my adsense pay/click has been going down to about 0.3/click from about 1/click since about February, this site is for industry professionals only , so I am far from satisfy with this result. I decide to sell things related to this industry, and I have opened my first account on eBay. anyone can give me some suggestion on my current situation? thanks.
So what is the problem? If you are looking for suggestions to get more sales, you could set up a store also on your site for people to buy things, or put a "ticker" displaying your latest and greatest ebay items.
