To reduce your TACoS from 18% to 10% while increasing sales, focus on boosting organic orders and improving ad efficiency.
Start by cutting spend on high-ACoS or low-performing keywords, and scale those with strong ROAS and ranking potential. Optimize your product listings (images, titles, reviews) to improve conversion rates and organic ranking. Shift more traffic to branded and exact match keywords, and consider using external traffic (email, social) to lift sales without increasing PPC spend.
With consistent optimization, you can realistically reach 10% TACoS in 30–60 days, depending on how quickly your organic visibility grows.
