Challenge: Campaigns suffered from high ACoS due to irrelevant and underperforming search terms.
Action: Paused low-performing keywords and ASIN targets, applied negative targeting across Broad, Phrase, and Auto campaigns.
Result: Reduced ACoS and improved ROAS within a short period.

Case 2

Challenge: High-potential keywords were not getting enough traffic.
Action: Increased bids and budgets on top-performing targets, strengthening visibility across Sponsored Products and Sponsored Brands.
Result: Boosted sales in core categories while maintaining ACoS within KPI.

Case 3

Challenge: Auto campaigns were generating clicks without conversions.
Action: Analyzed search term reports, added negative keywords, and reallocated budgets toward higher-converting campaigns.
Result: Increased CTR and improved conversion rate significantly.

I can provide more detailed descriptions of these case studies, including the product specifics, in a personal discussion.
