During our large-scale usability research, the product page was often observed to be a pivotal point in the user journey.
Indeed, based on the information they found in the product description, some users would feel confident enough in a product’s suitability for them to decide to purchase.
On the other hand, the lack of sufficient product information would cause other users to abandon the page — sometimes, even, the site itself.
Furthermore, when sites did not provide desired information, we observed that some users would make incorrect assumptions about a product (which would sometimes result in frustration and unnecessary returns).
However, based on our most recent benchmark data, 10% of the largest e-commerce sites fail to have a consistently high level of detail for their product descriptions.
In this article, we’ll discuss
When desired information wasn’t available in overly brief product descriptions, some users during testing would quickly move on to consider another product — or would move on to a different site.
This is especially true when users encounter more than one insufficient description on the site, as some users will assume that the quality of descriptions they have already seen is representative of the overall quality of product information across the site.
Others spend a bit more time on the product page (1–3 minutes) scanning other sections of the product details page searching for this information.
Sometimes they find what they are looking for in, for example, the reviews, but overly brief product descriptions place too much strain on other page sections, which may or may not resolve the issue for users.
It’s important to remember that while a customer in a physical store can often consult with an employee about a product’s features, online shoppers are more restricted: even if the option to “chat” about the product is available, almost no users are likely to do so (as was observed in testing).
Therefore, the product description is sometimes all a user has when it comes to trying to find detailed information about a product.
If the description fails to meet users’ expectations, many will simply abandon, rather than take a chance on purchasing the product.
Testing made it clear that sites must provide sufficient information in product descriptions to give users enough to consider purchasing a product.
Yet what exactly should be provided differs, of course, from site to site and from product to product.
However, even though it would be impossible to anticipate every high-priority question a user may have about a product, addressing the needs of many users can be relatively straightforward for most product types.
Below are some examples of common information that users sought out in testing, but was sometimes not provided by sites.
Materials and Ingredients — or generally a product’s composition — were key product details that users sought out during testing.
This type of information could apply to the chemical composition of products in the health and beauty industry, such as makeup and skin care products, or to the textile and material composition of apparel, such as clothing items and athletic shoes.
When shopping for beauty products, for example, 50% of users in our desktop study required information regarding the ingredients. If such information was not readily available, users were quick to dismiss a product in favor of one with a more detailed product description.
Moreover, while many users just want to get an overview, some have specific concerns about particular ingredients — which might be based on allergies or other sensitivities.
Therefore, users also react positively to product information about what ingredients are explicitly not included. These intentional omissions could be potentially harmful chemicals — for example, being “BPA-free”.
Similarly, during testing users shopping for apparel repeatedly inquired after the material makeup of products they were interested in. Users’ interest in apparel materials most likely could be related to future care instructions — which are sometimes included in product descriptions as well.
For example, some users may be looking for technical benefits of the material itself — such as Gore-Tex being waterproof, or spandex being flexible. Other users may have material sensitivities or simply preferences for one material type over another.
Whatever the users’ needs happen to be, including material and ingredient information helped many users find suitable products and made their ultimate purchasing decisions easier.
Product dimensions were observed in testing to be important to most users looking for physical items. Many had questions or concerns which could be linked to a product’s measurements.
Whether it was external dimensions or the particular dimensions of a given feature, users were often swayed by the presence — or absence — of the product’s dimension and size details:
As we observed in testing, this extra level of detail can be a crucial differentiating factor between products.
Similarly, labeling dimensional values with their units of measure is essential.
However, as one user stated, “‘65 cm’. I don’t really know how that would compare with inches”. Therefore it may also be advisable to include a product’s dimensions in an alternate measurement system — for example, including Imperial units in parentheses alongside metric measurements.
Compatibility information will often be the most important product attribute for users investigating products with strict compatibility dependencies.
In some cases, a product’s relevance is determined entirely by its compatibility with another product the user already owns or plans on buying.
Some examples of compatibility-dependent products include the following:
If users are unable to find key compatibility information, or if the information is incomplete — such as listing a model series but not the explicit model number, or the information is not presented in a way users can understand — users will be forced to either conduct their own research off-site or abandon the product altogether.
Most importantly, very few users will feel confident in making a purchase for a compatibility-dependent product where there’s even the slightest doubt whether it will be compatible — simply, users’ desire and ability to “fill in the blanks” is virtually nonexistent for products with incomplete compatibility specs.
Since product images are so important in helping users find a suitable product, questions or concerns that arise from these images should be addressed in the product description.
Indeed, during testing users at times were intrigued by a feature depicted in a product image, and wanted to learn more about it — and would often look to the product description to fill in the gaps.
Even when supporting captions are provided for ambiguous images, the following image types are particularly likely to prompt users to seek answers in the product description.
Product images that include graphics meant to bring attention to features may be especially evocative — as shown in the above example with the water splashing on a speaker — but also potentially ambiguous, misleading, or otherwise hard to interpret for users.
Indeed, these images were consistently observed during testing to lead to additional questions from users.
Therefore, any graphics included for product images, which could be ambiguous or misinterpreted, should be further explained in the product description.
Users who already understood the graphic will have their understanding confirmed, while users who were uncertain will be able to fill in the gaps using the product description.
Similar to images that include graphics, icons are sometimes used to bring attention to specific facets of a product — which are often site-specific.
While the general idea behind these icons may be correctly inferred from context by some users, others users may misunderstand their actual meaning.
In either case, including a definition of an icon’s meaning in the product description is necessary to fully explain its nuances to the user.
Otherwise, users will have to hunt for this information elsewhere on the site — and where that information may be found won’t be obvious to users (if it’s explained at all).
Additional items featured in product images will lead many users to wonder if the pictured items are included in the purchase price, or whether they illustrate an available selection of optional accessories which are not included, or if the images are merely meant to show the product in a potential usage context.
In short: “Included Accessories” images, while important to provide, can be confusing, and therefore what is and what isn’t included should be described in the product description.
Note that having a caption (e.g., “Included Accessories” ) for “Included Accessories” images will be enough for some users. However, during testing some users skipped this information, and therefore having this information in the product description as well serves as a good fallback location for this crucial information.
Images can give users a better understanding of a product’s scale, but product descriptions can provide further, important details.
For example, as discussed above, dimension measurements are required to communicate exact product size specifications.
Yet some users’ eyes glaze over when reading “18 in x 22 in x 36 in”, but they respond much better to plain and accessible language that translates those measurements into something easier to grasp. For example, “fits in the palm of your hand” or “slides easily into your purse”.
As our desktop benchmark data shows, 90% of the top-60 e-commerce sites currently maintain a high level of quality and consistency in their product descriptions, making it the current industry standard — therefore, any deviations from that high-quality standard will be easily noticeable.
Moreover, when users do encounter poorly detailed product descriptions — violating the quality expectations they have, developed based on other e-commerce sites — this will likely lead to users experiencing frustration, delays in finding suitable products, and sometimes even site abandonment (either to conduct their own product research, or to visit a competitor site).
Therefore, to minimize these potential risks it is important to ensure a high level of quality and an extensive level of detail for product descriptions across the entire product catalogue.
Some information is likely to be sought by users considering specific product types, including
Additionally, product descriptions should support product images by explaining and contextualizing potentially confusing or ambiguous images.
Thorough product descriptions, provided consistently sitewide for all product types, will help to ensure users have enough information to make purchase decisions — while insufficient descriptions risk users concluding that a site “isn’t legit”, at which point they leave for a site that more robustly supports users’ information needs.
