What to know about unfair ranking complaint under EU rules

TL;DRAn unfair ranking complaint under EU rules gives Amazon IT sellers a formal legal mechanism to challenge unexplained demotion or suppression of their listings on the Italian marketplace. The Platform-to-Business (P2B) Regulation requires Amazon to publish transparent ranking criteria and to justify departures from them; the Digital Services Act (DSA) adds internal complaint-handling obligations that apply to Amazon as a designated Very Large Online Platform (VLOP). These instruments are not advisory guidance – they carry enforceable rights that sellers can and do invoke.

If you have woken up to a rankings collapse on Amazon.it and cannot find a clear reason in Seller Central, you are not alone. As enforcement automation has tightened across EU marketplaces, unexplained visibility losses have become one of the most common account-health events we see in our practice. This page answers the questions sellers actually ask on day one.

The structure: what the complaint mechanism actually is, which rules apply, how the process works step by step, the real decision points and trade-offs, and what happens if the first internal complaint is rejected.

What exactly is an unfair ranking complaint under EU rules?

An unfair ranking complaint under EU rules is a formal objection that a marketplace seller submits to a platform – here, Amazon Italy – asserting that a change to the visibility or position of its listings violates the transparency and non-discrimination obligations the platform owes under EU law.

The legal basis is layered. The Platform-to-Business (P2B) Regulation requires Amazon to set out in its general terms the main parameters that determine ranking and the reasons why those parameters matter relative to one another. If Amazon applies a ranking treatment – a demotion, a suppression, a change to which listings surface in search – without explaining why, or if that treatment contradicts the criteria Amazon has published, the regulation gives sellers a right to complain. A "ranking complaint" is the formal exercise of that right.

The DSA adds a second layer. Amazon's designation as a Very Large Online Platform means it must operate an internal complaint-handling system that is accessible, effective, and free of charge. When a seller submits a complaint about ranking, Amazon must process it in a non-discriminatory manner and explain any decision that rejects it. "Non-discriminatory" is not empty language – it means the same substantive standard applies regardless of whether the seller is a third-party seller or a category in which Amazon's own retail arm competes.

In practice, the complaint targets a specific listing-level or account-level event: a sudden drop in organic position, a removal from the Buy Box algorithm's pool, a suppression linked to a product-compliance flag, or a demotion following an IP complaint that has since been retracted. What sellers often miss is that a complaint must be precise. A generic objection to "unfair treatment" is unlikely to generate a substantive response. The complaint has to map the event to the platform's own published ranking criteria and explain the discrepancy.

Which EU rules actually apply on Amazon Italy?

Three instruments are most relevant to a ranking dispute on Amazon.it: the P2B Regulation, the DSA, and the Digital Markets Act (DMA), with each playing a different role depending on the nature of the complaint.

The P2B Regulation is the most targeted instrument. It applies directly to online intermediation services operating in the EU and imposes ranking-transparency obligations that Amazon must meet regardless of which marketplace the seller uses. For Italian sellers – and for sellers established elsewhere who sell on Amazon.it – the Regulation's requirements apply to the terms and the ranking criteria Amazon publishes for EU sellers. The Regulation explicitly requires that differentiated treatment between Amazon's own products and third-party seller listings, where it exists, must be disclosed.

The DSA applies to Amazon in its capacity as a Very Large Online Platform. The internal complaint-handling obligation under the DSA means that a seller who submits a ranking complaint is entitled to receive a reasoned decision. The DSA also requires Amazon to offer out-of-court dispute settlement through certified dispute settlement bodies for matters that fall within its scope. That option becomes relevant when internal complaint-handling has been exhausted.

The DMA is narrower in daily application but matters in a specific class of disputes: those involving differentiated treatment of Amazon's own retail listings versus third-party sellers in the same product category. Under DMA gatekeeper obligations, Amazon is prohibited from treating its own services and products more favorably than comparable third-party services in ranking. If a ranking loss appears connected to a category where Amazon's retail competes directly, the DMA adds substantive prohibitions on top of the transparency obligations in the P2B Regulation.

For the eu marketplace suspension dimension – where a ranking demotion is accompanied by, or leads to, a listing suppression or account restriction – the interplay between these instruments and Amazon's own policies becomes important. A suppression that Amazon characterizes as a policy enforcement decision may still be subject to the DSA's statement-of-reasons obligation. We explore that connection further in the section on procedural steps below.

One practical note on jurisdiction: Amazon Italy operates under Amazon's EU structure, and Italian sellers receive their terms of service from an Amazon entity that is subject to EU law. For a broader understanding of the regulatory regime that governs all EU marketplace sellers, including background on how the P2B Regulation and DSA interact, the EU marketplace regulation complete guide for sellers sets out the full picture.

How does the complaint process actually work?

The process has four practical stages: documenting the event, submitting the internal complaint, escalating to out-of-court settlement if the internal path fails, and – in the right cases – considering litigation or regulatory referral.

Stage one is documentation. Before anything else, capture the record. Ranking in Seller Central shifts, and so does the evidence. Screenshot the affected listing pages with timestamps, export any account-health notifications or policy warnings that appeared around the time of the demotion, and pull the Business Reports data showing the visibility change. The complaint will need to describe the ranking event in concrete terms: which ASINs, which search terms, what position before and after, and what – if any – notification Amazon sent.

This step is where sellers most often lose ground early. A complaint submitted without a documented baseline is a complaint that Amazon can reject on procedural grounds without engaging with the substance. A complaint that cites specific rank positions, specific dates, and specific product categories puts Amazon in the position of having to explain the discrepancy against its own published criteria.

Stage two is the internal complaint under the DSA framework. The complaint goes to Amazon's internal complaint-handling system. It should reference the P2B Regulation's ranking-transparency requirements and the DSA's obligation to provide a reasoned response. It should identify the specific ranking criteria Amazon has published for the Italian marketplace and explain why the observed treatment either (a) contradicts those criteria or (b) was never adequately explained in the notice Amazon provided. The tone is factual and regulatory, not adversarial. Amazon is being asked to account for a specific action against a specific legal obligation – not to exercise discretion in the seller's favor.

Stage three is external escalation. If Amazon's internal complaint-handling produces no substantive response, or produces a rejection that does not engage with the regulatory argument, the DSA provides a path to out-of-court dispute settlement through a certified dispute settlement body. This body is neutral, and the process is free of charge to the seller. It is not litigation; it is a structured dispute-resolution process that generates a reasoned outcome. Amazon is required to engage with it in good faith. The outcome of that process can itself become evidence in a subsequent regulatory complaint or litigation.

Stage four – regulatory referral or litigation – is for cases where the conduct is systematic. A single ASIN demotion rarely warrants a direct referral to a national competition authority or to the European Commission. But a pattern of differentiated treatment in a category where Amazon competes directly – particularly where the DMA's gatekeeper obligations appear to have been violated – is a different matter. In our practice we see this analysis arise most often when a seller is losing visibility across an entire product line at the same time Amazon's own retail is gaining position in that line.

The German marketplace suspension guide covers how EU suspension and delisting events interact with the formal complaint process in a related context. The structural analysis applies across EU marketplaces, including Amazon.it.

For the steps specific to handling a suspension event on a German marketplace – which often runs in parallel with a ranking dispute when the suppression is tied to a compliance flag – the guide to handling a German marketplace suspension on Amazon DE is directly relevant to the procedural logic.

What are the real decision points for a seller?

An unfair ranking complaint involves genuine trade-offs, and the right path depends on the specific nature of the ranking event, the commercial scale of the impact, and the seller's position in the relevant category.

Decision one: is this a ranking event or a suspension event? Ranking demotions and listing suppressions can look similar in Seller Central but have different procedural triggers and different remedies. A pure ranking demotion – where the listing is still active but visibility has dropped – maps most directly to P2B Regulation and DSA complaint rights. A suppression – where the listing is inactive or ineligible for the Buy Box – may involve Amazon's policy enforcement mechanism, in which case the statement-of-reasons obligation under the DSA becomes the entry point rather than the P2B ranking-transparency obligation. Identifying which event has occurred determines which complaint path to use first.

Decision two: how time-sensitive is the commercial damage? Ranking loss compounds. Every week a seller's ASINs are demoted, the listing's click history and conversion history are degrading, and organic rank recovery – even after a successful complaint – takes time. If the impacted category is seasonal, or if inventory cost exposure is significant, the pace at which a complaint moves matters as much as whether it succeeds. Internal complaint-handling under the DSA is measured in weeks rather than months for most cases, but it is not instantaneous. Sellers with acute cash-flow exposure sometimes need to pursue interim measures in parallel with the formal complaint.

Decision three: should you escalate before exhausting internal remedies? Generally, no. Out-of-court settlement bodies under the DSA expect the internal process to have been attempted. Regulatory bodies expect the same. Moving to external escalation without a documented internal complaint submission weakens the seller's procedural record. The exception is where the ranking event is accompanied by an account restriction that has an imminent disbursement consequence – in that case, the funds-hold analysis may need to run in parallel with the ranking complaint.

A micro-case helps illustrate the decision logic. A mid-sized homewares seller on Amazon Italy (winter 2026) contacted us after noticing that its bestselling product line had dropped from consistent top-three organic placement to the second page within ten days. No account-health notification had been issued. The seller's Business Reports showed the change aligned with the date Amazon's own retail brand added a competing product to the category. We reviewed the P2B ranking criteria Amazon had published for EU sellers, documented the coincidence of timing, and built an internal complaint framing the discrepancy against the published criteria and the DMA's gatekeeper non-discrimination obligation. The complaint generated a substantive written response from Amazon within the statutory window – something the seller had not received through informal Seller Central contacts. The matter is ongoing, but the formal complaint opened a documented record for further escalation if needed.

The myth worth addressing directly is the belief that EU sellers have no leverage once a platform has acted. That framing reflects the pre-P2B Regulation world, where sellers had no formal right to an explanation of ranking decisions and platforms could characterize any demotion as a proprietary algorithm matter. The P2B Regulation explicitly changed that. Amazon's published ranking criteria are contractual commitments under that regulation, and a departure from them that harms a specific seller is a justiciable event – not a discretionary platform call that the seller simply has to accept.

What does a well-constructed internal complaint contain?

A well-constructed internal complaint under the DSA framework contains four elements: a precise description of the event, a regulatory reference map, a factual discrepancy statement, and a clear request for a reasoned response.

The event description is the foundation. It identifies the specific ASIN or ASINs, the marketplace (Amazon.it), the date range in which the ranking change occurred, the position change in measurable terms drawn from Business Reports, and any account-health or policy notification that coincided with the change. Where the complaint alleges differentiated treatment against a competing Amazon retail listing, the competing ASIN should be identified and its position noted alongside the seller's.

The regulatory reference map ties the factual narrative to specific obligations. The P2B Regulation's ranking-transparency requirement is cited with the observation that the change was not preceded by an explanation consistent with Amazon's published criteria. The DSA's statement-of-reasons obligation is cited with the observation that no reasoned notification was received. Where the DMA applies, the non-discrimination obligation for gatekeepers is cited. This is not legal argument for its own sake – it is the signal that the complaint is a formal regulatory exercise and not an informal support ticket.

The discrepancy statement is the substantive heart of the complaint. It explains, in factual terms, why the observed ranking treatment is inconsistent with the criteria Amazon has published. This requires having read and internalized Amazon's actual published criteria for the EU marketplace before drafting. Generic assertions of unfairness are not discrepancy statements. Specific comparisons between the criteria and the observed outcome are.

The request is concrete: a written, reasoned response explaining the basis for the ranking treatment and confirming whether that treatment will be maintained or reversed. The DSA does not require Amazon to reinstate the seller's position – it requires Amazon to explain. That explanation, if and when it arrives, becomes the evidence base for the next stage of escalation.

In matters we handle, the drafting discipline of the internal complaint is usually the single largest determinant of whether the process generates useful output. A complaint that Amazon can characterize as a general grievance gets a form response. A complaint that maps a specific event to a specific regulatory obligation, with documentation, is harder to dismiss without substantive engagement.

What happens after an internal complaint is rejected or ignored?

If Amazon's internal complaint-handling produces a non-substantive response, a rejection without adequate reasoning, or no response within a reasonable time, the seller's next step is out-of-court dispute settlement under the DSA framework.

The DSA requires Amazon, as a Very Large Online Platform, to offer sellers access to certified out-of-court dispute settlement bodies for matters within the scope of Amazon's internal complaint-handling obligations. The body selected must be impartial, and the process must be free of charge to the seller. The outcome is not automatically binding on Amazon in every jurisdiction, but the body issues a reasoned recommendation. Amazon is required to engage with the process in good faith, and a refusal to do so or a pattern of disregarding recommendations is itself a compliance concern that national Digital Services Coordinators and the European Commission monitor.

From a practical standpoint, the out-of-court process does several things for a seller even if it does not produce immediate reinstatement of ranking. It creates a documented external record of the dispute. It forces Amazon to respond in a structured process to a neutral third party rather than through a Seller Central support ticket. And it establishes the procedural foundation for a regulatory complaint to a national authority if the conduct appears systematic or if the DMA's gatekeeper obligations appear to have been violated at scale.

What should a seller do if a first attempt at the internal complaint already failed? If you have already been through the internal process and received a rejection that does not engage with the regulatory argument, a second read of the complaint and Amazon's response can identify the specific gap – whether the complaint was too generic, whether the documentation was incomplete, or whether Amazon's response itself contains a procedural failing that can be leveraged in the out-of-court process. In our practice, a rejected first complaint is frequently the starting point, not the endpoint. The question is what the rejection reveals about where the argument needs to be sharpened.

Frequently asked questions

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

Timelines depend on which stage the matter reaches. An internal complaint under the DSA framework typically generates a formal response within several weeks in well-documented cases; Amazon's obligations under the regulation require it to process complaints within a defined period, and the practical experience in matters we handle is that a substantive response – not necessarily a favorable one – usually arrives faster than sellers expect when the complaint is precisely framed. Out-of-court dispute settlement takes longer, typically several months from initiation to recommendation, depending on the certified body and the complexity of the factual record. Regulatory referral or litigation operates on a much longer timescale and is reserved for cases involving systematic conduct or material financial harm at scale. The commercial urgency of the ranking loss – particularly in seasonal categories – is one reason early intervention on the documentation and complaint-drafting stage matters disproportionately.

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

The primary risk is procedural: a poorly framed internal complaint forecloses the external escalation path or weakens it materially. The DSA and P2B Regulation give sellers formal rights, but those rights are only as effective as the complaint that exercises them. A generic support ticket submitted through Seller Central does not constitute a formal DSA complaint; it does not create the documented record needed for out-of-court settlement; and Amazon has no obligation to treat it as a regulatory complaint. Beyond framing, sellers who handle ranking complaints alone often miss the distinction between a ranking event under P2B and a listing suppression under the DSA's statement-of-reasons obligation – using the wrong instrument for the wrong event produces delays and usually a form rejection. The second major risk is timing: if the ranking event coincides with a reserve or disbursement issue, handling the complaints in the wrong sequence can compound the financial exposure rather than contain it.

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

There is no legal requirement to have a lawyer to submit an internal DSA complaint or to initiate out-of-court dispute settlement. The DSA explicitly preserves the seller's right to proceed independently. That said, the practical value of attorney involvement depends on the scale of the impact and the complexity of the factual record. For a single-ASIN demotion with limited commercial impact, a well-researched self-prepared complaint can be effective if the seller has taken the time to understand the P2B ranking criteria and the DSA's complaint requirements. For matters involving multiple ASINs, significant revenue exposure, a potential DMA differentiated-treatment argument, or a history of prior complaints that were rejected, attorney involvement in the complaint-drafting stage produces materially better outcomes in the matters we have handled. The question to ask is not whether legal involvement is required, but whether the cost of getting the complaint wrong – in terms of the procedural record it creates for escalation – exceeds the cost of getting professional input at the outset.

Can Amazon retaliate for submitting a formal EU ranking complaint?

The DSA explicitly prohibits platforms from treating users less favorably because they have submitted a complaint or used their rights under the regulation. That prohibition applies to Amazon Italy as much as to any other VLOP. In practice, this means that a well-documented formal complaint does not create retaliation risk in the regulatory sense, because any adverse account action taken after the submission of a complaint would itself be a DSA compliance concern. Sellers are understandably cautious about this, and the caution reflects a pre-regulatory era when platforms could respond to disputes informally and without constraint. The regulatory architecture has changed that, at least for EU-based transactions. Documenting the timeline of the complaint and any subsequent account events is therefore part of good practice, both to protect the seller's record and to create evidence for the escalation path if needed.

What if the ranking demotion appears linked to an IP complaint that was later retracted?

A ranking demotion or listing suppression that followed an intellectual-property complaint – and that persisted after the complaint was retracted – is a factually distinct event with its own complaint logic. Under the DSA, Amazon owes a statement of reasons for restrictions it applies; if the restriction was based on a complaint that has since been retracted, the continued restriction requires its own justification. Under the P2B Regulation, if the continued demotion is not explained by any of Amazon's published ranking criteria, the transparency obligation applies. In the matters we handle involving retracted IP complaints, the issue is frequently that Amazon's systems did not automatically restore the prior ranking once the complaint was withdrawn, and Amazon did not provide an explanation for the gap. That combination – suppression after retraction, no explanation – is precisely the factual scenario the internal complaint mechanism is designed to address. A complaint in those circumstances should document the retraction, the date it took effect in Seller Central, and the ranking data before and after the retraction date.
