What to do
Audit the last 60 to 90 days of data quarterly

Key takeaways

  • Audit 60 to 90 days of data against break-even ACoS for each product, not one account target.
  • Wasted search terms, converters stuck in auto and unbacked placement boosts are the usual leaks.
  • Finish with TACoS to check whether ads are building total sales, then fix the biggest items first.

What does an Amazon PPC audit find?

Audits tend to find the same handful of problems: search terms that spend without selling, converting terms stuck in automatic campaigns, one ACoS target applied to products with very different margins, bids that ignore placement data, budgets that run out on the best campaigns while weak ones spend freely, and ads running into stockouts. Each one is fixable, and the fix is usually a structural change, not a bid tweak. The goal is a list of actions ranked by money at stake.

What data to pull before you start

Use a 60 to 90 day window so results are not distorted by one event, and note any Prime Day or Q4 days inside it. Leave out the most recent few days, because orders from late clicks may not be attributed yet.

  • Targeting report and placement report
  • Campaign and advertised product reports
  • Business Reports for total sales and sessions
  • Product costs and fees for margin by ASIN
  • Brand Analytics Search Query Performance, if brand registered

Steps 1 and 2: goals, margins and structure

Start with economics. For each advertised product, calculate break-even ACoS, the profit margin before ad spend, and write down the product's goal: launch, growth, profit or defense. Without this, there is nothing to audit against. Our guide to a good ACoS for Amazon shows the calculation.

Then check structure. Each campaign should have one goal, ad groups should hold products of similar price, and branded, generic and competitor terms should sit in separate campaigns. Amazon itself advises grouping products by price range and conversion, because bids apply to every product in an ad group. Compare your setup with our Amazon PPC campaign structure template.

Steps 3 to 5: wasted spend, search terms and negatives

Sort the search term report by spend and filter for terms with no orders. Amazon suggests judging a term after at least 20 clicks, so terms past that with no sales are candidates for negative exact or phrase. Add up their spend: this is usually the clearest number in the audit. Then sort the other way. Search terms with orders at or below target ACoS that live only in automatic or broad campaigns should move into exact match with their own bids, and be added as negatives where they came from so campaigns do not compete.

Finally check the negatives you already have. Overly broad negative phrases can block good traffic, and missing brand negatives in generic campaigns hide weak results behind cheap branded sales.

  • Terms with 20 or more clicks and no orders
  • Converting terms not yet in exact match
  • Same term targeted in several campaigns
  • Negatives that block converting traffic
  • Brand terms leaking into generic campaigns

Steps 6 and 7: bids and placements

Compare each target's actual CPC with what it can afford: average order value times conversion rate times target ACoS. Targets paying more than that are buying losses. Check bid strategies too: dynamic bids up and down can raise bids on likely converting clicks, so it belongs on proven exact terms with margin, not discovery campaigns. Then read the placement report. Amazon allows placement adjustments of up to 900% for top of search, rest of search and product pages; any adjustment should be backed by better conversion in that placement. Our Amazon PPC bidding strategies and Amazon CPC guides cover the rules.

Steps 8 and 9: budgets, listings and stock

Look at which campaigns run out of budget and when. Profitable campaigns that stop by mid-day are leaving sales behind; unprofitable ones that never run out are taking budget they should not have. Amazon notes daily budgets are not paced, so a campaign can spend its budget early.

Then check what the ads point to. Ads only run while a product is in stock and winning the featured offer, and a listing that converts poorly makes every click expensive. Amazon's best practice guide suggests at least five reviews, a 3.5-star rating or higher, four or more zoomable images and three or more bullets. Flag ASINs with low conversion before blaming bids, and check upcoming stock so ads do not run into a stockout. Our Amazon conversion rate guide helps.

Step 10: TACoS and the whole business

The last step asks whether ads are helping overall. TACoS is total ad spend divided by total sales. Plot it by month next to total sales and organic sales. Falling or stable TACoS with rising total sales means ads are building demand; rising TACoS with flat sales means ads are buying sales the listing cannot hold on its own. Also compare branded and non-branded ACoS separately. Our ACoS vs TACoS guide explains how to read the trend.

Turning audit findings into an action plan

Rank every finding by monthly spend or sales at stake and fix the biggest first. Most audits produce three groups of actions. Make changes in batches and let them run two weeks before judging, as Amazon recommends, so you can tell which change did what. Our routine for how to optimize Amazon PPC keeps the account clean after the audit.

  • This week: negatives for wasted spend, pause losing targets
  • This month: move converters to exact, fix bids and placements
  • This quarter: restructure campaigns, reset targets from margin

How often should you audit Amazon PPC?

Run a full audit every quarter and after any big change: a price or fee change, a new product line, a major event, or a sudden jump in ACoS. Between audits, a weekly search term review and a monthly target check catch most problems early. If an outside view would help, our guide to questions to ask an Amazon PPC agency shows what a good audit should cover.
