As mentioned above, an e-commerce site is not a good place to put AdSense. If that is what you are doing, you are sending potential customers to your competitors.
Unless you are in a niche with a high payout, you will need hundreds of articles and thousands of visitors per day to make $5 to $10 daily from AdSense. The real key is traffic. A smal percentage of visitors will click on the ads. Most will not. You need to be able to drive lots of free traffic to your site.
