At Rankwit, we specialize in helping merchants take advantage of OpenAI’s Agentic Commerce Protocol (ACP).
Our team manages the entire integration lifecycle, from mapping your product catalog to OpenAI’s structured feed specification, to building the checkout API endpoints and connecting secure payment providers like Stripe.
By partnering with Rankwit, your business can:
We tailor solutions to both enterprise and custom e-commerce platforms, ensuring a scalable and future-ready architecture.
Security is baked into the protocol's core. Unlike "headless" automation, WebMCP operates within the user’s current browser session:

Large Language Models (LLMs) like GPT are trained on vast amounts of text data to learn the patterns, structures, and relationships between words. At their core, they predict the next word in a sequence based on what came before—enabling them to generate coherent, human-like language.
This matters for GEO (Generative Engine Optimization) because it means your content must be:
By understanding how LLMs “think,” businesses can optimize content not just for humans or search engines—but for the AI models that are becoming the new discovery layer.
Bottom line: If your content helps the model predict the right answer, GEO helps users find you.
Shopping Research is a feature in ChatGPT that acts as a personalized shopping assistant.
Simply describe what you’re looking for, such as “a lightweight laptop for travel”, and ChatGPT gathers product details, reviews, specs, prices, and comparisons from the web.
You can refine the results by marking products as “Not interested” or “More like this”, helping ChatGPT understand your preferences.
At the end, you receive a custom buyer’s guide that explains the pros, cons, and trade-offs of each option, making your purchase process easier and more informed.
Your privacy remains a priority when using Shopping Research.
ChatGPT does not send your personal information, queries, or preferences to retailers or third-party sites.
The tool simply gathers publicly available product information online, such as specifications, reviews, and prices, and organizes it into a personalized buyer’s guide for you.
You stay in full control, and no personal data is exchanged during the process.
Generative Engine Optimization (GEO) and Answer Engine Optimization (AEO) are closely related strategies, but they serve different purposes in how content is discovered and used by AI technologies.

AEO helps you be the answer in AI search results. GEO helps you be the source that generative AI platforms trust and cite.
Together, these strategies are essential for maximizing visibility in an AI-first search landscape.
ChatGPT Instant Checkout is a new capability since 2025 developed by OpenAI that allows users to discover, configure, and purchase products directly within ChatGPT without leaving the conversation.
This functionality is powered by the Agentic Commerce Protocol (ACP), an open standard that defines how merchants’ systems interact with AI agents.
Merchants connect their product catalog through a structured product feed, expose checkout endpoints via the Agentic Checkout API, and process payments securely through delegated payment providers like Stripe.
Together, these layers create a smooth, conversational shopping experience that merges AI discovery with secure e-commerce execution.
The transformer is the foundational architecture behind modern LLMs like GPT. Introduced in a groundbreaking 2017 research paper, transformers revolutionized natural language processing by allowing models to consider the entire context of a sentence at once, rather than just word-by-word sequences.
The key innovation is the attention mechanism, which helps the model decide which words in a sentence are most relevant to each other, essentially mimicking how humans pay attention to specific details in a conversation.
Transformers make it possible for LLMs to generate more coherent, context-aware, and accurate responses.
This is why they're at the heart of most state-of-the-art language models today.
Generative Engine Optimization (GEO) is becoming increasingly critical as user behavior shifts toward AI-native search tools like ChatGPT, Gemini, and Perplexity.
According with Bain, recent data shows that over 40% of users now prefer AI-generated answers over traditional search engine results.
This trend reflects a major evolution in how people discover and consume information.
Unlike traditional SEO, which focuses on ranking in static search results, GEO ensures that your content is understandable, relevant, and authoritative enough to be cited or surfaced in LLM-generated responses.
This is especially important as AI platforms begin to integrate live web search capabilities, summaries, and citations directly into their answers.
The urgency is amplified by user traffic trends. According to Similarweb data (see chart below), ChatGPT visits are projected to surpass Google’s by December 2026 if current growth continues.
This suggests that visibility in LLMs may soon be as important—if not more—than traditional search rankings.

RankWit continuously scans generative AI engines like ChatGPT, Gemini, and Perplexity to see if, when, and how your content is referenced. We then aggregate this data into an easy-to-read dashboard, showing:
