Link building is easy to describe and much harder to do well.

You can buy a large number of backlinks and still see very little change in search. A good campaign usually starts with something more basic: finding websites that make sense for the business, creating something worth referencing, and getting the placement through genuine outreach.

That matters even more when a company is targeting several countries. An online store, SaaS company, agency, or publisher may need links from different markets and industries, not simply websites from the country where its SEO partner is based.

If your target markets extend across Eastern Europe, it is also worth exploring the link building agency landscape in neighbouring markets to understand your options.

The companies below take different routes. Motherlink is strongly focused on link acquisition. Ethical SEO leans toward SaaS and digital PR. Others, such as Blu Mint, and Brookelake, place link work inside a broader SEO or digital marketing service.

Quick Comparison

1. Motherlink

Motherlink is one of the most link-focused companies in this list. Its platform gives customers access to more than 20,000 publishing websites, with content available in 25 languages. There is also a managed off-page service where the team handles link strategy, outreach and reporting. Full SEO is available for businesses that want technical work, content and backlinks handled together. The company says its team has more than 50 full-time professionals.

Services Offered

• Self-serve backlink platform
• Managed off-page SEO
• Full SEO and multilingual content

Good Choice For

Companies running ongoing campaigns across several countries or languages.

2. Ethical SEO

Ethical SEO is a Tallinn-based agency that works mainly with SaaS and B2B companies. Its services include organic SEO, ethical link building, PR link building, technical SEO and AEO. The agency puts manual outreach at the centre of its link work and positions the service around relevant placements rather than large volumes of low-quality links. Its current site also focuses heavily on search visibility beyond traditional Google results.

Services Offered

• Manual link building
• Digital PR and PR links
• Technical SEO and AEO

Good Choice For

SaaS and B2B brands that need editorial outreach and organic search growth.

3. Blu Mint

Blu Mint is a full-service digital agency with SEO, content, PPC, web design and social media under the same roof. Its current positioning is aimed at scale-up and enterprise companies, and it works with clients internationally from its Tallinn headquarters and remote teams. Link acquisition is part of its wider SEO approach rather than a stand-alone product. The company says it has completed more than 130 global projects.

Services Offered

• SEO and off-page work
• Content marketing
• PPC and web development

Good Choice For

Growing companies that want link building alongside wider marketing work.

4. LocalRank-SEO

LocalRank-SEO is broader than the title of this article might suggest. Its main services cover website work, SEO, GEO and Google Business Profile optimisation. The agency describes its SEO process as covering audits, technical improvements, keywords, search intent, content and site structure. It says it has worked on both small local projects and larger projects in Estonia and the USA. Dedicated large-scale link outreach is not its main public offer.

Services Offered

• SEO audits and optimisation
• GEO and search visibility work
•  Websites and Google Business Profile support

Good Choice For

Businesses that need broader search work rather than backlink outreach alone.

5. Snoika

Snoika combines backlink building with digital PR and search visibility tracking. Its current services are organised by markets across Europe and the United States, and its backlink campaigns focus on relevant publications, industry directories and PR channels. It also tracks brand mentions and citations across several AI search systems. For international companies, that combination can make sense when the goal is broader visibility rather than a simple increase in referring domains.

Services Offered

• Backlink outreach
• Digital PR and editorial placements
• Search visibility and citation monitoring

Good Choice For

International brands that want link acquisition connected to a wider search strategy.

6. Brookelake

Brookelake Group offers SEO and organic growth as part of a wider digital marketing service. Its site lists link building, technical SEO, paid media and content creation. That makes the company more of a growth partner than a pure link building shop. It can suit businesses already investing in several acquisition channels.

Services Offered

• SEO and link building
• Content creation
• Paid media and traffic generation

Good Choice For

Businesses that want backlink work tied to a larger growth plan.

7. Suvy Marketing OÜ

Suvy Marketing OÜ is a smaller digital agency that combines website development, ecommerce and online marketing. Its listed services include SEO, PPC, social media and email marketing, while its SEO offering includes link earning and development, on-site optimisation and multilingual SEO according to its Clutch profile. It is therefore better viewed as a  general digital partner that can handle link-related work, rather than a specialist outreach agency.

Services Offered

• SEO and link development
• Website and ecommerce development
• PPC, email and social media

Good Choice For

Smaller online businesses that need several digital services from one provider.

8. Wizard on Demand

Wizard on Demand is a technical content marketing agency focused on devtools and enterprise infrastructure companies. Its work covers technical content, information architecture, SEO, GEO and paid media. Link building is part of the way it distributes and promotes technical content rather than being the whole service. That focus is quite different from a general outreach agency, but it can be useful when the subject matter itself is difficult to explain or market.

Services Offered

• Technical content marketing
• SEO and GEO
• Content distribution and paid media

Good Choice For

Developer tools, infrastructure products and technical B2B companies.

9. Vezert

Vezert is primarily a B2B and SaaS web design company. It builds landing pages, corporate websites and web portals, with technical SEO included in the development process. Its current site highlights semantic HTML, structured data, Core Web Vitals and multilingual SEO. That means it is not a conventional link building agency. It belongs on this list mainly for businesses where the site, technical foundation and search strategy need to be improved together.

Services Offered

• B2B and SaaS web design
• Technical SEO
• SEO-ready site architecture and performance work

Good Choice For

SaaS and B2B companies rebuilding a website with search in mind.

How to Choose a Link Building Agency

Start with the markets you actually want to reach, not the agency`s home country.

A company selling software in Europe may need links from industry publications in Germany, France and the UK. An ecommerce brand may care more about product reviews, editorial mentions and relevant niche websites. A B2B company may need links that also put its experts and research in front of the right audience.

Ask the agency how it finds prospects. You should know what makes a site suitable before links start appearing.

It is also worth asking about content. Is the agency writing original material for each placement, adapting content to the publication, or sending the same format everywhere?

Finally, look at the report. A useful report should show where links were earned, which pages they point to, and why they were selected. A backlink count alone is not enough.

Conclusion

These agencies cover a wide range of link building and SEO needs.

Motherlink is built heavily around backlink acquisition, while Ethical SEO has a strong SaaS and digital PR angle. Blu Mint and Brookelake are broader growth agencies. Snoika connects link building with search visibility and digital PR across international markets.

Suvy Marketing OÜ is a broader digital options. Wizard on Demand is a much more specialised choice for technical companies, while Vezert is mainly focused on B2B and SaaS websites rather than outreach itself. LocalRank-SEO also belongs in the broader SEO category rather than the pure link building category.

That difference is important. If you only need backlinks, look for an agency where outreach is a major part of the service. If your site also needs technical SEO, content, website work or a wider growth plan, a broader agency may make more sense.
