2️⃣ Campaign Structuring for Scalability

We built single-ASIN campaigns and product targeting ads to control budgets and boost top-performing SKUs individually.
Actions:

  • Launched Auto + Manual campaigns
  • Used Product Attribute Targeting (PAT) to target competitor ASINs
  • Prioritized high-margin SKUs for increased ad push

We optimized bids weekly, increasing bids on high-CTR and high-conversion keywords while pausing or reducing low-performing ones.
Actions:

  • Used dynamic bidding (down only) to control CPC
  • Leveraged placement adjustments for Top of Search

4️⃣ Negative Keyword Implementation

To reduce wasted ad spend, we continuously added negative keywords based on search term performance.
Actions:

  • Added irrelevant search terms as phrase and exact negatives
  • Blocked high-impression, zero-sale keywords

5️⃣ Performance Monitoring & Iterative Scaling

Our team monitored KPIs daily and adjusted strategy every 7 days.
Actions:

  • Analyzed ACOS, CTR, CVR (Conversion Rate) trends
