I started working with a client in the car rental niche (Sixt) in April 2024. At that time, their campaigns were spending about $22.5K/month, generating only 168 conversions, with a high $133 cost per conversion and a low 1.2% conversion rate.

Campaign Restructuring

I completely restructured their campaigns with the following strategies:

• Focused on high-intent keywords.
• Wrote powerful ad copies with strong CTAs.
• Set up advanced bidding (Target ROAS / Max Conversions).
• Fixed tracking to measure true ROI.
• Added negative keywords to reduce wasted spend.

The Results

Within just a few months, I scaled their account from $22.5K/month to over $1.81M in total ad spend while maintaining profitability.

✅ Conversions skyrocketed from 168 → 16,400+

✅ Cost/Conversion dropped from $133 → $111

✅ Conversion Rate more than doubled (1.2% → 2.79%)

Basically, these optimized Google Ads campaigns turned the client into a multi-million dollar business performer.

Summary

I scaled a car rental client from $22.5K/month spend with 168 conversions (CPC $133, CVR 1.2%) to over $1.81M in total spend, generating 16,400+ conversions. I restructured campaigns, targeted high-intent keywords, wrote strong CTAs, set up advanced bidding, fixed tracking, and added negatives. Results: CPC dropped to $111, CVR rose to 2.79%, and revenue crossed $1M+ with profitable scaling.
