss how local buyers search. The ecommerce marketing platform's translated pages sat in the mid-20s until native writers rebuilt them.
• Too many markets at once. The budget spreads thin. No market reaches page one.
• No owner per market. Pages go live without review. Nobody notices when a market declines.
• Technical breakage after a migration. Language versions disappear from Google without anyone checking how Googlebot sees them.
• Global reporting only. A blended number hides the market that needs attention.

Our list of international SEO mistakes covers these in more depth.

Frequently asked questions about international SEO strategy

What is the difference between international SEO and multilingual SEO?

International SEO is the full program of ranking a website in more than one country or language. Multilingual SEO is the part focused on language versions, such as French and German pages. Multi-regional SEO is the part focused on countries that share a language, such as US and UK English pages. Our international SEO blog collects articles on each part.

How long does international SEO take to show results?

ActiveCampaign's program produced 83,000+ more non-branded clicks in eight months. The ecommerce marketing platform tripled its top-3 rankings in France within six months. Expect the first three months to go into research, setup and the first cluster, with measurable growth in impressions and rankings after that.

Should I translate my existing site or create new content for each market?

Use both. Localize existing pages where search intent matches in the target market. Write new pages for local demand your English site does not cover. Topics tied to local rules, local competitors or local buying habits almost always need new pages.

Where to start with your international SEO strategy

Start with one market where you already see demand in your CRM and Search Console data. Build a business case for it, choose the team model and publish one bottom-funnel cluster with native writers. Track search and AI visibility against a baseline from day one. Expand to the next market once the first one shows results.
