International SEO outsourcing for agencies

Add the international SEO expertise your project needs to your team.

Got a client expanding into new markets, a complex multi-country migration, or a project combining SEO, GEO and multilingual content? SEOSEMPERE works alongside your agency, taking on agreed strategy and delivery without you needing to hire.

Your agency stays in charge of the client relationship and commercial decisions. We provide specialist expertise, delivery capacity and close coordination with your team.

Tell us about your project What we can take on

Experience across projects in more than 30 countries and 20 languages

Extra capacity, when you need it

You don’t need to outsource everything. Just the expertise or capacity you’re missing.

Your team may already be doing excellent work. But some projects call for international experience, more delivery capacity, or both.

We fit around what you’ve already decided and take responsibility for the work that makes sense to delegate, without forcing you to rethink the whole project.

Your client is entering new markets

You know SEO in your home market, but need local search research, competitor analysis and content strategy for countries such as France, Germany or the UK.

An international website migration is underway

You need to make informed decisions on site architecture, hreflang, redirects and indexation, and work with developers to implement them.

Clients are asking about Google and AI search

They want to know about ChatGPT, Gemini, Perplexity and Google’s AI search features. You need an evidence-led approach to visibility.

Your SEO team needs additional capacity

You know what needs doing, but need support with market research, page optimisation and technical delivery.

What we can take on

Strategy, delivery and organic visibility across international markets

We combine international SEO, GEO and AEO with strong technical and content foundations. We build on the work your team has already done and agree who leads, delivers and signs off each task.

International SEO strategy and visibility

We research markets, search behaviour and competitors to identify where to focus your efforts.

View scope

We can handle country- and language-specific keyword research, search intent, local competitor analysis, market prioritisation and commercial page and content planning. The outcome is an actionable plan, not just a spreadsheet of keywords.

Technical SEO and international migrations

We plan and review international site architecture and the technical changes your website needs.

View scope

We work on domain and subfolder structures, hreflang, canonicals, crawling, indexation, sitemaps, redirects and migrations. We prepare developer requirements, carry out changes within the agreed scope and validate the implementations we are responsible for.

GEO, AEO and AI search visibility

We work to improve how a brand is discovered, understood and represented in Google and AI-powered search.

View scope

We review relevant prompts, responses, brand mentions, citations, sources, the clarity of company and product information, content and authority signals. Where appropriate, we can monitor visibility in ChatGPT, Gemini, Perplexity and Google’s AI search experiences. We cannot guarantee specific mentions, citations or recommendations.

Multilingual SEO and content localisation

We adapt pages to the searches, terminology and buying needs of each local market.

View scope

We research local terminology, search intent and solution comparisons. We plan content structures, prepare briefs, optimise product and service pages, and coordinate with writers and translators. Localisation is more than translation.

B2B and industrial SEO

We have experience with manufacturers, engineering firms and businesses selling technical products and solutions.

View scope

We work on product, application and industry pages designed around professional purchasing needs. The aim is to help the right buyers find the company, understand its offering and consider it as a potential supplier.

SEO delivery, measurement and reporting

We take ownership of agreed tasks and keep your team clear on what has been delivered and what comes next.

View scope

Depending on scope: on-page optimisation, internal linking, metadata and structured data reviews, technical checks, market-level reporting and tracking relevant queries and pages. For AI search, we record repeatable observations where sufficient data exists and distinguish delivery, leading indicators and commercial outcomes.

Flexible ways to work together

Two ways to work with your agency

01 / One-off project

Specialist support for a defined challenge

An international migration, site architecture, a new target market, a GEO review or a defined part of delivery. We agree scope, ownership, deliverables and timelines.

02 / Ongoing partnership

Ongoing international SEO outsourcing

We join your planning and delivery over several months, working with your agency’s SEO leads. Time commitment and responsibilities are agreed for each project.

There’s no need to outsource work your in-house team already handles well.

How we work

We work alongside your team, not against your processes

We understand the project

Goals, markets, technology, deadlines and the work you’ve already completed.

We agree the scope

Deliverables, responsibilities, sign-off points and commercial terms.

We work with your team

We coordinate with SEO, development and content teams, and join meetings when needed.

We deliver and document

We share progress, issues and decisions. Any change in scope is agreed in advance.

From brief to delivery

What happens when we join your project?

An international project already in progress

Your agency is building a manufacturer’s website for the UK, France and Germany. Decisions on architecture, localisation and AI search visibility are still outstanding.

See how we’d approach the project

We would start by reviewing what has already been decided and what remains open. Next, we would check the site architecture and language relationships, research commercial search demand in each market and review a defined sample of Google and AI search responses.

Prioritise decisions affecting development.
Define architecture, hreflang and market-specific content requirements.
Create clear tasks for the SEO, development and content teams.
Validate changes within our agreed scope.

Illustrative example only, not a published case study.

More capacity for your agency. Without losing control of the project.

We work with your team to improve visibility in your client’s priority markets, with clear responsibilities and deliverables.

Agency-to-agency collaboration

The client relationship stays with your agency

Outsourcing specialist work shouldn’t mean losing visibility or control over the account.

Your agency owns the commercial relationship

We agree our role in client meetings and how communication with the end client will work.

Clear ownership

We establish who leads, implements and signs off each part of the work.

Documented work and confidentiality

We record decisions and deliverables. We can formalise confidentiality and client account protection arrangements.

SEOSEMPERE brings international experience in multi-country SEO and technical B2B projects.

Common questions

Frequently asked questions

What is the difference between SEO outsourcing and white-label SEO?

With SEO outsourcing, we can work openly alongside your team and join technical client meetings. With white-label SEO, our work is delivered under your agency’s brand and we remain behind the scenes. The distinction is the working model, not necessarily the complexity of the work. If you need to deliver the service entirely under your own brand, explore our white-label international SEO service.

Can you work with our in-house SEO team?

Yes. We can support international SEO projects, take ownership of defined tasks or help with technical decisions while respecting your existing strategy and processes.

Do you also work on GEO and AEO?

Yes, where the project calls for it. We review organic and AI search visibility, the information available about a company, and opportunities to improve content, structure and authority. SEO remains the foundation of our work.

Can you handle strategy as well as delivery?

Yes. Before work begins, we agree what SEOSEMPERE will deliver and what remains with your agency, developers or content team.

Can you attend meetings with the end client?

Yes, when useful and agreed in advance. Your agency retains the client and manages the commercial relationship.

How do you price a project?

Pricing depends on the markets involved, technical complexity, tasks, duration and required capacity. We can quote for a defined project or an ongoing engagement, with clear deliverables and responsibilities.
