Yarvi's default setup is the pixel, which it adds when you open the app. It sees shoppers who arrive from an AI answer and agents that drive a real browser.
Some agents fetch your pages without a browser, so they never run the pixel. Yarvi has a Cloudflare Worker that can see those reads for stores whose domain runs through Cloudflare. It is not offered to stores yet. Shopify does not support putting a proxy in front of a Shopify store, so Yarvi is testing it on its own store first, and will not ask you to set it up until that test is done and the setup steps are written.
If you see a Worker step in Settings in the Yarvi app, you can leave it alone. Nothing in Yarvi needs it, and every view works on the pixel.
If your store already runs through Cloudflare and you want to hear when the Worker is ready, ask in Help in the Yarvi app and Ned will follow up.
