Amazon Sponsored Products

Automatic Versus Manual Campaigns

Automatic campaigns let Amazon choose targeting based on the listing content. They require almost no setup and are the fastest way to discover which search terms actually convert.

Manual campaigns let you specify keywords or product targets with individual bids. More control, better efficiency, more work.

The standard approach uses both: an automatic campaign running continuously as a discovery engine, with converting search terms harvested into manual campaigns where they can be bid on precisely, and added as negatives in the automatic campaign so the two stop competing.

Match Types

Broad — widest reach, includes related terms and variations. Highest discovery, lowest efficiency.

Phrase — the phrase in order, with words allowed before or after. A reasonable middle position.

Exact — the specific term and close variants only. Tightest control, best efficiency, no discovery.

A common structure runs the same keyword across all three in separate campaigns with descending bids from exact to broad, so the tighter match wins the auction where it is eligible.

Product Targeting

Alongside keywords, Sponsored Products can target specific ASINs or product categories — placing your ad on a competitor's product page.

This works well where your product has a clear advantage over the target — better price, better reviews, a feature they lack. It works poorly when placed against superior competitors, where you pay to send traffic to a better option.

Select targets deliberately rather than using broad category targeting, which places ads against everything including products that outclass yours.

Negative Keywords

The most neglected lever. Without negatives, campaigns spend on search terms that will never convert — wrong size, wrong compatibility, wrong intent, competitor brand names you cannot win.

Review the search term report weekly and add negatives for anything with clicks and no sales at a meaningful threshold. This single habit does more for ACOS than most bid adjustments.

Bid Management

Amazon offers dynamic bidding — down only, up and down, or fixed — plus placement-level modifiers for top-of-search and product pages.

Start with dynamic down-only, which reduces bids when conversion is unlikely and cannot overspend. Move to up-and-down only once the campaign has consistent conversion data, since it will bid above your base for promising impressions.

Top-of-search placement typically converts best and costs most. Use the placement modifier deliberately rather than raising the base bid, which raises cost everywhere.

The Harvest Loop That Runs the Account

A working Sponsored Products account is a loop rather than a setup, and the loop is the same every week.

1. Automatic campaigns discover terms you would not have guessed. Their job is research, not performance, and judging them on ACOS misreads what they are for.
2. Pull the search term report and find terms that converted.
3. Promote those into an exact-match manual campaign where you control the bid.
4. Add them as negatives in the automatic campaign, so the two stop competing for the same query and you stop paying twice to learn the same thing.
5. Negate the spenders that never convert, which is where most wasted budget goes.

The step almost everyone skips is four. Without it, the automatic campaign keeps bidding on terms you have already graduated, and the account's own campaigns bid against each other — visible as rising cost on terms whose conversion rate has not changed.

Run it weekly at first, then fortnightly. The discovery slows but never stops, because the catalogue and the competition both keep moving.

Why the Listing Constrains the Advertising

Advertising on a retail platform is unusual in that the landing page is the product listing and you cannot design it freely. Everything downstream of the click is governed by the listing, which means ad performance is capped by things that are not the ad.

What actually determines whether the click converts: the main image, which must meet the platform specification and carries most of the decision; price relative to visible alternatives, since competitors appear on your own page; reviews and rating, which no bid adjustment can compensate for; availability, because an out-of-stock item should not be advertised at all and frequently is; and the fulfilment badge, which shifts conversion more than most creative changes.

The practical rule: fix the listing before raising the bid. A poor listing with a high bid buys expensive traffic that does not convert, and the reporting will describe it as a keyword problem.

And check the placement report. Top-of-search usually converts better and costs more; a placement adjustment is often a cleaner lever than a keyword-level bid change.
