The single biggest driver of PPC waste on Amazon is poor campaign structure. Sellers running one auto campaign per product with a single budget cannot control where their spend goes, cannot isolate what is working, and cannot scale without proportionally increasing their ACoS.

Good campaign structure gives you granular control: you know exactly which keywords are driving revenue, which match types are performing, and where to allocate your next pound of ad spend. This guide explains the framework used by professional Amazon PPC agencies — and how to implement it for your account.

The Building Blocks: Campaign Types

Amazon Sponsored Products offers two fundamental campaign types:

Both types are necessary. Auto campaigns are your keyword discovery engine. Manual campaigns are where you scale profitable terms with precision.

Match Types Explained

Match TypeHow it worksExample keywordExample triggering search
BroadAds show for searches containing your keyword words in any order, plus variations, synonyms, and related termsgarden hose reel“hose storage reel for garden”
PhraseAds show for searches containing your keyword as a phrase, in order, with words before or after"garden hose reel"“retractable garden hose reel 30m”
ExactAds show only for searches that exactly match your keyword (or very close variants)[garden hose reel]“garden hose reel”
Which match type should you use?

Use all three — but for different purposes. Broad and Phrase match for discovery and reach. Exact match for scaling your best-converting terms with the highest bids and tightest control. Running all three match types for the same keyword in separate ad groups lets you compare performance and reallocate budget where it performs best.

The Professional Campaign Structure

Here is the framework used by agency-managed accounts. It uses Amazon’s portfolio feature to organise campaigns by product or product group:

Portfolio → Campaigns → Ad Groups

📚 Portfolio: [Product Name / ASIN Group]
SP — Auto (Discovery) SP — Manual Broad SP — Manual Phrase SP — Manual Exact SP — Product Targeting
For brand-registered sellers, add:
SB — Headline Search (Brand) SB — Keyword Targeting SD — Audience Retargeting

Each campaign has a single ad group with a focused set of tightly related keywords. One campaign, one ad group, one theme. This is the critical discipline: mixing different keyword themes in one ad group destroys your ability to analyse performance and optimise bids independently.

The Auto-to-Manual Pipeline: How Discovery Works

The most important process in structured PPC management is the auto-to-manual pipeline. It works like this:

  1. Run an Auto campaign at a moderate bid (say £0.60–£0.80) with a daily budget of £10–£20
  2. After 2–4 weeks, download the Search Term Report from Advertising → Reports
  3. Identify winners: search terms with 5+ orders and acceptable ACoS. These are your harvested keywords.
  4. Add winners as Exact match in a new manual campaign with a higher, dedicated bid
  5. Add winners as negatives in the Auto campaign — this prevents the auto campaign from competing with your higher-bid manual exact campaign for the same term
  6. Identify losers: terms with significant spend and zero conversions. Add these as negatives in the Auto campaign immediately.
  7. Repeat weekly as the Auto campaign discovers new terms
Why add harvested terms as negatives in auto?

If you don’t, both campaigns compete for the same impression. Your manual exact campaign has a higher bid and wins most of the time — but the auto campaign still occasionally fires on that term, splitting data and wasting budget. Negating in auto forces all traffic for that term through your controlled exact campaign.

Budget Allocation Framework

For a newly structured account, a starting budget split across campaign types:

40%
Manual Exact

Your highest-converting, most controlled campaigns. Proven keywords only. Highest bids justified.

30%
Auto / Discovery

Feeds new keywords into the pipeline. Lower bids acceptable. Needs regular negative keyword pruning.

30%
Broad & Phrase

Reaches broader search queries. Provides data on variations. Feeding ground for exact match promotion.

This is a starting point, not a fixed rule. As exact match campaigns mature and prove consistent ROI, shift budget toward them and reduce auto spend. On new product launches, weight auto higher (50–60%) until you have enough data to populate manual campaigns meaningfully.

Ad Group Structure: One Theme Per Group

Within each manual campaign, each ad group should contain one tight keyword theme. For a garden hose reel:

Separate ad groups allow separate bids per theme. If “retractable hose reel” converts at 30% and “hose storage” converts at 8%, you can bid £1.20 on the first and £0.35 on the second. Mixed into one ad group with a shared bid, you would over-bid on low performers and under-bid on high performers simultaneously.

Negative Keywords: The Most Underused Tool

Negative keywords prevent your ads from showing on irrelevant searches. They are the primary tool for reducing wasted spend. Two levels:

Build a negative keyword list from day one

Before launching any campaign, add an initial negative keyword list based on obvious irrelevancies. Review your Search Term Report weekly and add any zero-conversion terms with spend over £3–5. Within 60 days, a well-maintained negative keyword list typically reduces wasted spend by 15–25% of total budget — money that can be redirected to your best-performing exact match campaigns.

Naming Convention: The Discipline That Scales

When you manage one product, naming does not matter much. When you manage 20 ASINs with 5 campaigns each, poor naming creates chaos. Use a consistent format from the start:

[Product Code] — [Campaign Type] — [Match Type / Targeting] — [Date Created]

For example:

This makes it immediately clear what each campaign is, what product it covers, and when it was created — which matters when you are diagnosing performance changes months later.

The Weekly Optimisation Routine

Structure is only the foundation. The campaigns need regular attention:

  1. Monday: Pull Search Term Reports. Add converting terms to manual exact. Add wasted-spend terms as negatives.
  2. Wednesday: Review bid performance. Raise bids on keywords with ACoS < target. Lower bids on keywords with ACoS > 2x target.
  3. Friday: Review budget pacing. Any campaign hitting its daily budget cap before end of day? Increase budget or shift from underperforming campaigns.
Set and forget kills performance

Amazon PPC is not a “set and forget” channel. The auction is dynamic — competitor bids change, seasonal demand shifts, new products enter the category. Campaigns left unmanaged for 4+ weeks consistently decay in performance. Weekly optimisation is the minimum cadence for competitive categories.
