Rodi Boosts Lead Generation With AI-Generated Ads

We ran an A/B test with Meta Ads and Google Ads (Demand Gen) for the “Tires Without VAT” campaign, comparing AI-generated creatives to traditional ones. We saw improvements in both performance and results.

Challenge and Results

Rodi Motor Services is a network of workshops specializing in tires and full vehicle maintenance, with a strong presence in Spain, Portugal, and Andorra. They have over 180 locations and more than 2,000 team members.

The goal of this project was to test whether AI could actually improve campaign performance, with results that could be fully measured. We set up an A/B test comparing an AI-generated ad to a traditional ad, keeping investment and setup conditions the same.

We wanted to see if AI could drive more engagement and conversions while lowering the cost per acquisition, improving performance all the way from first contact to final purchase.

1

Setting Up a Solid A/B Test

We created two versions of the ad (AI vs. traditional) and a measurement framework to make sure any differences in results were due to the creative, not budget or setup changes.

2

Tracking Real Improvements

We tracked key lead-generation metrics, including CTR, CPC, CPA, conversion rate, and intent signals, like views and actions on the product page.

3

Testing Across Two Channels

The experiment ran on Meta and Google Demand Gen to make sure that the results held up across different platforms.

Lower Costs and Increased Sales on Meta Ads

The AI-generated ad reduced CPA by 31% and increased purchases by 45% compared to the traditional ad, all with a similar budget.

More Engagement Throughout the Funnel (Meta Ads)

AI content got 35% more views and 41% more “add to cart” clicks, proving that it could grab attention and drive purchase intent better.

Better Efficiency on Google Demand Gen

The AI ad had a 6% higher CTR, an 18% lower CPC, a 26% lower CPA, and an 11% higher conversion rate, proving it drove more qualified and profitable traffic.
