In terms of measurement, I use google analytics (google tag manager) and the Amazon reports itself (content insight/content performance tells you what URL performed how and generated how many sales). Ad all of that date in a spreadsheet and create some formulas to summarize them. Simply described: google analytics "number of visitors", content performance "clicks" and "sales" (visitors vs. clicks = CTR, visitors vs sales = sales, clicks vs. ordered items = conversion)
