Multimodal Shopping Assistant

It seamlessly integrates with your Shopify catalog to provide instant, accurate product recommendations, answer questions about shipping and returns, and even add items to the cart or initiate checkout. This creates a conversational, intuitive shopping experience that mirrors in-store assistance, significantly reducing friction and abandoned carts.
Comprehensive AI Visibility Audit
This proprietary audit tool performs over 30 critical checks in under 60 seconds, with no installation required. It analyzes your store specifically for AI search engine readiness, going far beyond traditional SEO. The audit identifies if your store is blocking AI crawlers, evaluates the quality of your product descriptions for AI citation, and checks for the presence of advanced JSON-LD schema markup that Large Language Models (LLMs) use to understand and recommend products.
Done-For-You AI Optimization
Unlike tools that only identify problems, Zenor provides a complete implementation service. Their team handles all technical fixes required for AI visibility, including configuring your robots.txt to allow access to crawlers from platforms like ChatGPT and Perplexity, implementing rich, structured schema markup tailored for LLMs, and optimizing product content to be AI-ready. This turnkey approach ensures stores become visible in AI search results without requiring merchant technical expertise.
Competitor AI Visibility Benchmarking
Zenor's audit provides contextual intelligence by comparing your store's AI visibility score against direct competitors. This feature highlights your relative standing in the new AI search landscape, offering clear, prioritized insights into what specific gaps need to be closed first to gain a competitive advantage and capture market share from AI-driven product discovery.

Zenor AI
Boosting Conversions for High-Consideration Products
For stores selling complex, feature-rich, or high-value items (e.g., electronics, skincare, supplements), the shopping assistant guides uncertain customers. By answering specific, technical questions in real-time and providing personalized recommendations, it shortens the decision-making process, builds trust, and directly increases conversion rates and average order value.
Capturing Traffic from AI Search Platforms
Merchants who are invisible to AI assistants like ChatGPT and Google AI are missing up to 40% of new product discovery. Zenor's optimization service ensures your products are indexed and cited when users ask AI for recommendations. For example, a store selling "organic face moisturizer for sensitive skin" will appear in AI answers, driving qualified, high-intent referral traffic directly to their product pages.
Reducing Customer Support Overhead
The AI assistant autonomously handles a high volume of repetitive pre- and post-purchase inquiries, such as "What's my order status?", "What is your return policy?", and "Do you ship to my country?". This 24/7 automated support frees human agents to tackle complex issues, improving operational efficiency and reducing support costs while maintaining instant customer satisfaction.
Future-Proofing Against Organic Traffic Decline
With a predicted major shift from traditional search to AI-powered answers, forward-thinking store owners use Zenor to proactively adapt. By auditing and optimizing their store's foundational signals for AI crawlers and LLMs now, they build resilience against the forecasted decline in organic Google traffic, securing a sustainable growth channel for the future.

Zenor AI FAQ
How is AI visibility different from traditional SEO?
Traditional SEO optimizes for search engine algorithms like Google's to rank on Search Engine Results Pages (SERPs). AI visibility optimizes for Large Language Models (LLMs) like those powering ChatGPT, Perplexity, and Google's AI Overviews, which generate conversational answers. This requires different technical signals, such as ensuring AI crawlers can access your site and providing detailed, structured data (schema) that LLMs can easily cite, rather than just targeting keywords for ranking.
What does the free audit check, and do I need to install anything?
The free audit performs over 30 checks in under 60 seconds with zero installation. It analyzes key areas for AI visibility: AI crawler access (checking if your robots.txt blocks platforms like GPTBot), AI-ready description quality, advanced JSON-LD schema markup for LLMs, core web vitals, and traditional SEO fundamentals. You simply enter your store URL; no Shopify API access, app installs, or code changes are required on your end.
What happens after the audit? Is optimization technical?
After the audit, Zenor offers a done-for-you optimization service. Their team handles all technical implementation, which typically includes: configuring your store's robots.txt file to allow all major AI crawlers, writing and implementing enhanced JSON-LD structured data tailored for LLM understanding, and providing guidance on optimizing product content. This process requires no coding or technical work from the merchant.
Why is this specific to Shopify? Can't any store use it?
While the principles of AI visibility apply broadly, Zenor's audit and optimization are built specifically for the Shopify platform. It checks for Shopify-specific issues, understands its theme structure and common app conflicts, and implements fixes that are compatible and optimized for Shopify's ecosystem. This deep platform specialization ensures more accurate audits and reliable, effective implementations compared to generic tools.
