# How to Measure Conversions

Canonical page: https://docs.sealmetrics.com/getting-started/measure-conversions

To measure conversions in Sealmetrics, install the tracker and call `sealmetrics.conv('type', amount?, { ...props })` when a goal completes — for example `sealmetrics.conv('purchase', 99.99)`. Use `sealmetrics.conv()` for **conversions** (goal completions with an optional monetary value like purchases, signups, and leads) and `sealmetrics.micro()` for **microconversions** (user interactions and funnel steps such as add-to-cart or video plays).

---

## Quick Start

### 1. Install the Tracker

First, add the tracker to your website:

```html
<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. The signature is `sealmetrics.conv('type', amount?, { ...props })` — the `amount` is optional (only added to the event when it's a number), and the properties object is optional too:

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

// Track a conversion with no monetary value
sealmetrics.conv('lead');

// Track a purchase with additional data
sealmetrics.conv('purchase', 99.99, {
  currency: 'EUR',
  payment_method: 'credit_card'
});
```

### 3. Track a Microconversion

Call `sealmetrics.micro()` for user interactions:

```javascript
// 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'
});
```

## Conversions vs Microconversions

| Aspect | Conversion | Microconversion |
|--------|------------|-----------------|
| **Purpose** | Goal completion | Progress/engagement |
| **Monetary value** | Optional (amount parameter) | No |
| **Function** | `sealmetrics.conv()` | `sealmetrics.micro()` |
| **Examples** | Purchase, signup, lead | Add to cart, video play, scroll |

---

## Conversion Examples

### E-commerce Purchase

```javascript
sealmetrics.conv('purchase', 149.99, {
  currency: 'EUR',
  payment_method: 'credit_card'
});
```

### Lead Form Submission

```javascript
// Properties live in the third argument; pass 0 as the amount when there is no monetary value
sealmetrics.conv('lead', 0, {
  form_name: 'contact_form',
  source: 'homepage'
});
```

### Newsletter Signup

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

### SaaS Subscription

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

---

## Microconversion Examples

### Add to Cart

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

### Checkout Step

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

### Video Play

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

### Button Click

```javascript
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)

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

### On Button Click

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

<script>
  function trackConversion() {
    sealmetrics.conv('purchase', 99.99, {
      currency: 'EUR'
    });
  }
</script>
```

### On Form Submit

```html
<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

```javascript
var orderData = {
  total: 149.99,
  currency: 'EUR'
};

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

### From Server-Side (PHP)

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

### From Data Attributes

```html
<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:

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

Or wait for it to load:

```javascript
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 Site ID is correct
3. Check the **Conversions** report (set the date range to today); hits arrive in seconds, so the **Last hit** timestamp at the top right of the **Overview** report should already show your test visit
4. Ensure the domain is authorized in your Sealmetrics account

### Duplicate conversions

1. Implement deduplication (see [E-commerce Guide](/implementation/ecommerce-conversion-tracking/ecommerce-setup-guide))
2. Only fire the conversion once per order
3. Use server-side flags to mark orders as tracked
