How to buy international SEO

1. Name the markets and the priority order. List target countries and languages, and rank them. Global programmes fail when every market is equal priority, because budget and content capacity are finite and the strongest market subsidises the rest.
2. Settle the site structure first. Country domains, subdirectories and subdomains each carry different costs in authority, hosting and administration. This decision constrains everything after it, so it belongs in the first month, not in a later phase.
3. Insist on localisation, not translation. Ask who researches keywords natively in each market and who reviews the copy. Machine translated pages with a native reviewer can be acceptable; machine translation with no review reliably produces pages nobody searches for.
4. Plan in market authority work. Links and citations from sources inside each target country carry weight that home market coverage does not. Ask what the agency has actually earned in your target markets, with named referring domains, before you accept a plan that assumes it.

The technical layer that decides visibility

Google publishes documentation on localised versions of a page and on managing multi regional sites, and a credible international agency will reference it rather than improvise. The core requirements are consistent: each language or country version needs its own crawlable URL, the annotations that connect the versions must be bidirectional and self referential, and content should not be swapped based on a visitor's detected location in a way that hides a version from crawlers or from users who want it.

Ask a candidate to audit these before quoting. A short technical review will usually reveal whether the existing structure is salvageable or whether the first quarter of the engagement is a migration. Agencies that quote content volume without looking at structure are quoting the visible half of the job.

What a real international capability looks like

Coverage claims are cheap. Ask which markets the agency has native speakers for, whether those people are employees, contractors or a partner agency, and how many hours a month your programme buys from each. Ask for a named client in a comparable market and, if possible, a redacted report from it. An agency serving three markets well is a better buy than one claiming forty through a network it has never audited.

Ask also about the operational load you will carry. International programmes generate translation queues, legal reviews and country specific approvals, and the agency will need a counterpart in each market or the work will stall on your side. A bidder that raises this unprompted has run one before.

Pricing and sequencing

Global programmes price by market count more than by hours, and the first market is always the most expensive because it carries the structural work every later market reuses. Ask for a per market incremental price alongside the total, and for an explicit split between one off structural work and ongoing content and authority work.

Sequencing matters as much as price. Launching six markets simultaneously with a thin content plan usually produces six weak presences. Proving the model in one or two markets, then reusing the structure, gives the programme evidence to argue for its own budget, which is the practical reason to insist on a priority order at the start.

Questions people actually ask

Country domains, subfolders or subdomains?

All three can work and Google's documentation on multi regional sites sets out the trade offs. Country domains signal geography clearly but split authority and multiply administration. Subfolders consolidate authority and are usually simplest. The right answer depends on your resources, so make an agency argue its recommendation rather than assert it.

Is machine translation acceptable?

With native review and market specific keyword research, often yes. Without review, it produces pages that read poorly and target phrases nobody uses locally. Ask specifically who reviews, in which markets, and how much time is budgeted for it.

Should we auto redirect visitors by country?

Be careful. Automatic redirects based on detected location can prevent users and crawlers from reaching versions they want. A visible suggestion banner that lets the visitor choose is the safer pattern, and it keeps every version reachable at its own URL.

How many markets should we start with?

Fewer than you want to. Start with the one or two markets that carry the clearest demand and the internal capacity to support content approval, prove the structure, then expand. The structural work is reused, so later markets cost less than the first.
