Section 1: Understanding Lifetime Best ACOS

Most sellers focus on ACOS in short-term windows—last 30 days, Q1, a product launch. But these snapshots can be misleading. What really matters is your lifetime best ACOS—the lowest sustainable ACOS you’ve ever achieved while maintaining or increasing sales.

Why focus on lifetime best?

– It shows the true efficiency of your advertising over time 

– It aligns with long-term growth and profitability 

– It filters out seasonal spikes and short-term fluctuations 

– It gives you a clear benchmark to measure progress against

Using structured campaigns, detailed search term analysis, and dynamic bidding, we slashed their ACOS by over 50%, while increasing total sales by 3.2x. The result? Higher profitability and a scalable foundation for growth.
