How to sell online for a suc­cess­ful internet business

The e-commerce market is growing, and there’s no end in sight. If you want to build an online business yourself and learn how to sell online, you should consider selling physical products. Selling products online is re­l­at­ively easy, and you can get started in a man­age­able timeframe and without a large in­vest­ment.

Is e-commerce right for you? The pros and cons

Some people who sell products online discover a true passion and turn it into their dream job. Others start their e-commerce journey with high ex­pect­a­tions, only to realise after a few months that running an online business—even if it is fin­an­cially suc­cess­ful—does not fully meet their personal ex­pect­a­tions. That’s why it’s important to be clear from the outset about the ad­vant­ages and chal­lenges you may face when selling products online.

In recent years, rising ad­vert­ising costs on platforms like Meta Ads and Google Ads have posed new chal­lenges for many online store owners. At the same time, AI tools such as product feed op­tim­isers, AI image gen­er­at­ors, and chatbots are unlocking new op­por­tun­it­ies for working more ef­fi­ciently.

Step 1: Market research and product selection

Market research is one of the most important found­a­tions for anyone who wants to un­der­stand how to sell products online suc­cess­fully. The choice of products and markets sig­ni­fic­antly de­term­ines future success. Selling products online works par­tic­u­larly well when there is suf­fi­cient demand.

Use current analysis tools like Google Trends, TikTok Creative Center, Amazon Best Seller Rankings, or tool suites like Sistrix and Helium 10 to real­ist­ic­ally assess product searches and demand. Social media platforms like TikTok or Instagram can es­pe­cially signal trends early, which you can leverage for your product.

If you come across online shops offering the same or similar products to the ones you’re planning to sell, that’s usually a good sign. A certain level of com­pet­i­tion suggests you’ve iden­ti­fied a viable and po­ten­tially prof­it­able market niche. However, if com­pet­i­tion is too intense, it may be wise to reassess your idea.

When choosing your products, also factor in the potential profit margin. Strong demand alone isn’t enough—if the market doesn’t allow for sus­tain­able pricing, turning a profit will be chal­len­ging.

To stand out against existing com­pet­i­tion, it is advisable to find a small niche of products. Here are a few examples:

• instead of ‘ac­cessor­ies’ → patterned socks
• instead of ‘tea’ → ex­clus­ively white tea
• instead of ‘fitness products’ → mobility bands or yoga cork blocks

Step 2: Create a business plan

Many online shop founders are tempted to skip this step, es­pe­cially if they don’t plan to seek investors or apply for a bank loan. Even so, it’s worth taking the time to create a business plan for your online shop. In the UK, a business plan serves as a practical roadmap for building and managing your business. It helps you think through key aspects such as your business model, target market, pricing strategy, costs, and expected revenue.

Writing your plan also makes it easier to identify weak­nesses and gaps early on, as well as to clearly define your strengths before you invest sig­ni­fic­ant time and money. A well-struc­tured business plan brings clarity to your com­pet­it­ive position, product offering, financial planning, and marketing strategy — all of which are essential for sus­tain­able growth.

A business plan is par­tic­u­larly important if you want to apply for financing. UK lenders and al­tern­at­ive finance providers typically expect a detailed plan because it shows you un­der­stand your market and have a realistic strategy for gen­er­at­ing revenue and managing risk. Gov­ern­ment-backed loan schemes such as the Start Up Loans programme often provide mentoring and support to help you develop your plan and access finance for your business.

Finally, while grants for startups in the UK are often com­pet­it­ive and sector-specific, most funding bodies will want to see a business plan as part of the ap­plic­a­tion process. A clear and thought­ful plan also gives ac­count­ants, startup advisers, or mentors a full overview of your project, enabling them to provide more targeted and valuable guidance.

Step 3: Choose a sales platform and set up your shop

In your business plan, you should already define which sales platform you want to use for your products. When selling products online, you can choose from a variety of different sales models. Choosing the right sales platform is a key decision when learning how to sell products online, as it directly affects reach, costs, and scalab­il­ity.

Social selling

The quickest way to set up is an online shop that operates through social media. Here, you sell directly through a profile on Instagram, Facebook, or Pinterest—no need for your own website. Since 2023, TikTok and Instagram have enhanced shop features, allowing sales to take place directly within the platforms. Utilise these features if your target audience includes younger buyers who are already shopping on these platforms.

Own online shop or blog

Running your own website gives you greater flex­ib­il­ity in how you sell and promote your products. You can design your shop exactly the way you want and use a wide range of marketing channels beyond social media.

Thanks to modern website builders, the technical barrier to launching your own online shop is re­l­at­ively low. Online shop builders cover all essential e-commerce functions, and hosting can usually be added directly. This keeps website man­age­ment and technical support in one place, making setup and ongoing main­ten­ance much easier.

If you have basic IT know-how and want to customise your shop in­di­vidu­ally, you can also use the CMS WordPress in com­bin­a­tion with the Woo­Com­merce plugin to ef­fort­lessly establish a pro­fes­sion­al online shop. You’ll need to handle hosting and domain re­gis­tra­tion yourself in this case. If you prefer not to manage main­ten­ance and hosting, it makes sense to book a complete WordPress solution with Woo­Com­merce or Managed WordPress, including hosting.

Online mar­ket­places

A third way to sell your own products online is through online sales platforms like Amazon, eBay, or Alibaba, also known as online mar­ket­places. The advantage here is that you don’t have to go through the effort of at­tract­ing customers to your shop, as you benefit from the traffic of the re­spect­ive platform. The downside is that you must pay a com­mis­sion and are limited in how you design your shop page.

Quick com­par­is­on of sales platforms

There are several ways to sell products online, and each option comes with its own ad­vant­ages and dis­ad­vant­ages. Social selling solutions allow you to showcase and sell products quickly and with minimal setup, but they offer limited access to full shop features, such as advanced shipping and logistics options. A dedicated online shop, by contrast, requires more time and in­vest­ment, but gives you access to a wide range of powerful features that support long-term growth and scalab­il­ity.

Besides the sales platform, you also need to consider shipping logistics and payment methods. There are various options available for these as well.

Shipping and payment method

As a store owner, you are usually re­spons­ible for shipping your goods unless you use drop­ship­ping, which means you do not maintain your own inventory but instead have your products stored and shipped by third parties.

Many shipping providers now offer eco-friendly delivery options. These are not only good for brand image but are also becoming in­creas­ingly important for en­vir­on­ment­ally conscious customers. Such ‘green shipping methods’ can create a real com­pet­it­ive advantage, es­pe­cially among younger audiences who place greater value on re­spons­ible con­sump­tion.

When selecting payment options for your online shop in the UK, you should also consider mobile payments and Buy Now, Pay Later (BNPL) services, as these are in­creas­ingly popular and can improve the checkout ex­per­i­ence for customers. Digital wallets like Apple Pay, Google Pay, PayPal, and others are widely used, with more than half of UK adults now regularly using mobile wallet services for purchases both online and in person.

At the same time, BNPL services such as Klarna, Clearpay, Zilch, and similar flexible payment options are es­tab­lished in the UK market and are par­tic­u­larly popular with younger buyers who want more payment flex­ib­il­ity at checkout. These options allow customers to spread the cost of a purchase in interest-free in­stal­ments, making them appealing for higher-value orders.

Offering a mix of modern payment methods alongside tra­di­tion­al card and bank transfer options means you’re more likely to meet the pref­er­ences of a broad range of customers — from tech-savvy younger shoppers to more tra­di­tion­al buyers who still pri­or­it­ise familiar payment methods.

Logistics via shipping providers

If you handle the storage and shipping of products yourself, you must choose one or more shipping providers. Inquire with providers about special rates and reg­u­la­tions for online retailers. Some offer special terms.

Instead of filling out labels manually, use online shipping systems. Ideally, integrate these with your online store through an interface. This way, customer addresses are read directly by the shipping tool. Ad­di­tion­ally, the tools allow you to track shipments and initiate pickup requests.

Part­ner­ship with ful­fil­ment providers

If you prefer not to handle shipping yourself, you can work with a ful­fil­ment provider. You send your products to the provider’s warehouse, and by in­teg­rat­ing a ful­fil­ment ap­plic­a­tion into your shop, each sale is auto­mat­ic­ally passed on to them. The provider then takes care of picking, packing, and shipping the order on your behalf, using the packaging materials and branding you’ve agreed on in advance.

Step 4: Find suppliers

If you don’t man­u­fac­ture your products yourself, you’ll need to find suitable suppliers for your goods. In the UK, both domestic and in­ter­na­tion­al suppliers can be viable options, depending on your quality re­quire­ments, pricing strategy, and business goals. Online supplier dir­ect­or­ies and mar­ket­places make this process much easier.

Global platforms such as Alibaba are commonly used by UK e-commerce busi­nesses to source products from man­u­fac­tur­ers worldwide. In addition, dir­ect­or­ies like Worldwide Brands list verified whole­salers and man­u­fac­tur­ers that work with online retailers, including those based in the UK.

You can also find UK-based man­u­fac­tur­ers and whole­salers through industry-specific dir­ect­or­ies, trade as­so­ci­ations, and trade fairs, which can be par­tic­u­larly useful if you want shorter delivery routes or to promote locally sourced products.

Choosing a supplier is important for your business success. The re­li­ab­il­ity of the platform itself does not guarantee the quality of the whole­saler. Therefore, carefully examine who you may po­ten­tially conduct business with in the future.

• Establish personal contact by phone or email. Is the supplier easily reachable and do they respond promptly? Are they friendly and service-oriented?
• Order a few samples of products you are con­sid­er­ing for your inventory to get an im­pres­sion of the quality.
• Ask about special terms for regular orders to test the supplier’s flex­ib­il­ity.

Depending on the product, it can be a good idea to col­lab­or­ate with a local man­u­fac­turer. Many local producers offer wholesale supply in addition to their retail store. In such cases, take the op­por­tun­ity to visit and get an im­pres­sion of the product and the vendor. A personal re­la­tion­ship is still the best found­a­tion for ne­go­ti­at­ing at­tract­ive business terms.

Step 5: Plan marketing

Is your online store set up on the internet and all service providers in­teg­rated? Is your social selling system in place? Then it’s time to focus on marketing and ad­vert­ising your products.

As a product seller on the internet, you have many marketing options available that you can combine as you wish. However, when choosing a strategy, you should consider your product and target audience: For example, a lifestyle product aimed at a young audience can be ef­fect­ively marketed on Instagram, while a useful household product might be better sold through Google Ads or with the help of SEO.

New marketing channels like TikTok and YouTube Shorts have offered massive reach for young audiences, es­pe­cially in recent years. Short-form videos provide an ideal op­por­tun­ity to visually showcase your products and engage younger buyers. Use trends and chal­lenges to quickly gain vis­ib­il­ity.

Gain an overview of the methods and basics of online marketing and gather ex­per­i­ence with po­ten­tially suitable marketing formats using a small budget initially before investing larger amounts.

If a marketing channel isn’t de­liv­er­ing strong results at first, it’s best not to rule it out too quickly. Rather than con­tinu­ing to spend budget in­ef­fi­ciently, it can make sense to work with an ex­per­i­enced service provider who can use the channel more ef­fect­ively and get better results through their expertise.

As a cost-effective marketing approach, you can build and manage your own pages and profiles on major social networks such as Instagram or Facebook. Engage with people who are in­ter­ested in your product niche and share content that provides real value. Avoid using your profiles solely for pro­mo­tion­al posts about your own products.

Also, publish in­form­at­ive and detailed articles on your website to reach users who are searching for in­form­a­tion on the topic through Google.

Once potential customers have visited your online shop, you can also try to stay in contact through news­let­ter marketing, which may result in a (repeat) sale later.

Don’t un­der­es­tim­ate the impact of offline marketing when it comes to promoting your online shop. Showcase your business at trade shows and hand out flyers or postcards with a QR code linking to your shop in places your target audience visits, such as cafés, GP surgeries, or libraries. When attending industry meetups or con­fer­ences, bring business cards that include a link to your online shop. You can also create memorable offline campaigns, such as flash mobs or pop-up activ­it­ies, and share them online — these creative actions often have strong viral potential.

What really de­term­ines success in online selling

Selling products online is, in principle, straight­for­ward. If you carefully follow the steps outlined here and take the necessary actions, you can quickly launch your own products on the internet. The real question, however, is whether you’ll succeed in selling them con­sist­ently.

The success of an online shop offering physical products depends on many different factors. While the fun­da­ment­als are easy to grasp, true chal­lenges arise in execution. What really matters is de­vel­op­ing a strong sense for the market, emerging product trends, and new op­por­tun­it­ies.

Using tools such as AI-powered marketing solutions and analytics platforms on an ongoing basis can help you spot trends early and better un­der­stand what customers are looking for. If you’re willing to invest time, keep learning, and actively listen to customer feedback, you’ll have a solid found­a­tion for building a prof­it­able online business — whether as a side project or a full-time venture.
