Install on Shopify

Add PerchLens to a Shopify storefront and track conversion checkouts.

Open your theme's code editor
Shopify admin → Online Store → Themes → Actions (next to your live theme) → Edit code.
Find theme.liquid
In the left file tree, expand 'Layout' and click theme.liquid. This is the wrapper for every storefront page.

Paste the script in the <head>
Add the tracking script just before the closing </head> tag.
```
<script defer src="https://perchlens.com/cv.js" data-site="{SITE_ID}"></script>
```
Set up checkout tracking
For tracking conversions through to checkout, add the same script to Settings → Checkout → Order status page → Additional scripts. This requires Shopify Plus for the order confirmation page; Basic plans only get product/cart pages.
Save + verify
Click Save in the top-right. Visit your storefront once and confirm pageviews appear in the PerchLens dashboard.

Tip: Replace {SITE_ID} in the snippets above with your actual tracking ID. You'll find it in Settings → Tracking after creating a site.

Troubleshooting

Pageviews track but checkout conversion doesn't

Shopify isolates checkout pages — you need Shopify Plus to add scripts there. On Basic, track add-to-cart events as a proxy.

I see double pageviews

Check you haven't pasted the script in both theme.liquid AND a section file. One canonical injection point only.
