E Commerce
An e-commerce site's product pages are that site's lifeblood. These are the pages that spotlight products and offer shoppers a 'Buy' button — they're a site's "payoff" pages.
Indeed, the primary struggle of every e-tailer is driving shoppers to their product pages, and then convincing those shoppers to commit to a purchase.
Step One: Simplicity
Because online merchants spend so much money driving shoppers to their product pages, they want to make sure to make a sale from these pages. Consequently, many e-tailers crowd their product pages with a plethora of items — they figure that if one item doesn't clinch the deal, then the item right next to it will.
But these crowded product pages are counterproductive. Simplicity is key in a product page, Nielsen says. "Simplicity in the sense that it's about one product, because when you have multiple products that's when you add complexity and it just becomes overwhelming." Focusing each product page on a single product has become the norm among successful online merchants.
Clarity, too, is important. "The main thing should be extremely clear, like 'what is this product?' Here's a picture of it, here's the price, and here's the shopping cart."
But there are exceptions, he notes. All of a single product's options should be offered on a single page. "There can be variants of a product, let's say, a shirt comes in multiple colors and sizes — I would view that as one product." But in the case of two truly different shirts, they are best placed on two different product pages.
In the case of items that are similar yet different — for example, various types of camera with different lenses — links to them should be displayed not on a product page but on a category page. (A category page is one level up from a product page, and it offers links to a broad array of products).
In this case, these similar cameras should be presented on the category page with short descriptions, such as: "Here's one for the professional photographer, here's one that's more point and shoot, here's a more feature-rich camera." The key point: each link on the category page should link to separate, individual product pages.
Product Page "Dimensional Navigation"
Imagine a shopper on your product page who has found almost exactly what they were looking for. However, they want just one more attribute. If the product had this one last feature, they'd plunk down their cash.
But that hypothetical shopper is stuck. Because, for example, the DVD player they're looking at longingly fits all the specs they want, except for one — but your product page doesn't show them how to navigate to find a DVD player that has that one additional feature.
The shopper "is typically lost in that situation, they have to go back up and visit all products," he says. "And that's awfully difficult for people to do." To solve this problem, Nielsen recommends what he refers to as "dimensional navigation." This navigation style enables the shopper to move from one product to the other according to highly specific criteria — often just one more thing.
Building a page with dimensional navigation means "product pages should actually be linked together," according to different dimensions or attributes that make sense to the customer.
In other words, "If you know from market analysis that there are certain criteria that people use to buy, build it into your navigation."
Product pages should be simple, but they shouldn't lack ready access to a complete source of information.
"Quite often people need to know some specifics to decide whether they want it or not," Nielsen says. "And this is one of the reasons people give up on buying, because they're uncertain about some of its attributes — like, 'Will it work with what I already have?'"
If you don't make it clear, "People aren't going to gamble and order it just in case it might work," he says.
Providing information, however, should be done with care. While a classic mistake is not giving enough information, "there's a dual problem of giving too complicated information." Dumping a load of product specs can create the "deer in the headlights" effect in your shoppers, which doesn't help sales.
The best strategy for providing information is layering. Layering is when all the information is available, yet it's one click away — but just one click. "It can't require another fishing expedition to go and find it — it's got to be a clear link that says 'technical specs' — you click that and then you get it."
That way, product information is readily available for those who want it, but won't confuse those who don't need it.
Expert Opinions
In some cases, presenting an array of expert opinions on the product page can be a seductive sales tool. However, e-tailer beware: expert reviews must be used cautiously.
"They problem is, can people trust them to be independent reviews, or do they feel like it's more and more sales information?" Nielsen says.
Shoppers, of course, often visit other sites for research prior to purchase; so placing expert opinions on your product page may be either redundant or actually distracting.
However, if a merchant has a truly accredited source to quote — a well-known publication or product guru — "That's a big credibility booster," Nielsen says. "It's not just you saying it, but there's actually someone else who's saying it as well." This is especially true if you can link to an external site that is clearly independent of yours.
