Unauthorized seller
A listing that uses the brand name or a product image is compared with your authorized seller list. Sellers not on the list are flagged.
Find counterfeit listings and unauthorized sellers on marketplaces.
Authex marketplace monitoring is an online brand-monitoring solution that detects listings and unauthorized sellers using your brand on marketplaces in Türkiye and abroad, collects the evidence and reports it. For each finding it prepares the evidence file and a draft of the platform complaint; the brand's team or its lawyer decides whether to file it and files it.
Overview
What is marketplace monitoring?
Marketplace monitoring means checking, on a regular schedule, who uses your brand name, product names and product photos in marketplace listings, and how. Authex runs these checks on 14 marketplaces and classifieds platforms in Türkiye, including Trendyol, Hepsiburada, n11 and Amazon.com.tr, and abroad on the platforms you choose from more than 100 marketplaces and country storefronts, including Amazon country stores and eBay.
Every listing it finds is compared with your authorized seller list and your official product photos. A seller missing from the list or a listing that reuses the brand's images without permission becomes a finding; if you have entered a price band for the product, a price outside it is added to that finding as a label. The listing is captured as it stands, with a screenshot and the source link.
Storefronts of sellers flagged as unauthorized and risky are scanned directly in later runs, which surfaces listings that never mention the brand in the title. Confirmed findings reach the brand's team or lawyer with the evidence file and the complaint draft already prepared.
Scope
Which marketplaces does it scan?
In Türkiye, 14 marketplaces and classifieds platforms are scanned, including Trendyol, Hepsiburada, n11 and Amazon.com.tr. Abroad, you choose from more than 100 marketplaces and country storefronts, including Amazon country stores and eBay. The brand chooses which platforms and countries are scanned.
Detection
What it catches.
Counterfeit product
Listing images are compared with the brand's official photos and logo by image similarity, and text analysis looks for counterfeit signals.
Price deviation
If a price band has been entered for the product, a price outside it on a flagged listing gets an extra label, with currencies converted.
Image theft
Listings that use the brand's photos without its name are found by reverse image search.
Evidence
What is in the evidence file?
- Full-page screenshot, capture time and file hash (SHA-256)
- Listing address, product images and price
- Seller name
- On Trendyol, Hepsiburada, n11, Çiçeksepeti, Pazarama, PttAVM and Beymen, the seller's legal company details: trade name, tax ID, tax office and address
- First and last seen dates, recurring finding flag
- A detection note when the barcode, GTIN or product code differs from your catalog
Process
How does it work?
Brand and products are defined
The brand name, product names, official product photos, barcodes and product codes go into the system; an expected price band per product can be added too.
Authorized sellers are added
Your authorized seller and dealer list is uploaded; stores on that list never produce findings.
Platforms and frequency are chosen
You pick the marketplaces, countries and scan frequency; scans run on schedule and can also be started by hand.
Listings are compared
Listings are assessed against the authorized seller list, image similarity and the listing text.
Your team decides
Findings are ranked by risk level; the brand's team confirms, reviews or dismisses each one.
Evidence file and draft are prepared
For a confirmed finding, Authex prepares the evidence file and a draft notice. The brand's team or lawyer files the complaint, and Authex keeps checking whether the listing stays online.

FAQ
Questions about Marketplace Monitoring
Does Authex take the listing down?
Authex detects the listing, collects the evidence and, for each finding, prepares the evidence file and a complaint draft. The brand's team or its lawyer decides whether to file it and files it; the platform decides on removal. After the report, Authex keeps tracking whether the listing stays online.
Which marketplaces does it scan?
In Türkiye, 14 platforms including Trendyol, Hepsiburada, n11 and Amazon.com.tr. Abroad, the platforms you choose from more than 100 marketplaces and country storefronts, including Amazon country stores and eBay. The brand chooses which countries are scanned.
Can my lawyer use the report?
Yes. The evidence file brings together the screenshot, capture time, listing URL, seller details and a file hash (SHA-256). Your lawyer can use the file for the platform report and for their legal assessment. For evidence to be used in court, a notarised capture is also recommended.
Do our authorized sellers' listings show up as findings?
No. Stores of companies on the authorized seller list do not produce findings.
How are unauthorized sellers of genuine products handled?
Not every unauthorized sale infringes a trademark: acts concerning products put on the market by the rights holder or with its consent fall outside the right, although the owner can stop the products being used commercially in altered or impaired form (Turkish Industrial Property Law No. 6769, art. 152). Authex presents the finding with its evidence, and claims in the listing such as “authorized seller” or “original” and unauthorized use of brand images show on it. The brand's team or lawyer decides how to proceed.
