Online store design: filters, maps, shopping cart

As the catalog grows, it is the design of the online store that decides whether the customer will find the right product in two minutes or go to a competitor. Practice shows that the key value of UX/UI is fast search, transparent navigation, and frictionless checkout. According to the Baymard Institute (2024), it is imperfect filters and complex checkout that often undermine conversion. That’s why the focus on filters, interactive maps, and shopping carts is not about “pretty” but about profit and scalability.

Almost 59% of users abandon their shopping cart due to complicated checkout and insufficient filtering options.

According to Baymard Institute (2024)

🧭 Filters that work faster than search

Tiering and relevance

Large directories require multi-level filters. This directly correlates with search performance and reduces the number of clicks to a product. As advised by Nielsen Norman Group (2024):

For large ecommerce catalogs, use multi-level product filters to streamline search results.

Research by Nielsen Norman Group (2024)

In our web design practice, we build logic at the level of information architecture: we group characteristics, avoid duplication, add hints and “chips” of active filters. This approach combines website design and UI pattern performance without overloading the interface.

Setting up filters in WonderWeb

The WonderWeb team uses a structure where the user does not get lost among the options. This is backed by internal practices and ready-made components for quick integration. We adhere to the principle of “the main thing is close by” and put the key parameters on the first level.

Filters by category, brand, and feature help users find the right product faster.

According to WonderWeb – Website Design (2025)

When customized logic is required, we design it from scratch. This is appropriate for niche products with unique parameters. If you need a comprehensive implementation, use the website design service or order website development with business processes in mind.

Micro solutions for a big effect

A few details that systematically improve UX/UI design: auto-application of filters without reloading the page, saving the state when returning from the product card, visible parameter reset, clear “out of stock” states. These are the little things that shorten the path to the cart.

🗺️ Interactive maps and sales geography

Why do you need an interactive map in your store?

The user wants to control delivery and pickup. An interactive map gives a transparent answer to the question “Where to pick up and when?”. According to Statista (2024), the integration of interactive maps in 2024 increased the conversion of online stores by 12%. This is logical: less uncertainty means more decisions to buy.

WonderWeb’s approach to maps

We design a map as part of the purchase scenario. It’s not just a widget, but an integrated element that synchronizes with the shopping cart, the chosen delivery method, the warehouse, and the availability of goods at the point of delivery. It is important that the map works on mobile devices without lags and has a quick address search.

Data and performance

For maps, we limit the number of simultaneously drawn points, use marker clustering and lazy loading. This optimization maintains speed even with a large network of points of delivery. If necessary, we will connect map event analytics to the general stack.

🛒 Cart and checkout that do not interfere with the purchase

Scenarios that reduce bounce rates

The key goal of UX is to remove friction at every step. It is recommended to minimize the number of fields, add tips for delivery and payments, and support guest buying. It is important to keep the selected filters visible so that the user can quickly return to the list of products without losing context. On mobile, we use a fixed “Order summary” with a transparent cost.

Integrated modules from WonderWeb

We use proven UI patterns and connect them to business logic. As described in our materials:

We implement product filters, interactive maps, shopping cart functionality, and other modules for comfortable use of the online store.

According to WonderWeb – Website Development (2025)

This is combined with custom design and technical reliability. If you already have traffic and need conversion optimization, SEO promotion and hypothesis testing in conjunction with redesign will help. For peak campaigns, you should consider Google ADS and META ADS targeted ads to quickly test the effectiveness of changes in checkout.

Analytics and feedback

We set events for shopping cart steps, track bounces, and time delays. If we see that users are confused between delivery and payment, we simplify the options and highlight the most popular scenario. We make small releases, measure, and improve. This is how UX/UI design becomes a cycle, not a one-time project.

🧩 How to implement: process, risks, responsibility

Stages of work and approvals

We start with a catalog audit and a map of user scenarios. Then we create prototypes of filters, maps, and shopping carts. We conduct micro-interviews with managers to find out warehouse and logistics limitations. We approve the design and proceed to integration, not forgetting about regression tests on mobile devices.

Technical details that are often forgotten

• Performance: caching of filtering results, database indexes for characteristics, query optimization.
• Data: one attribute scheme in the catalog, consistent with filters and feeds of marketplaces.
• UI behavior: saving the state of filters when returning from the product card, readable empty states.
• Mobility: full-screen offscreen for filters, priority fields in checkout, system keyboards for input.

Why do you make multi-level filters for large catalogs?

Experts from Nielsen Norman Group (2024) recommend multi-level filters for large catalogs. This shortens the path to relevant results and reduces the number of clicks.

How do interactive maps affect in-store conversion?

According to Statista (2024), the integration of interactive maps in 2024 increased conversion by 12%. We embed the map in the purchase scenario and synchronize it with the shopping cart.

What modules do you integrate into your online store?

According to WonderWeb: “We implement product filters, interactive maps, shopping cart functionality, and other modules for comfortable use of the online store.” This is combined with custom UX/UI.

How to reduce cart abandonment if users are confused by checkout?

According to the Baymard Institute (2024), 59% of bounces are due to complex checkout and filters. We minimize fields, add a guest purchase, shipping and payment prompts, and track events in analytics.

At what stage do you check the performance of filters and maps?

After prototyping, we conduct integration and regression tests, especially on mobile. We optimize the database, cache filtering results, and apply marker clustering on the map.
