Retail media has become one of the fastest-growing segments of digital advertising, and Amazon sits at its center. eMarketer's US Retail Media Ad Spending Report 2026 projects Amazon's retail media revenue will surpass $60 billion annually by the end of 2026, with third-party advertising agencies managing an increasing share of that spend on behalf of brands and manufacturers. Agencies operating in this space — managing Sponsored Products, Sponsored Brands, Sponsored Display, and Amazon DSP programs across ten, twenty, or fifty brand accounts simultaneously — face an acute reporting and audit burden that their account managers cannot absorb alongside active campaign management.
Virtual assistants trained in Amazon Advertising and retail media operations are resolving this bottleneck, handling the audit reporting and client-facing performance documentation that agencies need to deliver consistently without pulling account managers off optimization work.
The Reporting Complexity of Multi-Client Marketplace Advertising
Amazon Advertising's campaign structure — campaigns, ad groups, targeting types, match types, bidding strategies, placement modifiers — generates enormous reporting data even for a single brand account. An agency managing 25 brand accounts across Amazon Seller Central, Vendor Central, and DSP must process performance data across thousands of active campaigns on a weekly basis, identifying ACoS (Advertising Cost of Sale) trends, budget pacing anomalies, search term performance patterns, and competitor share of voice shifts.
According to Jungle Scout's State of the Amazon Seller Report 2025, 67% of Amazon sellers cite advertising management complexity as the top operational challenge in their marketplace business. For agencies, that complexity multiplies with each client added, and the reporting layer alone — pulling data, normalizing it, and producing client-ready summaries — can consume 2–3 hours per client account per week.
What an Amazon Advertising Operations VA Handles
Weekly Campaign Performance Pulls and ACoS Reporting The VA runs weekly performance exports from Amazon Advertising Console and DSP for each client account, compiling spend, impressions, clicks, conversion rates, and ACoS into a standardized per-client dashboard. Accounts where ACoS has moved outside agreed target ranges are flagged with trend annotations for account manager review. This creates a structured visibility layer that account managers can review in minutes rather than hours.
Campaign Structure Audit Reporting A common source of performance degradation in Amazon Advertising accounts is campaign structure drift — duplicate keywords across campaigns, poorly segmented ad groups, legacy campaigns with outdated bidding strategies, and orphaned auto-targeting campaigns draining budget without review. The VA conducts monthly campaign structure audits using a defined checklist, documenting findings in a structured audit report that account managers use to prioritize optimization tasks. Pacvue's Amazon Advertising Benchmark Report 2025 found that structured monthly audits reduce wasted spend by an average of 18% in mature accounts.
Search Term Report Analysis and Negative Keyword Administration Amazon's Search Term Reports are among the most data-dense outputs in the platform, requiring regular review to identify converting search terms for positive targeting and wasteful queries for negative keyword addition. The VA processes search term reports on a defined weekly schedule, flagging high-spend, zero-conversion queries for negative keyword consideration and identifying unmatched converting terms for positive campaign targeting — with all recommendations documented for account manager approval before implementation.
DSP Audience and Placement Reporting For agencies running Amazon DSP programs, the VA pulls audience performance reports, frequency data, and placement-level performance breakdowns, organizing findings into a DSP performance summary that maps spend against view-through attribution and direct sales metrics. This reporting layer is frequently under-resourced in agencies transitioning from self-serve Sponsored Ads to DSP management.
Client-Facing Performance Report Preparation Monthly client performance reports are one of the most time-intensive recurring tasks in marketplace advertising agency operations. The VA assembles report components from the weekly data library, populates a standardized template with period-over-period performance comparisons, campaign highlight summaries, and budget utilization data, and routes completed reports to the account manager for narrative addition before distribution. Agencies using this model consistently report that account managers spend 70% less time on report preparation.
Budget Pacing Monitoring Daily budget pacing checks ensure that client accounts are not over- or under-spending against monthly targets — a common problem in campaigns using Amazon's dynamic budget allocation features. The VA tracks actual spend against projected daily pacing, flagging material deviations to account managers for budget adjustment decisions.
Why This Model Scales
The economics of marketplace advertising agency operations favor a clear division between optimization work (account manager-owned, high-judgment) and reporting and audit work (VA-owned, process-driven). As eMarketer projects retail media spend to grow 22% year-over-year through 2027, agencies that build scalable reporting operations can grow their client base without proportional headcount expansion.
A VA managing reporting and audit operations for five to eight Amazon advertising accounts frees account managers to focus entirely on bid strategy, targeting expansion, and client strategic advisory — the functions that drive retention and justify premium management fees.
