Agentic AI in Ecommerce: Driving Smarter Decisions and Seamless Experiences

Picture this: A shopper lands on your ecommerce site and is instantly guided by an AI-powered agent that not only understands their intent but takes action, comparing prices, personalizing product recommendations in real time, streamlining the checkout process, and even initiating post-purchase support. That’s the power of agentic AI.

Unlike traditional artificial intelligence systems that rely heavily on human input to function, agentic AI leverages autonomous agents designed to operate independently across complex workflows. These AI agents interpret goals, make autonomous decisions, and execute actions without constant human intervention. For ecommerce professionals, agentic AI represents a leap forward in automation, customer engagement, and decision-making. As businesses face rising customer expectations and tighter competition, agentic AI offers the opportunity to optimize operations, deliver personalized experiences, and build a scalable ecosystem of intelligent tools that drive growth. Thought leaders across platforms like LinkedIn are already discussing how this shift is redefining ecommerce strategy.

What is agentic AI?

Agentic AI refers to a new class of AI systems designed to act with autonomy, capable of setting goals, making decisions, and taking action without direct human oversight. Rooted in autonomous agents and advances in machine learning, this form of AI goes beyond simple automation to deliver intelligent, proactive behavior. Whereas traditional AI is typically rule-based and reactive, such as automated chatbots with pre-defined responses that don’t evolve over time, agentic AI uses algorithms, real-time data, and orchestration capabilities to dynamically adapt and respond. It’s not just following instructions, it’s identifying the best course of action based on context.

Similarly, while genAI focuses on creating content using large language models (LLMs) like ChatGPT or tools from OpenAI, agentic AI layers on goal orientation and autonomy. It doesn’t just generate responses, it executes multi-step tasks to support outcomes across business operations.

For example, genAI could be used to give you a list of all the top-rated Italian restaurants open late on Fridays, but in the future, agentic AI could look at your schedule and make a reservation every Friday night for whichever restaurant has availability.

This shift has powerful implications for decision-making and task execution. Agentic AI enables commerce platforms to anticipate needs, automate repetitive tasks, and proactively engage shoppers, optimizing both the customer journey and backend workflows.

The rise of agentic AI in ecommerce

The adoption of agentic AI is accelerating across retail and ecommerce, driven by growing consumer expectations for personalized, real-time shopping experiences and operational agility. Where early uses of AI focused on rule-based chatbots and basic automation, today’s AI agents can independently optimize merchandising, manage customer inquiries, and execute complex workflows with minimal human intervention.

Connecting the dots with agentic AI.

This shift is fueled by several key drivers. First, shoppers now demand hyper-personalized interactions, from product recommendations to dynamic price adjustments, delivered seamlessly across digital touchpoints. Agentic AI enables ecommerce platforms to tailor offers, guide product discovery, and optimize the customer journey in real time. 

Google’s AI Mode is an example of agentic AI already being incorporated into the ecommerce shopping journey. It introduces powerful tools like price tracking and automated checkout that let shoppers set specific product preferences, such as desired size, color, and budget. Once these criteria are saved, the AI keeps an eye on listings across the web. When a match is found and the price drops, AI Mode can:

• Send a price drop notification

• Automatically add the item to the retailer’s cart

• Pre-fill checkout information

• Finalize the purchase securely through Google Pay

Importantly, users retain full control. AI handles the heavy lifting, but shoppers still review and approve all purchase details before anything is completed.

Appearing in AI search results.

Second, the rise of omnichannel commerce has added layers of complexity to backend operations. Retailers need scalable automation that integrates smoothly with APIs across multiple channels and platforms, like Amazon and Salesforce, plus a real-time ecosystem of tools to support a unified brand experience.

Retailers need to account for AI search platforms in their channel mix as well. Shoppers are searching on AI platforms like ChatGPT and Perplexity to find product recommendations, so how can brands make sure to appear in those search results? 

AI platforms primarily find products in three ways:

1. AI platforms scrape unstructured product data from websites.

AI crawls sites across the web to find products that match a user’s query. This method gives retailers the least control over how their product listings show up in AI search results. Retailers need to make sure their data is structured and optimized consistently so that AI can extract accurate and relevant data from sites, including third-party marketplaces like Amazon or ad channels like Google Shopping.

2. Model Context Protocols (MCPs) provide AI platforms a structured blueprint for finding product data.

Ecommerce platforms are developing API-based frameworks to give AI platforms more direction for crawling and retrieving site data. Retailers are still dependent on AI platforms to find their site, but they have more control over the data that AI picks up for recommending products. 

3. Syndication platforms like Feedonomics provide data directly to AI platforms. 

For maximum control over the product data that is used by AI in product recommendations, retailers can use a syndication platform to create highly structured and complete product feeds, then deliver them directly to platforms like Perplexity and OpenAI. Feedonomics and BigCommerce recently announced a partnership with Perplexity to enable retailers to provide product data directly to the AI platform, enabling better shopping experiences for users and better visibility for retailers.

“Some aspects of the AI future are already clear. Consumers want agentic experiences throughout their shopping journey, and they turn to Perplexity for accurate answers they can trust,” said Taz Patel, Head of Advertising and Shopping at Perplexity. “When our systems can ingest clean, well-organized product information with rich attributes, consistent taxonomy, and up-to-date availability, the results speak for themselves: more relevant search experiences, higher conversion rates and better alignment with shopper intent. With Feedonomics delivering AI-ready data to Perplexity’s powerful and highly-trusted answer engine, we are setting a new standard for ecommerce search."

Streamlining and speeding up operations.

Finally, businesses are under pressure to reduce operational costs while increasing efficiency. According to Gartner, by 2029, agentic AI will autonomously resolve 80% of common customer service issues, offering up to a 30% reduction in costs and significantly improving response speed. These capabilities also extend into fintech, powering fraud detection, payment optimization, and intelligent credit risk modeling.

Payment providers such as Mastercard are also exploring agentic AI to enhance fraud prevention and streamline digital payments through autonomous risk assessments.

Unlike traditional AI, which is often limited to task-specific responses or content generation through generative AI, agentic AI takes proactive control. These systems don’t just react, they plan, execute, and adapt, providing a powerful foundation for AI-driven digital commerce transformation.

From personalized landing pages to dynamic product recommendations and smart content delivery, AI agents adapt to each customer’s behavior, preferences, and stage in the customer journey. This means a first-time visitor might see a curated homepage focused on bestsellers, while a returning customer is shown in-cart reminders or loyalty-driven upsells.

Because agentic AI operates continuously, it refines its understanding with every interaction, pulling from customer data, purchase history, and even contextual signals like location or time of day. The result: more relevant interactions, faster paths to purchase, and a customer experience that feels genuinely intuitive.

Cost savings and improved scalability.

As ecommerce brands grow, so do operational demands, often requiring larger teams to manage support, merchandising, and logistics. Agentic AI flips this equation by allowing businesses to scale without growing overhead at the same rate. By automating critical functions, brands can reduce reliance on manual labor and reinvest in strategic growth.

One of the clearest examples is in customer service. With autonomous agents resolving FAQs, routing support tickets, and proactively assisting shoppers, brands can significantly reduce labor costs while delivering faster, more consistent service.

Beyond support, agentic AI also reduces costs in areas like catalog updates, fraud detection, and campaign management, enabling brands to run leaner while expanding their reach. 

Smarter decision-making with real-time data.

Agentic AI empowers ecommerce brands with a continuous flow of actionable insights, enabling faster, more accurate decision-making across the business. By processing real-time data from shopper behavior, inventory levels, sales trends, and external signals, these systems surface opportunities and flag issues before they impact performance.

Whether it's adjusting pricing in response to demand, optimizing campaigns mid-flight, or fine-tuning product recommendations, AI-driven decisions happen instantly, without waiting for manual analysis or delayed reports. This agility allows brands to stay ahead of shifting consumer expectations and market dynamics.
