Search arbitrage continues to evolve rapidly, with major shifts happening in 2025 that every affiliate marketer needs to understand. Tonic, one of the most respected search feed providers in the industry, sits at the center of this transformation as the market transitions from traditional AFD (AdSense for Domains) to the more advanced RSOC (Related Search on Content) model.

Whether you’re already running search arbitrage campaigns or looking to break into this lucrative vertical, understanding the differences between AFD and RSOC—and how Tonic fits into your strategy—is crucial for maximizing your ROI in today’s competitive landscape.

What is Search Arbitrage and Why Tonic Matters

Search arbitrage is a traffic monetization strategy where marketers buy traffic at a lower cost and redirect it to search result pages that generate higher revenue per click (RPC). The profit comes from the difference between what you pay for traffic and what you earn from clicks on the search results.

Tonic, based in Germany, has established itself as one of the most reputable search feed providers in the industry. Their platform offers both AFD and RSOC solutions, making them a critical partner for serious arbitrageurs looking to scale their operations.

The Current Market Landscape

The search arbitrage industry is experiencing its biggest transformation since inception. Google’s policy changes, effective March 2025, are forcing a fundamental shift from AFD to RSOC models. This isn’t just a minor adjustment—it’s reshaping how the entire industry operates.

Understanding AFD (AdSense for Domains): The Traditional Approach

What is AFD?

AFD, or AdSense for Domains, represents the classic search arbitrage model. With AFD, you purchase a domain and register it with your search feed provider. Instead of hosting your own content, the network hosts “relevant searches” with sponsored links.

How AFD Works with Tonic

  1. Domain Registration: Purchase and register domains with Tonic
  2. Traffic Direction: Send paid traffic to these parked domains
  3. Search Results Display: Tonic displays relevant search results and ads
  4. Revenue Generation: Earn revenue when visitors click on the sponsored results

AFD Advantages

  • Simpler Setup: No need to create content or landing pages
  • Faster Launch: Can start campaigns quickly once approved
  • Lower Maintenance: Minimal ongoing content requirements
  • Proven Track Record: Decade-plus history of successful campaigns

AFD Challenges in 2025

The AFD model faces significant headwinds:

  • Google Policy Changes: New policies require manual opt-in for parked domain advertising
  • Traffic Quality Control: Harder to control ad messaging and user expectations
  • Compliance Issues: Higher risk of policy violations
  • Limited Scalability: Increasingly difficult to get new domains approved

RSOC (Related Search on Content): The Future of Search Arbitrage

What is RSOC?

Related Search on Content represents the evolution of search arbitrage. Instead of sending traffic to parked domains, RSOC integrates search results directly into content-rich pages, creating a better user experience while maintaining revenue potential.

How RSOC Works with Tonic

  1. Content Creation: Develop valuable, engaging content pages
  2. Traffic Direction: Send visitors to these content-rich landing pages
  3. Integrated Search Results: Tonic embeds relevant search results within the content
  4. Enhanced Monetization: Multiple revenue streams including ads, affiliate links, and AdSense

RSOC Advantages

  • Better User Experience: 2-3 fewer clicks to reach relevant results
  • Higher RPCs: Often outperforms AFD in revenue per click
  • Multiple Monetization Options: Combine search results with affiliate marketing and AdSense
  • Future-Proof: Aligns with Google’s focus on quality content
  • Lower Compliance Risk: Content pages face fewer policy restrictions
  • Broader Traffic Source Compatibility: Works with more advertising platforms

RSOC Challenges

  • Complex Setup: Requires content creation and ongoing management
  • Tracking Complexity: More difficult to track compared to AFD
  • Higher Initial Investment: Need resources for content development
  • Market Saturation Risk: As more affiliates switch to RSOC, competition increases
