So, how were your e-sales this year? E-com usability

So, how were your e-sales this year? E-com usability may be easier to discuss in recent hindsight, after the dust has settled and the wishful thinking has stopped. How well did you do? What sort of ROI (return on investment) are you seeing?

E-commerce success can be measured in many ways; gross sales numbers are just a start. A more critical number in our view: Abandonment rates. How many people abandoned a shopping cart? Do you know exactly when and where it was abandoned? Most importantly - Do you know why someone abandoned a transaction?

The UK firm userfocus recently discussed "Nine tests for a usable checkout" which certainly merit a look. It's great to see another firm reiterate what we've been observing - and telling our clients - for years. "Ask the minimum number of questions. Use consistent and standard form controls. Place error messages next to the entries that need correcting." Truly commonsensical advice.

While the Nine Tests checklist is a great contribution, we still need to understand our users on a more specific level. The Amazon one-click book shopper is not the Playboy online club member, who is not the engineer joining IEEE online. Mental models, and the reasons for our purchases, play a role. The Amazon book shopper has learned to trust one-click ordering and needs little else. The Playboy user may like the added thrill of the chase that results from "teaser" screens. The engineer at IEEE will grumble if date entry fields don't enforce formats (he's an engineer!).

User experience is about seeing the world through the user's eyes, even if briefly. The personal interaction that comes from user involvement - be it as advisor to the design team, or simply as usability test subject - is irreplaceable. Feel-good aside, sincere understanding of - and concern for - your user is the key to successful business online.

You can and should know how many transactions were abandoned; that's tactical. Understanding that user and designing to his needs is strategic.

Coda: I was about to join an association I really admire last week. They lost me at unenforced date format for my date of birth. Why did they lose me? Because I know they're smarter than that.
