  • Key points of website navigation (catalog, shopping cart, etc.) are available to the user at any moment, on any page of the online store.
  • The design of the key points of the user path (registration, purchase, subscription, etc.) is clear and simple.
  • The user has access to important information from any page of the online store.
  • There are no dead-end pages on the site.
  • That is, on any page the user can follow the link to another page. For example, all the articles in the blog are counter-linked, in the descriptions of services and products there is a CTA for placing an order, the 404 page contains links to the main website sections or search, etc.
  • The “Back” button of the browser is not blocked by the site.

Main menu (the next step of our UX audit checklist)

  • The main menu of the online store should be all in one place (except for checkout) and the user should have access to it from any page of the site.
  • All the menu items are sorted by priority and significance, from most to least important (left to right, up and down).
  • The main menu should not contain more than two subcategories, and the subcategories should differ from the rest of the menu items.

Structure of the website pages

  • The online store header should be concise and contain important information and links (logo, name, contacts, menu).
The header of the online store of kids’ products Pampik
The header of the online store of kids’ products Pampik contains intuitive navigation with the icons that are easy to understand and are performed in the same style with the store theme, the logo (“Ma and Pa’s helper”), the link bar. From the first seconds the user understands that this is a site for moms and kids.
 
  • The eye should be able to embrace every block on the page.
  • If the element is clickable, it should be visually clear and obvious. Once the mouse cursor is pointed at it, it should change.
  • The design of the icons and graphic elements should communicate their meaning and purpose and be intuitive.

Site search and product list page

  • The search bar, its size and design should be in line with the business objectives.
  • The search bar should be visible and available on any screen.
  • There should be only one search bar on the page.
  • There should be autofill and relevant prompts.
  • Prompts should be displayed in the search box according to the priorities and selection parameters (category-subcategory-products/content).
  • Search should minimize errors and false queries, look for synonyms.
  • If the query is entered from a wrong layout, the search box should automatically replace the search query.

Search results page

  • The search result matches the search query.
  • There is a possibility to filter the products.
  • In case no results have been found for the search query, a prompt appears as to how the search query can be edited or an alternative product is offered.
  • The quantity of the products found for the search query is displayed.
  • In case there is no possibility to search for the product by categories, the search throughout the whole site is conducted.

Text and its design on the website

  • Text should only provide the information that is useful for the user, without the fluff. First comes the most important information, then the rest.
  • The text is well structured –– headings, subheadings, paragraphs, quotations, different types of lists are used.
  • Texts are readable and easy-to-understand, not more than 75 characters in length.

Paragraphs

  • Ideally, the font size of the main text should be 16 px.
  • The text should be left-aligned.
  • The line length should not exceed 80 characters. If the lines are too short or too long, it negatively affects the perception of the text.

Headings

  • Headings give the user an idea of “what will follow”, or, which is even better, “what the text is about”.
  • The design of the headings should resemble the design of “their” paragraphs.
  • The size of the font for headings should be 1.5 times bigger than that for subheadings, and the size of the font for subheadings should be, in its turn, 1.5 bigger than that of the text.

Style, size and color of the font

  • The use of the uppercase should be justified and kept to a minimum, as it makes it difficult to read and perceive the text.
  • Fonts should be the same for all the website pages. They should be readable and contrasting against the background.
  • The color of the main text and that of the links should be different and contrast with each other.
  • The use of different text colors should be justified.
  • All long numbers should be separated by spaces for ease of reading (for example, 1 524 733).

Design of links and buttons

  • The text of the link should tell the user where it will take him/her.
  • The color and style of the links should be visually different from the rest of the text (underlined or highlighted).
  • If the user clicks on a link, it changes its color.
  • All the links that do not lead the user to another page have a dotted line underneath them.
  • The link text is long enough for the user to be able to comfortably click on it.
  • The links for downloading files should be visually different from those that take users to other pages of the site.

CTA buttons and links

  • Buttons are used to perform certain actions.
  • The website buttons should actually look like ones: by their shape, reaction to cursor and hover.
  • There is only one CTA button on the page, and it visually stands out among other buttons.

Anti-example:

The page is overloaded with information, there are two many catchy buttons, which misleads the user
Were you able to find the main CTA button quickly? The page is overloaded with information, there are two many catchy buttons, which misleads the user.
 

In the Mon Amie online makeup store there are also several CTA buttons, but they are designed in such a way that there is only one visual accent –– BUY NOW.

Only the BUY NOW button is visually accentuated.
 
  • The call to action or the text on the button is an imperative verb: Find, Buy Now, Subscribe, etc.
  • The button reacts to the cursor –– for example, changes the color to encourage the user to make a click.
  • In case some action is unavailable, buttons and links do not disappear from the screen, but are deactivated and blocked.

Forms to fill in  (the next step of our UX audit checklist)

How to design forms in general

  • Forms should be as simple and concise as possible. If it is checkout, registration, or any target form, it should contain only the mandatory fields.
  • If the field is optional, it should be reasoned and justified.
  • If it is a big form with many fields, it should be well-structured, the fields being grouped by their meaning, with subheadings for each group.
  • When you open the form, the cursor automatically moves to the first field.
  • The active field is visually highlighted.
  • The prompt stays in place when the focus is moved to the field.
  • If the form consists of several steps, there should be a step-by-step instruction and a progress bar. The user should be informed of the step he/she is in, and how many more steps there are left.
  • All the filled-in fields are saved until the process is completed so that the user does not have to re-enter the data in case he/she accidentally leaves the form page.
  • The user can move the cursor from field to field using the tab key.

Form elements – fields and their meanings

  • The name of the “Submit” button should correspond to the purpose of filling in the form (e.g. “Register” or “Proceed to payment”, etc.).
  • There are prompts, examples, or clarifications for the fields that the user might have questions about.
  • All the required fields are marked or highlighted and are visually different from the optional ones.
  • The names of the fields should correspond to their meaning and purpose.
  • Some fields are filled in by default with the most likely values. For example, for booking there are usually 2 adults entered in the search box by default.
  • Field labels should be performed in the same style.

Validation, mistakes, and prompts

  • There should be a possibility to take one step back so that the user could edit the already entered data.
  • Validation of the information should be carried out immediately after the focus switch and without the form page reloading.
  • If the user has made a mistake, the error message should appear near the field where the mistake was made. This message should be as informative as possible, indicating what exactly the problem is.
  • If the filled-in form has not been validated, the fields should still stay filled in.

Catalog and its features

Filters on the product list page

  • The user can deselect the selected values for lists and radio buttons.
  • Dependent fields should be updated synchronously.
  • It should be obvious, in what order, by what field and parameter sorting has been applied in this case.
  • It is intuitively understandable how one can change the sorting order or field.
  • The filter button is always visible to the user.
  • There are breadcrumbs by which the user can return to the filtered product list after opening the product card.
  • All the parameters are displayed in the filter as a list, and the user can reset any parameter.
  • If the filter has complex parameters, there must be a prompt explaining them so that the user could understand how and what they can be used for.
Example of the catalog filters for the Makeup online store

Sending a filtered list 

The user can send a link to the filtered catalog to another user, the latter being able to see the filtered items once he/she clicks on the link. 

Therefore, when conducting a usability audit of the site, it is important to pay attention to the following requirements:

  • When filtering parameters are applied, the URL should dynamically change.
  • The filtered product list should open without redirects, filter flashes, or additional transitions, even when you open the link in incognito mode.
  • All the changes of each filter field are saved.
  • All the filter fields affect the filtered list correctly, both when it comes to each particular field, and to field combinations.
  • After the filter is reset, the product list is rebuilt, and both the filter parameters and the URL are reset.

Adding a product to the cart from the catalog

  • The user can add any product to the cart.
In the George online store the user can add a product to the cart or to “Favorites” right from the product list page
In the George online store the user can add a product to the cart or to “Favorites” right from the product list page.
  • Once the item is added from the catalog to the shopping cart, there is a visual confirmation thereof.   

Number of items 

  • When the customer adds a product to the cart from the catalog page, the selected number of items should be taken into account.
  • It is better if the information about the available quantity of goods in stock is displayed in the field.
  • When the user adds items to the shopping cart or removes them from there, the number of items is automatically updated.

Mini-cart

  • When the items are deleted, new items are added, or the number of the already added items is changed, recalculation of the total amount and number of items takes place in the shopping cart block automatically, without page reload.

Product card

  • The heading contains the name of the product.
  • All the information about the product is up to date and displayed correctly.
  • There is a link to go back to the catalog, or breadcrumbs.
Example of breadcrumbs in the George product catalog

Adding a product to the cart

  • The user can add the necessary quantity of the product to the shopping cart.
  • There is a visual confirmation of the addition of the product to the cart.

Displaying additional blocks

  • If there are such upsell and cross-sell blocks as “Customers who bought this item also bought”, “Recommended products”, “You also viewed”, relevant products are displayed there.

For example, in the Dicentra.ua online flower store the cross-sell block is presented on the home page and offers promotional bundles: flowers plus a gift (“Cheaper together”).

In the Dicentra.ua online flower store the cross-sell block is presented on the home page and offers promotional bundles: flowers plus a gift (“Cheaper together”)  

In the product card there are various options of cross-sell and upsell tools, from sweets and cakes to similar and viewed products.

  • All the information about the product is provided (characteristics, reviews, configuration, etc.), links to it are displayed on the current page, but they do not take the user away from the purchase.
  • There are several high-quality product photos with a zoom option, so that the user could have a close look at the product before making a purchase.
  • If the product has additional parameters, the user can choose one of them right in the product card.

Example of the product card on the Mon Amie website

Shopping cart  (the next step of our UX audit checklist)

  • The total order amount shown in the shopping cart should be calculated automatically, taking into account all the discounts, promotions, coupons, shipping costs, or any other fees involved.
  • If incorrect data is entered, a warning/error message appears and the values are reset.
  • If the user enters a number or changes the value in the «Quantity» field, the total order amount is immediately recalculated. If a zero has been entered, the entry is removed. In this case, confirmation of the action is desirable to avoid random input.

Checkout page in the Pampik online store 
Example of the shopping cart in the online store of children’s products Pampik 

  • There is a button or a link to go back to the catalog.
  • When the CTA button is clicked upon, the user is taken to checkout or the next step of the order placement procedure.
  • If there is a mini-cart, all the data is synchronized with the main cart.

Checkout

  • The checkout page design should be laconic and contain the following elements: a logo leading to the home page, simple header and footer. This is to ensure that the user has fewer exit points from the checkout page.
  • At the checkout the user sees separate lines with the product price, the shipping cost, etc.

Example of checkout on the 966.ua website

  • The shipping costs are calculated automatically depending on the shipping method chosen, and the total order amount changes accordingly.
  • If delivery addresses are saved for registered users, they should be able to select the saved address or add a new one. If the user chooses to add a new address, the address fields should be automatically cleared.
  • The user is provided with up-to-date information about delivery methods and payment options.
  • For registered users all the checkout data is automatically saved and autofilled.
  • After the order is placed, an email with the order information and a link to the order history is automatically sent to the indicated address.
  • New users are automatically registered once the order is placed.

  • If there is an option of receiving and printing out a receipt, there should be a link to it here.

Personal account

  • During the registration all the user data is saved and used for subsequent orders (name, preferred shipment and payment methods, etc.)
  • There is real-time order tracking.
  • Orders can be paid for from the personal account.
