Signal ( oRTB/Native )

Google Tag Manager (Recommended)

Recommended Integration Method GTM integration requires no code changes to your website and allows easy enable/disable without deployments.

Setup Steps

Get Your Script from Dashboard

Log into your Panxo dashboard at app.panxo.ai
Navigate to Settings → Integration
Copy your integration script (format: <script async src="https://cdn.panxo.ai/o/{hash}"></script>)

Your Script: Each property receives a unique hash-based script URL. This hash is automatically generated and displayed in your dashboard. Simply copy the complete script tag.

Create GTM Tag

In Google Tag Manager, create a new Custom HTML tag and paste your script:

Custom HTML (example)

<script async src="https://cdn.panxo.ai/o/6c6cfb20039e1773"></script>

Example Script Format:

Component

Description

Example

URL

Hash-based script URL

https://cdn.panxo.ai/o/6c6cfb20039e1773

Hash

Unique identifier for your property

6c6cfb20039e1773

Important: Use the exact script provided in your dashboard. Each property has a unique hash that cannot be shared or reused.

Configure Trigger

Set trigger to fire on "All Pages" or specific pages
Use "Page View" trigger type

Test & Publish

Use GTM Preview mode to verify script loads
Publish container when ready

Verification

Verification Checklist:

Script appears in Network tab as /o/{hash} (e.g., /o/6c6cfb20039e1773)
Dashboard shows "Script Verified" status in real-time (verification happens immediately after script integration)

Direct Script Integration

When to Use:

If you don't use GTM
Need more control over script placement
WordPress sites (consider plugin instead)

Setup

Add to your <head> section using the script from your dashboard:

Example (head)

<head>
  <!-- Other head content -->
  <script async src="https://cdn.panxo.ai/o/6c6cfb20039e1773"></script>
</head>

Important Notes:

Use the exact script provided in your dashboard (Settings → Integration)
Each property has a unique hash-based URL
Place in <head> for early detection
async attribute ensures non-blocking load
Script auto-initializes when DOM is ready

WordPress Plugin

When to Use:

WordPress-powered sites
Want automatic ads.txt management
Prefer plugin-based integration
Zero-configuration setup

Installation

Go to WordPress admin → Plugins → Add New

Search for "Panxo AI Monetization"

Click "Install Now" and "Activate"

Plugin URL: WordPress.org Plugin Directory

Automatic Configuration

Zero-Configuration Setup The plugin handles everything automatically. Setup completes in less than 1 minute.

What the Plugin Does Automatically:

Registers your WordPress site with Panxo
Creates your property
Integrates the Panxo script into <head>
Updates your ads.txt file with required entries
Begins the learning process

Verification

Dashboard shows "Script Verified" and "Ads.txt Verified" when complete
Monitor learning phase progress from WordPress dashboard

Prebid.js / OpenRTB Integration

When to Use:

Already using Prebid.js for header bidding
Want Panxo to compete in your existing auction
Running a multi-SSP setup
Direct OpenRTB integration

Best For: Publishers with existing Prebid infrastructure who want to add AI traffic monetization to their demand stack.

Prerequisites

From your Panxo Dashboard (Settings > OpenRTB/Prebid):

Endpoint Key - A unique hash for your property (e.g., 06dc70992da98be6)
Signal Script URL - https://cdn.panxo-sys.com/o/{ENDPOINT_KEY}

Important Domain: For Prebid/OpenRTB, use cdn.panxo-sys.com (NOT cdn.panxo.ai). This is required for proper cookie syncing.

Steps

Install Signal Script

The Signal script must load before Prebid.js:

head (signal + prebid)

<head>
  <!-- Panxo Signal Script - MUST load before Prebid -->
  <script async src="https://cdn.panxo-sys.com/o/YOUR_ENDPOINT_KEY"></script>
  
  <!-- Prebid.js -->
  <script async src="prebid.js"></script>
</head>

The Signal script:

Creates user identity (panxo_uid) in localStorage
Detects AI-referred traffic
Enables Panxo to bid on your inventory

Configure Prebid Ad Unit

adUnits example

var adUnits = [{
  code: 'ad-slot-1',
  mediaTypes: {
    banner: {
      sizes: [[300, 250], [728, 90], [320, 50]]
    }
  },
  bids: [{
    bidder: 'panxo',
    params: {
      propertyKey: '06dc70992da98be6'  // Your endpoint key (same hash as Signal script)
    }
  }]
}];

Initialize Prebid

Prebid initialization

var pbjs = pbjs || {};
pbjs.que = pbjs.que || [];

pbjs.que.push(function() {
  pbjs.addAdUnits(adUnits);
  
  pbjs.requestBids({
    timeout: 2000,
    bidsBackHandler: function() {
      var winner = pbjs.getHighestCpmBids('ad-slot-1')[0];
      if (winner) {
        renderAd(winner);
      }
    }
  });
});

function renderAd(bid) {
  var container = document.getElementById('ad-slot-1');
  var iframe = document.createElement('iframe');
  iframe.width = bid.width;
  iframe.height = bid.height;
  iframe.frameBorder = '0';
  container.appendChild(iframe);
  iframe.contentWindow.document.open();
  iframe.contentWindow.document.write(bid.ad);
  iframe.contentWindow.document.close();
}

How Bidding Works

AI-Only Bidding Panxo only bids when AI traffic is detected. You'll only receive bids for users coming from ChatGPT, Perplexity, Claude, etc.

Signal script loads and creates panxo_uid in localStorage
Signal script detects if user came from AI and stores signal
Prebid requests bids from all configured bidders
Panxo adapter reads panxo_uid and sends OpenRTB request
Panxo server checks if user has AI signal and returns bid
If Panxo wins auction, ad is displayed

Expected Performance

Metric

Typical Value

CPM

$5 - $15

Fill Rate

5-15% of total traffic

Why Low Fill Rate is Normal Panxo targets only AI traffic (typically 5-15% of visits). This focused approach delivers premium CPMs without affecting your other demand sources.

<!DOCTYPE html>
<html>
<head>
  <!-- 1. Panxo Signal Script (MUST load first) -->
  <script async src="https://cdn.panxo-sys.com/o/06dc70992da98be6"></script>
  
  <!-- 2. Prebid.js -->
  <script async src="prebid.js"></script>
  
  <script>
    var pbjs = pbjs || {};
    pbjs.que = pbjs.que || [];
    
    pbjs.que.push(function() {
      pbjs.addAdUnits([{
        code: 'banner-ad',
        mediaTypes: { banner: { sizes: [[300, 250], [728, 90]] } },
        bids: [{
          bidder: 'panxo',
          params: { propertyKey: '06dc70992da98be6' }
        }]
      }]);
      
      pbjs.requestBids({
        timeout: 2000,
        bidsBackHandler: function() {
          var winner = pbjs.getHighestCpmBids('banner-ad')[0];
          if (winner) {
            var container = document.getElementById('banner-ad');
            var iframe = document.createElement('iframe');
            iframe.width = winner.width;
            iframe.height = winner.height;
            iframe.frameBorder = '0';
            container.appendChild(iframe);
            iframe.contentWindow.document.open();
            iframe.contentWindow.document.write(winner.ad);
            iframe.contentWindow.document.close();
          }
        }
      });
    });
  </script>
</head>
<body>
  <div id="banner-ad"></div>
</body>
</html>

Testing

Enable Prebid debug mode:

Enable debug

pbjs.setConfig({ debug: true });

Check browser console for:

Panxo: Sending bid request - Request sent
Panxo: Bid received - Bid returned
Panxo: User ID not found - Signal script not loaded

Verify Signal script:

Check panxo_uid

console.log(localStorage.getItem('panxo_uid'));
// Should show: "d9433353-xxxx-xxxx-xxxx-xxxxxxxxxxxx"

Troubleshooting

No bids received?

Verify Signal script URL uses cdn.panxo-sys.com (NOT cdn.panxo.ai)
Check localStorage for panxo_uid (DevTools > Application > Local Storage)
Verify endpoint key matches between Signal script and Prebid params
Panxo only bids if user has AI signal (came from AI recently)

Low fill rate?

This is expected - Panxo only bids on AI-referred traffic
Check AI traffic percentage in your Panxo dashboard
