How to track leads and sales from Kartra

AT A GLANCE

With Kartra, NEMO tracks which link brings each lead and which link brings each sale with no pixels and no Google Analytics. Know which link or video feeds your Kartra pages — leads on your thank-you page and sales via tag. Kartra has no global code: the script goes page by page (and its field wraps whatever you paste in <script> on its own, so you paste plain JS — the code below comes ready). The method is “The script on your site” (server-side · highest reliability): Paste one line (nemo.js) once on your site. From then on, when someone arrives through one of your links, NEMO remembers their source for 90 days and fills in the hidden field of your forms automatically. If you manage your pages with Sites, you can sync the tracking codes across all of them (Global Site Elements → SEO & Tracking Codes). The full connection is 5 steps and you verify it with a single test click.

How does each Kartra lead arrive with its source?

The script on your site · Server-side · highest reliability

Kartra has no global code: the script goes page by page (and its field wraps whatever you paste in <script> on its own, so you paste plain JS — the code below comes ready).

1. On each page of your funnel: Page Builder → Settings → Tracking Codes → Header section → paste this (plain JS, WITHOUT <script> tags): Open Kartra

   var s = document.createElement("script");
   s.src = "https://nemolink.app/nemo.js";
   s.defer = true;
   document.head.appendChild(s);

2. Point your NEMO link at the first page of the funnel: the source is saved for 90 days.
3. On the opt-in thank-you page, paste this version (it loads the script AND records the lead):

   var s = document.createElement("script");
   s.src = "https://nemolink.app/nemo.js";
   s.defer = true;
   document.head.appendChild(s);
   
   document.addEventListener("DOMContentLoaded", function () {
     if (window.nemo) window.nemo.track("lead", { event_name: "Registration" });
   });

Note: If you manage your pages with Sites, you can sync the tracking codes across all of them (Global Site Elements → SEO & Tracking Codes).

How is each Kartra sale attributed?

The purchase tag · Tag-based · high reliability

Kartra tags buyers in ITS own CRM, not in your email platform — the bridge is a two-step Zap.

1. Create your purchase tag in Kit, MailerLite or ActiveCampaign and save it in NEMO (“Conversion attribution” → sales).
2. In Zapier: Kartra trigger “Customer Buys Product” → action in your email platform: find the subscriber by email and add the tag.

Note: The buyer must already be on your list (they came through your link → their source is saved). If they buy with a different email, the sale can't be attributed.

Check it in one minute

1. Click your own NEMO link and leave a test email in the opt-in.
2. The lead shows up in your NEMO dashboard when you land on the thank-you page.
3. Tag that test subscriber: the sale shows up attributed to the same source.

Frequently asked questions

What do I do if the script doesn't load / the page breaks?

You pasted the whole <script> tag into Tracking Codes. Kartra already wraps it for you: paste ONLY the JS code from this guide.

What do I do if the lead arrives as “no source”?

The loader must be on the FIRST page (where the NEMO link lands), not just on the thank-you page.

What do I do if purchases don't come through as sales?

Check the Zap (“Customer Buys Product” → add tag) and that the tag name matches EXACTLY the one saved in NEMO.
