Not Every Amazon ASIN Should Be Treated the Same in PPC

A common mistake in Amazon accounts is treating every product the same inside PPC.

Same campaign structure. Same match types. Same bids. Same budget. It's clean, it's easy to build, and it produces mediocre results in exchange for the simplicity.

Not every ASIN needs the same treatment. Some products convert well and respond quickly to more visibility. Others struggle to convert and will continue to struggle regardless of how much ad spend you throw at them. Treating them all the same wastes budget on the ones that don't convert and starves the ones that do.

The three types of ASINs in almost every account

Look at your catalog by product-level conversion rate over the past 90 days. You'll almost always see three tiers.

High-converting ASINs.

These are the products that convert at or above category average with any reasonable amount of traffic. Buyers see the listing, understand the value, and buy. These products deserve strong ad coverage, higher bids on proven keywords, and expanded campaign coverage into related terms. If you're not overweighting your spend toward these ASINs, you're leaving revenue on the table.

Average performers.

These convert acceptably but not exceptionally. They usually have a fixable listing issue, a slight price disadvantage, or a review gap. Increasing ad spend on these before fixing the underlying issue produces diminishing returns. Get the listing right first, then scale.

Low-converting products.

These convert well below category average even with quality traffic. More ad spend doesn't fix the problem. Usually the listing, price, or offer needs meaningful work before ads make sense. Sometimes the product itself isn't category-competitive and no amount of Amazon effort will change that. Either way, PPC is not the lever.

Why product-level allocation matters

If you run a single campaign structure across a catalog of thirty ASINs, your budget flows toward whichever products get the most impressions, not toward the products that convert best. Amazon's algorithm doesn't optimize for your account's profitability. It optimizes for its own click revenue.

Manual allocation forces the account to spend where the returns actually are. That's the whole game.

What good allocation looks like

Split your catalog into the three tiers above. Then allocate budget accordingly:

Sixty percent of ad spend goes to your high-converters. Push these hard. They're your account's engine.

Thirty percent goes to your average performers, but paired with a listing improvement plan. Every campaign here should have a defined listing project running alongside it. If the listing improvements aren't happening, cap the spend.

Ten percent goes to your low-converters, mostly for exposure and diagnostics. You want to know if any of them respond to specific traffic. But this isn't where your account grows.

The exact percentages depend on your catalog, but the shape holds across almost every account.

What to do this week

Pull your ASIN-level conversion report for the past 90 days. Sort by conversion rate. Identify your top three converters and your bottom three. Ask yourself: is your ad budget currently weighted toward the top or toward the bottom? If it's toward the bottom, you have a reallocation to run.
