Arc: llms.txt vs Webrex: SEO Schema & JSON‑LDfor Shopify (2026)

Arc: llms.txt and Webrex: SEO Schema & JSON‑LD are both highly-rated Shopify SEO apps, but cater to different aspects of search engine optimization, particularly in the age of increasingly prevalent Large Language Models (LLMs). Arc: llms.txt positions itself as a simple solution for creating and managing an `llms.txt` file, which it claims helps LLMs like ChatGPT and Gemini index and showcase your store's content. Its strength lies in its one-click generation and automated refresh, making it extremely user-friendly for merchants wanting a quick and easy solution to potentially improve visibility in AI-driven search. It specifically targets merchants interested in directly influencing how LLMs understand and display their products. Webrex: SEO Schema & JSON‑LD takes a more comprehensive approach to SEO, focusing on schema markup to improve visibility in both traditional search engines and AI systems. While also claiming AI-readiness, its strength lies in its robust feature set, including support for various schema types (Product, Review, FAQ, etc.), integrations with multiple review apps, and duplicate schema cleanup. Webrex aims at merchants looking to improve click-through rates and overall SEO performance through structured data, rich snippets, and increased search engine understanding of their products and content. It aims to cater to the full spectrum of SEO, not just LLM indexing.
