I have several ecommerce websites and would like to focus on the all around improvement of one in particular. I have recently noticed and increase in costs in adwords but conversions are decreasing.
I have almost 100,000 emails from past sales and do almost nothing with them. Many of them are from sales on marketplace which we will need to do a re opt in of some sort as they date back to 2003. Other I know are good from a box being checked on our website.
