We have purchased from hundreds of AliExpress sellers over three years of product testing. The difference between a 96% and 91% feedback score represents meaningful risk. Sellers below 95% have caused us the most disputes and delays. Understanding what the numbers mean prevents wasted time and money.
This guide covers how to verify seller reliability using feedback scores, detailed ratings, store history, and review analysis. We also explain how to spot fake reviews and interpret the DSR scoring system.

Why checking seller reliability matters
AliExpress hosts millions of sellers with varying levels of quality and honesty. The platform cannot verify every seller’s intentions during registration, so some dishonest operators exist alongside legitimate businesses.
Consequences of choosing an unreliable seller:
| Problem | Impact |
|---|---|
| Product does not match description | Dispute required, partial refund possible |
| Long shipping delays | Weeks of waiting, uncertain delivery |
| Non-delivery | Full dispute process, 15+ days to resolve |
| Counterfeit item | May not qualify for full refund |
| Poor communication | No help when problems occur |
| Store disappears | Harder to resolve disputes |
Checking seller metrics before purchase takes 2-3 minutes. Resolving a dispute with a bad seller takes 2-3 weeks.
Check the positive feedback percentage
Every seller’s store page displays a positive feedback percentage calculated from all customer ratings over the past six months. AliExpress considers 4-star and 5-star reviews as positive.
Feedback percentage guidelines:
| Score range | Risk level | Recommendation |
|---|---|---|
| 98-100% | Low | Safe for any purchase |
| 95-97% | Low-Medium | Safe for most purchases |
| 90-94% | Medium | Proceed with caution, read recent reviews |
| 85-89% | High | Avoid unless no alternatives |
| Below 85% | Very High | Do not purchase |
Where to find the feedback percentage:
- Click the seller’s store name on any product listing
- View the percentage displayed prominently on the store page
- Check the Feedback tab for the full breakdown
A seller with 97% positive feedback and 10,000 orders is more reliable than one with 99% and 50 orders. Volume matters alongside the percentage.
Understand detailed seller ratings (DSR)
The Detailed Seller Ratings break down performance into three categories, each scored from 1 to 5 stars:
| DSR category | What it measures |
|---|---|
| Item as Described | Product matches listing photos and description |
| Communication | Response speed and helpfulness |
| Shipping Speed | Time from order to dispatch |
AliExpress displays each score alongside the platform average for comparison. Scores marked “above average” in green are good. Scores marked “below average” in red warrant caution.
How DSR scores are calculated:
Each rating contributes points to the seller’s overall feedback score:
- 5 stars or 4 stars = +1 point
- 3 stars = 0 points
- 2 stars or 1 star = -1 point
The DSR percentage shown represents the cumulative weighted average over six months.
DSR score interpretation: what the numbers actually mean
Competitors mention DSR scores but rarely explain what specific numbers indicate. Here is a practical interpretation:
Item as Described score:
| Score | Meaning | Action |
|---|---|---|
| 4.8-5.0 | Products consistently match listings | Safe to buy |
| 4.5-4.7 | Minor discrepancies occasionally reported | Check recent reviews for specifics |
| 4.2-4.4 | Notable difference between listing and reality | Read negative reviews carefully |
| Below 4.2 | Frequent complaints about accuracy | Avoid this seller |
Communication score:
| Score | Meaning | Action |
|---|---|---|
| 4.7-5.0 | Fast, helpful responses | Good for complex orders |
| 4.4-4.6 | Adequate communication | Acceptable for simple orders |
| Below 4.4 | Slow or unhelpful responses | Expect no help if problems arise |
Shipping Speed score:
| Score | Meaning | Action |
|---|---|---|
| 4.7-5.0 | Ships within 1-3 days | Reliable dispatch times |
| 4.4-4.6 | Ships within 3-5 days | Standard performance |
| Below 4.4 | Frequent dispatch delays | Expect longer waits |
Red flag combinations:
If a seller has high overall feedback (95%+) but a low “Item as Described” score (below 4.5), their products likely have quality issues even though shipping is fine. This specific mismatch is more telling than the overall percentage.
Check store age and order history
Store age indicators:
| Store age | Reliability indicator |
|---|---|
| 4+ years | Established, proven track record |
| 2-3 years | Experienced, generally reliable |
| 1-2 years | Moderate experience |
| Under 1 year | New seller, limited history |
New stores are not automatically unreliable, but they lack the track record to verify. For expensive items ($25+), prefer sellers with 2+ years of operation.
Finding store age:
- Go to the seller’s store page
- Look for “X years” displayed near the store name or in the store info section
- Some stores display the exact opening date
Orders shipped:
The total number of orders shipped indicates experience and volume. Higher numbers suggest:
- More customer feedback to evaluate
- Established supply chain
- Less likely to disappear suddenly
| Orders shipped | Indication |
|---|---|
| 10,000+ | High-volume, established seller |
| 1,000-10,000 | Moderate experience |
| 100-1,000 | Limited track record |
| Under 100 | Very new or low-volume |
Look for Top Brand and verification badges
AliExpress awards badges to sellers meeting specific criteria:
Top Brand badge:
- Awarded to official brand stores or authorized resellers
- Undergoes platform verification
- Maintains consistently high ratings
- Resolves issues quickly to protect status
Guaranteed Genuine badge:
- Product verified as authentic
- Full refund (including shipping) if counterfeit
- Seller faces penalties for violations
Choice badge:
- Featured in AliExpress Choice program
- Fast shipping (often from local warehouses)
- Simplified returns
Where to find badges:
- On product listings, next to the seller name
- On the store page header
- In search results, displayed as icons
Badges provide an extra layer of verification but should not replace checking DSR scores and reviews.
Read buyer reviews (focus on photos and specifics)
Product reviews reveal real-world experience with the item and seller.
What to check in reviews:
| Review element | What it reveals |
|---|---|
| Customer photos | Actual product appearance vs listing photos |
| Specific measurements | Real dimensions compared to description |
| Shipping time mentioned | Actual delivery experience |
| Seller communication notes | How problems were handled |
| Return/refund experience | Seller cooperation on issues |
Review filters to use:
- “With Photos” or “With Pictures”: See actual products received
- “Verified Purchases”: Confirmed transactions, not fake reviews
- Star rating filters: Check 2-3 star reviews for balanced perspective
Reading negative reviews:
2-3 star reviews often contain the most useful information. Buyers who received products but had specific issues provide detailed feedback. Look for patterns in complaints (e.g., multiple buyers mentioning sizing runs small).
How to detect fake and manipulated reviews
Fake reviews exist on AliExpress. Sellers purchase review services or incentivize positive feedback. Detecting them protects your purchase decisions.
Signs of fake reviews:
| Red flag | Example | Why it’s suspicious |
|---|---|---|
| Generic praise without specifics | “Great product, fast shipping, A+++” | No actual product details |
| Perfect grammar in non-English markets | Flawless reviews on products sold primarily in non-English countries | Likely written by hired reviewers |
| All reviews posted in short timeframe | 50 reviews in 3 days on new product | Coordinated fake review campaign |
| Identical phrasing across reviews | Multiple reviews saying exact same sentence | Copy-paste from review template |
| 100% five-star on high-volume product | 500+ reviews, all 5 stars, no criticism | Statistically improbable |
| Photos look professional or staged | Studio lighting, perfect angles | May be seller-provided, not customer photos |
| Reviewer has no other review history | Account created just to leave one review | Fake account for review manipulation |
| Reviews copied from other listings | Same text appears on competitor products | Seller copied reviews from elsewhere |
Detection methods:
- Compare reviews across sellers: Search the same product from different sellers. If identical reviews appear on multiple listings, the reviews are fake.
- Google reverse image search: Right-click review photos and search Google Images. If the same photo appears on other sites or products, it was not taken by the reviewer.
- Check Q&A section: The question and answer section contains genuine buyer concerns. If many people ask “Is this actually [size/material/quality]?”, the listing may be misleading.
- Focus on 3-star reviews: Fake review services rarely create middling reviews. 3-star reviews with specific feedback are usually genuine.
- Check review dates vs order volume: A new product with dozens of detailed reviews in its first week is suspicious.
Test seller communication before buying
For items over $20 or complex products, message the seller before purchasing.
What to ask:
- Specific questions about the product (dimensions, materials, compatibility)
- Shipping method and estimated delivery time
- Return policy for your specific situation
Evaluate the response:
| Response quality | Indication |
|---|---|
| Fast (under 24 hours), detailed, helpful | Reliable seller who values customers |
| Slow (2-3 days), brief but accurate | Adequate for simple purchases |
| Very slow (4+ days) or no response | Will not help if problems arise |
| Vague, avoids direct answers | Possible issues with product accuracy |
Sellers who ignore pre-purchase questions will likely ignore post-purchase problems.
Warning signs: prices too good to be true
Unusually low prices indicate potential issues:
| Product category | Price red flag threshold |
|---|---|
| Brand-name electronics | 50%+ below retail price |
| Designer fashion | 70%+ below retail price |
| Watches with brand names | 80%+ below retail price |
| Memory cards/storage | 40%+ below market average |
What low prices often mean:
- Counterfeit product
- Lower quality than shown
- Bait-and-switch (different item shipped)
- Missing components or accessories
Compare prices across multiple AliExpress sellers for the same product. The median price range indicates realistic market value.
Understanding AliExpress seller symbols
AliExpress historically used medals, diamonds, and crowns to indicate seller reputation levels. The current system has evolved, but understanding these symbols helps interpret seller status.
Traditional reputation hierarchy:
- Medals: Entry-level sellers (newer, fewer transactions)
- Diamonds: Experienced sellers (moderate transaction history)
- Crowns: Top-tier sellers (high volume, excellent feedback)
Progression:
- 6 medals = 1 diamond
- 6 diamonds = 1 crown
Current indicators:
The platform now emphasizes:
- Percentage-based feedback scores
- DSR ratings
- Badge designations (Top Brand, Choice)
- Store age
Some store pages still display the medal/diamond/crown icons alongside newer metrics.
What to do if you receive a problem order
AliExpress Buyer Protection covers most purchase issues.
Protection coverage:
| Issue | Resolution |
|---|---|
| Order never arrives | Full refund if past estimated delivery |
| Product not as described | Partial or full refund with evidence |
| Counterfeit item | Full refund (report within 15 days of receipt) |
| Damaged in shipping | Partial or full refund with photos |
Dispute process:
- Contact seller first through AliExpress messaging
- If unresolved within 3-5 days, open official dispute
- Provide evidence: photos, screenshots of listing, tracking info
- AliExpress mediates if seller does not agree
- Resolution typically within 15 days
Critical rules:
- Never close a dispute until you receive refund or replacement
- Never pay seller outside AliExpress platform
- Do not confirm delivery until you inspect the product
- Screenshot product listings before ordering (sellers can modify listings)
Browser extensions for seller verification
Several free browser extensions automate seller checking:
AliTools:

- Shows price history
- Compares similar products across sellers
AliHelper:
- Calculates store reliability score
- Shows DSR breakdown automatically
- Tracks price changes over time
Megabonus:
- Displays seller reliability indicators

These tools aggregate data you could find manually but save time when browsing multiple products.
Quick seller verification checklist
Before purchasing, verify these items:
| Check | Minimum threshold |
|---|---|
| Positive feedback percentage | 95% or higher |
| Item as Described DSR | 4.5 or higher |
| Store age | 1+ year (2+ for expensive items) |
| Orders shipped | 100+ (1000+ for expensive items) |
| Recent reviews with photos | Available and match listing |
| Response to message (expensive items) | Within 24-48 hours |
If a seller fails multiple checks, find an alternative. The same product is almost always available from multiple sellers.
Final thoughts
Seller verification on AliExpress takes minutes but saves significant frustration. The feedback percentage provides a quick filter, but DSR scores reveal specific strengths and weaknesses. A 96% overall rating with a 4.3 “Item as Described” score is less reliable than a 94% seller with 4.8 across all DSR categories.
Fake reviews exist, but they follow detectable patterns. Generic praise, identical phrasing, and professional photos without real-world context indicate manipulation. Focus on 3-star reviews and customer photos for genuine feedback.
For items under $10, basic verification (95%+ feedback, reasonable DSR) is sufficient. For expensive items, add the communication test and verify badge status. The extra 5 minutes of checking prevents the 2-3 weeks a dispute resolution requires.
FAQ
1. What is a good seller rating on AliExpress?
A positive feedback score of 95% or higher indicates a reliable seller. For the Detailed Seller Ratings (DSR), look for scores of 4.5 or above in all three categories: Item as Described, Communication, and Shipping Speed. Sellers with 98%+ feedback and 4.7+ DSR scores across 1,000+ orders represent the lowest risk.
2. How can I tell if AliExpress reviews are fake?
Fake reviews often contain generic praise without specific product details, identical phrasing across multiple reviews, all-positive ratings with no criticism, or professional photos that look staged. Compare reviews across different sellers for the same product. If identical reviews appear on multiple listings, they are fake. Google reverse image search on review photos can reveal if images were copied from elsewhere.
3. What do the medals, diamonds, and crowns mean on AliExpress?
These symbols represent seller reputation tiers based on transaction history and feedback. Medals indicate entry-level sellers, diamonds indicate experienced sellers, and crowns indicate top-tier sellers with high volume and excellent feedback. Six medals equal one diamond, and six diamonds equal one crown. The current AliExpress system emphasizes percentage-based feedback and DSR scores alongside these traditional symbols.
4. How do I check a seller’s detailed ratings (DSR)?
Visit the seller’s store page by clicking their store name on any product listing. The DSR scores appear in the Feedback section, showing three categories: Item as Described, Communication, and Shipping Speed. Each is rated 1-5 stars and compared to the platform average. Scores marked “above average” in green indicate better-than-typical performance.
5. What should I do if a seller sends the wrong item or a fake product?
Contact the seller first through AliExpress messaging. If they do not resolve the issue within 3-5 days, open an official dispute through Order Details. Provide evidence including photos of what you received, screenshots of the original listing, and tracking information. AliExpress Buyer Protection covers full refunds for non-delivery and partial or full refunds for items not as described. Do not close the dispute until you receive your refund or replacement.
