Why Ongoing Optimisation Matters
Amazon PPC campaigns are not set-and-forget. Competition changes, customer behaviour shifts, and Amazon's algorithm evolves. A campaign that performs well today may degrade over months without attention. Regular optimisation keeps your advertising spend efficient and your return on ad spend healthy. The sellers who consistently optimise outperform those who set up campaigns and walk away.
Weekly Review Routine
Check your campaigns weekly for obvious issues. Look for keywords spending money without generating sales (pause or reduce bids). Identify keywords converting well that deserve higher bids or budget. Check your daily budget is not running out too early (which means you are missing afternoon and evening shoppers). These quick checks prevent waste and capture obvious opportunities.
Monthly Deep Optimisation
Once per month, do a thorough review. Download your search term report and analyse which actual customer search terms triggered your ads. Move high-performing search terms into exact match campaigns for more precise control. Add irrelevant search terms as negative keywords to prevent future wasted spend. Review your ACoS (Advertising Cost of Sales) by product and pause campaigns that are not generating profitable returns.
Keyword Strategy Evolution
Start campaigns with broad or phrase match to discover which search terms work. As data accumulates, graduate winning terms to exact match for precise targeting. Build negative keyword lists continuously — every irrelevant click costs money. Over time, your campaigns should become increasingly precise, targeting only proven converting terms with appropriate bids.
Bid Optimisation
Increase bids on keywords with good ACoS and room to scale (they are converting profitably but may not be showing at the top of results). Decrease bids on keywords with marginal ACoS (they are converting but barely profitably). Pause keywords that consistently spend without converting after sufficient data has accumulated (typically 20+ clicks with zero sales indicates the keyword is not working).
Seasonal Adjustments
Adjust budgets and bids around seasonal demand. Increase spend before your peak selling periods and reduce during slow periods. Q4 typically requires higher bids due to increased competition — plan your budget accordingly. After peak periods, review which seasonal keywords performed and note them for next year. Effective PPC management is iterative — each cycle of data and optimisation makes your campaigns slightly better than the last.
