The importance of site artwork

With the growing quantity of online stores, the eCommerce landscape is becoming more competitive every day. To stand out, it’s crucial to create a website that attracts  & retains users with a well-structured platform. This platform should be an optimal blend of usability & security. The benefits of running an adequately developed & supported website include the following:

  • Increased Sales –  not only will local customers have access to your products and services online, but you will also significantly increase your reach and, with it, your profits. Nevertheless, just announcing your presence on the Internet is not enough; low-quality development, bugs, and outdated design can easily deter users from completing a purchase and returning to your store
  • Scalability – as the business itself grows its online presence needs to keep up. Timely & quality technical support, implementation of new features, and regular check-ups ensure the site doesn’t falter under increased traffic
  • Flexibility – online stores are not limited by time. Automation of the whole purchase process enables your customers to browse & make purchases at their convenience 24/7
  • Cost reduction – online stores eliminate the overhead costs associated with maintaining a physical store, reducing financial burdens & expenses
  • Data Acquisition – websites allow you to collect valuable data from your customers. It can be further processed & analyzed to enhance service quality & tailor both customer experience & your offer 

However, to get the abovementioned benefits, you must also know what settings, features, and architectural elements are crucial for an efficient webpage. Let’s get to them now.

Best practices for website architecture 

There are three primary choices for eCommerce website architecture. Each has its unique features & benefits so website architecture best practices are basically the correct choice of the one that works best for you.

Two-Tiered Architecture

This website architecture involves two business components: the client & the server. It’s ideal for startups due to its simplicity & cost-effectiveness.  Both sides of the architecture run web applications, business logic, and client application. Typically, the client application runs on the client side, collects data, and passes it to the database server so the two sides communicate. 


This architecture is very similar to the previous one, except it adds a business layer to the existing two-tier model. This allows a more customer-centric approach.

  • The client interacts with the website using the external user interface in the presentation layer. At this time, the application collects client data and passes it to the server side
  • Business layer -this layer is in the center; it uses a particular set of business rules by which it can delete, add and modify data content. So it sets up a more customer-centric approach to the site by collecting user preference data and selecting recommendations that are similar to the products you’ve already reviewed, and that’s not all it does
  • The data layer is used to store data and process queries. It is often found that this information is stored using relational database management systems

Each of them works as a separate module, having a different server. 

E-Commerce microservices architecture 

This emerging trend leverages independent components within a single system to provide improved interactions and a multichannel user experience. Although this E-commerce microservice requires complex maintenance, it’s highly scalable & flexible which is a great benefit for further development.

Quality website architecture design offers numerous benefits, including improved user interface, SEO (and thus the improved ranking), easy third-party integration & scalability, and enhanced site security.

Electronic commerce site protection – keep your customers secure

Another critical issue in creating an e-commerce website is its security. eCommerce businesses collect & handle sensitive customer data, making robust security measures absolutely essential. Let’s highlight best practices for keeping your online store secure:

  • Password Manager – when registering on your site, customers must come up with a password, and the best thing you can do is to implement a password manager in your system, which will offer unique complex passwords for each client
  • Multi-level authentication – to log in, use not only a username and password but also a one-time code
  • Content Delivery Network – this security tool protects your site from distribution attacks, which flood your area with traffic from several sources at the same time and make it inaccessible to users, allowing for data leakage
  • Firewall – a firewall monitors and blocks suspicious traffic to the site. They are unique to each company because you can define your own rules to detect suspicious traffic
  • Secure payment process – use only trusted payment providers and systems to securely store your customers’ credit card and other financial information, such as data encryption. It’s best not to store customer financial information on company servers
  • Install a secure socket layer certificate (SSL) – SSL scrambles and secures the customer’s credit data as it flows between their unit and the payment processor. SSL is the security standard for all e-commerce sites, and if you don’t use it, users can see it and leave the site instantly 

Top Tips for eCommerce Website Usability 

Usability is crucial for the success of an online store. Focus on the following features to improve the user experience of your customers: 


Ensuring readability is responsible for a user’s ability to perceive and digest information. If something is wrong with your site, it will immediately affect traffic. To improve readability, you should provide enough space between the elements, equally formatted paragraphs, and the presence of bulleted lists.

Simplifying navigation 

Navigation is an essential part of any website, especially for the sales segment, because thanks to navigation, you move around the site, search and purchase. No one likes to take too long to figure out how a site works, and the checkout process should be as simple as possible because customers don’t have a lot of patience. Implementing intelligent search and filtering is essential to find the product you want in one click. 

Create a visual hierarchy

Users have an impression of your site in less than 3 seconds; during that time, they can either wholly leave or stay. Your site should have a harmonious design, so the client can gradually learn your store and not scatter their attention to the different elements simultaneously; that’s why you need a visual hierarchy. Make sure to focus on your site’s main aspects, such as the catalogue and shopping cart buttons. The best experts in this are IT service companies because they know precisely how to make your site attractive. Centum-D supports its clients throughout the entire e-commerce site development process and handles everything from the site’s skeleton to design and post-launch support. 

Continue with simplicity in design 

For a long time, simplicity and minimalism have been leading design trends that apply to website design. Users are also accustomed to the idea and, therefore, can intuitively anticipate where you have this or that information, such as contact information, often at the bottom of the screen. A search box in the header of the site. It is also essential to use harmonious colors, so they do not cut the eye. But this does not mean your site will merge with the rest because you can use different animation, feedback, and fonts, and most importantly, all know the measure. 

Optimize the site speed

If your site is too slow to load information, you risk losing many potential customers and therefore need to monitor this very carefully. The most optimal loading time for the user is no more than three seconds; if more negatively affects the user experience, it is frustrating, and as a result, users leave the page.

Adaptation for mobile devices 

Today, the most frequent gadget for accessing the Internet is the cell phone, and therefore your website should be optimized for mobile devices. Your site should adapt to different screen extensions and have features useful to smartphone users, such as scroll buttons, sticky navigation bars, pinch-and-zoom for product photos, etc. 

In conclusion, creating a successful eCommerce website involves attention to detail, understanding current & predicting future user preferences, and staying ahead of global trends & best practices. Balancing security, usability, and a positive UE is the actual key to a thriving eCommerce site.
