In our e-commerce studies, we found that 20% of the overall task failures in the study — times when users failed to successfully complete a purchase when asked to do so — could be attributed to incomplete or unclear product information. Leaving shoppers' questions unanswered can derail a sale or even worse, make shoppers abandon not just the purchase, but the site as well. One shopper in a recent study could not find the information he needed in the product description, so he left the site to search Google for more product information. In the course of his search, he found another site with the same product, a more complete description, and a lower price.
