This case study shows how a controlled link-building strategy using outreach, a proprietary PBN, and tier-2 links delivered steady growth in commercial visibility and helped outperform competitors in a highly competitive niche.
The client is a licensed online casino operating in the LatAm market. Under NDA, we do not disclose the brand, domain, or exact GEOs, but we can demonstrate the working logic and SEO results that are directly influenced by the backlink profile.
Budget split:
We joined an already defined SEO strategy and were responsible exclusively for link-building execution. All priority pages and clusters had been identified in advance.
Our task was not just to increase the number of links, but to build a controlled link-building system with predictable pacing, stable indexation, minimized losses, and continuous quality control of donors.
It was critical that each link looked natural in its environment and blended seamlessly into the overall backlink profile.Donor selection was based on strict quality criteria. We worked only with websites that met the following requirements:
For this project, we built a dedicated in-house PBN from scratch, tailored specifically to the client’s needs. Drop domains with clean histories were selected based on multiple risk factors.
Tier-2 links were used selectively—as a reinforcement tool for the most valuable tier-1 links and to stabilize their indexation. This helped “lock in” results and reduce long-term link loss.
We built an operational model that covered both placement control and link indexation management.
Particular focus was given to speeding up indexation to reduce the lag between publication and measurable impact.
A strong emphasis was placed on result preservation, not just link placement.
This approach helped avoid drops and loss of link equity, even in a highly competitive environment.

We clearly understand the realities of the iGaming niche: most casino review websites and mono-brand projects hold top positions primarily through aggressive link building. In such models, the sheer volume of backlinks often becomes the decisive factor, especially in the short term.
However, this project had a different objective. The goal was not to build a website “for a limited period,” but to develop a полноценный casino brand capable of competing consistently in SERP and maintaining positions over the long term.
That is why the strategy described in this case study was chosen: controlled link building with a strong focus on donor quality, relevant context, a managed anchor mix, stable indexation, and long-term result preservation.
This approach made it possible to combine the required level of scalability with the development of brand trust — both from search engines and from users.
As a result, we did not simply build links; we built a system that works for the brand and allows it to maintain competitive positions without constantly shifting into an aggressive growth mode.
Results were evaluated strictly based on SEO metrics directly affected by link building, without factoring in any on-page or content changes.

The project has the potential for further scaling and maintaining achieved positions without changing the core logic of the link-building strategy.
The current results create a solid foundation for continued growth across priority commercial clusters.
P.S.
We work with iGaming projects at different growth stages. In this case, our responsibility was link building only: outreach, PBN, tier-2, indexation control, and stability.
