Project Overview
Biggerz.com is a crypto casino platform going after one of the toughest niches in SEO - online gambling. The site offers cryptocurrency-based casino games and competes with some very well-established brands that have been building their online presence for years. We started working with them in October 2025. At that point, their domain had almost no authority, with DR 10 and 118 referring domains. The goal was simple: build a backlink profile strong enough to actually compete in search.
Goal
When Biggerz.com came to us, they wanted to show up in Google for competitive crypto casino keywords. So we set clear targets from day one: • Push Domain Rating from DR 10 past the DR 30 mark • Grow the number of websites linking to them (referring domains) • Only build links from real casino and prediction market websites • Every linking site had to meet minimum standards: DR 20+, at least 2,000 monthly visitors, and gambling relevance
Solutions
We kept the strategy focused. In a niche like crypto gambling, a handful of great links beats hundreds of weak ones, so every decision was about quality and relevance, not volume.
Only Relevant Sites, No Exceptions
Every link we built came from a casino or prediction market website. Google pays close attention to where links come from in gambling-related niches, so keeping everything topically relevant was non-negotiable. Each link we placed directly told Google: other trusted gambling sites vouch for Biggerz.com.
Strict Site Quality Standards
Before reaching out to any site, we checked the DR, monthly organic visitors, and a clear focus on casino or gambling content. If a site didn't pass all three metrics, we moved on.
Balanced Anchor Text
We mixed up the anchor text across all placements: some branded (using 'Biggerz'), some generic ('online crypto casino'), and some using a URL.
Steady, Consistent Outreach
We built links at a steady pace throughout the five months. This matters because sudden spikes in backlink growth can look unnatural and attract the wrong kind of attention from Google, especially in gambling, which is a closely watched category.
Results
Five months. One niche that's notoriously hard to build links in. Here's what we achieved for Biggerz.com.
Before the campaign, Biggerz.com had 31 keywords ranking in Google's top 10. That number has grown to 42, a 35% increase. As domain authority climbed and more relevant sites linked back to them, pages that were sitting just outside the top results moved up into positions where they actually get clicked.
When we started, Biggerz.com was bringing in 2069 monthly organic visitors. Comparing that to our most recent data, the site now receives 45731 monthly visitors. That is a 2111% increase. The growth came directly from the authority gains built through niche-relevant backlinks, which gave key pages enough weight to start ranking for terms they previously had no shot at.
Biggerz.com started at DR 10, a score that makes you basically invisible in Google's eyes when you're up against crypto casino brands at DR 50, 60, or even 70+. Five months later, they're at DR 37.
That's not just a number. DR 37 means Google now sees Biggerz.com as a site with real authority. It means backlinks are passing more weight. It means the homepage has a genuine shot at ranking for terms it simply couldn't touch before. In a niche where domain authority is everything, going from 10 to 37 in five months is the kind of jump that changes what's possible for the next 12 months of SEO.
How did we get there? Every link we built came from a real casino or prediction market site with a minimum DR of 20, 2,000+ monthly visitors, and gambling-relevant content. No shortcuts. No low-quality placements diluting the profile. Just 451 solid backlinks from 334 new referring domains, all pointing to one domain and pushing that DR up consistently, month by month.

DR doesn't move without referring domains behind it. We grew Biggerz.com's referring domain count from 118 to 452, that's 334 new websites now linking to them. Google treats each unique linking domain as a separate vote of confidence. Going from 118 to 452 votes means the signal is now much harder to ignore.
