Campaigns getting no impressions
The three usual reasons an engine campaign is not being shown — no Buy Box, an ineligible or out-of-stock product, or a target so tight the engine bids too low — and how to check each one.
TL;DR: No impressions almost always means one of three things: you do not hold the Buy Box on that product, the product is not eligible to advertise (out of stock, suppressed, or against policy), or your ACoS target is so tight that the engine's bids are losing every auction. Ask the agent which it is.
Impressions are the first thing to go missing and the last thing worth panicking about. Work through these in order; the agent can check the first two for you — "why is B07ABC1234 getting no impressions?"
1. You do not hold the Buy Box
Amazon only shows Sponsored Products ads for an offer that is winning the Buy Box. If another seller — or Amazon itself — holds it on that ASIN, your ads are eligible but never served, however high the bid. Check the listing on Amazon: if "Sold by" is not you, that is the reason. Price, stock and fulfilment are the usual levers.
2. The product is not eligible to advertise
- Out of stock or nearly. The engine pulls bids back when fulfillable stock is low, deliberately — see Your products in Autron.
- Suppressed or ineligible listing. A listing with missing images, a policy issue or a category restriction cannot be advertised. Amazon shows the eligibility status against each ad in the campaign manager.
- Brand-new listing. A product with no sales history and few reviews wins fewer auctions and converts less; the engine bids accordingly and ramps as data arrives.
3. Your target is too tight
If the Buy Box and eligibility check out, look at the target. The engine bids to keep your actual ACoS under the cap you set. A cap far below what the product has historically run — or below its break-even — leaves the engine bidding too little to win auctions, and the row's Status on Goals reads Conflicts with goal. Raise the cap toward your current ACoS and walk it down over the following weeks. See Manage goals.
Still nothing after two days
Ask the agent what the engine has done on the product — "what has the engine changed on B07ABC1234 this week?" — and, if it reports nothing at all, email hello@autron.ai with the ASIN.
