Link building agency - developyour SEO authority through backlinks

Good links make good references.

We build your backlink profile to strengthen your authority and make you a reference that Google and AI naturally cite.

Why is link building important in SEO?

  1. You strengthen the authority of your site

    Every quality external link pointing to your site is a trust signal for Google. Link building strengthens your Domain Authority and sustainably improves your ranking, without touching your existing content.

  2. You accelerate your rise in the rankings

    A strong link profile is the fuel for your SEO. You gain positions faster on competitive keywords, where content alone is no longer enough.

  3. You build a lasting web presence

    Unlike ads, backlinks work for you continuously. A link acquired today generates visibility for years. You're investing in an asset that appreciates over time, not an expense that stops as soon as you cut the budget.

Netlinking Methodology

Links that boost your authority

We build your link profile for the long term: relevant sources, consistent anchor texts, a natural progression in Google's eyes.

Method view
  1. Existing link profile audit

    We start by analyzing your existing profile: referring domains, source authority, anchor texts used, and any potential toxic links. We identify risks to address before building new links and prioritize gaps to fill.

  2. Strategy & Targeting

    We define the strategy tailored to your market: what types of links, what sources, and which pages to prioritize for strengthening. Each link built must serve a precise objective, reinforcing a pillar page, supporting a theme, or accelerating the ranking of a target query.

  3. Opportunity Identification

    We identify relevant sources for your sector: specialized media, authoritative blogs, quality directories, and potential partners. We only work with domains that have real authority, on topics consistent with your niche. No site networks, no PBNs.

  4. Editorial Placement

    We handle outreach, content creation, and placement negotiations. Each insertion is editorial: the link integrates naturally into quality content, on a legitimate source.

  5. Digital PR & Brand Mentions

    Beyond traditional links, we develop your editorial presence through: mentions in reputable media, interviews, opinion pieces, and citations in in-depth content. These signals strengthen both your brand authority and your domain authority, while also boosting your GEO visibility.

  6. Monitoring, Reporting & Iterations

    Each month, you receive a clear report detailing: links acquired, referring domains, the evolution of your domain authority, and the impact on targeted positions. We adjust the strategy based on the results and newly identified opportunities.

You can tell they have great taste, and above all, a real eye for detail on every screen. On top of that, the team is incredibly responsive and very experienced: they know both design and the technical side inside out. I’d recommend them without hesitation.

We’re very happy with the result, and the numbers speak for themselves. Sacha & Sandro are skilled, committed, conscientious, passionate, and they see things through to the end. I highly recommend them!”

What the FAQ?

What is a netlinking agency?

A netlinking agency helps businesses acquire quality backlinks from third-party websites to strengthen their domain authority in Google's eyes. Backlinks remain one of the most powerful ranking signals: a link from a high-authority site in your industry is worth far more than ten links from generic directories.

At Gemeos, netlinking is integrated into our SEO strategies as an authority lever. We don't sell link volume; we target qualitative editorial placements on relevant sites for each client's industry.

How does a netlinking strategy work?

A netlinking strategy unfolds in three phases. First, an audit of the existing link profile to identify strengths, weaknesses, and potential toxic links. Next, defining a target: what types of sites, what industries, what level of authority. Finally, link acquisition through various methods: guest posts, editorial partnerships, digital PR, or link insertion in existing content.

PhaseWhat happens
Audit of the existing profileAnalysis of current backlinks, detection of toxic links
Defining the targetTarget sectors, minimum authority level, types of sites
AcquisitionGuest posts, partnerships, digital PR, editorial placements
MonitoringTracking acquired links, detecting lost ones

What are the different types of backlinks?

Not all backlinks are created equal. The quality of a link depends on the authority of the linking site, its thematic relevance, its editorial context, and the link attribute (dofollow or nofollow).

Type of backlinkSEO valueHow to get it
Natural editorial linkVery highQuality content cited spontaneously
Guest post on a relevant siteHighContent pitched to publishers in the sector
Editorial partnershipHighCo-publishing agreement with a partner site
Digital PR / press mentionsHigh to very highMedia relations, original studies, proprietary data
General directoryLow to noneManual submission
Link bought on a PBNRisky, possible penaltyArtificial site networks

How to get quality backlinks?

Three methods work sustainably: producing content worth citing (studies, original data, reference guides), pitching guest posts to publications in your industry, and activating editorial partnerships with businesses complementary to yours.

Methods that seem quick (mass link buying, PBNs) generate short-term results but expose you to Google penalties that can wipe out months of SEO work in a few days.

MethodLink qualityTimeframeRisk
Citable content (studies, data)Very highLong termNone
Editorial guest postsHighMedium termLow
Editorial partnershipsHighMedium termLow
Digital PRVery highVariableNone
Buying links in bulkLowShort termHigh

What are the risks of a bad link building strategy?

The main risk is a manual or algorithmic penalty from Google. A manual penalty (triggered by a Google reviewer) can partially or totally deindex your site. An algorithmic penalty via Google Penguin updates devalues artificial links and can cause your rankings to drop overnight.

Practices that trigger these penalties include: buying links on artificial site networks (PBNs), massive link exchanges, over-optimized anchor text, and links from sites not thematically related to your business.

Buying links on a PBNManual or Penguin penalty, possible deindexing
Mass link exchangesAlgorithmic devaluation
Over-optimized anchors (exact match)Manipulation signal detected by Google
Links from off-topic sitesDevalued links, suspicious profile
Sudden spike in the link profileArtificial pattern detected

How to choose a link building agency?

The first sign of a good link building agency: it shows you examples of sites where it places links, with their real metrics (DR, organic traffic). An agency that only talks about "link volume" without mentioning the editorial quality of partner sites, run away.

Also check that it doesn't use PBNs (Private Blog Networks): a common practice in the industry, it generates short-term results but exposes you to irreversible penalties.

CriterionGood agencyRed flag
TransparencyShows partner sites with real metricsRefuses to reveal its link sources
Site selectionTopical relevance, high DR, real trafficLink volume without quality criteria
MethodsEditorial guest posts, partnerships, digital PRUse of PBNs or artificial networks
ReportingAcquired links verifiable in AhrefsOpaque reports without link URLs

How much does a link building campaign cost?

The cost of a link building campaign depends on the number of links targeted, their authority level, and the acquisition method. An editorial link on a high-traffic site in a competitive sector costs more than a guest post on a niche blog.

Type of serviceIndicative rangeWhat's included
One-off campaign (5 to 10 links)€1,500 to €4,000Site selection, writing, placement, reporting
Monthly link building retainer€800 to €2,500/month2 to 6 links/month depending on budget, ongoing monitoring
Digital PR (press mentions)€2,000 to €8,000/campaignCreation of citable content, media outreach

How long does it take to see results?

The first effects of a link building campaign are generally seen between 2 and 4 months after the links are acquired. Google needs time to crawl new links, evaluate them, and integrate them into its ranking calculations. The impact on rankings is rarely immediate, but it is lasting: unlike ads, an acquired link continues to pass authority as long as it is live.

TimeframeWhat we observe
0 to 4 weeksLinks are crawled and show up in Ahrefs
1 to 3 monthsAuthority starts flowing, slight DR increase
3 to 6 monthsVisible impact on the rankings of target pages
6 months and beyondConsolidated authority, compounding effects

How many backlinks are needed to rank?

There's no universal number. What matters is the gap between your link profile and that of your competitors on pages ranking in the first position for your target queries. For a low-competition query, 5 to 10 quality links might be enough. For an ultra-competitive query, leaders can have hundreds of referring domains.

The right approach: analyze the link profile of the top 3 positions for your target queries using Ahrefs, then build a strategy to achieve a comparable level.

Can you be penalized by Google?

Yes. Google penalizes sites that attempt to artificially manipulate their rankings through unnatural links. There are two types of penalties: manual penalties, applied by a Google reviewer and visible in Search Console, and algorithmic penalties, automatically triggered by updates like Google Penguin.

Type of penaltyTriggerConsequenceRemedy
Manual penaltyReport or Google reviewPartial or total deindexingLink disavow + reconsideration request
Algorithmic penalty (Penguin)Automatic Google updateRanking drop on target queriesLink profile cleanup + disavow

The best protection against a penalty: build a natural and diverse link profile from the start. A profile that resembles what a legitimate site naturally acquires (anchor diversity, source diversity, steady progression) won't trigger any red flags with Google.
