Responding to unfair ranking complaint under EU rules the right way

TL;DRAn unfair ranking complaint under EU rules on Amazon Italy is a formal challenge to how a platform orders, demotes, or suppresses a seller's listings – and under the Platform-to-Business (P2B) Regulation, sellers have specific procedural rights that Amazon must respect. The P2B Regulation requires Amazon to set out its main ranking parameters in its terms and to give sellers a statement of reasons when those terms change in ways that affect them. The realistic path runs from internal complaint through the platform's own system, then to mediation if that fails, and in some matters to regulatory escalation or litigation. Getting the sequence right from the first filing is what determines whether later options remain open.

Here is what this guide covers: what an unfair ranking complaint actually is on Amazon IT under current EU rules, the step-by-step procedural path, where sellers most often go wrong, the decision points you will face, and how to assess whether professional help is the right call for your situation.

What is an unfair ranking complaint under EU rules on Amazon IT?

A ranking complaint under EU law is not a generic grievance about visibility. It is a specific legal claim that Amazon has applied its ranking criteria in a way that is inconsistent with its own disclosed terms, or that it has changed those criteria without adequate notice or explanation.

The Platform-to-Business Regulation (EU) 2019/1150 – known as the P2B Regulation – sets the legal floor. It requires intermediation services like Amazon to describe the main parameters determining ranking in their terms, and to set out the relative importance of those parameters. Where Amazon privileges its own retail offers or those of sellers who use its fulfilment and advertising services, the P2B Regulation requires that differential treatment to be disclosed.

The Digital Services Act (DSA) adds a further layer. Amazon operates as a Very Large Online Platform (VLOP) under the DSA, meaning it faces enhanced obligations around transparency, systemic risk, and the handling of complaints from business users. When a seller's listing is suppressed or demoted, the DSA's statement-of-reasons requirement means Amazon should explain the decision in terms the seller can actually act on.

On Amazon IT specifically, the Italian market carries its own enforcement context. The Autorità Garante della Concorrenza e del Mercato (AGCM) has previously reviewed Amazon's practices under Italian competition law, and P2B enforcement sits within an EU-wide framework that gives sellers a recognized internal complaint path before any external route is considered. In matters we handle involving Amazon IT, the starting point is always identifying which specific rule – P2B disclosure, DSA statement of reasons, or a potential self-preferencing issue under the Digital Markets Act (DMA) – gives the complaint its legal grounding.

A ranking complaint also needs to be distinguished from a listing removal or account suspension. Those have their own procedural paths. An unfair ranking complaint targets the demotion or suppression of a listing that remains live but has lost placement – often without any explicit notice to the seller, which is itself part of the legal problem.

What are the EU rules that protect sellers on Amazon IT from unfair ranking?

Three intersecting instruments define the seller's legal position. Understanding each one matters because they produce different remedies and different escalation routes.

The P2B Regulation is the most directly applicable. It applies to all online intermediation services operating in the EU – regardless of where the platform is established – and it grants business users enforceable rights. The key ones for a ranking complaint are: the right to clear terms describing ranking parameters; the right to at least 15 days' advance notice of changes to those terms that are not required by law; and the right to use an internal complaint-handling system that the platform must maintain and operate effectively. The 15-day advance notice rule applies to changes in general conditions; emergency changes required by law or addressing a sudden platform risk may be implemented immediately, but the seller must still be informed.

The DSA added transparency requirements around recommender systems and algorithmic decisions. For a VLOP like Amazon, those requirements are more demanding than for smaller platforms. When a seller's listing is algorithmically demoted, the DSA framework supports a claim that Amazon should explain the ranking logic applied – not just point to generic help-center text.

The DMA is relevant where the ranking complaint involves self-preferencing: Amazon pushing its own products or services ahead of independent sellers in a way that the DMA prohibits for designated gatekeepers. Amazon has been designated a DMA gatekeeper for several of its core platform services. A self-preferencing dimension to a ranking complaint can lift the matter from a bilateral P2B dispute into the territory of DMA enforcement – which operates through the European Commission rather than through Amazon's internal system. Our guide on self-preferencing complaints under the DMA covers that route in detail; this guide focuses on the P2B/DSA path for ranking suppression that does not necessarily involve a gatekeeper obligation.

Italian law also plays a role. Amazon IT operates under Italian contract law, and the AGCM can investigate unfair commercial practices by platforms. A ranking complaint that exhausts the platform's internal system without resolution can, in the right circumstances, support a complaint to the AGCM or provide the factual basis for civil proceedings in Italy.

How does the step-by-step process actually work for an unfair ranking complaint on Amazon IT?

Every effective ranking complaint under EU rules follows a documented sequence. The sequence matters because later options – mediation, regulatory escalation, litigation – depend on having completed earlier steps correctly.

Step 1: Identify and document the ranking change. Before filing anything, the seller needs to establish a factual baseline. That means capturing evidence of the demotion: search result positions across relevant Italian search terms, Buy Box suppression data, advertising performance curves, and sales velocity data showing when the change took effect. Screenshots with date-time stamps, exported reports from Seller Central, and any notifications received from Amazon form the evidentiary record. The absence of a notification is itself potentially significant under the DSA.

Step 2: Review Amazon's disclosed ranking terms. The P2B Regulation requires Amazon to publish its ranking parameters. The seller's complaint must be grounded in a specific mismatch between what Amazon disclosed and what it actually did – or in a failure to disclose at all. This step often reveals that Amazon's published criteria are broad enough to give it wide discretion, which shapes how the complaint must be framed. Vague published criteria can themselves be challenged under P2B if they fail to give the seller meaningful information.

Step 3: File through Amazon's internal complaint-handling system. The P2B Regulation requires Amazon to operate an internal complaint-handling system that is free of charge, easily accessible, and able to deliver outcomes within a reasonable timeframe. On Amazon IT, the path starts in Seller Central. The complaint must be specific: cite the P2B Regulation (and the DSA where the statement-of-reasons point applies), identify the exact listings affected, describe the observed demotion, and request a formal explanation of the ranking criteria applied to those listings. Generic appeals will be routed to standard customer service and will not engage the P2B complaint pathway. In matters we handle, a properly filed P2B complaint looks materially different from a standard Seller Central contact – it invokes the regulation by name and requests a compliant response.

Step 4: Wait for the platform's response and assess it. Amazon must respond. The P2B Regulation does not set a hard deadline in the sense of a single fixed number of days, but it does require the complaint-handling system to deliver results within a reasonable time. If the response is substantive, the seller must assess whether it actually addresses the legal points raised or merely restates platform policy. A response that fails to engage with the P2B ranking-parameter disclosure obligation is itself a procedural failure that strengthens the case for the next step.

Step 5: Escalate to mediation if the internal path fails. Where the internal complaint-handling system does not resolve the matter, the P2B Regulation gives sellers the right to use a mediator from a list that Amazon is required to maintain and to fund at least partly. Mediation under P2B is not arbitration – it is a facilitated process aimed at reaching agreement. The seller must have attempted the internal complaint system first; mediation is not a shortcut around it. Mediation is worth considering when the dispute involves a clear, documented breach of Amazon's own published terms and the financial impact justifies the time investment. It tends to be less useful when the ranking complaint is about broad algorithmic suppression without a specific, identifiable rule breach.

Step 6: Assess the external escalation options. If mediation fails or is not the right tool, the seller has several external routes. A complaint to the relevant national authority (the AGCM for Amazon IT) is one. A DSA complaint to the EU's Digital Services Coordinator is another where the transparency/statement-of-reasons dimension is strong. Where the DMA applies – because the complaint is really about self-preferencing – the path is to the European Commission's DMA enforcement team. Civil litigation in Italy is also available, particularly where the seller can quantify the commercial loss caused by the demotion. The choice among these routes involves trade-offs in time, cost, and the type of outcome available, which we cover in the decision-points section below.

For sellers also dealing with a platform suspension alongside the ranking issue, our analysis in German marketplace suspension and the seller's real options illustrates how the same P2B/DSA framework applies across Amazon's EU markets, with national-law variations.

Where do sellers most often go wrong with an unfair ranking complaint on Amazon IT?

A complaint that starts with the wrong framing rarely recovers. The most common mistakes are concrete and predictable.

Filing a standard appeal instead of a P2B complaint. The most frequent error we see is sellers contacting Amazon's seller support as they would for any account issue, without invoking the P2B Regulation. Amazon's internal system will route that contact through normal support channels, and the response – if any – will not engage with the platform's legal obligations. A response that merely restates platform terms and asks the seller to "review the listing quality guidelines" is not a P2B-compliant response. But if the seller never invoked P2B in the first place, there is no procedural record of a failure to respond under the Regulation.

Failing to preserve evidence before filing. Amazon's search results change continuously. A seller who notices a demotion and waits days or weeks before beginning to document it may find that the baseline is gone. Evidence of position data, Buy Box status, and advertising performance must be captured at the earliest opportunity – before any communication with Amazon, not after.

Conflating ranking suppression with listing removal. These are procedurally distinct. A removed listing has a specific reinstatement path through Seller Central's appeal process. A suppressed or demoted listing that remains live has no automatic appeal pathway, which is precisely why the P2B internal complaint system is the correct route. Sellers who try to use the reinstatement appeal process for a ranking issue will receive a response that misses the point.

Skipping the internal complaint step to go straight to a regulator. This is intuitive – regulators sound more powerful – but it is procedurally backward. P2B mediation requires prior use of the internal system. Regulatory bodies like the AGCM also look more favorably on complaints that have a documented trail of prior engagement with the platform. Jumping to a regulator without completing the internal path can weaken the complaint and delay any resolution.

Accepting a non-response as an answer. Amazon's internal system can issue what is in effect a non-response: a standard acknowledgment that does not address the specific legal points raised. Sellers who accept this and move on have forfeited the procedural record they need for the next step. The correct response to a non-compliant platform response is to document it and treat it as a trigger for escalation.

Our broader complete guide to EU marketplace regulation for sellers covers the P2B framework in full, including the rights that apply at each stage of the complaint process.

What are the seller's decision points and trade-offs?

After the internal complaint step, a seller on Amazon IT faces genuine choices – and the right choice depends on the specific facts of the ranking complaint, not on a generic preference for one route over another.

Internal complaint versus immediate escalation. The internal path is mandatory before mediation under P2B, so this is less a choice and more a sequence. But the seller does have discretion in how hard to push the internal path before treating it as exhausted. A well-structured internal complaint that invokes P2B specifically sometimes produces a substantive response from Amazon – particularly where the factual record is strong and the breach of the disclosed ranking terms is clear. In our experience, sellers who file a precise, regulation-invoking complaint at step one get a more useful response than those who use the generic Seller Central contact form.

Mediation versus regulatory complaint. Mediation under P2B can produce a binding outcome faster than a regulatory investigation, but only if both parties engage in good faith. A regulatory complaint to the AGCM or a DSA complaint to the Digital Services Coordinator may produce a systemic change in platform behavior, but the timeline for regulatory proceedings is typically much longer than mediation, and the outcome does not necessarily address the individual seller's specific loss. If restoring the listing's ranking position is the immediate goal, mediation is usually the faster path. If the complaint is part of a broader pattern affecting multiple sellers, a regulatory filing may have value beyond the individual case.

DMA escalation. Where the ranking complaint involves Amazon systematically preferring its own products – the self-preferencing prohibition under Article 6 of the DMA – the individual seller's complaint can be filed with the European Commission. This is not a quick remedy for a business whose Amazon IT sales are suppressed today. It is a structural enforcement route. The decision to pursue it alongside the P2B/DSA path depends on whether the seller has the documentation and the commercial staying power to participate in what may be a multi-year process.

Civil litigation in Italy. Where the seller has suffered a quantifiable loss – a documented revenue drop tied to the ranking change, with the evidentiary record to support it – Italian civil proceedings offer the possibility of damages. This route requires the most preparation, the strongest evidence, and the willingness to litigate against a well-resourced counterparty. It is rarely the first move, but it is a real option where the other routes have been exhausted or have produced inadequate outcomes.

The decision matrix, in brief: if the notice cites a specific policy breach in disclosed ranking terms and the loss is recent and documented, the internal P2B complaint followed by mediation is the right first path, on a timeline of weeks to a few months. If instead the suppression appears to be algorithmic without any specific rule breach Amazon has acknowledged, the route involves a stronger DSA statement-of-reasons demand and, if that fails, a regulatory complaint, on a longer timeline. If the issue is self-preferencing, the DMA path runs in parallel, as the guide referenced above explains.

A mid-sized home-goods seller on Amazon IT (winter 2026) came to us after its primary category listings lost significant placement across Italian search terms with no notice from Amazon and no explanation in Seller Central. We reviewed the account's P2B complaint history – there was none – drafted a regulation-invoking internal complaint with the full evidentiary record, and pushed for a specific statement of reasons under the DSA. Amazon's response was substantive, acknowledged a ranking system update, and partially restored the listings' prior positions within several weeks. The matter remained open for the balance of the position recovery, but the seller was able to resume normal operations during the process.

A second matter involved a software accessories distributor on Amazon IT (spring 2027) whose sponsored and organic positions had both declined after onboarding a third-party logistics provider, breaking reliance on Fulfillment by Amazon. We identified a documented disclosure issue – Amazon's ranking terms had not clearly disclosed the weighting given to fulfilment method – and filed an internal P2B complaint on that ground specifically. The outcome of that matter remains ongoing at the time this guide was published, but the P2B filing established the procedural record needed for the next steps.

How do I assess whether my ranking complaint qualifies and what to do next?

Not every loss of ranking visibility is a viable unfair ranking complaint under EU rules. Some position changes result from algorithmic optimization that Amazon has disclosed; some result from competitor advertising spend that has legitimately outbid the seller's own; some are consequences of listing quality factors the seller can address directly.

A complaint is most likely to have traction when: the ranking change was sudden, without advance notice, and without a statement of reasons from Amazon; the change is inconsistent with Amazon's own published ranking parameters; the change followed a specific event such as a shift in fulfilment method, a pricing decision, or an IP complaint; or there is a pattern across multiple sellers in the same category that suggests a systematic change rather than an individual listing issue.

A complaint is less likely to succeed on a P2B/DSA basis when: the seller's listing quality metrics have declined and the position change is proportionate to that decline; Amazon has published a general marketplace-wide ranking update that applies consistently; or the seller has previously received warnings about listing quality that are directly connected to the demotion.

The self-assessment checklist, briefly: Do you have evidence of a position change with date and time? Did Amazon send you a statement of reasons? Does the change match anything in Amazon's disclosed ranking parameters? Has the change materially affected your Amazon IT revenue? Did the change follow an identifiable operational event on your account? If the answers to the first, third, and fourth questions are yes and no and yes respectively, the complaint has a foundation worth pursuing.

If the seller described above is you – listings suppressed on Amazon IT, no explanation, and a business that depends on that Italian market visibility – the next step is to contact Tutamen for a short initial review of the specific facts. We assess whether the ranking change gives rise to a viable P2B and/or DSA complaint, identify the evidentiary gaps, and advise on the realistic path before any filing is made.

Frequently asked questions: unfair ranking complaints under EU rules on Amazon IT

How long does resolving unfair ranking complaint under eu rules usually take on Amazon IT?

The timeline depends on the route taken. An internal P2B complaint that is well-structured and specific can receive a substantive response within a few weeks; Amazon is required to operate its complaint-handling system within a reasonable time, though the P2B Regulation does not fix a single hard deadline. P2B mediation, if needed, adds several more weeks. Regulatory proceedings before the AGCM or at EU level typically run for months to years. Civil litigation in Italy involves the longest timeline. In matters we handle on Amazon IT, the internal P2B and DSA path tends to be the fastest route to a practical resolution for most sellers whose goal is to restore listing positions rather than to produce a regulatory finding.

What are the main risks if I handle unfair ranking complaint under eu rules alone?

The primary risk is filing the complaint through the wrong channel and failing to invoke the P2B Regulation by name, which means Amazon's response will not engage with its legal obligations and you will not build the procedural record you need for mediation or external escalation. A second risk is missing the evidentiary window: search position data, Buy Box status, and sales velocity evidence must be captured before it disappears from Seller Central's reports. A third risk is accepting a non-substantive response as a resolution, which forfeits the escalation path. DSA seller rights and P2B regulation give Amazon IT sellers genuine procedural protections, but those protections only function if they are invoked correctly and in sequence.

Do I need a lawyer for unfair ranking complaint under eu rules?

Not in every case. A seller who is familiar with the P2B Regulation and the DSA, who has preserved the evidentiary record, and whose complaint involves a clear and specific mismatch between Amazon's disclosed ranking terms and what was applied can file an effective internal complaint without professional help. The value of legal involvement increases significantly when the internal path produces a non-substantive response, when mediation is being considered, when the complaint has a DMA self-preferencing dimension, or when the commercial loss is large enough to justify civil proceedings. In our experience, the cost of a mis-filed or procedurally defective complaint – in time and in foreclosed options – is typically higher than the cost of getting the initial filing right. Fixed fees, quoted up front after a short review of the facts, are how we structure this work.
