Internal audit across 11 global marketplaces finds one-third of Amazon advertising budgets spent on keywords that never produce a sale.
SHERIDAN, WY, UNITED STATES, August 24, 2026 /EINPresswire.com/ — An internal audit by Sellers Umbrella Inc, an Official Amazon SPN Partner and Amazon Ads Verified Partner, found that 34% of ad spend across audited accounts went to keywords that produced no sales between January and May 2026. The finding spans accounts across 11 global marketplaces.
The pattern was consistent regardless of category or budget size. Campaigns were left on automated defaults set at launch and never revisited. Automatic campaigns ran for months without their winning search terms being harvested into manual campaigns, so the account kept paying discovery prices for terms that had already proven themselves. Broad match keywords quietly expanded into irrelevant queries. Negative keyword lists, where they existed at all, had stopped growing months earlier. And search term reports, the single document that exposes all of this, were being reviewed rarely or never.
The waste compounds quietly because the account still generates sales, so nothing looks broken. Revenue holds, ACOS creeps, and the seller attributes the drift to rising competition rather than to spend that was never supposed to be there. In many of the audited accounts, the seller had responded to worsening efficiency by raising budgets, which fed more spend into the same leaking structure.
The problem is sharper in 2026 than it was even two years ago. Advertising costs on the platform continue to climb as more brands compete for the same placements, and Amazon’s own campaign recommendations are built to expand reach, not to protect margin. A seller who accepts every suggested keyword, every suggested bid increase, and every suggested budget raise is following a roadmap written by the party being paid for the clicks.
Sellers can check their own exposure in minutes. Pull the search term report for the last 60 days, sort by spend, and count how many terms with meaningful spend show zero orders. Then check the date the negative keyword list was last updated. Accounts in the audit that had gone more than a quarter without this review showed the heaviest waste. Sellers operating in more than one marketplace should run the same check per country, because the audit found waste concentrated in secondary marketplaces where campaigns had been duplicated from the home market and left unattended.
The agency’s Amazon PPC management practice addresses this with a weekly operating cadence rather than a one-time cleanup: structured search term audits, negative keyword protocols that grow with the account, harvest routines that move proven terms from automatic to manual campaigns, and bid adjustments tied to conversion data rather than platform recommendations. Reporting follows the same discipline. Clients see what was spent, what converted, what was cut, and why, in plain terms, every reporting cycle.
“Most sellers are not overspending because they are careless,” said Nirav Bhatt, Founder of Sellers Umbrella Inc. “They are overspending because the platform is built to spend. Someone has to sit between the algorithm and the budget, and that someone needs to check the search term report every week, not every quarter.”
Bhatt noted the finding is not an argument against advertising on Amazon. “Advertising is how you buy visibility in a marketplace this crowded, and the sellers who advertise well are pulling further ahead every quarter. The finding is about the difference between spending and managing. The budget that goes to keywords that never convert is budget that should have been reallocated to the keywords that do.”
The finding also carries a message for brands already working with an agency or freelancer. The audited accounts were not all self-managed. A portion were under third-party management at the time of the audit, and the waste pattern was the same wherever the search term report was not part of a weekly routine. The question a brand should ask its current manager is not what the ACOS is, but when the search term report was last pulled and what was negated as a result.
The full methodology behind the finding is covered in the agency’s published guide, how we manage Amazon ad spend, written for sellers running their own campaigns and for teams deciding whether their current management is earning its keep.
