SEO link building: links that actually
move your rankings up
Domain authority is one of the three pillars of organic search. Without link building, even the best content stalls on page 2. We build your link profile with rigor: only editorial backlinks, on sites with genuine organic traffic.
Talk about my link strategy →How an SEO link building campaign unfolds
Link building is simple to understand: every site that references you sends a vote of confidence to Google. The more votes come from credible, relevant sites, the more your authority grows. But it has to be done in the right order, with the right method. Here's ours.
Link building audit
Before we build a single link, we run an audit of your existing profile: number of backlinks, domain authority, quality of referring sites, anchor text used, any toxic links. Then we do the same for the competitors ahead of you. The link building audit reveals exactly the gap to close, and it's what drives the strategy.
Tailored link strategy
How many links, at what pace, to which pages, with which anchors: everything is planned. An effective link building strategy first targets the pages that generate revenue, identified through keyword research, with a natural anchor text distribution. This is what separates thoughtful SEO link building from buying backlinks in bulk.
Selecting referring sites
Every site is checked manually: real organic traffic, topical relevance to your business, editorial quality, clean history. We rule out link farms and networks of sites created solely to sell links. One good link is worth more than ten mediocre ones.
Publishing the links
Articles are written, optimized, and published on the selected sites, with a contextual link woven naturally into the content. You approve every placement before publication: total transparency on where each link points and why.
Tracking and adjustments
We monitor link indexing, the evolution of your domain authority, and above all your rankings on the targeted queries. Pace and targets are adjusted based on results: link building is a lever you steer, not a cost you just absorb.
What our link building service includes
A serious link building campaign is more than just "buying backlinks." Here's everything that's included, from the initial audit to the final report.
Full audit of your link profile
A complete picture of your existing backlinks compared against the competitors ranking above you. You know precisely where you stand and how much effort is needed.
100% editorial links
Links embedded in real articles, published on sites with genuine organic traffic. No directories, no blog comments, no private link networks: link building that looks entirely natural to Google.
Manually vetted sites
Real traffic verified on Ahrefs, topical relevance, clean history. Every referring site is validated one by one before any publication. Quality always comes before quantity.
Natural anchor text strategy
A balanced mix of branded anchors, neutral anchors, and optimized anchors. This is what makes the profile look natural and removes the risk of an over-optimization penalty.
Content writing included
The articles hosting your links are written by our team: relevant, high quality, and aligned with your industry. The site that features you benefits too — that's what makes a good link.
Transparent reporting
Every link delivered is documented: URL, site authority, traffic, anchor text used, target page. You track the evolution of your authority and rankings month after month.
White hat or black hat link building: our line in the sand
Two schools of thought clash in link building. White hat plays by Google's rules: you earn links because a site with a real audience agrees to reference you in quality content. It's slower, more expensive, but the authority you build lasts.
Black hat cheats to move faster: hundreds of links bought from sites created solely to sell links, private networks (PBNs), automated spam. In practice, it can work for a few months, until Google spots the pattern and hands out a penalty that wipes out years of work, sometimes for good. Here's what we do, and what we'll never do with your site.
Our white hat link building
- Editorial links in real articles, on sites with genuine organic traffic
- Topics aligned with your industry
- A gradual, natural link acquisition pace
- Varied, balanced anchor text, without over-optimization
- Every link vetted by an SEO expert
The black hat we refuse to do
- Buying backlinks in bulk from $5 link farms
- Private blog networks (PBNs) created solely to sell links
- Mass link exchanges and artificial link schemes
- Over-optimized anchor text repeated across dozens of links
- Comment spam, mass directories, widgets, and footer links
Why this level of rigor? Because a Google penalty for artificial link schemes can wipe out years of work in a single update. Natural link building builds durable authority — the kind no one can take away from you.
What does quality SEO link building cost?
The cost of link building depends on the authority of the referring sites, the competitiveness of your market, and the volume of links needed. Here are the typical ranges for quality editorial link building.
| Package | Indicative budget | What's included |
|---|---|---|
| Single editorial link | €80 to €350 / link | Depending on the authority and traffic of the referring site |
| One-off link building campaign | €800 to €2,500 | A package of editorial links over 2 to 3 months, strategy and reporting included |
| Ongoing monthly link building | €500 to €1,500 / month | Gradual acquisition, built into an overall SEO strategy |
On link building platform comparisons, you'll find links for $5 or $10. At that price, they come from link farms with no real traffic: at best they're useless, at worst they expose your site to a penalty. A good link costs more because it's published on a site with real value — and that's precisely why it works.

Frequently asked questions
What is link building in SEO and how does it work?
Link building means earning links (backlinks) from other websites to your own. Each link acts as a vote of confidence in Google's eyes: the more credible sites reference you, the more your authority grows, and the higher your pages rank in search results. It's one of the three pillars of SEO alongside technical health and content.
Why is link building so important for SEO?
Because when content quality is equal, authority is the tiebreaker. Google ranks pages based on both relevance AND popularity. Without backlinks, even excellent content plateaus on page 2 behind competitors with more citations. The importance of link building for SEO shows up on nearly every competitive query: the top results almost always have the strongest link profiles.
How do you do quality link building?
Three rules: target sites with genuine organic traffic and a topic close to yours, favor links woven naturally into editorial content, and keep a gradual acquisition pace with varied anchor text. Quality SEO link building takes time and selectivity — exactly what $5 links don't offer.
Is buying backlinks risky?
Buying links in bulk from low-cost platforms or link farms, yes: Google penalizes artificial link schemes, and a penalty can wipe out years of work. On the other hand, selective editorial partnerships on quality sites with relevant content remain standard market practice when done intelligently and gradually.
What's the difference between white hat and black hat link building?
White hat link building follows the spirit of Google's guidelines: earned editorial links, quality sites, a natural pace. Black hat link building cheats: private blog networks, hidden links, spam, mass over-optimized anchor text. Black hat can deliver fast results, but it exposes you to penalties that cost far more than what it earned.
What does an SEO link building service cost?
Expect €80 to €350 per editorial link depending on the authority and traffic of the referring site, €800 to €2,500 for a full one-off campaign, or €500 to €1,500 per month for ongoing acquisition. Be wary of $5 or $10 links: at that price, they come from link farms that do more harm than good. Ask for a quote tailored to your market.
What's the best tool for analyzing your link profile?
Ahrefs is the market standard for auditing a link profile: backlinks, authority, competitive comparison. Majestic complements it with its trust metrics (Trust Flow), and Google Search Console gives you Google's own official view of your inbound links, for free. The ideal approach is to cross-reference these sources, which is what we do in every link building audit.
Link building or content marketing: which should you prioritize?
The two complement each other; they aren't in competition. Content attracts and converts, link building gives it the authority needed to be seen. Excellent content with no links stays invisible on competitive queries, and links pointing to mediocre content convert no one. The right sequence: a technically sound site, solid content, then link building as an amplifier.
