Our Verdict
For merchants prioritizing future-proofing their SEO strategy and optimizing their store's visibility to AI crawlers, Arc: llms.txt appears to be the clear winner. Its focus on creating and maintaining an llms.txt file caters specifically to the evolving landscape of AI-driven search.

Unless substantial improvements are made, Arc: llms.txt is the stronger recommendation for most Shopify merchants looking to optimize their store for future AI-driven discovery.
