Install OCT in 5 minutes

No developer required. No GTM. Just paste one line into your site's <head> and you're tracking leads.

1

Create a project

After creating your account, click New project in the dashboard. Give it a name (e.g. "My Website") and optionally enter your website's domain.

Tip: Enter your domain so OCT can verify the script is installed correctly later.
2

Copy your embed snippet

Your unique snippet is shown on the Project overview page and in Project Settings → Tracking behaviour. It looks like this:

<script src="https://static.offlineconversionstracking.com/v1/oct.js?id=OCT-XXXXXXXX" async ></script>

Replace OCT-XXXXXXXX with your real tracking ID (shown in the dashboard).

3

Add the script to your website

Paste the snippet into the <head> of every page on your site. Choose the method that matches your platform:

WordPress
  1. In your WordPress admin, go to Appearance → Theme File Editor (or use a plugin like "Insert Headers and Footers").
  2. Find your theme's header.php and paste the snippet before the closing </head> tag.
  3. Alternatively, use the Insert Headers and Footers plugin and paste into the "Scripts in Header" box.
Webflow
  1. In the Webflow Designer, go to Project Settings → Custom Code.
  2. Paste the snippet into the Head Code section.
  3. Publish your site. The script will be active on all pages.
Shopify
  1. In Shopify Admin, go to Online Store → Themes → Edit code.
  2. Open theme.liquid and paste the snippet in the <head> section.
HTML / any other platform
Paste the snippet anywhere inside the <head>...</head> block of your HTML layout template — the file that wraps every page on your site.
4

Verify the installation

In your OCT project dashboard, click Verify script. OCT will visit your domain and check that the script tag is present in the HTML source.

Manually verify: Open your website in a browser, right-click → View Page Source, and search for oct.js. If you see it, the script is installed.
5

Submit a test form

Visit your website and submit any form. Return to your OCT dashboard — you should see a new lead appear within a few seconds.

If you arrived from a Google Ad (with a gclid in the URL) before submitting, the click ID will appear in the lead details — ready for export.
