Case Study: How the AI Max Experiment Delivered 150% Revenue Increase

🚀 Results in a Nutshell

Instead of a lengthy intro, let’s start with the hard data. The experiment proved that automation, when combined with a strong foundation, can shatter expectations.

  • Total Performance Boost: 150% increase in conversion value.
  • Keyword Performance: €8,700.
  • AI Max Performance: €13,000.
  • ROAS: Consistently maintained at the target level of 5.

The Challenge: How to Scale What’s Already Working?

Our client had stable and profitable Search campaigns. While traditional approaches yielded solid results, we hit a “ceiling.” We were looking for a way to scale the campaigns further and uncover additional conversion potential that manually targeted keywords couldn’t capture.

The Solution: AI Max

We decided to test AI Max within a Search campaign.

The Process:

  • Campaign Selection: We chose the top-performing category, Search campaign, with sufficient historical data.
  • Goal Setting: We set a strict target ROAS of 5 to ensure efficiency.
  • Experiment Logic: We utilized AI Max to optimize bidding and find new queries outside the fixed keyword list, while the performance of the original keywords remained stable.

 Results

The experiment delivered a significant incremental lift. AI Max generated €13k more in conversion value compared to pure keyword targeting. A crucial finding was that the new technology didn’t “cannibalize” the performance of the original keywords

💡 Pro-Tips & Recommendations

If you’re planning a similar experiment, follow these principles:

  • Data is the key: Only enable AI Max where you have already gathered a high volume of conversions and a functional Smart Bidding setup. It’s a similar principle to transitioning from PLA to Performance Max.
  • Watch Your Search Terms: Stay vigilant during the first few weeks. The algorithm might “go wild” on your brand terms or competitor names. Regularly check reports and exclude irrelevant queries.
  • Prepare for the Future: Google has confirmed that DSA (Dynamic Search Ads) will eventually be phased out and integrated into AI Max. Testing now gives you a head start, so you won’t be caught off guard when this change becomes mandatory.

Conclusion

The AI Max experiment confirmed that, with the right setup, advanced algorithms can significantly outperform traditional methods. For clients seeking maximum performance, AI Max is no longer just an option—it’s an essential component of a modern strategy.
