The click number is the product — it is what justifies a second bid. So here is exactly how it is made, including the parts that are imperfect.
A click is one verified visitor departure from a listing to its destination, passing through this site's outbound redirect. Each visitor counts once per listing per day: a second visit the same day changes nothing, and the same visitor counts again tomorrow. Page views, impressions and hovers never count — only leaving, toward the thing the listing promotes.
Requests identifying as crawlers, preview fetchers, monitors or automation tools — and requests with no browser identity at all — are excluded from the public count and tallied separately as rejected bot traffic. Bot filtering is pattern-based, so a bot impersonating a real browser can evade it; deduplication then still caps what any single source can add: one per day.
No raw IP address is ever written to the database — not for visitors, not for bidders. Deduplication works from a one-way salted hash of the visitor's address, the listing and the date. The date is part of the hashed input, so each day produces unrelated digests, and the hashes themselves are purged after 48 hours — they only need to live long enough to recognise a repeat visit within the same day. What survives is the daily aggregate count per listing, which is the evidence base for the number on the board.
One honest caveat: the salt is a fixed secret, not a rotating one. Rotation is open work; until then this is a strong pseudonymisation, not a cryptographic guarantee.
The seven-day figure printed on every card is computed from the same aggregates the listing's owner sees on their own page. There is no flattering private number, and no way for us to quietly show a buyer a bigger one. Per-visitor forensics are deliberately impossible after 48 hours; the durable aggregate log is the whole story, for you and for us. The rules around removal and refunds live in the listing policy.
