Managing reviews and reputation on Amazon and MercadoLibre
October 2, 2026
A one-star review lands on a Friday afternoon. The buyer says the product arrived incomplete. You know it was not incomplete, that they opened the box badly, or that they simply did not read the description. And there it sits anyway: first visible review, average dropping from 4.6 to 4.3, and the feeling that somebody just handed you an invoice you do not owe.
That moment is where a lot of sellers make the worst decision of their year. They message the buyer offering a refund in exchange for taking the review down. Or they hire somebody who “fixes” reviews. Or they hand out free product in exchange for five stars. All three violate platform policy, and all three carry the same possible consequence: account suspension. This is not a gray area. It is written down.
The useful conversation is a different one: understanding what each platform actually measures, which legitimate tools exist for asking and for reporting, and — above all — recognizing that most bad reviews are not fixed with policy, they are fixed with operations. A product that arrived late, stock that did not exist, a description that overpromised: that is not a reputation problem, it is a process problem showing up as reputation.
This article separates the two systems — Amazon’s and MercadoLibre’s, which have little in common — explains what you can and cannot do, and lands on where the root cause is visible. With the usual warning: review and reputation policies change often, and what counts is what the Seller Central help and MercadoLibre’s help for your country say today.
two systems measuring different things
The most common conceptual mistake is treating “reviews” as one subject. It is not.
Amazon separates two things. On one side are product reviews: the stars and comments attached to the product detail page, which is to say, to the ASIN. Those reviews belong to the product, not to you. If you sell on a shared page, you are inheriting — for better and for worse — the reviews other sellers of the same item collected. On the other side is seller feedback: the seller rating, which is yours and reflects how your own orders went.
MercadoLibre organizes its world around the seller. The heart of the system is the reputation thermometer, a color scale running from red to green that, according to what the platform publishes, is built on three operational metrics: claims that reach mediation, sales you cancel, and shipments dispatched late. Product opinions and purchase-experience ratings also exist, but the thermometer — what decides whether you are a MercadoLíder and how much the search engine shows you — feeds on how you deliver, not on how many stars somebody gave you.
That is the difference to internalize:
- On Amazon, a bad review is content about a product.
- On MercadoLibre, a claim is an operational event that moves an indicator.
That is why tactics do not transfer. On Amazon you can spend months fighting an unfair review while your account stays clean. On MercadoLibre, three cancellations for lack of stock in one bad month drop your thermometer color and push you down in search even if no buyer wrote a single word.
Glossary: stockout, when you run out of something to sell →what is prohibited, plainly
This section exists so the line is unambiguous. These are not recommendations: they are things the platforms explicitly forbid and that can cost you the account.
- Buying reviews. Paying anybody — a person, an agency, a Telegram group — to leave a review. Prohibited, and in several jurisdictions actionable off-platform as deceptive advertising.
- Incentivizing reviews. Offering free product, a discount, a refund, a gift card or any benefit in exchange for a review. Amazon has prohibited incentivized reviews since 2016, with one exception: its own Vine program, where the incentive is administered by Amazon and the reviewer has no commercial relationship with you.
- Asking for positive reviews. You cannot ask for “a five-star review” or condition the message on the experience having been good. Filtering who you ask — messaging only the happy buyers — is also prohibited.
- Package inserts asking for positive reviews or offering anything in return for a review.
- Offering a refund, a replacement or any compensation in exchange for the buyer removing or editing a negative review. This is the one most often done out of ignorance and one of the most clearly sanctioned.
- Reviews from family, employees, partners or your own account, and review swaps between sellers.
- Manipulating MercadoLibre’s reputation system with simulated purchases, your own accounts or any operation staged to inflate metrics.
We are not going to explain how any of these are done, because the point of the article is the opposite. It is also worth saying something uncomfortable: platforms detect these patterns better than most people assume, and the punishment does not always arrive the month you did it. It arrives in December, when you sell the most.
what you can legitimately do to ask for reviews
The legitimate path is narrower and duller, and it works.
On Amazon, the safest route is the “Request a Review” button inside the order in Seller Central. Amazon writes and sends the message; you do not edit it. That is exactly why it is the lowest-risk option: you cannot step outside policy by accident, and if the policy changes, the message changes on its own. The conditions Amazon has applied to this kind of message are narrow — a single request per order, inside a window of days after delivery — so check the terms currently live in your account before automating anything.
There is also Amazon Vine, the program where reviewers selected by Amazon receive product in exchange for an honest opinion. You do not choose who reviews or what they write, and reviews can come out negative. It is the only authorized way for an incentive to exist, precisely because you do not control it.
MercadoLibre has no equivalent review-request button. What it has is post-sale messaging, which exists to resolve doubts and problems, not to solicit ratings. And that is the key to Meli’s system: the best way to protect reputation is to stop the problem from happening. Dispatch within the window, do not cancel for lack of stock, answer questions before the purchase, and resolve issues by message before the buyer opens a claim.
how to respond to a review without making it worse
Responding publicly is a real tool, and it is almost always used badly. Three rules.
The response is not for the person who complained. It is for the shopper reading that review six weeks later, deciding whether to buy from you. That person is not evaluating who is right: they are evaluating how you react when something goes wrong.
Do not argue the facts in public. “It is false that it arrived incomplete” makes you look defensive even when you are correct. It works better to acknowledge, offer the path to a fix, and take the detail to the private channel. Something like: “We are sorry the order arrived that way. We are messaging you to replace it.” Short, no excuses, no adjectives.
Never condition the fix. The moment help depends on the review coming down, you crossed the policy line. The fix is offered because it is the right thing, not as a transaction. And in practice, a buyer who gets a clean resolution sometimes updates the review on their own, which is the only way that can legitimately happen.
There is a quieter fourth point: the public response is also where you can correct information for other readers. If three reviews say “no cable included”, and it genuinely does not include one because it never did, the problem is not the reviews: it is your content. Fix the listing and those reviews stop arriving.
what can be reported and what cannot
Both platforms have mechanisms for reporting content that breaks their own rules. They work, within narrow limits.
Broadly speaking, you can report a review that:
- Contains offensive, discriminatory or otherwise inappropriate content.
- Includes personal data, addresses or contact information.
- Is obviously about a different product — common on Amazon pages with badly merged variants.
- Is spam, promotion of another seller, or advertising.
- Talks exclusively about delivery or the carrier rather than the product, in the case of Amazon product reviews.
- Comes from evident manipulation of the system.
What is not reportable is the part that hurts most: the negative review from a real buyer who had a bad experience, or who simply did not like the product. That opinion is legitimate even when it feels unfair, and there is no route to delete it. Anybody offering to remove it for a fee is offering you something they either cannot do, or will do in a way that puts your account at risk.
On MercadoLibre, in the same spirit, there are claims the platform does not count against reputation under certain conditions — Meli’s own help details the cases, for example when the buyer changes their mind — but that is not a lever you pull or negotiate: it is a rule of the system. The practical route is to document every operation well, answer quickly through messaging, and leave the record inside the platform, because that is the only log mediation will read.
And again, the warning running through this whole article: moderation and counting criteria get adjusted frequently. Before resting a business decision on any of these rules, confirm it in each platform’s official help.
Glossary: lead time, the real time your replenishment takes →most bad reviews are an operational symptom
If you classify six months of negative reviews and claims, the pattern is usually dull and repetitive:
- The product arrived late, because dispatch went out past the window or because your supplier’s real lead time is longer than you assumed.
- The order was cancelled, because the stock the channel displayed did not exist in the warehouse.
- The product was not what the buyer expected, because the listing promised something the item does not deliver, or because the published variant does not match what shipped.
- The product arrived damaged, from insufficient packaging or a defective batch concentrated in one period.
None of those four is solved by writing nicer replies. They are solved in inventory, in catalog and with your supplier. Reputation is the thermometer, not the illness, and the name MercadoLibre gave its indicator is more literal than it looks.
So the useful question after a run of bad reviews is not “how do I remove them?” but “what changed in my operation four to six weeks ago?”. There is almost always a date.
how this reads in iqseller
Without decoration: iqseller does not manage reviews. It does not reply to comments, does not import them, does not moderate them and has no messaging inbox. That conversation happens in Seller Central and in MercadoLibre, and it stays there.
What the panel does is work on the causes that end up producing those reviews.
Inventory shows real available stock per channel — what you can genuinely sell right now, not nominal stock — across Amazon, Full, your own warehouses and the 3PL. The cancellation for lack of stock, which on MercadoLibre hits the thermometer directly, almost always starts with a number nobody looked at in time.
Alerts warns you when a SKU goes into critical stock or when a discrepancy appears between channels, which is the window to react before it becomes a cancelled order.
Catalog, with its Parent → Model → SKU tree, exposes listings that drifted out of alignment across channels: the same product described differently on Amazon and MercadoLibre, or a variant published on one channel with attributes that do not match. That misalignment is one of the most common sources of “this is not what I ordered”.
Forecast helps on the lead-time side: when to restock so you do not arrive late, using the real time your replenishment takes rather than the promised one.
And Profitability puts the cost on the table. A return is not just one less star: it is the real net margin of that sale — with commissions, FBA or Full fees, shipping and the VAT and withholding breakdown — turned into a loss. Seeing that number per SKU changes which product you fix first.
what is worth remembering
- Amazon measures product reviews and seller feedback separately; MercadoLibre measures fulfillment through the thermometer.
- Buying reviews, incentivizing them or asking someone to remove a negative one in exchange for something violates policy and can cost you the account. There is no safe version of those practices.
- The legitimate tools on Amazon are the review-request button and the Vine program. On MercadoLibre, delivering on time and resolving before the claim.
- Reply in public for the future reader, keep it short, do not argue, and take the detail private without conditioning anything.
- You report content that breaks rules, not a legitimate negative opinion.
- Most bad reviews are a symptom of inventory, catalog or supplier issues. That is where the real fix lives.
- Always confirm the current rules in Seller Central and MercadoLibre help: they change frequently and vary by country.
