At MGID, we’re constantly improving our tools to help advertisers achieve sustainable performance at scale. One of our most powerful solutions, CPA Tune, is leveling up again, and we’re excited to announce it’s now fully available for search feed campaigns.
With this update, affiliates and performance marketers can apply AI-powered, automated bidding to not only native campaigns but also high-intent search traffic. Early results show impressive ROI uplift and stable CPAs.
A Quick Refresher: CPA Tune Explained
CPA Tune is MGID’s AI-driven bidding algorithm that optimizes towards a target CPA while still operating on a CPC model. Instead of chasing clicks and hoping for conversions, the algorithm:
- Predicts conversion likelihood in real time thus buying only relevant traffic;
- Adjusts CPC dynamically based on user behavior and competitive landscape;
- Continuously optimizes to hit (and often beat) the target CPA with positive ROI.
The result is smarter budget allocation, less manual oversight and more conversions.
AI Optimization for Search Feed Campaigns
Search feed traffic offers high intent; however, it traditionally comes with tighter margins and more manual control. CPA Tune changes that:
- Automated buyouts: Manual bidding is not required.
- Dynamic CPC adjustments: Ensures spend is directed toward the most promising traffic.
- Granular efficiency: Each traffic opportunity is evaluated individually.
Early results are strong: advertisers report ROI uplift ranging from 30% to 80%, and thanks to granular inventory filtering, campaigns maintain higher volumes at stable CVRs. Plus, the model is fully aligned with Google’s latest RSoC standards, supporting all major search feed types like AFD and RSoC.
Best Practices for Search Feed with CPA Tune
While CPA Tune does the heavy lifting, a few simple steps can help unlock maximum performance:
- Keep no more than 10 creatives active at a time.
- Regularly refresh ads — retire underperformers, add fresh creatives.
- Set target CPA 15–20% below actual payout.
- Launch with a $100+/day budget, and let the first $200–300 run at breakeven. This gives the model time to learn.
- Check campaign performance 1–2 times per day: if margins are strong, increase target CPA; if margins are tight, decrease target CPA.
