International SEO strategy: a step-by-step plan for UK businesses

An international SEO strategy is a plan for earning search traffic in countries or languages beyond your home market. For a UK business it comes down to four decisions: which market to enter first, how to structure the URLs, how to localise the content, and how to measure each market on its own. Get the order right and the technical work follows.

Most guides on this topic start with hreflang. We think that is the wrong place to begin. The tags are the easy part. The hard part is choosing a market you can actually serve, then building pages that people there would choose over a local competitor. Below is the plan we use at ProntX.

Key takeaways

• Pick one market first and prove it before adding more. Score candidates on demand, fit and your ability to deliver.
• Google recommends separate URLs for each language or country version. It does not recommend URL parameters or cookie-based switching.
• Hreflang tells Google which version suits which searcher. Every version must list itself and all the others, or the tags can be ignored.
• Do not use “UK” as a region code. Google ignores it. Use en-GB.
• Translation is not localisation. Keyword research, prices, delivery terms and examples need to be rebuilt for each market.
• Measure each market separately in Search Console and GA4, with its own targets.

When does a UK business need an international SEO strategy?

You need one when overseas demand already shows up in your data, or when the business has decided to sell into a new country. Building foreign-language pages on a hunch tends to produce a lot of thin pages and very little revenue.

Signs that it is time to plan properly:

• Search Console shows clicks and impressions from countries you do not market to.
• Enquiries or orders arrive from abroad even though checkout, delivery or pricing were built for the UK only.
• You have a distributor, partner or sales hire in another country who needs a site to point people to.

If none of these apply, your budget is probably better spent strengthening UK rankings first. A site that struggles at home rarely does better in a market where it has no reputation at all.

How do you choose which country to target first?

Choose the market where real demand, commercial fit and your ability to serve customers overlap most. Score each candidate country against the same criteria, then start with the highest total.

This is the scoring framework we use. Rate each factor from 1 to 5 for every candidate market.

English-speaking markets such as Ireland, Australia or the US often score well on language effort, but do not assume they are easy. Spelling, product names, pricing conventions and even the words people search with differ. A UK store selling “trainers” will need different keyword targets in the US.

Before you build anything, take legal and tax advice on selling into the market. Rules on VAT, consumer rights and data handling differ by country and can change what you are able to say on the page.

Which URL structure should you use for international pages?

For most UK businesses entering one or two new markets, subfolders on the existing domain (for example example.co.uk/ie/ or example.com/de/) are the simplest starting point. Country domains give the clearest signal but cost more to run. Google does not recommend URL parameters.

Google’s documentation on managing multi-regional and multilingual sites sets out the trade-offs. In short:

1. Country-code domains (example.de): a clear country signal, but each one is effectively a separate site to build, host and earn links for, and some countries have registration requirements.
2. Subdomains (de.example.com): easy to set up and can sit on separate servers, but visitors cannot always tell whether “de” means a language or a country.
3. Subfolders (example.com/de/): easy to set up and maintain on one host, and new sections sit on the domain you have already built up.
4. URL parameters (example.com?loc=de): marked as not recommended by Google.

One UK-specific point: a .co.uk domain is a country-code domain, so it signals the UK. If you plan several markets, a .com with country or language folders is usually cleaner than hanging foreign sections off .co.uk. Google treats some country codes, such as .io, .co and .ai, as generic domains, so they do not tie you to one country.

Two further rules from the same guidance are easy to miss. Google ignores location meta tags such as geo.position, and it treats IP-based content switching as unreliable. Do not redirect visitors automatically by IP or browser language. Show a clear country or language switcher instead, so people and crawlers can reach every version.

How does hreflang fit into the strategy?

Hreflang is the annotation that tells Google which language or regional version of a page to show to which searcher. It does not make pages rank on its own. It helps the right version appear once the pages have earned their place.

Google’s page on localised versions of a page (updated September 2026) lists the rules that matter most:

• You can add hreflang in the HTML head, in HTTP headers, or in your XML sitemap. Google treats the three methods as equivalent, so choose one and keep it consistent.
• Each version must reference itself and every other version. If two pages do not point to each other, the tags can be ignored.
• Use full URLs, including https://.
• Codes are ISO language codes with an optional ISO country code, such as en-GB, en-IE or de-AT. A country code on its own is invalid.
• “UK” is not a valid region code and is ignored. British English is en-GB.
• Use x-default for a fallback page, such as a country selector, for searchers who match none of your versions.

Google also notes that translated pages are only treated as duplicates when the main content stays untranslated. Two English versions for the UK and Ireland that are almost identical can still be grouped, which is why localising the content matters as much as the tags. If you are unsure whether your current setup is sound, a technical SEO review will usually catch missing return links and wrong codes quickly.

A practical note: the old International Targeting report in Search Console has been deprecated. Google says country targeting through Search Console “is no longer supported” and that it will continue to use hreflang. Older guides that tell you to set a target country in Search Console are out of date.

How do you localise content for another country?

Localising means rebuilding each page for how people in that market search and buy, not running the UK copy through a translator. Start from fresh keyword research in the local language, then adapt prices, delivery terms, examples and proof to suit.

A localisation checklist for each priority page:

• Keyword research done in the target language and country, using terms locals actually type.
• Copy written or reviewed by a fluent speaker who knows the sector.
• Prices in local currency, with tax treatment shown the way local buyers expect.
• Delivery times, returns and support hours stated for that country.
• Local contact details where you genuinely have them. Do not invent addresses.
• Examples, units, date formats and spelling adapted.
• Title tags, meta descriptions and image alt text localised, not left in English.
• One language per page, including navigation. Google says it works out page language from visible content, so mixed-language pages send a muddled signal.

Start with the pages that make money: the home page, main category or service pages and your best-selling products. Translating hundreds of old blog posts in week one adds cost without much return. Our article on building an SEO content plan covers how to decide which pages earn a place.

How do you build authority in a new market?

Earn mentions and links from sites people in that country already trust. Links from UK sites help your domain overall, but local signals such as country press, trade bodies, suppliers and directories tell search engines the business is relevant there.

Google lists local links, local language and currency, and local addresses among the signals it uses to judge which locale a site is aimed at. Realistic sources include:

• Distributors, stockists and partners in the country linking to your local section.
• Local trade associations and industry directories you qualify for.
• Coverage in local trade press, pitched in the local language.
• Events, sponsorships or webinars run for that audience.

How should you measure international SEO?

Measure each market as its own project with its own baseline and targets.

Set up the following before launch:

1. Search Console: filter the Performance report by country and by the URL folder (for example /de/) to see impressions, clicks and queries per market.
2. GA4: build a comparison or segment for each country and each local section, and track conversions there rather than sitewide only.
3. Rank tracking: track a short list of local-language keywords in each target country, not the UK version.
4. Hreflang checks: crawl the site monthly for missing return links, wrong codes and pages that redirect or return errors.
5. Business results: enquiries, orders and revenue by country from your CRM or shop platform.

Agree in advance what “working” means for the pilot market, for example a level of qualified enquiries or orders, and the date you will review it.

What does international SEO mean for AI search?

AI search tools such as Google’s AI Overviews answer in the searcher’s language and often draw on pages that state facts clearly. Pages that answer local questions directly, in the local language, with accurate prices and delivery terms for that country, give these systems something precise to quote.

The basics are the same as for ordinary search: separate URLs per version, clear language signals and self-contained answers. We cover the wider approach in our guide to optimising for AI search.

What does a phased international SEO plan look like?

A phased plan launches one market, measures it, then repeats. The steps below are the order we follow. Timings depend on the size of the site and how quickly translated content can be produced and reviewed.

1. Audit: check current overseas traffic, technical health and whether the CMS supports language or country versions.
2. Score markets: use the framework above and pick one.
3. Research: run local keyword and competitor research for that market.
4. Decide structure: subfolder, subdomain or country domain, and how hreflang will be generated.
5. Build priority pages: localised home, service or category pages and top products.
6. Launch and validate: check hreflang, sitemaps, switchers and analytics before announcing.
7. Build local authority: partner links, local press and directories.
8. Review: compare results against the targets you set, then decide on the next market.

This is the same sequence we use on our international SEO projects, and it applies whether you run a shop or a service business. For online retailers, our ecommerce SEO strategy guide covers the category and product page work that each market will need.

Is your business ready? A quick decision check

Answer yes or no to each question. Four or more yes answers suggest you are ready to plan a pilot market.

• Do you already see traffic or enquiries from the target country?
• Can you deliver, invoice and support customers there today?
• Do you have a fluent speaker to write or review content?
• Does your CMS support separate language or country versions with hreflang?
• Is your UK site technically healthy and ranking for its main terms?
• Have you agreed a budget and a review date for the pilot?
