I like that it is easy for me to use, but also very good at finding products from different eCommerce websites so you can compare them easily without having to switch between sites or have multiple tabs open in another browser window/tab. It was hard sometimes to get used to how to navigate through all the features available with Shop Rank. There are other similar apps out there (like Product Hunt) which provide more functionality than what we need as an online store owner. We realized our competition has better tools when searching their marketplaces because they were able to list hundreds if not thousands items per category while ours only lists about 10 - 20 total listings.
