How to Use
[{"step":"Define your marketing goal and platform","action":"Replace [SPECIFIC MARKETING GOAL] and [PLATFORM] in the prompt template with your exact use case (e.g., 'tracking form abandonment on a Shopify checkout page'). Specify the validation tool (e.g., Google Analytics DebugView)."},{"step":"Generate the script","action":"Paste the prompt template into your AI tool (Claude/ChatGPT) and run it. Review the generated script for accuracy, ensuring it matches your website's DOM structure and marketing stack."},{"step":"Implement the script","action":"Add the script to your website either directly in the HTML, via Google Tag Manager (as a Custom HTML tag), or through your CMS's JavaScript injection feature. Replace placeholder IDs (e.g., 'ad-container') with your actual element IDs/classes."},{"step":"Test and validate","action":"Use the provided validation instructions to verify the script works. Check browser console for errors, test in multiple browsers, and monitor the impact using your analytics tool (e.g., GTM preview mode or Hotjar recordings)."},{"step":"Monitor and iterate","action":"Track key metrics (e.g., form completions, CTR, or scroll depth) before and after implementation.

Usage Examples
Prompt Template
Generate a JavaScript script for [SPECIFIC MARKETING GOAL: e.g., 'tracking form abandonment rates on a lead capture page', 'A/B testing button color impact on CTR', or 'dynamically adjusting ad creatives based on user scroll depth']. The script should be self-contained, use modern ES6+ syntax, and include comments explaining each key section. Ensure it follows best practices for performance and cross-browser compatibility. Provide implementation instructions for [PLATFORM: e.g., Google Tag Manager, Shopify, WordPress, or a custom website]. Include a section on how to validate the script works using [TOOL: e.g., browser console, Google Analytics DebugView, or Hotjar recordings].
Example Output
```javascript
// Dynamic Ad Creative Adjustment Based on Scroll Depth
// Purpose: Swap ad creatives when users scroll past 50% of the page to improve engagement
// Platform: Custom website (compatible with Google Tag Manager)
// Validation: Use browser console or Hotjar recordings
// Configuration
const scrollThreshold = 0.5; // 50% scroll depth
const originalCreativeId = 'ad-creative-1';
const alternativeCreativeId = 'ad-creative-2';
// DOM Elements
const adContainer = document.getElementById('ad-container');
const originalCreative = document.getElementById(originalCreativeId);
const alternativeCreative = document.getElementById(alternativeCreativeId);
// Track scroll events
window.addEventListener('scroll', () => {
const scrollPercentage = window.scrollY / (document.body.scrollHeight - window.innerHeight);
if (scrollPercentage >= scrollThreshold && originalCreative.style.display !== 'none') {
// Hide original and show alternative creative
originalCreative.style.display = 'none';
alternativeCreative.style.display = 'block';
// Log event for analytics
if (typeof dataLayer !== 'undefined') {
dataLayer.push({
'event': 'ad_creative_swapped',
'original_creative': originalCreativeId,
'new_creative': alternativeCreativeId,
'scroll_depth': Math.round(scrollPercentage * 100)
});
}
}
});
// Fallback: Show alternative creative if original fails to load
originalCreative.addEventListener('error', () => {
originalCreative.style.display = 'none';
alternativeCreative.style.display = 'block';
});
// Validation Instructions:
// 1. Open browser console (F12 > Console)
// 2. Scroll past 50% of the page
// 3. Verify the creative swap occurs by checking network requests or visual change
// 4. Check dataLayer.push() events in GTM preview mode or browser console
// Implementation Notes:
// - Add this script to your website's <head> or before closing </body> tag
// - Ensure ad-container and creative IDs match your HTML structure
// - Test in multiple browsers (Chrome, Firefox, Safari)
// - Monitor performance impact using Chrome DevTools > Performance tab
