The old way of doing PPC, with simultaneous bid adjustments and campaign launches, is ineffective for scaling and optimizing.
The new way of doing PPC focuses on one goal at a time, either scaling or optimizing for profitability.
Understanding the funnel is crucial, as PPC is interconnected with click-through rate and conversion rate.
Data analytics plays a vital role in PPC, helping identify profitable search terms and optimize campaigns.
Trustworthy data is essential, as Amazon's attribution and metrics may not always be accurate.
