Congratulations. What you need to do now is analyse why, if it's extra traffic then see where it came from and what keywords (if from a SE) they used. If it's a layout change rather than k/ws then take a couple of screen grabs and make notes of what works and try the layout (and some changes) on another website. If you don't have channels then set them up, and consider adding a URL channel for each page/section to see what is actually earning the money - you can use that data to improve your keyword targeting and add more pages to sections that are performing well. $5 is a good hump to beat, now keep at it!
