AliScore Chrome Extension: Features, Setup and How to Read the Score

AliScore is a free browser extension that scores every AliExpress product from 0 to 10 the moment the page loads, alongside a seller trust score, a review split and a plain verdict. This is the maker's own guide to it — if you came looking for an AliScore review, read it as documentation from an interested party rather than an independent verdict: what appears on the page, how to install it in about thirty seconds, how to read each number, and — because this is where shopping extensions usually overclaim — exactly what it does not do. You can install it from the Chrome Web Store and follow along on a real listing.

What appears on an AliExpress product page

Once installed, open any product on aliexpress.com, aliexpress.us or aliexpress.ru. Within a moment of the page settling, a compact pill appears near the product title showing the score and a verdict. Tap it for the full insights card:

• Product score, 0–10, with a tier label: Excellent, Great, Good, Average or Poor.
• Verdict: Safe to buy (8.0 and up), Worth considering (6.0–7.9), Buy with care (4.0–5.9) or Risky (below 4.0).
• Seller trust score, 0–10, labelled Trusted, Reliable, Fair, Caution or Risky, from the store's positive feedback rate (70%) and follower count (30%).
• Review analysis: the positive-versus-negative split from AliExpress's public review statistics, the five-star share, the structured Quality and Value labels buyers chose, the things buyers mentioned most, and how many reviews included photos.
• Score breakdown: four bars — Quality, Sentiment, Review volume, Value — each with its own 0–10 value and weight, so a 7.4 propped up by a discount looks different from a 7.4 earned on quality.
• Warning signs, in plain English, with the number that triggered each: too few reviews, negatives above 10%, a store below an established seller's profile, weak value.

If the listing has no usable data — a brand-new product with no reviews — the card says not enough data. It never invents a number to fill the space.

What appears on search and category pages

Comparison happens on listing pages, so the badges are there too. On search results, the homepage feed, bundle, wholesale and category pages, each product card gets a score badge:

• An outlined badge is an estimate from what the card shows: rating, sold count, price. Hover it for a moment, or click, and it verifies against the review statistics and turns solid.
• "AliScore ?" means the card had no genuine signal to score — no rating, no sales — so no number is shown.
• Verified results are cached on your device for 72 hours, so scrolling back to a product costs nothing.
• The badges keep up with infinite scroll as new cards load.

At the top of a search or category page, a Best Deals row pulls the five highest-scoring visible cards into one strip with image, title, price and badge. It is scored from the cards alone, so use it as a shortlist to verify on the product page, not as a final answer. If nothing on the page can be scored, the row does not appear.

Installing it

1. Open the Chrome Web Store listing and press Add to Chrome. The same build installs in Edge, Brave and Opera.
2. Chrome shows the permission it needs: access to AliExpress sites, and storage for your settings and cache. Nothing else.
3. Open any AliExpress product. The pill appears near the title. Tap it.

There is no account, no sign-in and no configuration step. The popup has two things in it: a switch for the affiliate feature described below, and the version number.

The affiliate dialog

AliScore is free and funded by the AliExpress affiliate program. On your first product page, a dialog on the page explains this and asks whether you will allow the extension to re-open product pages through our affiliate link so the commission is credited. If you press Allow, a product page reloads once; you stay on the same product and the price is the same. It never does this on cart, checkout or order pages. If you press No thanks, nothing ever reloads. The switch lives in the popup and turns it off immediately, and there is an "Ask me again" link if you change your mind. The privacy policy has the full wording.

Reading the score

The score is four weighted components, each 0–10, then a confidence adjustment. The complete formula, with the actual thresholds, is on the how it works page, and there is an interactive Score Lab there where you can run it on numbers you invent. The short version:

• Quality (35%): the star rating, normalised. Highest weight because every listing has one; also the most inflated, which the other three exist to correct.
• Sentiment (25%): the positive share of reviews, penalised once negatives pass 10%, nudged up when the structured Quality label is strongly positive.
• Review volume (25%): a logarithmic curve over the review count — how much evidence there is.
• Value (15%): rating against price on a log scale, with small credit for a genuine discount. Lowest weight because a cheap bad product is still bad.
• Confidence dampener: below ten reviews the total is scaled down. A listing with one review keeps roughly half of whatever it earned. This is the rule that stops a five-star, one-review listing showing as Excellent.

When a score surprises you, open the breakdown. Nearly always, one component explains it, and it is usually the dampener or a high negative share.

What it does not do

• No price history. AliScore does not track prices over time or draw charts. Its Value component scores rating against today's price. For a price chart, use a tool built for that; see the extensions guide.
• No fake-review detection. It cannot tell you a specific review is fake. It measures the shape of the review history — count, negative share, photo count, labels — which is what can honestly be measured.
• No account, no tracking, no analytics. The score is computed in your browser from the page you opened and from AliExpress's own public review endpoint. Review lookups go directly from your browser to AliExpress; nothing is sent to any server we operate.
• Nowhere but AliExpress. The host list is AliExpress domains only. It cannot run on any other site.

Browsers and versions

The Chrome build installs on Chrome, Edge, Brave and Opera. A Firefox build exists and its listing will be linked here when it is live. Both are Manifest V3. The current version is shown in the site footer and in the popup.

When something is wrong

No score on a page: reload once, since AliExpress is a single-page app and a slow render can outlast the first injection. "Not enough data": that is the honest answer for a listing with no history. A badge that stays hollow: hover or click to verify. Anything else, with the product URL and your browser, goes to the address on the support page — one person maintains this and reads every report.
