Typical mistakes when developing an online store that cause businesses to lose sales

A modern online store for every business is an effective tool for sales, automation, and marketing. But sometimes companies face a problem when the store works, advertising campaigns are launched, visitors enter the catalog, yet the number of sales remains minimal.

The main reason lies not in the advertising campaign, not in a specific product, but in mistakes made at the stage of online store development. At the same time, such mistakes become noticeable only over time, when the website starts working. That is why it is worth considering common website structure mistakes and other equally relevant mistakes that lead to the loss of potential customers and money.

Mistake No. 1: Developing a “beautiful” website instead of a sales tool

One of the most common mistakes is focusing on attractive design while overlooking other important aspects.

Of course, visuals play a key role, but it is important not to forget the main tasks of an online store:

• building trust;
• helping the user quickly find the necessary product;
• encouraging online order placement;
• simplifying the purchase process.

When a user does not understand where to click, how to choose a product, or how to place an order, even a creative and stylish design will not be able to save conversion.

After all, eCommerce website development should be built around the buyer’s logic and behavioral scenarios.

Mistake No. 2: An overly complicated catalog structure

When creating an online store, business owners often want to place everything on the website at once, which leads to dozens of categories, confusing filters, an overloaded menu, and complex navigation. As a result, visitors get lost on the website because of too much information, close all pages, and move on to competitors.

In this case, the following rule applies: the simpler the customer’s path to making a purchase, the higher the probability of a successful product sale. This is especially relevant for stores with large catalogs and a diverse product range.

Today, the list of key success factors for an online store includes a well-thought-out catalog structure and high-quality UX.

Mistake No. 3: Slow loading of all pages

Every extra second that a potential customer has to spend on the website affects the number of sales. Modern users are not used to waiting; they want to make online purchases quickly at any time, which is especially relevant for impulse purchases.

Slow page loading can occur for the following common reasons:

• weak hosting;
• heavy images;
• overloaded animations;
• unoptimized code.

The website must open and load quickly on all devices, both desktop and mobile. Otherwise, the business loses not only customers but also Google rankings. Today, a fast online store is no longer an advantage — it is a mandatory standard that must be followed.

Mistake No. 4: Lack of a mobile version of the website

Adapting pages for mobile devices, such as smartphones and tablets, is one of the main conditions for achieving a large number of sales. Many visitors enter online stores from their smartphones, making online purchases in different places — at work, on vacation, or in transport.

Therefore, having only a desktop version leads to user inconvenience: when opening the website on a mobile device, the user sees small buttons, complex forms, and slow loading. Mobile UX directly affects conversion and advertising costs. If it is inconvenient for the user to shop from a smartphone, there is a high probability that they will close the website.

Mistake No. 5: Lack of integrations with CRM and accounting systems

Some companies refuse to keep up with the times, so most orders continue to be processed manually. For example, copying data and updating product stock. This leads to lost customer requests, errors in product availability on the website, and much more. As a result, chaos is created inside the business, which worsens customer service.

When creating a modern online store, it is impossible to do without mandatory integration with:

• payment services;
• warehouse systems;
• CRM;
• analytics;
• delivery services.

Automation helps save the entire team’s time and thereby contributes to sales scaling by eliminating constant “manual processes.”

Mistake No. 6: Poorly thought-out product cards

The main salesperson in any online store is the product card. That is why it is important to pay maximum attention to its design.

Among the most common mistakes in product card design, the following should be considered:

• an insufficient number of photos;
• lack of customer reviews;
• complex or weak product descriptions;
• lack of benefits;
• complicated buttons for making an online purchase.

The user should receive the maximum amount of information in just a few seconds while viewing the product card.

The probability of placing an order will depend on how few doubts the customer has.

Mistake No. 7: Lack of SEO at the development stage

Store owners often remember the need for SEO optimization only after launching their business. This leads to the website structure not being “prepared” for further promotion from the very beginning.

As a result, the following problems may arise:

• poor indexing;
• low rankings;
• duplicate pages;
• expensive advertising traffic.

SEO should be planned at the design stage of the future online store in order to take the following features into account:

• the future URL structure;
• optimal loading of all pages;
• availability of structured data;
• mobile adaptation;
• a well-thought-out structure of all pages.

All this is called an important foundation for obtaining stable organic traffic in the future.

Mistake No. 8: Lack of analytics and understanding of user behavior

Some owners make the mistake of evaluating the effectiveness of their business development solely by the number of orders.

In this case, analytics is essential, as it helps clarify the following questions:

• which pages are not working properly;
• which products actually bring good profit;
• at what stage users leave without making a purchase;
• why conversion is decreasing. 

The development of a modern online store should be based on obtained data and verified information, not on simple assumptions.

For example, to achieve real sales growth, it is necessary to make well-considered decisions suggested by properly configured analytics.

Mistake No. 9: Saving money on development

At the planning stage of creating an online store, the future owner must determine the budget. Often, the desire to do it “cheaper” wins, which leads to serious consequences:

• the need for constant improvements;
• numerous technical errors;
• limitations in website development for sales;
• excessively low loading speed;
• the need to completely rebuild the website after only one year of operation.

It is important to remember that an online store is not just endless expenses, but above all an investment in the development of one’s own business.

Therefore, from the very beginning, it is necessary to build a platform that will scale together with the company.

Mistake No. 10: A complicated checkout process

An overloaded checkout is another equally critical and common mistake.

Users may abandon an online purchase if they face:

• 5 or more steps;
• mandatory and complicated registration;
• filling out long forms;
• re-entering their data;
• long confirmation via phone number or email.

It is important to organize the online order placement process as quickly and simply as possible. It should be a purchase completed in just a few steps, with a minimum number of fields, autofill, and the ability to place a guest order without mandatory registration.

Remember that every extra user action reduces conversion.

Mistake No. 11: Lack of trust in the store

If the website causes doubts for the user, even the availability of high-quality products will not save the situation.

Potential buyers are most often concerned by the following: 

• outdated page design;
• lack of contacts for quick communication;
• lack of reviews from other customers;
• lack of information about the company;
• numerous errors on the website;
• lack of guarantees and return policy details.

The buyer should have the feeling that they are dealing with a real and reliable business. After all, the decision to make a purchase directly depends on trust.

What is truly important when developing an online store

What is a successful eCommerce project? It is the perfect combination of several factors and elements at once, among which the following deserve attention:

• SEO;
• analytics;
• marketing logic;
• convenient UX;
• optimal speed;
• automation;
• a well-thought-out structure.

Therefore, online store development is not just design + programming, but also a deep understanding of all business processes from the inside. Companies that managed to take all nuances into account at the development stage receive not a standard website, but a full-fledged tool for sales growth.

After launch, fixing all problems will be much more difficult and expensive. That is why it is important to consider in advance how exactly the website will work for the business, for customers, and for the future development of the entire company.

To effectively manage all website content, it is necessary to choose a high-quality CMS in advance. The article on the relevant topic will help with this: “How to choose a CMS for an online store: Shopify vs WordPress vs OpenCart and other options”.
