Temu and Shein's Stop-Start Ad Spend Is Whipsawing Your CPCs

Temu and Shein are spending $10-15 million per day on Google Shopping, then pulling out overnight when tariff news threatens their business model. This stop-start pattern inflates and deflates CPCs across every category they compete in, creating 40%+ week-over-week swings.

Home and kitchen sees the highest CPC volatility at plus or minus 45%. Fashion and accessories at plus or minus 50%. Beauty and personal care at plus or minus 35%. Electronics accessories at plus or minus 30%. Pet supplies and specialty/industrial categories see minimal impact.

Switch from fixed CPC bids to Target ROAS or Maximize Conversion Value bidding on Google Shopping. Set your Target ROAS 15-20% higher than actual target as a buffer. Use dayparting to pause campaigns during peak-cost hours (9 AM to 6 PM EST when Temu concentrates spend). Set CPC alerts above your break-even threshold.

No. The volatility creates opportunities too. When Temu pulls out, CPCs drop 25-40%. Sellers who detect these windows can increase spend during low-CPC periods and capture market share at a fraction of normal cost. The key is monitoring CPCs weekly and using flexible bidding strategies.
