How to Measure Conversions

SealMetrics allows you to track both conversions (goal completions with monetary value) and microconversions (user interactions and funnel steps).

Quick Start​

1. Install the Tracker​

First, add the tracker to your website:

<script src="https://t.sealmetrics.com/t.js?id=YOUR_ACCOUNT_ID" defer></script>

2. Track a Conversion​

Call sealmetrics.conv() when a conversion happens:

// Track a purchase
sealmetrics.conv('purchase', 99.99);

// Track a purchase with additional data
sealmetrics.conv('purchase', 99.99, {
  order_id: 'ORD-12345',
  currency: 'EUR'
});

3. Track a Microconversion​

Call sealmetrics.micro() for user interactions:

// Track add-to-cart
sealmetrics.micro('add_to_cart');

// Track with additional data
sealmetrics.micro('add_to_cart', {
  product_id: 'SKU-123',
  product_name: 'Blue Shoes'
});

Conversion Examples​

E-commerce Purchase​

sealmetrics.conv('purchase', 149.99, {
  order_id: 'ORD-2025-001234',
  currency: 'EUR',
  payment_method: 'credit_card'
});

Lead Form Submission​

sealmetrics.conv('lead', 0, {
  form_name: 'contact_form',
  source: 'homepage'
});

Newsletter Signup​

sealmetrics.conv('signup', 0, {
  list: 'weekly_newsletter',
  source: 'footer'
});

SaaS Subscription​

sealmetrics.conv('subscription', 49, {
  plan: 'pro_monthly',
  currency: 'USD'
});

Microconversion Examples​

Add to Cart​

sealmetrics.micro('add_to_cart', {
  product_id: 'SKU-456',
  product_name: 'Running Shoes',
  price: '89.99'
});

Checkout Step​

sealmetrics.micro('begin_checkout', {
  items_count: '3',
  cart_value: '267.99'
});

Video Play​

sealmetrics.micro('video_play', {
  video_id: 'product-demo',
  video_title: 'Product Tour'
});

Button Click​

document.querySelector('.cta-button').addEventListener('click', function() {
  sealmetrics.micro('cta_click', {
    button_text: this.textContent,
    button_location: 'hero'
  });
});

Implementation Patterns​

On Page Load (Thank You Page)​

<script src="https://t.sealmetrics.com/t.js?id=YOUR_ACCOUNT_ID" defer></script>
<script>
  window.addEventListener('load', function() {
    sealmetrics.conv('purchase', 149.99, {
      order_id: 'ORD-12345',
      currency: 'EUR'
    });
  });
</script>

On Button Click​

<button onclick="trackConversion()">Complete Purchase</button>

<script>
  function trackConversion() {
    sealmetrics.conv('purchase', 99.99, {
      order_id: 'ORD-12345'
    });
  }
</script>

On Form Submit​

<form onsubmit="trackLead()">
  <!-- form fields -->
  <button type="submit">Submit</button>
</form>

<script>
  function trackLead() {
    sealmetrics.micro('form_submit', {
      form_name: 'contact'
    });
  }
</script>

Dynamic Values​

From JavaScript Variables​

var orderData = {
  total: 149.99,
  id: 'ORD-12345',
  currency: 'EUR'
};

sealmetrics.conv('purchase', orderData.total, {
  order_id: orderData.id,
  currency: orderData.currency
});

From Server-Side (PHP)​

<script>
  window.addEventListener('load', function() {
    sealmetrics.conv('purchase', <?php echo $order->total; ?>, {
      order_id: '<?php echo $order->id; ?>',
      currency: '<?php echo $order->currency; ?>'
    });
  });
</script>

From Data Attributes​

<button
  data-product-id="SKU-123"
  data-product-name="Blue Shoes"
  data-price="89.99"
  onclick="trackAddToCart(this)"
>
  Add to Cart
</button>

<script>
  function trackAddToCart(btn) {
    sealmetrics.micro('add_to_cart', {
      product_id: btn.dataset.productId,
      product_name: btn.dataset.productName,
      price: btn.dataset.price
    });
  }
</script>

Checking if Tracker is Loaded​

Always verify the tracker exists before calling it:

if (typeof sealmetrics !== 'undefined') {
  sealmetrics.conv('purchase', 99.99);
}

Or wait for it to load:

window.addEventListener('load', function() {
  if (typeof sealmetrics !== 'undefined') {
    sealmetrics.conv('purchase', 99.99);
  }
});

Property Guidelines​

  • All values are strings — Numbers are automatically converted
  • Use descriptive names — product_id not pid
  • Be consistent — Use the same property names across your site
  • Don't include PII — No email addresses, phone numbers, etc.

Troubleshooting​

Conversions not appearing​

  1. Check the browser Network tab for requests to t.sealmetrics.com
  2. Verify your Account ID is correct
  3. Wait 1-2 minutes and check the Real-time report
  4. Ensure the domain is authorized in your SealMetrics account

Duplicate conversions​

  1. Implement deduplication (see E-commerce Guide)
  2. Only fire the conversion once per order
  3. Use server-side flags to mark orders as tracked
