UK brands are altering the online selling methods of their products. Online marketplaces like Amazon, Walmart Marketplace, and TikTok Shop are also providing new opportunities to businesses in order to reach out to customers, boost sales and grow into international markets. These sites are no longer an additional point of sale to many retailers. They are taking centre stage in their eCommerce development strategy.
Nonetheless, expanding the reach of customers does not necessarily imply sustainable growth. Brands should learn how every marketplace operates, enhance their product listings, control advertising expenses and establish effective fulfilment systems. With the growing competition, there is a growing need to have a clear marketplace strategy by the UK businesses.
Why UK Brands are spending more on online marketplaces
The rise of online retail has prompted more UK companies to consider marketplace selling. The Office for National Statistics (ONS) recorded that internet sales constituted 27.5% of the total retail sales in 2025 as compared to 19.2% in 2019. This is an indication of the increased significance of digital shopping in the British retail market.
Amazon remains an important platform for businesses looking to reach online shoppers. Its established customer base, product search features and fulfilment services make it an important option for both new and established brands. Amazon reports that UK small and medium-sized businesses selling through its platform generated more than £3.8 billion in export sales during 2024.
Meanwhile, British companies interested in going abroad are considering Walmart Marketplace. In August 2025, Walmart announced a major initiative to recruit UK and European sellers for its marketplaces in the United States, Canada, Mexico and Chile.
These trends demonstrate how online markets can enable UK brands to go beyond their home sales and explore new markets.
Amazon, Walmart and TikTok Shop Provide Various Growth Opportunities
Although there is similarity in the fundamental nature of services that the two platforms provide, i.e., to connect sellers and customers, they provide varying methods of expanding an online company.
Amazon Marketplace is specifically helpful for brands that are aimed at customers who already search for a particular product. The businesses can enhance their presence by using pertinent keywords and competitive pricing, customer reviews, and sponsored product advertising.
Walmart Marketplace: Another way that UK brands wishing to venture abroad, especially North America, can do so is through Walmart Marketplace. Its expanding network of international sellers provides qualified businesses access to new markets, but the sellers have to be familiar with local laws, shipping rules, and customer satisfaction.
TikTok Shop does not follow the same trend, as it integrates social media content with online shopping. Customers can learn about products via short videos, livestreams and creator recommendations and buy them via the platform.
It is already an opportunity that can be seen in the beauty industry. TikTok reported that TikTok Shop became the UK’s fourth-largest beauty retailer in 2025, with category sales increasing by 60 percent year on year. Although this is data reported by the platform, it shows the increasing significance of social commerce in product discovery.
In the case of UK brands, the selection of the platform is determined by the product, target audience, budget and long-term business objectives.
What Does It Take to Scale on Online Marketplaces?
Growing a marketplace cannot be achieved by merely uploading products and waiting until they get ordered. There are a number of areas that businesses must address.
Product listing: Good product names, search terms, product descriptions, and good quality images ensure that customers can locate and identify products. The significance of marketplace SEO is that internal search results can be enhanced by better-organized items.
Marketplace advertising: Amazon Ads, Walmart Connect and TikTok advertising platforms enable brands to engage potential customers. Nevertheless, companies must keep an eye on advertising expenses, conversion and profit margin. Increased expenditure on advertising may not necessarily pay off.
Inventory and fulfilment: Consistency in stock, proper delivery information and effective order processing are imperative. With businesses selling on various platforms, businesses should not run out of stock, have slow deliveries, or have order processing issues.
Customer experience: Purchases can be affected by reviews, product inquiries, returns, and customer care. Providing accurate product information and responding to customers promptly can help build trust.
The integration of these areas will provide brands with more basis for developing the marketplace in the long term.
The Importance of Marketplace Strategy and Specialist Support
There is a risk of business becoming cumbersome when managing multiple online marketplaces. All the platforms have varying rules of selling, advertising, customer expectations, and measures of performance. A successful strategy on Amazon might require some modifications on Walmart Marketplace or TikTok Shop.
That is why there are expert agencies to which some businesses turn. An expert Amazon and marketplace consultancy can assist brands in the planning of the marketplace, the enhancement of product listings, advertising, and global expansion.
This Way Up is a company based in London and Manchester that is working in this specialist field. Outside assistance can assist companies in finding appropriate marketplaces, performance data, as well as making better decisions on where to allocate their resources.
An eCommerce podcast can also assist brands in discussing the industry and learning the practical aspects of eCommerce, helping them comprehend the changing trends in the marketplace and selling strategies.
The Future of Online Marketplace Growth for UK Brands
Internet marketplaces will probably continue playing a significant role in eCommerce in the UK. Amazon provides well-established product search and selling platforms, Walmart provides opportunities to enter new markets.
Joining additional platforms is not the primary issue that UK brands face. It is making the right marketplaces and developing a strategy that links product visibility, advertising, fulfilment and customer experience.
Those businesses that know such differences will be in a better position to cope with competition, acquire new customers and achieve sustainable growth. As online retail continues to grow, marketplace selling is becoming central to how UK brands compete and expand.
