These last 5-6 days my sales have been falling a bit and I wanted to know what products where selling less and from which sources. Luckily, a few months ago I programmed my sales administration page to show a visual graphic of my sales of the last month, last year, and last 5 years. I decided to use the same code to make graphics both for each product I sell and for each source of sales (such as those that come from eBay or affiliates). These new graphics I added allowed me to pinpoint that the sales that are falling are the ones made directly on my site and for one specific product, and the fall started just as I made an update to that page, so I know my new page is doing bad and will update it again. Before I wouldn't have known where the drop specifically came from making it hard to know what I need to fix. This is really gonna help experiment and boost my sales as I can do a test for a week like a different price and visually see on the graphs clearly if the change is increasing or decreasing sales.
