Bloomreach released a detailed ecommerce chatbot evaluation guide that categorizes tools into two distinct tiers based on business objective (Bloomreach Blog). Tier 1 support chatbots are designed to reduce support ticket volume by answering post-purchase questions, handling returns, and surfacing FAQ content without routing to live agents. Tier 2 AI shopping agents replicate the experience of a knowledgeable sales associate, using large language models to understand shopper intent, surface relevant products, and guide customers toward purchase.
The guide emphasizes that brands often evaluate the wrong chatbot type for their actual goal, leading to deployment failures and incorrect KPI measurement (Bloomreach Blog). Modern AI chatbots use natural language processing and LLMs to understand conversational queries rather than relying on keyword matching, enabling them to handle complex requests like "Do you have anything that would work for a 10-year-old who just got into hiking?" The guide outlines six evaluation criteria: conversational query understanding, product catalog integration, personalization capabilities, human handoff quality, analytics and reporting, and platform compatibility.
The eight tools reviewed span both tiers, including Tier 1 solutions like Tidio, Intercom, Chatfuel, Gorgias, and ManyChat, alongside Tier 2 options such as Bloomreach's Loomi Conversational Agent (Bloomreach Blog). For commerce practitioners, the key takeaway is that neither tier is inherently superior—the choice depends on whether the priority is support efficiency or revenue conversion, and success metrics must align accordingly.
