AI in e-commerce: how to apply technology to sell more and reduce costs.

Artificial Intelligence is already impacting e-commerce at all levels, from how products are presented to how customers discover, compare, and decide what to buy. Platforms like Nuvemshop, which invested over R$ 50 million in AI solutions by 2025, are increasingly innovating in these technologies for entrepreneurs. According to Ecommerce na Prática , a global leader in e-commerce education, this scenario represents a new era of opportunities for those who want to innovate and scale their operations more efficiently.

“We are living through a revolution as big as the beginning of the internet. Artificial intelligence is not a passing trend; it is a tool that redefines how people consume, search for, and interact with brands. As a reference, according to a study by Sellers Commerce, companies that adopt AI-based strategies register between 10% and 12% increase in revenue. Those who know how to apply it strategically will come out ahead,” says Fábio Ludke, specialist at Ecommerce na Prática.

Check out five practical ways to use AI to grow your e-commerce business:

1. Optimize product titles and descriptions: AI has already changed the way consumers discover products online. Tools like Amazon AI, ChatGPT, and Copy.ai can generate dynamic titles and descriptions that adapt to the customer's search intent. “Today, the focus is no longer on stuffing the title with keywords, but rather on understanding natural language and what the customer really wants to find. That's what improves ranking and increases conversions,” explains Ludke.
2. Implement conversational assistants and intelligent search: the shopping experience is becoming increasingly conversational. Solutions like Nuvem Chat and Amazon Rufus allow customers to ask complex questions and receive personalized recommendations in real time. "Consumers want to talk to brands, not just click on menus. AI makes customer service more human and direct, reducing friction and increasing engagement," says the expert.
3. Simplify the analysis of reviews and comments: reading and interpreting reviews is one of the factors that most influences the purchase decision, but also one of the most time-consuming tasks for the consumer. AI is solving this problem by automatically synthesizing large volumes of comments into practical insights, highlighting the most recurring patterns and perceptions. “Sentiment analysis tools like Google Natural Language allow you to immediately understand what customers value and what needs improvement. This helps entrepreneurs act based on real data, not just isolated impressions,” emphasizes Ludke.
4. Bet on personalized sizing and recommendations: AI models already cross-reference information from returns, measurements, and purchasing patterns to suggest the ideal size and even fit adjustments. Technologies like Vue.ai and Fit Finder help fashion brands reduce returns and increase customer satisfaction. “Personalizing is about delivering security. When the customer feels that the product was tailor-made for them, loyalty happens naturally,” explains the expert.
5. Prevent fraud and gain operational efficiency: behind the scenes, AI is also revolutionizing security. Gateways and marketplaces already use predictive technology to identify suspicious patterns and automatically block scams. “Fraud is an invisible cost, and AI is a powerful ally in prevention. In addition to protecting cash flow, it allows entrepreneurs to focus on strategy and business growth,” adds Ludke.

According to the expert, the intelligent use of AI is what will separate ordinary businesses from truly innovative operations. "The tools are accessible to everyone, but the difference lies in who understands the purpose behind them. AI is the ideal partner for those seeking efficiency, personalization, and sustainable growth," he concludes.
