If anything, quick view helps save user bandwidth and time. It becomes very cumbersome for the user to goto the product page only to find out that the product is not something that they like. So, quick view might decrease the page views or click rate but not conversion rates.
What affects ecommerce conversion rate?
Your value proposition, or Unique Selling Proposition (USP), is the single most important factor in your conversion rate. If you have a fantastic, unique product that fulfills a need for your customers, your site visitors will tolerate a lot of other imperfections in the experience in order to get it.
What is quick view used for?
Quick View is a file viewer in Windows 95, Windows 98 and Windows NT 4.0 operating systems. The viewer can be used to view practically any file. The software has been ported by third parties to support XP, Vista and 7.
