1. The PPC basics that matter first
Amazon Sponsored Products are cost-per-click ads: you bid for opportunities to show an advertised product, and you pay when a shopper clicks. Amazon supports automatic targeting as well as manual keyword and product targeting. For a new advertiser, Sponsored Products are usually the simplest place to learn because the relationship between search, click, order and spend is comparatively direct.
The key distinction is between a keyword or target you choose and the search term the shopper actually typed. Search-term data is where you discover what is really producing sales. Amazon itself recommends using search-term reporting to identify customer searches and focusing top performers with more controlled manual targeting.
Start with evidence, not constant bid changes
A few clicks are not enough to prove that a keyword is bad. Give targets enough data to make a sensible decision and review them on a consistent schedule rather than reacting to every day.
2. A simple campaign structure
For many accounts, a practical structure separates discovery from control. Automatic, broad and phrase targeting can discover useful searches. Manual exact targeting gives you direct control over searches that have already demonstrated value.
Discover
Use automatic, broad, phrase or product targeting to learn how shoppers find the product.
Measure
Review spend, orders, sales and conversion at the target and search-term level.
Harvest
Move proven search terms into controlled manual targeting where appropriate.
Optimise
Adjust bids and exclusions using clear thresholds and guardrails rather than guesswork.
See the detailed Amazon keyword harvesting guide for the discovery-to-control process.
3. ACoS tells you about ads. TACoS tells you about the whole business.
ACoS is advertising spend divided by ad-attributed sales. It helps you judge advertising efficiency. TACoS is advertising spend divided by total sales, including organic sales. It helps you see how dependent overall revenue is on advertising.
Neither should be used in isolation. A campaign can have a high ACoS while supporting a launch, ranking or discovery objective. Conversely, an attractive ACoS does not automatically mean the account is growing profitably.

4. A beginner-friendly weekly PPC workflow
You need a routine you can repeat. A sensible weekly pass is:
- Check total sales, PPC sales, spend, ACoS and TACoS.
- Identify campaigns or targets spending without sufficient return.
- Find converting search terms that deserve more control.
- Check negatives and obvious duplication.
- Review bid changes against a defined target or rule.
- Confirm stock, conversion or listing problems before blaming advertising.
- Record what changed so next week's review has context.
The full process is in the Amazon PPC weekly review guide.
5. Common beginner mistakes
Changing too much at once
If bids, budgets, targeting and listings all change together, you cannot tell what caused the result.
Judging only by ACoS
ACoS is important, but total sales, TACoS, margin and product lifecycle provide the context.
Ignoring search terms
Campaign-level numbers hide the exact customer searches that are wasting spend or converting.
Automating before defining rules
Automation is safer when it applies a strategy you understand, with limits and a review step.
