How Fyndare works
Our data methodology in plain language: where the codes come from, what gets pruned, what the numbers mean — and what we refuse to claim.
Where the offers come from
Fyndare syncs coupon codes and deals directly from the affiliate feeds of major retail networks — the same systems retailers use to publish their own promotions — plus a small amount of hand-curated content. Nothing is scraped from other coupon sites and nothing is crowd-submitted anonymously, which is where most dead codes on the web come from.
Synced and pruned, not “verified”
Every sync does two things: it adds new offers the retailer just published, and it removes offers that have disappeared from the retailer's feed. Codes past their expiry date deactivate automatically. That is the honest claim we can make — each page shows when its store was last synced, and every offer shows the real expiry date from the retailer's feed. We deliberately never stamp codes “verified”: no coupon site tests every code at every checkout, and pretending otherwise is the industry's oldest trick.
The event ledger
Behind the catalog, Fyndare keeps a running ledger of every code's lifecycle — when it appeared, changed, expired, vanished from the feed, or came back. Over time this becomes real per-retailer intelligence: how often a store drops new codes, how long they typically live, and how deep the discounts actually run. As that history accumulates, we publish it on store pages as dated, sourced statistics.
What the success rates mean
After trying a code, shoppers can report whether it worked. A code showing “90% success (30 votes)” worked for 27 of the 30 shoppers who reported back. New codes start unrated instead of with an invented score, and codes are ranked by a confidence score combining success rate, how recently the code was confirmed working, and listing recency — never by what a retailer pays us.
How the site makes money
Through affiliate commissions: when you buy after clicking a store link, the retailer may pay us a commission at no extra cost to you. Commissions never affect which codes appear or how they rank — ranking is driven entirely by the data above. Every outbound link is disclosed and marked as sponsored.
