1) AuctionAds is not contextual, so content doesn't matter. Only keywords you enter.
2) They have a caching issue where you may have to reload the page to get up to date items, if you have not had a visitor within, say, an hour or so, otherwise they send ipod/handbags/purfume/etc ads...
Yes, the site needs more content!
I did use the nasa rss feed, replacing the story urls with my url (they can get the story there too!), so maybe some rss traffic will come my way. Need to find out why it is not updating correctly though...
I am getting spidered though! (only a few clicks otherwise)
