How it works
SwipeRank has exactly one rule, and everything else follows from it: rank is earned by swipes and cannot be bought.
The score
Every product starts at 1000. Each swipe moves it Elo-style against a 1000-rated field, so the score settles at whatever the product’s real right-swipe rate deserves — roughly 1147 at 70% right, 1000 at 50%, 853 at 30%. The K-factor shrinks as swipe volume grows. Early swipes move the number fast; once a product has real volume behind it, a burst of votes can’t hold a score it hasn’t earned.
What money buys
A boost makes a card come up more often in the deck — up to 4x more likely for the window you pay for. That is the entire effect. It does not add points, it does not change your rank, and the card can still be swiped left by everyone who sees it. This is enforced in the database, not just in copy: the score column rejects any write that doesn’t come from a swipe. Boost code physically cannot touch it.
Backing someone else
Anyone can boost any product — you don’t have to own it. If you think something deserves more eyes, put it in front of more people. One boost runs per product at a time. Buying another replaces it rather than stacking, so multipliers never climb past 4x.
Pricing
Listing a product is $5, once, forever. It’s a spam filter more than a revenue line.
No accounts
There is no sign-up. When you list a product you get an edit token, stored in your browser, and that token is the only thing that can edit the listing. Clear your browser data and you lose the ability to edit — so keep the token somewhere if you care.
