I use it on my sports forum - You can target ads from certain categories and keywords, so it fits the theme of your websites..
The 1 day cookie is stupid, but if you place a bid in that day and win it 7 days later you still get credit for it. Also I think your 1 day cookie is overridden, if you click the EPN from a different site like Google.
If you know some heavy ebay shoppers that are friends they can generate $$ for you.
I was just curious if you were a member for a while before the changes and if you still use it? Have you noticed a huge downturn in your earnings?
The one day cookie is crazy, I know many times people get confused with ebay and paypal and think they need to move money into paypal before buying vs just paying via paypal and letting them automatically do an instant bank withdrawl. I know many times buyers think they need to wait for payments to clear into their paypal account before buying. I would venture to bet a good portion of sales get pushed back a day or two for this reason. Also how many people buy instantly many will add to watchlist and buy later or will buy the last day of an auction vs buying on day 2 and waiting 5 more days.
In my experience the more caveats and less transparent the payouts are means the affiliate company is trying to find any reason not to pay affilates. If it weren't for the one day cookie and lack of transparency in what we earn I would love the program as like you said you can do text links, you can link to specific products, you can link to search pages of products in your niche but that one day cookie just killls any chance of earnings imho. I was putting it up on everything and after seeing lots of impressions, a fair number of clicks, and no earnings I took it down off all my stuff
