Top-10 lists do not help with this decision because they answer the wrong question. Provider models compared, five levels of scrutiny and four steps from enquiry to contract.
Compare providers on process quality, transparency and real link quality, not on rankings lists.
Any serious engagement starts with a look at your existing link profile, not with a package.
Building trust systematically through editorial placements and mentions beats sheer link volume.
Look for scalable processes and reporting that shows effect instead of counting links.
Three months of pilot say more than any proposal.
Looking for the right agency for link building is usually shaped by uncertainty. The market is full of promises that cannot be checked: guaranteed top-three positions, a hundred links a month, cheap backlinks in any quantity. Between those claims and sustainable link building sits a wide gap. Many companies end up with the wrong partner, lose budget and, in the worst case, risk a manual action.
This guide deliberately skips a ranking. A list of the best providers answers the wrong question, because the right choice depends on your goal rather than on a general order. What follows is about your goals, the provider types that fit them, and the criteria that make proposals comparable in the first place.
Phase 1: what you actually want to achieve
Before you contact an agency, the target picture has to stand. In practice we meet two fundamentally different approaches, and they call for different partners. Getting that assignment wrong leads to frustration every time.
Scenario A: quick impulses
You need movement in the short term for specific money pages or for a narrow keyword set.
Goal: direct ranking impulses, high frequency, fast visibility
Risk: recognisable patterns if the quality does not keep up
Fitting partner: specialists with fast delivery and scalable routines
Precondition: a clear off-page strategy that puts the links into a natural context
Scenario B: a sustainable build
You want to strengthen brand authority for the long run and establish a profile that stays stable through algorithm updates.
Goal: breadth, spread, editorial mentions and a natural curve over twelve to twenty-four months
Risk: slower results, in exchange for considerably more safety
Fitting partner: providers focused on digital PR, curated networks and advice
Precondition: the quality of the sources and their relevance to your industry count for more than the number
Our take: for short-term goals, agility and throughput count. If you want to secure market share for the long run, prioritise quality and transparency over speed. A good partner shows you both routes and says clearly which one fits your budget and your risk profile.
Phase 2: the provider landscape
Not every agency fits every goal. Four models dominate the German-speaking market. The overview below assigns example providers to them so that the differences in approach and scalability become visible. Prices are deliberately absent from the table: they depend so heavily on scope, market and format that any range would create more confusion than orientation.

Classic full-service agencies
Examples are Claneo, Working Digital and Suchhelden. Link building is one module here in an overall package of technical work, content and on-page. The advantage: everything from one source, less coordination, maximum synergy between content and links. The limit: link building is rarely specialised to the maximum, and on pure link campaigns the scaling hits its ceiling sooner. Sensible if you want to professionalise SEO as a whole and have little capacity internally.
Specialist link building agencies
Examples are SEO Profession and Netgrade. The focus lies almost entirely on link building, outreach, publisher management and tactics such as broken link building or guest articles. That brings more depth and more mature processes. The limit: you have to make sure yourself that the build interlocks cleanly with your content and your business goals. Sensible for targeted campaigns and where the demands on off-page depth are high.
Platform and technology approaches
Here SEO Galaxy and GetMentioned stand for two complementary routes. SEO Galaxy relies on automation, standardised routines and throughput, which suits link building that is meant to run as a scalable process. GetMentioned works as a marketplace for editorial placements, with a curated publisher network and openly visible data per domain. The two combine: standardisation for volume, curated placements for authority.
Digital PR agencies
The fourth route works through stories rather than through placements: data, studies and arguments are prepared so that newsrooms report on them of their own accord. That produces the strongest mentions, and it is the least plannable of the four. For a fixed need of so many placements per month it is the wrong tool.
Phase 3: the five levels of scrutiny
In a pitch many providers sound alike. They only become comparable across these five levels.
1. Link quality
Topical relevance: does the domain fit your industry, or is the authority metric only decoration?
Real traffic: does the site have visitors, or does it exist for SEO alone?
Editorial context: does the link sit in the body text of a relevant article, or in a list in the footer?
Natural profile of the source: does the domain’s own link pattern look organic or built?
2. Process and transparency
Documented outreach: is it shown how contacts come about and how personalisation works?
Quality check: are there clear criteria before publication?
Reporting: do you get domain, URL, anchor text, link attribute, metrics and publication date?
Commitments: are there agreements on delivery times, quality assurance and the handling of lost links?
3. Handling risk
Stocktake: is the existing profile including its legacy checked before anything is built?
Problematic links: how are spam, networks and cheap offers dealt with?
Anchor text strategy: is a natural spread of brand, URL, generic and partial-match anchors committed to?
Experience when it counts: is there experience with disavow files and with recovery after a manual action?
4. Communication and service
Is there a named contact, or only a ticket system?
How fast does an enquiry get an answer?
Do they advise proactively, or only deliver what was ordered?
5. Pricing model and economics
Transparency: are prices per link, per package or per month clearly named?
Flexibility: can the budget be aligned with the performance?
Ratio: does the expected benefit relate to the spend?
For orientation: for solid trade publishers, realistic prices usually sit at a few hundred euros per placement. Offers below a hundred euros per link are a warning sign, because editorial work cannot be done for that.
Phase 4: the path in four steps
Step 1: the enquiry
Send a short, standardised brief to five to eight providers: goals, markets, target URLs, budget range, accepted risk and preferred methods. The point is less the proposal than the test. Who understands the brief, proposes something that fits, and does not counter immediately with a standard package?
Step 2: the shortlist
Keep two or three providers who offer a stocktake instead of selling a package straight away, who disclose their routines and quality criteria, and who communicate realistic expectations, that is, probabilities rather than ranking guarantees.
Step 3: a three-month pilot
The pilot tests the process, not the volume. Agree a defined number of new referring domains, the quality criteria, a documented anchor mix and fixed reviews. The most telling part is how the provider handles the first problem.
Step 4: the contract
What worked in the pilot belongs in the contract. Four points should be settled explicitly:
Domain transparency at least at domain level, no black box
Handling of lost links: are they replaced, and within what window?
Ownership of the content: do the articles belong to you?
Data protection and processing agreements under the GDPR
Plus the two questions that often turn expensive at the end: who owns the placements once the engagement is over? And how do you get out without paying for a year?
How to weigh the answers
So the comparison does not end on instinct, a weighting helps. This distribution has worked for us. The exact numbers matter less than the fact that you set them before the conversations rather than after.
Publisher quality weighs heaviest, the handling of risk the least, because it only shows once something goes wrong.
In closing
There is no universally best agency, only the one that fits your goal, your budget and your maturity. If you need scale and efficiency, technology-driven approaches are the right place. If you are after editorial quality and a curated network, marketplace or PR models are. If you want to professionalise SEO as a whole, a full-service agency is. And if you need maximum depth in off-page, the specialists are.
In our experience the most common wrong call is not the wrong provider but no scrutiny at all. Set the grid beforehand and you hold different conversations and make a decision you can still justify in six months.

Common questions about choosing an agency
What do backlinks realistically cost?
The price depends on domain quality, relevance, format and effort. Editorially clean placements cost more and last longer. For solid trade publishers, a few hundred euros per placement is a realistic frame. There is no blanket answer, it always depends on the market and on your risk profile.
Is buying backlinks legitimate?
It is, if you pay transparently for research, content, outreach and placement, and the links come about in real, relevant surroundings. You recognise high-quality placements by traffic, topical fit, editorial context and a clean profile on the publisher side.
How do I spot a dubious offer?
By guaranteed rankings, fixed prices set without any knowledge of your target pages, missing domain transparency, and prices for which editorial work cannot be done. One more signal: when the question about indexing checks gets no concrete answer.
How long until link building affects rankings?
First effects often show after four to eight weeks, noticeable change rather after three to six months, depending on the competition and on your starting point. What decides it is continuity and natural growth in referring domains.
Which model fits when?
A classic agency fits when you want to outsource off-page delivery and strategy and on-page are strong internally. A technology-driven approach pays off when you want to standardise and scale heavily. A marketplace fits when you want to select yourself and see the data per publisher before budget moves.
Do I need an agency at all?
Not necessarily. If strategy, target pages and quality criteria stand internally and only the delivery is missing, a marketplace or a selective engagement is often enough. An agency pays off when the steering is to be handed over as well.
Which data should I supply before the start?
At a minimum: goals and time horizon, prioritised URLs and keywords, an export of the link profile from an SEO tool or Search Console, a competitor list, the budget range and notes on legacy issues such as earlier packages or an existing disavow file. The cleaner the basis, the more reliable the result.
