Google CSS Platform: 5 Days to Launch
How we built a complete Google CSS Partner comparison shopping platform from scratch in just 5 days using AI-accelerated development - a greenfield project turning weeks of work into days.
The Challenge
Our marketing team needed a Google CSS (Comparison Shopping Service) platform to unlock reduced CPCs on Google Shopping ads. This was a greenfield project - built entirely from scratch with no legacy constraints. While off-the-shelf solutions existed, we wanted:
- Full control over the platform and data
- Custom fit for our specific requirements and workflows
- Ability to integrate multiple affiliate feed sources
- A genuine comparison experience meeting Google's CSS Partner requirements
Traditional development would have taken weeks. Using AI-accelerated engineering, our technical team delivered the complete platform in just 5 days.
