Case Study: Cardioser Low Price | BG (joints) – $33 596 profit on Google Ads
The Cardioser Low Price offer belongs to the category of medical products for joints and was launched under the GEO Bulgaria. The product is targeted at an audience aged approximately 45+ who are experiencing joint pain and are actively looking for solutions online. Demand for such products is always stable, and in the spring and summer season, it grows even more due to increased physical activity. That is why this offer became attractive to arbitrageurs, and the use of Google Ads for nutra made it possible to get targeted traffic with high conversion potential.
An additional success factor was the novelty of the offer on the Bulgarian market. Users had not yet seen massive advertising for the product, so the level of trust was higher and competition was lower. The combination of seasonal demand, competent work with advertising tools, and high-quality landing pages made it possible to make Cardioser Low Price BG a top offer and ensure a stable and high profit.
Why the case turned out to be profitable: seasonality and novelty of the offer
In Bulgaria, the topic of joint treatment has a clear seasonality. After the spring, users switch to a more active lifestyle: gardening, sports, and tourist trips. This often provokes an exacerbation of back and knee pain, which is reflected in search queries. It is at this time that seasonal offers for arbitrage show increased results, as traffic comes with a clear intention and is cheaper than in the off-season. Here are some of the top searches in Bulgaria that Google records during this period:
"bolki в коленте" (pain in the knees);
"мазило за стави" (ointment for joints);
"болки в ставите лечение" (treatment of joints);
All of this creates a stable demand and the opportunity to generate conversions with high margins.
An additional success factor is the novelty of the offer itself. Cardioser Low Price BG has just entered the market, so it has become a new opportunity for Bulgarian websites. Fresh spring-summer affiliate offers always have a better CR, fewer moderation issues, and higher trust from the audience. That's why the offer quickly gained momentum and became one of the key solutions for arbitrageurs in the region.
What worked best: traffic sources, landing pages, and approaches
The success of the campaign was built on the right selection of traffic sources and precise work with creatives. Traffic arbitrage for medical products requires an audience with a clear intent, and was the Google Ads that allowed us to close this request. The use of several campaign formats allowed us to reach both hot and cold user segments. Here is a closer look at the traffic sources we used:
Search Ads. Focus on hot keywords: joint pain, joint treatment, gels and ointments. This approach resulted in a high CTR and maximum conversion.
Discovery. It worked effectively in conjunction with remarketing and native ads, which perfectly captures users.
Performance Max. He collected cold traffic and worked on look-alike audiences, scaling the campaign without a drop in ROI.
Landing pages also played a key role. The main one had an official style with certificates, doctors' advice, and reviews from real users, which built trust. The alternative landing page was more aggressive, with a direct offer, a discount timer, and a focus on quick solutions. Together, they created a flexible system for different audience segments, and both options showed the best results on mobile traffic among users aged 45+. This approach has cemented Cardioser as the top offer of the season.
Another important point was the adaptation of creatives to the local realities of Bulgaria. The adverts used clear language and images that the audience understood and associated with joint health. This helped to reduce the bounce rate and increase user confidence in the offer. The combination of correctly selected traffic sources, high-quality landing pages and localised creatives allowed us to maximise the offer's potential and maintain a stable profit throughout the campaign.

Why Google has made a profit
The effectiveness of the campaign is explained by a combination of the right traffic source and the specifics of the market itself. Google Ads for nutra allows you to work with users who already have a clear intention to solve a problem, so the quality of leads was high. In Bulgaria, competition is much lower than in Tier-1 GEO, which allowed us to keep bids at a comfortable level and maximise the return on investment. The main reasons for such good profitability include the following:
Targeted traffic with intent – users were actively looking for solutions to joint pain.
Low competition in Bulgaria compared to Tier-1 markets.
The combination of a new GEO and product created high interest.
Optimisation of campaigns: well-spaced keys, automation in Performance Max, A/B testing of creatives in Discovery.
Thanks to this approach, Cardioser was able to gain a foothold as a top offer in its niche. Proper optimisation of campaigns allowed not only to achieve short-term results but also to build a foundation for scaling, which is especially important in arbitrage in new markets.
Conclusions and tips for arbitrageurs
Entering the Bulgarian market with a new product in the field of joints proved that the strategy was right. The use of Google Ads made it possible to get targeted traffic with intent, which ensured stable conversions and a high level of upsell. It wasn't just a repeat of the old ligaments, but a full-fledged launch of a new product on a new GEO from a direct advertiser, which allowed us to gain a foothold in the market without being overwhelmed by competitors.
This approach proved that traffic arbitrage for medical products remains a profitable and flexible area, especially when it comes to fresh offers in regions with low competition. ROI of 30% and a profit of $33,596 proved that even with an average uprate of 36%, a campaign can bring significant results. For arbitrageurs, this case is a signal that new markets are worth testing, as it is there that stable and long-term earning opportunities can be found.
