Amazon Ads Auction Surcharges: What The FTC Allegations Mean For PPC, Profit, And Trust (And How To Future‑Proof Your Measurement)
Newly unredacted FTC allegations say Amazon quietly raised effective CPCs—especially during Prime Day and Black Friday—by applying undisclosed auction surcharges. Here’s what changed, why it matters for brands and agencies, and the practical steps to audit past performance, rebuild benchmarks, and protect future event budgets with better measurement and approved execution.
By Marius Dosinescu (AYSA.ai)
Advertising is built on a simple trade: you pay for reach and demand, and the platform gives you a market-based price signal you can use to make rational decisions. When that price signal is distorted—especially in ways advertisers can’t observe—every downstream decision gets riskier: budgets, forecasts, inventory buys, margin targets, and even how you judge your marketing team.
That’s why the newly unredacted allegations in the Federal Trade Commission (FTC) and state attorneys general complaint against Amazon matter far beyond one platform. The complaint, as reported by Search Engine Journal, alleges Amazon applied undisclosed auction “surcharges” that raised cost-per-click (CPC) above what the auction would otherwise produce—up to 50% on ordinary days and up to 250% during major shopping events like Prime Day and Black Friday (per the complaint’s allegations, still being litigated).1
This isn’t a how-to guide for blaming a platform. It’s an operational guide for protecting your business when a core input (auction pricing) may be less transparent than you assumed. If you run ecommerce, manage marketplace spend, or lead an agency responsible for results, you need a plan to: (1) audit the past without rewriting history, (2) rebuild benchmarks that won’t sabotage future budgets, and (3) tighten the measurement and governance loop so you’re not flying blind the next time CPCs spike.
AYSA.ai’s perspective is simple: measurement without execution is theater, and execution without measurement is gambling. Our job is to help you monitor, prepare changes, ask for approval, and execute accepted improvements on your website—so your marketing performance depends less on platform mysteries and more on assets you control.
Concise summary

- The FTC’s newly unredacted complaint (as summarized by Search Engine Journal) alleges Amazon used undisclosed auction mechanisms (“soft reserve” pricing) that increased advertisers’ effective CPCs—especially during Prime Day and holiday peaks.1
- Even if you “never pay more than your max bid,” your actual CPC can still be elevated relative to what competitive bids would imply—changing ROAS, forecast accuracy, and your view of channel efficiency.
- Your 2021–2023 event benchmarks may be contaminated. If you use those windows to set 2026–2027 targets, you may be budgeting against a distorted baseline.
- The fix is not one metric. It’s a system: triangulate auction outcomes with business outcomes, create event-specific baselines, annotate platform changes, and build alerting for CPC/CR divergence.
- AYSA fits by tightening the “owned-asset” side: faster landing page improvements, better SEO/AEO/GEO coverage, clearer messaging, and Approved Execution so you convert more of the traffic you pay for.

What changed: the unsealed allegations, in plain English

Search Engine Journal reports that the FTC and 22 state attorneys general filed an updated complaint with newly unredacted sections describing how Amazon allegedly inflated prices in its online search advertising auction.1 The unsealed details include specific examples from 2021–2023, including shopping events, internal revenue discussions, and advertiser questions about CPC spikes.
Here are the key allegations as described in the report (not proven facts; they’re claims in ongoing litigation):
- Hidden CPC increases above “auction results.” The complaint allegedly describes increases up to ~50% above auction outcomes on typical days and up to ~250% during major shopping events (Prime Day and Black Friday).1
- Event-specific impacts. Examples cited include: during the 2021 holiday season, average CPC increases; in 2022, a target tied to additional worldwide revenue; and during Prime Day 2023, internal acknowledgments that the increases harmed ROAS and “destroyed campaign performance” for at least one large advertiser (as quoted in the complaint summary).1
- Use of “soft reserve prices.” The complaint centers on Amazon’s alleged use of reserve pricing in ways advertisers weren’t clearly told about, and that were described to advertisers using language that could be misleading about how auctions were priced.1
- How Amazon responded when questioned. The unredacted sections reportedly include an advertiser asking whether the second-price auction process changed; the complaint alleges an Amazon account manager attributed higher CPCs to a crowded marketplace rather than any auction change.1
- Amazon’s defense (as previously stated). Search Engine Journal notes Amazon denied deceiving or harming advertisers and maintained advertisers never pay more than their maximum bid.1
On its own, each of these points might sound like an inside-baseball dispute about auction mechanics. In practice, it touches every serious advertiser’s operating model: forecasting, efficiency targets, incrementality, and how you justify budgets to a CFO.
Why it matters: PPC isn’t just a cost center—it’s a price signal
Most teams treat CPC as “the cost of doing business.” But in a well-behaved auction, CPC is more than a bill—it’s a price signal about market demand and competitive pressure. That signal informs decisions like:
- How aggressively to fund Prime Day vs. hold budget for Q4
- Whether the problem is creative, product-market fit, or bidding
- How much margin to allocate to customer acquisition
- Whether to expand into new keywords or placements
- How to value top-of-funnel vs. branded defense
If the price you paid isn’t closely tied to competitive bids (or isn’t transparently explained), that “signal” becomes noisy. And noisy signals cause predictable failure modes:
- False negatives: you conclude a product can’t scale profitably, when the issue is cost distortion.
- False positives: you attribute wins to strategy, when the real driver was a temporary pricing artifact or reporting change.
- Benchmark drift: you lock in bad baselines that infect next year’s planning.
That’s why these allegations—again, still allegations—matter to every business running marketplace ads. Not because your account is guaranteed to have been affected, but because the possibility forces a different posture: less blind trust, more independent Monitoring, better documentation, and more leverage built outside any one auction.
The Most Important Takeaway: Your “Event Benchmarks” May Be Contaminated
If you only implement one idea from this editorial, make it this:
Stop treating 2021–2023 peak-event performance as a clean baseline.
Many brands plan like this:
- Look at Prime Day last year → set a ROAS target for this year
- Use last year’s CPCs → project Clicks and revenue for a budget request
- Compare year-over-year → judge team performance
If the complaint’s allegations are accurate, then event-period CPCs in those years may include an uplift that your models interpret as “normal auction pressure.” That has three downstream consequences:
1) You may be underfunding future events
If you expect CPC to be “naturally” sky-high, you may reduce budgets early, miss impression share, and lose out on what could actually be efficient demand—especially if platform dynamics shift again.
2) You may be over-crediting optimization decisions
If CPC later declines (for any reason), you might attribute it to bid tactics or creative improvements that weren’t the real cause. That’s dangerous because it teaches the wrong lessons.
3) You may be misjudging channel mix
Teams often compare Amazon Ads vs. Google Ads vs. paid social by looking at blended ROAS. If one channel’s auction pricing had hidden uplifts, you may have shifted spend away from it—and that might have been correct or incorrect. The point is: your decision was made on compromised comparability.
So what do you do? You don’t erase history—you re-annotate it. You treat those periods as “high uncertainty” and you run planning models with ranges, not single-point forecasts. Later in this article, I’ll outline an audit workflow that’s practical even if you’re a small team.
A Practical Explainer: How An Ad Auction Can Raise Your CPC Without Raising Your Bid
To understand why the allegations are such a big deal, you need one clear concept: your bid is a cap; your CPC is the clearing price.
Platforms commonly describe search auctions using simplified stories—often some variant of a “second-price” auction narrative. The basic intuition: you pay roughly what the next competitor was willing to pay (plus small adjustments), not necessarily your full max bid.
In the real world, auction pricing can include additional mechanisms. One of them, as referenced in the complaint summary, is reserve pricing, including what Amazon reportedly calls a “soft reserve.”1
Reserve pricing, in business terms
A reserve price is essentially a threshold the platform wants to achieve for a placement. Some reserves are explicit (like a minimum bid to participate). Others can be implicit (a target price the platform tries to clear, but may still allow exceptions).
In practice, a reserve can raise what you pay in at least two ways:
- It can lift the clearing price even when the next bid would have produced a lower CPC.
- It can change who wins and at what price, making your performance less predictable relative to competition.
Now, it’s important to be precise: the complaint summary (via Search Engine Journal) also notes Amazon’s defense that advertisers never pay more than their max bid.1 Both things can be true at the same time:
- You never pay above your max bid.
- You pay more than you otherwise would have in a transparent auction priced strictly by competing bids.
For advertisers, that distinction matters because most models assume the clearing price is primarily driven by competitors (and your quality / relevance, where applicable), not by an internal revenue target or an undisclosed reserve mechanism.
Why disclosure matters more than mechanics
Reserve pricing itself isn’t inherently “illegal” or “unethical” in every context. Marketplaces have legitimate reasons to manage quality, discourage spam, and ensure ad load doesn’t degrade the shopping experience.
The problem—if the allegations are true—is about transparency and expectation-setting:
- If a platform explains auctions in a way that implies one pricing model, while it routinely charges in another way, advertisers cannot make informed choices.
- If advertisers ask directly “did the auction change?” and they’re told “no,” while internal mechanisms changed, that’s a trust fracture—because it breaks the feedback loop required to optimize.
Optimization depends on truth. Not philosophical truth—operational truth.
The Measurement Problem: Campaign Reports Tell You What You Paid—Not Why You Paid It
Even highly sophisticated brands often overestimate what their ad platform reporting can answer. Most platform UI and exports are designed to answer questions like:
- What did I spend?
- What clicks and sales did I get?
- Which keywords or products “performed”?
They are not designed to answer:
- What was the auction clearing price absent internal reserves?
- How much of my CPC change was due to competition vs. platform pricing rules?
- Did a platform adjust pricing logic during this event window?
This is the core operational challenge raised by the complaint summary: advertisers can see CPC spikes, but they can’t easily diagnose the cause. Search Engine Journal reports that advertisers asked Amazon whether something changed with the auction process; the complaint alleges they were told it was simply a more crowded marketplace.1
That’s why an “audit” cannot rely solely on platform dashboards. You have to triangulate from multiple angles:
- Business outcomes: margin, inventory, refunds, repeat purchase behavior.
- Site experience: landing Page speed, stock availability, pricing changes.
- Channel comparisons: did other auctions spike similarly at the same time?
- Placement mix: were you pushed into more expensive placements?
- Operational timeline: what else changed that week (creative, feed, promos)?
None of this proves or disproves any allegation. But it does help you make better decisions under uncertainty—which is what business is, most days.
Why Peak Events Are Uniquely Vulnerable To Auction Distortions
The unsealed allegations emphasize shopping events because that’s where distortion has the biggest impact. Whether you’re on Amazon, Google, or any retail media network, event periods share four characteristics:
1) Demand is inelastic in the short window
During Prime Day or Black Friday week, you can’t “make up” for missing demand later. If you go dark or lose impression share, the opportunity is gone.
2) Competitive pressure spikes simultaneously
Brands synchronize promos and budgets. CPCs naturally rise—making it harder to distinguish “normal” competition from structural pricing changes.
3) Leadership attention is highest
When CEOs and CFOs are watching, every performance dip becomes a crisis—and the marketing team’s credibility is on the line.
4) Your measurement errors compound
At high spend levels, small deviations matter. A 10% pricing shift can decide whether an event was profitable, break-even, or a loss leader you can’t afford.
That’s why “wait and see” is not a strategy. You need event governance: defined guardrails, alerting, and post-mortems that are honest about what you can and can’t know from the data you have.
A Concrete SME Scenario: The $60 AOV Brand That “Lost Prime Day”
Let’s make this real with a scenario that mirrors what many small and mid-sized ecommerce companies experience.
Business: A direct-to-consumer kitchen accessories brand selling on Amazon and its own Shopify site. Average order value (AOV) is around $60. Gross margin after cost of goods and shipping is tight, so the company needs efficient acquisition during event windows.
Prime Day plan:
- Increase Sponsored Products budgets
- Run a 20% discount
- Hold ROAS target steady based on last year’s event results
What happens:
- CPC rises sharply within hours
- ROAS falls
- Sales volume rises, but profit drops
- The team “fixes” it by lowering bids and tightening targets
What they conclude (often incorrectly): “Competition is crazy; Prime Day is no longer profitable for us.”
What could also be true:
- Competition increased and the platform’s effective pricing rules shifted.
- Or competition increased but the real issue was their landing page (on their own site) was slow, inventory was constrained, or their promo messaging didn’t match shopper intent.
The point of the FTC allegations isn’t that every CPC spike is a hidden surcharge. It’s that you need a process that can survive uncertainty.
This is where many SMEs get stuck: they only have one lever (bids), one view (platform UI), and one outcome metric (ROAS). That’s a fragile operating model.
A more resilient model is to diversify levers:
- Paid media controls (bids, budgets, placements)
- Merchandising (price, promo depth, bundles)
- Owned asset improvements (site speed, messaging, FAQs, comparison pages)
- Search visibility outside marketplaces (SEO + AI Search visibility)
That last category—owned assets—is where AYSA provides compounding value, because improving conversion and clarity reduces your dependence on perfect auction conditions.
What Agencies Should Rethink: Contracts, Comms, And Guardrails
If you’re an agency, these allegations (and any similar platform controversy) create a specific risk: you can be blamed for variables you cannot control. That doesn’t mean you shrug. It means you upgrade the way you manage expectations and document decisions.
1) Redefine “optimization” as a documented process, not just outcomes
When CPC spikes, clients ask: “What did you change?” Sometimes the answer is: “Nothing changed—market conditions did.” But you need a paper trail to prove you were monitoring and responding within agreed guardrails.
Consider adding to your SOW:
- Event-specific governance: budget caps, bid caps, dayparting rules
- Alerting responsibilities and response times
- Post-event audit deliverables (what changed, what we know, what we don’t)
2) Use ranges, not single-point targets, for peak events
Events are volatile. If your forecast assumes a single CPC and a single CVR, you are asking for conflict later. Provide scenarios (best/base/worst) and explain which levers move each scenario.
3) Separate “platform efficiency” from “business efficiency”
Platform ROAS can diverge from actual profitability if returns, discounts, or attribution shifts. Peak events amplify that divergence. Agencies that build trust are the ones that speak CFO language: contribution margin, cash flow, and inventory risk.
4) Coordinate owned-asset improvements faster
Agencies often find the real bottleneck isn’t ad settings—it’s the website, product pages, or content needed to convert. If you need three weeks of internal approvals to change a landing page, you are structurally disadvantaged during event windows.
This is exactly why we designed AYSA around approved execution: monitoring and recommendations are worthless if they never ship.
The Action Plan: How To Audit 2021–2023 Performance Without Guessing
Search Engine Journal’s article suggests advertisers revisit 2021–2023 event benchmarks and brief stakeholders with the unsealed context.1 That’s right, but it’s not enough. You need an audit method that produces decisions, not just insights.
Here’s a practical audit workflow you can run in a week (small team) or two (larger org), without needing secret data from any platform.
Step 1: Build an “event timeline” with annotations
Create a simple document (Google Doc or Notion) for each major event window (Prime Day, Black Friday week, Cyber Monday). Include:
- Exact dates and hours of the event
- Your budget changes (daily caps, pacing rules)
- Bid strategy changes
- Creative changes
- Pricing changes and promo depth
- Inventory status and stockouts
- Operational incidents (site downtime, feed errors)
Goal: Don’t start with metrics. Start with what changed. Metrics without a change log are just vibes.
Step 2: Split the window into pre-event, event, and post-event cohorts
Don’t evaluate “Prime Day week” as one blob. You want at least:
- 7–14 days pre-event (baseline)
- Event days/hours (shock period)
- 3–7 days post-event (hangover/attribution lag)
Goal: Identify whether CPC rose only during event hours (more consistent with event dynamics) or also before/after (suggesting structural changes, competition ramp, or other factors).
Step 3: Plot CPC against conversion rate (CVR) and impression share proxies
You’re looking for patterns like:
- CPC up, CVR flat/down: cost pressure is the likely culprit; investigate auction and placement mix.
- CPC flat, CVR down: your offer, inventory, or page experience may be the issue.
- CPC up, CVR up: you may still be okay—profit depends on margin and AOV, not ROAS alone.
If your platform provides impression share, top-of-search share, or placement breakdowns, include them. If not, use what you can (e.g., ranking/visibility proxies, or changes in clicks at a constant budget).
Step 4: Recompute “event ROAS” as a margin-based metric
ROAS is not profit. Rebuild your event performance using:
- Contribution margin per order (after discounts)
- Returns/refunds (if you have them)
- Incremental cost to fulfill (overtime, expedited shipping)
Goal: Decide whether the event is a profit engine, a break-even customer acquisition play, or a loss you should cap.
Step 5: Create a “clean benchmark” range for future planning
Instead of saying “Prime Day CPC is $X,” define a range:
- Expected CPC range
- Expected CVR range
- Expected blended margin range
Then define triggers:
- If CPC exceeds the upper bound and CVR doesn’t increase, reduce bids or shift budget to higher-intent targets.
- If CVR collapses, check inventory and promo alignment before you touch bids.
Step 6: Write the stakeholder briefing (one page)
Search Engine Journal recommends briefing clients/internal stakeholders using the unsealed context.1 Do it in a disciplined format:
- What happened: CPC changed by X% during Y window
- What we controlled: bids/budgets/creative
- What we did not control: auction pricing mechanisms, competition
- What we know: observed metrics
- What we don’t know: platform internal pricing logic
- What we will do next: guardrails + monitoring + owned-asset improvements
This creates trust because it’s honest. It also reduces the chance that your team gets punished for an unknowable variable.
The Monitoring Playbook For Upcoming Events: What To Watch Weekly And Hourly
When you approach an event like Black Friday/Cyber Monday, you don’t want to “analyze later.” You want to detect early.
Here’s a monitoring playbook you can use regardless of platform. It’s intentionally platform-agnostic because the underlying risks are universal.
Weekly (4–6 weeks out): readiness indicators
- Offer readiness: Is your promo plan final? Are bundles and pricing locked?
- Inventory risk: What SKUs might stock out? Do you have substitutes?
- Landing page clarity: Are the top 10 paid landing pages aligned to event intent?
- Conversion hygiene: Checkout friction, page speed, mobile usability
- Measurement hygiene: Can you reconcile platform revenue with internal orders?
Daily (7 days out): divergence detection
- CPC trend: is it rising ahead of the event unusually fast?
- CVR trend: is it stable or falling?
- Placement/format mix: are you buying the same type of traffic as last week?
- Search term/product targeting drift: are you expanding into lower-intent queries due to budget pressure?
Hourly (event days): guardrails and triage
- Pacing vs. performance: are you burning budget early at poor efficiency?
- CPC vs. CVR divergence: CPC up but CVR flat/down is a red flag.
- Stockouts: pause ads to OOS SKUs immediately.
- Offer mismatch: if promos aren’t reflected clearly, fix messaging fast.
Notice what’s missing: “blame the platform.” Monitoring is about response capability.
The Strategic Pivot: Build Leverage Outside The Auction
Even if every platform auction were perfectly transparent, relying on auctions alone is a fragile strategy because you don’t own the rules. The best brands use paid media as an accelerator—not as the foundation.
To reduce dependency on auction conditions, invest in three leverage areas:
1) Improve conversion rate (so CPC matters less)
If you convert 20–30% better than you did last year, a CPC spike hurts less. Conversion improvements come from:
- Clearer value propositions
- Better product detail pages and FAQs
- Trust signals: shipping, returns, reviews
- Faster performance (mobile especially)
These are owned-asset improvements. They compound.
2) Expand non-auction demand capture (SEO/AEO/GEO)
When shoppers research in search engines and AI assistants, visibility isn’t only “rank #1” anymore. It’s also “are you cited, summarized, and recommended?” That’s the world of AI Search visibility and AEO/GEO.
Whether you’re selling products or services, your site needs to answer questions in formats machines can reliably interpret: comparisons, specs, policies, and decision guides.
AYSA resources if you want to go deeper:
3) Build operational speed (approved execution)
Most businesses don’t lose because they lack ideas. They lose because they ship too slowly.
If CPC spikes mid-event, you may need to:
- Update landing page messaging
- Add an FAQ block addressing objections
- Create a comparison page to reduce price sensitivity
- Fix a broken tracking parameter or canonical issue
Execution speed is a competitive advantage. This is the core design philosophy behind AYSA: monitor → prepare → ask for approval → execute on your website changes in a governed way.

Where AYSA Fits: Approved Execution For SEO/AEO/GEO That Improves Paid Efficiency
Let’s be explicit: AYSA isn’t an ad auction. We don’t set Amazon’s CPCs. We don’t “hack” platform pricing. That’s not the point.
AYSA is an execution system for the assets you do control—your website and your search visibility—so that paid traffic performs better and your growth plan is less dependent on any single marketplace’s auction rules.
1) Monitoring that connects search visibility and business outcomes
When your CPC rises, one of the few ways to keep profitability stable is to convert more of the click. AYSA helps you identify and prioritize site changes that improve conversion and clarity.
Start here: Monitoring
2) SEO/AEO improvements that reduce reliance on paid media
If your only growth lever is paid spend, you’re exposed to auction volatility. Building durable demand capture via SEO and AI search visibility gives you a second engine.
Explore:
3) Approved execution: ship changes without chaos
Many AI tools stop at “recommendations.” That’s where businesses stall. AYSA prepares changes and asks for your approval before executing—so teams can move faster without letting an agent freely edit production pages.
For teams who need governance, this model is the difference between theory and results.
4) Budget justification and cross-channel credibility
In an environment where auction pricing can be questioned, credibility comes from how you document and operationalize decisions.
AYSA helps teams maintain a clear record of what changed on the website, when it changed, and why—so when performance shifts, you can separate “we improved conversion” from “auction costs rose.” That’s how you talk to finance with confidence.

What To Do Next (Action List)
Here’s a practical next-step checklist you can run this month—even if you’re a small team.
- Pull your 2021–2023 event windows (Prime Day + Black Friday/Cyber Monday) and tag them as “high-uncertainty baselines” in your reporting.
- Create a one-page event change log for each window: budgets, bids, promos, inventory, creative, site changes.
- Rebuild benchmarks using ranges (CPC, CVR, margin), not single numbers.
- Add divergence alerts: CPC up + CVR flat/down; budget burn anomalies; stockout detection.
- Update stakeholder comms: explain what you can know from reports vs. what is inherently opaque.
- Invest in owned-asset conversion improvements before the next event: top landing pages, FAQs, shipping/returns clarity.
- Build a second engine: SEO + AI search visibility, so performance isn’t hostage to a single auction.
- Implement governed execution so improvements actually ship; explore AYSA’s workflow via AYSA Blog and Monitoring.
