Migration Guide
Migrate from Arc llms.txt
to Index AI.
An honest read on whether the switch fits your store, what stays the same, what changes, the concrete migration path — and the case for staying put if that's actually the right call.
The honest case
Why move from Arc llms.txt?
Arc llms.txt does one thing — generate an llms.txt file for your Shopify store — and does it focused-narrowly. That single file is genuinely useful but it is one slice of the AI-search stack. Index AI ships the full execution layer: llms.txt generation, the complete Schema.org Product suite, IndexNow push, AND an AI Readiness Score that tells you what is still missing. If you only need llms.txt, Arc is fine; if you want a single source of truth for AI-search execution across your store, Index AI is the swap.
What stays the same
- Your Shopify theme, products, sitemap, and URL structure are unchanged.
- Your other SEO tools (classic SEO apps) continue working.
- Your other Shopify Apps continue working without reconfiguration.
- Your existing analytics + tracking carry over.
What changes
- You replace Arc's single-file llms.txt generator with Index AI's broader AI-search execution layer.
- You add the complete Schema.org Product suite injection.
- You add IndexNow push for Bing-aligned AI-answer engines.
- You add the AI Readiness Score — composite diagnostic for the full AI-search posture.
Migration path
The concrete steps.
- 1
Install Index AI
Free tier covers the standard llms.txt + basic Schema + IndexNow setup.
- 2
Configure Index AI as your llms.txt source
Don't run both tools writing llms.txt — pick one source. Index AI is the broader choice if you also want Schema + IndexNow integration.
- 3
Disable Arc llms.txt
Avoid having two tools writing to the same /llms.txt route. Index AI takes over.
- 4
Configure Schema + IndexNow in Index AI
Auto-generated from your catalogue; pings IndexNow on changes.
- 5
Run the AI Readiness Score
Composite diagnostic of your full AI-search posture.
When NOT to switch
If you only need an llms.txt file and your Schema + IndexNow setup is already handled elsewhere, Arc's narrow single-purpose focus is fine. The case for switching to Index AI strengthens when you want a single source of truth across the full AI-search execution layer rather than juggling multiple narrow tools.
