A Review of Ecommerce Usability & Design by Jens Schriver

Hi Steven,

Again a good base to build upon. I think the main challenge is to help the user understand where he is and what he's looking at, and do it fast. Disclaimer: I'm not into car tuning, so perhaps I'm missing something that's obvious to your

It took me some 30 seconds to understand what this page is about. At first I thought it was selling computer parts (because of the look and the photo of the electronics part). There's no photo of a car or engine to visually help me understand the product. The "free waterproof sleeve" makes me even more confused. What's this sleeve for?

It seems like you are primarily selling one, main product. Is that correct? What's the name of the product? I think that I would make the homepage very focused on selling the diesel tuning system. Maybe get inspired by iphone app sites. You'd have one, clear call-to-action: get people to the product description page.

The digital microprocessor part is actually pretty cool - I can see why/how this could help boost sales. But the image isn't well integrated, it doesn't help sell. How does knowing that there's a digital microprocessor in your gadget add value to the product? Spell it out to the visitor.

In general on this page, think about where you want the visitor to click. What do you want him to do? As a visitor I would feel the need for a bit more guidance.

You are right that there is very little text. The text that's there looks like it's hardcoded on the image. From an SEO perspective this is a big problem, but from a sales/usability perspective the page is not bad. I'd add a text section which:

• tells the visitor where he is
• what you offer
• why he should care
• tell him what he should do next (or show it with a CTA)

The visa image in the footer is good. Do you have any more credibility indicators that you could add? Is your company certified in some way? Do you (or whoever's the owner) personally have a relevant certification? Your product improves energy consumption - is there some sort of green seal you could use?

The phone number in the header is good. Shows we are dealing with a "real" business with humans behind it. Consider putting the address in the footer for the same reason.

I'm guessing your target market is younger men who want their car to go faster. Probably these guys are feature driven - for this reason your percentages ("35% more power" etc.) work well. But think about how to take this further. Do you have a case study about a car which was boosted from X horsepower to XXX horsepower? Maybe have a little "featured client" photo, with a happy guy with beefed up car and a big number like "40% increase in horsepower". Preferably with a nice quote about how much the guy loves your product.

Small detail: in the header it says "Log in or register". I'd leave out the "or register" part. Let them find out later (but ideally they shouldn't be forced to register at all!).

I hope that was helpful.

Kind regards, Jens
