Here we have an example of a single advertising area being bid on by two Project Wonderful members, Alice and Partario.

And each of them have an ad they want people to see:

Alice's AdPartario's Ad

You can see how the Infinite Auction works as they vie for control of this advertising space! Click on the scenarios below, starting at the left.

  Alice's bidPartario's bidAd being displayed
Alice starts out and bids a maximum of $5 a day for a week. Since she's the only bidder, her bid starts out at $0. Free advertising!$0

Alice starts out and bids a maximum of $5 a day for a week. Since she's the only bidder, her bid starts out at $0. Free advertising!$0 
Partario wants in! He sees Alice's bid of $0 and decides he'll outbid her with a bid of $1 a day for one day. He places his bid, but Alice's bid automatically outbids him.$1.1$1
(outbid)
A day later, Partario's bid expires, and Alice's bid automatically drops back down to $0. Free advertising!$0

Alice starts out and bids a maximum of $5 a day a day for a week. Since she's the only bidder, her bid starts out at $0. Free advertising!$0 
Partario's back, and this time he decides to bid $100 a day for a week, with an expense limit of $1. Alice is outbid! Notice that Partario's bid goes only as high as it needs to in order to defeat Alice.$5
(outbid)
$5.1
Since Partario's bid is pretty big, but his expense limit is pretty small, the $1 expense limit is very quickly reached. His bid was charged at $5.10/day to a maximum of $1, so he got about five hours of display time ($5.10/day is about 20 cents an hour) before that $1 limit was reached.

His bid expires, and Alice's takes over again at $0. Free advertising!

Alice starts out and bids a maximum of $5 a day for a week. Since she's the only bidder, her bid starts out at $0. Free advertising!$0 
Partario's back, and this time he decides to bid $100 a day for a week, with an expense limit of $1. This is a bid that is almost certain to win, but with the expense limit, he knows he won't spend more than he wants. Alice is outbid! Notice that Partario's bid goes only as high as it needs to in order to defeat Alice.$5
(outbid)
$5.1
Partario also decides to place a second bid, this time of $1 a day for a week. This way, if his more expensive bid expires, he'll still have a chance of his ad being shown at a rate he likes! This new bid is outbid, but his older bid of $100 (max) is still the high bidder, so his ad is being shown.$5
(outbid)
$5.1
(plus another bid of $1 that's outbid)
Since Partario's bid is pretty big but his expense limit is pretty small, his expense limit is very quickly reached. His bid expires, and once again Alice is the high bidder. Partario's second bid of $1 a day forces Alice's bid up a bit.$1.1
$1
(outbid)
Finally, a week after she placed it, Alice's bid expiry date is reached, and it expires. Partario's bid of $1 a day is now the high bidder! Nobody else has bid, so: free advertising! $0

This is a simplified example: in most auctions there are dozens or hundreds of bids active at a time, which pushes advertising prices up to the market rate. We also allow publishers to set minimum bid, if they wish!

Note that in all situations, Alice and Partario are only charged for as long as their ad is being shown.
