## FAQ (quotable)

### What is Biddr?
Biddr is a public pay-to-rank leaderboard on biddr.lol. You list a product URL or X handle and bid in US dollars. Rank equals the bid. The highest bid holds #1.

### Is Biddr an outbid.lol alternative?
Yes. Biddr follows the same bid-to-rank mechanic that made outbid.lol viral: money sets position, the board is public, and there is no quality algorithm. Biddr is a separate site with its own board and early pricing.

New listings start at $1. Rank depends on how much you bid relative to everyone else. Raising your own listing only costs the difference.

### What can I list?
A product website or an X @handle. Chat invites, adult content, tracking links, and bare link shorteners are not allowed.

### Does Biddr use ads or an algorithm?
No. There are no ads on the board and no engagement algorithm. Rank is the bid.

### Who is Biddr for?
Founders, indie hackers, SaaS teams, AI tool builders, and creators who want paid, visible placement on a live leaderboard.
