The challenge
Organic fruit is a seasonal, high-trust product. Buyers search when harvest is on, compare farms on freshness and certification, and they often ask AI tools such as ChatGPT, Gemini and Google AI Overviews who to buy from. The farm needed profitable online orders, not just traffic, and could not afford wasted spend in a short season.

The Purple Circle playbook
Brand consultancy first
We began with a brand consultancy approach: what makes this farm different (organic practices, freshness, story), and which claims buyers trust. That positioning fed every ad, headline and landing page.
Intent-based search
Campaigns were built around buyer intent: ready-to-buy searches, gift and subscription queries, and local “near me” searches. Conversational queries, the way people now ask AI assistants, got their own ad groups.
Product-feed campaigns
A clean Merchant Center feed with clear titles, seasonal availability and pricing powered Shopping and Performance Max campaigns, so the right fruit appeared at the right time.
AI features with guardrails
We tested Google’s AI-driven search matching, such as AI Max for Search, with tight negative keywords and brand controls so broader reach did not turn into irrelevant clicks.
Clean data for Smart Bidding
Purchase tracking and enhanced conversions fed first-party data to Smart Bidding, which optimized toward conversion value, not clicks.
Weekly budget shifts
Every week, spend moved from weak terms and products to the campaigns producing revenue. In a short harvest season, speed matters more than a monthly report.

Conclusion
This project shows that a seasonal food brand can earn strong returns from Google Ads when positioning is clear, campaigns follow buyer intent, data is clean and budget moves weekly.

Purple Circle brings that model to brands that want measurable growth. Results vary by product, margin and season, so treat these figures as a benchmark, not a guarantee.
