	%X An online advertisement system and its implementation
for the Yioop open source search engine are presented. This system
supports both selling advertisements and displaying them within
search results. The selling of advertisements is done using a system
to auction off daily impressions for keyword searches. This is an
open, ascending price auction system in which all accepted bids will
receive a fraction of the auctioned day’s impressions. New bids in
our system are required to be at least one half of the sum of all
previous bids ensuring the number of accepted bids is logarithmic
in the total ad spend on a keyword for a day. The mechanics of
creating an advertisement, attaching keywords to it, and adding it
to an advertisement inventory are described. The algorithm used to
go from accepted bids for a keyword to which ads are displayed at
search time is also presented. We discuss properties of our system
and compare it to existing auction systems and systems for selling
online advertisements.
