Implementation Guide

Placement Best Practices

Where to Place:

✅ Before closing </body> tag
✅ After main content
✅ With other tracking scripts

Why:

Non-blocking page load
Doesn’t affect performance
Loads in parallel with other scripts

Don’t Place:

❌ In <head> (blocks rendering)
❌ Before critical content
❌ Inline in content

Script Attributes

async attribute:

Loads script asynchronously
Doesn’t block page rendering
Improves page load time

src parameter:

Points to Sellestial CDN
Globally distributed
High availability
Fast load times

Custom User Identification

For advanced implementations with first-party data:

Modify External ID Variable

<script>
  // Set before Sellestial script loads
  window.sellestial_external_id = 'your_user_id_123';
</script>
<script async src="https://cdn.sellestial.com/cs?cid=YOUR_CUSTOMER_ID"></script>

  if (!userIsCustomer) {
    var script = document.createElement('script');
    script.async = true;
    script.src = 'https://cdn.sellestial.com/cs?cid=YOUR_CUSTOMER_ID';
    document.body.appendChild(script);
  }
</script>

Page Filtering

Exclude certain pages:

<script>
  // Don't track checkout or account pages
  var excludedPaths = ['/checkout', '/account', '/admin'];
  var currentPath = window.location.pathname;
  var shouldTrack = !excludedPaths.some(path => currentPath.startsWith(path));

  if (shouldTrack) {
    var script = document.createElement('script');
    script.async = true;
    script.src = 'https://cdn.sellestial.com/cs?cid=YOUR_CUSTOMER_ID';
    document.body.appendChild(script);
  }
</script>

Event Tracking

Track specific events (if supported):

<script>
  window.sellestialTrack = window.sellestialTrack || [];

  // Track button click
  document.getElementById('cta-button').addEventListener('click', function() {
    window.sellestialTrack.push({
      event: 'button_click',
      properties: {
        button_id: 'cta-button',
        page: window.location.pathname
      }
    });
  });
</script>

Troubleshooting

No Visitors Appearing

Check:

Script installed correctly?
Enough traffic to identify?
Visitors mostly US-based?
Time delay for processing?
Dashboard filters applied?

Remember: Only ~25% of US visitors identified

Duplicate Records Created

Possible causes:

Multiple tracking scripts
Script loaded multiple times
External ID not consistent

Solutions:

Check for duplicate scripts
Ensure single script load
Verify external ID logic

Geographic Data Wrong

Common issues:

VPN usage by visitor
Corporate proxy servers
Mobile carrier locations

Note: Location is approximate based on IP

Performance Impact

Concern: Site speed affected

Reality:

Async loading (non-blocking)
CDN delivery (fast)
Minimal payload
No noticeable impact

Verify:

Check Google PageSpeed
Monitor load times
Test with/without script
