- In particular, the research provides insights on the content and features Vitamins & Supplements sites need to provide users to ensure they’re able to make a purchase decision
At Baymard our research team has just spent 1,800+ hours usability testing and researching Vitamins & Supplements website features, layouts, content, and designs — leading to our new study on Vitamins & Supplements UX.
The research is based on more than 230 qualitative user/site usability test sessions following the “Think Aloud” protocol (1:1 remote moderated testing).
This industry-specific research study focused on a total of 13 sites that distribute vitamin and supplement products in the US — with almost all test sites operating worldwide.
Our study included 11 multibrand Vitamins & Supplements sites: eVitamins, GNC, iHerb, Lucky Vitamin, PipingRock, Pure Formulas, Puritan’s Pride, Swanson Vitamins, Vitacost, Vitamin Shoppe, and Vitamin World.
In addition to multibrand sites, our research study included 2 single-brand, or white-label, sites: Nature Made and Nature’s Sunshine.
During testing the users encountered 1,000+ medium-to-severe usability issues.
These issues have subsequently been analyzed and distilled into the 490+ UX guidelines found within our Vitamins & Supplements research study (all of which are available as part of our Premium research findings).
The 490+ guidelines cover most aspects of the online exploration and purchasing of vitamins and supplements, at both a high level of general user behavior as well as at a more granular level of specific issues users are likely to encounter.
In this article we’ll introduce 3 high-level UX findings for Vitamins & Supplements sites:
- Detailed product data is critical to users’ purchasing decisions
- Vitamins & Supplements sites need several specific image types to provide users with the visual information they need
- Filtering performance is key to users’ ability to find suitable products
1) Detailed Product Data Is Critical to Users’ Purchasing Decisions
Unlike general e-commerce sites, where even highly technical products will often still have aesthetic considerations that must be highlighted on their product pages, users shopping for vitamins and supplements will often have very little concern for a supplement’s aesthetics and instead will be on the lookout for information about the supplement’s ingredient names, their amounts, and the supplement’s key benefits.
Even if the content included in the supplement description isn’t going to be the deciding factor for all users, they will inevitably rely on supplement descriptions to validate whether or not the supplement fulfills their unique combination of needs.
Indeed, our quantitative survey reveals that, out of 3,439 adult shoppers in the US, 36% consider “better product information online” as the most important reason to shop online (compared to shopping at physical stores).
Given how important product information is to users — especially users shopping for vitamins and supplements — online retailers should take care to make the supplement description information as thorough, trustworthy, and easy-to-find and -read as possible.
Yet some products during testing were missing the product description entirely — a surprising oversight given that users will likely simply reject out of hand any product that’s missing a description.
Furthermore, beyond the “e-commerce basic” of providing a product description, vitamins and supplement products need to be fully described; in particular, the key supplement ingredients, the amount of the ingredients, and any potential allergens the ingredient may contain (e.g., “Contains Tree Nuts”), as well as dietary information (e.g., “Vegan”).
Besides the obvious necessity for sufficient enough details in the supplement descriptions, our testing also revealed that users’ willingness to engage with and find answers in these areas is dependent on how the description is visually styled.
In particular, presenting all the critical vitamin and supplement info in an easy-to-scan format such as a “Supplement Ingredient Table”, which was observed to perform very well for participants during testing.
2) Vitamins & Supplements Sites Need to Provide Several Specific Image Types
At general e-commerce sites, product images have long been observed in our research to act as one of users’ primary methods for evaluating general products.
Without the ability to physically inspect a product (i.e., holding the item in their hands), product images offer an essential resource for users to gain a rich, visual understanding of a product.
For Vitamins & Supplements users, while the visual aesthetics of the products most often don’t matter, supplement images (e.g., packaging images, feature graphics, etc.) still provide a critical link for e-commerce shoppers to learn about highly technical supplement products.
In particular, images that provide the same function as the label on a physical bottle, as well as images that provide visual information on the real-life size of the supplement, were during testing observed to be important to users considering purchasing supplements.
Indeed, visually rich supplement images can provide users with a helpful informational safety net for verifying supplement information — or serve as a fallback if information is otherwise missing or hard to find elsewhere on the supplement details page.
While bespoke and quality imagery can be resource-intensive to produce, these images can be critical for users.
Consequently, any Vitamins & Supplements site should invest in these helpful user resources.
3) Filtering Performance Is Key to Users’ Ability to Find Suitable Products
Much like on general e-commerce sites, the ultimate purpose of the supplement list is to provide an effective pathway from product lists and search results to the all-important supplement details page — where many users’ final purchasing decisions will be made.
Indeed, users on Vitamins & Supplements sites will need many of the same visual considerations (e.g., page designs, text styling) that are important to high-performing product lists in general e-commerce.
However, without the right tools, finding just the right supplement can be an almost impossible task for the user.
Moreover, on sites with large supplement catalogs, users having access to plentiful (and effective) filtering options can transform an initially daunting supplement list into something much more manageable.
In particular, beyond the “basic” filter types, providing several industry-specific filter types — such as “Diet” (e.g., Vegan, Gluten free), “Allergens” (e.g., Soy, Dairy), “Format” (e.g., Tablet, Capsule, Liquid), and “End User” (e.g., “Women”, “Kids”) — is key to allowing users to narrow down extensive supplement lists (which may contain 1,000s of items) to something easier to navigate.
Additionally, filtering design considerations — such as promoting important filters, displaying “applied” filters in an overview, showing the number of matches for filter values, etc. — are as important to supplement lists as they are to users on general e-commerce sites.
Ensure Users Shopping for Vitamins and Supplements Are Able to Find Critical Supplement Information
Of the industry studies we’ve conducted, the issues Vitamins & Supplements participants encountered during testing perhaps bear the most resemblance to issues general e-commerce users face.
Therefore, in order to have a high-performing Vitamins & Supplements site, it’s crucial to ensure the site performs well across a wide range of UX considerations, from the Homepage, to Category Taxonomy, to Checkout, along with Product Details pages and Product Lists and Filtering.
Making sure the site performs well across the spectrum of e-commerce UX will set a solid foundation for user success, which can then be perfected by applying the Vitamins & Supplements–specific guidelines included in this new study.
