During a research on shopping cart conversion rates I did the last couple of weeks, I found websites with 0,4% funnel conversion rates and others with completion rates up to 70%. I never expected to find such big discrepancies; no analysis can be made in such conditions so I started to look up reasons for these discrepancies.
After talking to different software vendors about various issues their potential customers reported and after noticing different trends in multiple analytics data, I found the fugitive criminal guilty for many many abandons in shopping carts: Shopper Trust.
Shopper Trust Wanted. Reward Offered.
How to find it? Easy, or so they say. Check out the following clues.
1. Among Trust’s best friends there’s a guy named “Price”

Showing prices & discounts next to buy buttons
It’s important for your users to pay the “right” price for your products, but more important is to really know how much a product costs. You might say this is obvious (I for sure would have said that), but going from one website to another I found many where it was unclear how much a product costs.
It’s not mandatory to have the price on the right or on the left of the screen. The important thing is that when the user says to himself “I wonder how much this software costs. I’d like to buy it”, he should get the answer before he gets to finish his sentence.
My 2 cents is to always have the price next to the buy button or link. This way you make sure that every time a user gets in the shopping cart he already knows the price of your product. Also, place it next to the product box, something very similar to the offline world where the user is used to always have the price next to the product he is buying.
